Female pelvis deep dissection

This detailed 3D printed specimen provides a unique dorsal view of the head, neck, thorax, abdomen, and gluteal regions, highlighting the central nervous system and segmental nerves in anatomical context. The model reveals deep structures through extensive removal of posterior elements, including the posterior cranium, vertebral arches, and parts of the thoracic and gluteal walls.Cranial and Cervical StructuresThe posterior skull is removed to display a coronal section of the cerebral hemispheres, separated by the falx cerebri and bordered by a preserved superior sagittal sinus. The cerebellum is removed, exposing the fourth ventricle, pons, medulla oblongata, and cranial nerves VII–XII. The vertebral arteries are visible ascending through the transverse foramina and curving toward the foramen magnum. The cervical and brachial plexus roots are shown resting on scalene muscles and major vessels, extending into the axilla. Axilla and Upper ThoraxThe scapulae are partially (left) or fully (right) removed, allowing visualization of the brachial plexus and axillary vessels.On the left, parts of deltoid, infraspinatus, and teres minor remain, while the long thoracic nerve, lateral thoracic artery, and subscapular branches are preserved.On the right, the axillary nerve and posterior circumflex humeral artery are shown passing toward the surgical neck of the humerus. Thoracic Spine and Intercostal NervesA laminectomy reveals the spinal cord, dorsal roots, and ganglia.On the right, the posterior thoracic wall is removed (ribs 2–12), exposing the lung and diaphragm.On the left, ribs 3–5 are retained to show intercostal musculature and nerve positioning, with the full set of intercostal nerves preserved.Lumbar Region and AbdomenThe lumbar spinal cord is opened to show the conus medullaris and cauda equina.On the right, the quadratus lumborum is removed, exposing subcostal and lumbar nerves along the psoas.On the left, the subcostal nerve, kidney, and jejunum are visible through an opened peritoneal cavity. Gluteal and Pelvic DissectionIn the gluteal region, gluteus maximus is removed bilaterally:Left side: Gluteus medius is preserved; the superior and inferior gluteal arteries and nerves, internal pudendal vessels, and the sciatic nerve are visible relative to the piriformis and lateral rotators.Right side: Deeper dissection reveals the lumbar and sacral plexuses within the true pelvis. This model offers a rare, continuous view of deep axial anatomy, perfect for advanced anatomical study, neuroanatomy training, and surgical reference.

This detailed 3D model displays the left half of a female pelvis, sectioned midsagittally, and extending to the proximal mid-thigh.Pelvic Organs & Peritoneum- Visible structures: Urinary bladder, uterus, vagina, and rectum (from anterior to posterior).- The peritoneum is preserved, showing the vesicouterine and rectouterine pouches.- The broad ligament, uterine tube, fimbriae, and left ovary are identifiable near the pelvic brim. Vessels & Nerves- Common and external iliac arteries pass toward the subinguinal space, alongside the common iliac vein and psoas major.- The ureter crosses over these vessels. - The femoral nerve is visible between psoas major and iliacus muscles. Anterior Thigh & Inguinal Region- Superficial fascia removed, exposing thigh structures up to the perineal edge.- Femoral triangle dissected to show:- Femoral artery and vein, with the vein receiving tributaries from the great saphenous, superficial circumflex iliac, external pudendal, and deep pudendal veins.- Femoral nerve lateral to the artery.- Anterior cutaneous nerves and part of the lateral cutaneous nerve over the sartorius muscle. - Inguinal lymph nodes beneath the inguinal ligament. Posterior Gluteal Region- Gluteus maximus removed to reveal deeper gluteal muscles.- Piriformis reflected, exposing:- Sciatic nerve, formed by tibial and common peroneal nerves.- Superior and inferior gluteal arteries. - Posterior cutaneous nerve of the thigh running parallel to the sciatic nerve.- Obturator internus, gemelli, and quadratus femoris muscles exposed.- Internal pudendal artery and pudendal nerve track toward the ischioanal fossa.- Their branches, including the inferior rectal nerve, are visible near the pelvic diaphragm and external anal sphincter.

This 3D printed model provides a detailed ventral view of the head, neck, thorax, abdomen, and proximal thighs, offering insight into the central nervous system, nerve plexuses, and major vascular structures. It serves as a complementary piece to the dorsal dissection model (MP1400).Brain and Upper SpineThe facial skeleton is removed, exposing both cerebral hemispheres, parts of the Circle of Willis, and key arteries (vertebral, basilar, AICA, labyrinthine). Several cranial nerves (II, III, V, VI) and the right internal carotid artery are preserved. Below, the anterior spinal cord, vertebral arteries, and cervical and brachial plexus roots are visible, along with CN X, CN XII, and the sympathetic trunks. Axillae and Upper LimbsThe anterior thoracic wall, clavicles, and first ribs are removed to expose both axillae, with clear views of the brachial plexus, axillary arteries, and surrounding musculature. The proximal upper limbs are preserved to mid-arm level. Thorax and Lumbar RegionThe spinal cord extends to the conus medullaris, with ventral nerve roots and sympathetic chains visible throughout. Splanchnic nerves, intercostal nerves, and abdominal wall nerves (e.g., ilioinguinal, genitofemoral, femoral) are preserved. On the right, removal of the psoas muscle exposes the lumbar plexus.Pelvis and Proximal ThighThe pelvic viscera are removed, but the pelvic floor, rectum, and lumbosacral plexus remain. Obturator nerves are visible entering the obturator canals, and the femoral vessels are retained in both femoral triangles. This model is ideal for studying ventral CNS access, neurovascular pathways, and regional anatomical relationships across the entire torso.

This 3D model preserves a right male pelvis sectioned just superior to the L5 vertebra and sectioned at the midsagittal plane, with the thigh preserved to near the midshaft of the femur. This specimen compliments our LW 91 female hemipelvic specimen and thigh. The common iliac artery is preserved with several key branches visible, particularly the distribution of the internal iliac within the true pelvis. Several major vessels including the obturator artery and the partially obliterated umbilical artery passes towards the anterior abdominal wall (to form the medial umbilical ligament) and gives off the superior vesicle artery; while the roots of the iliolumbar, superior gluteal, inferior gluteal and internal pudendal artery are visible lateral to the urinary bladder. The ureter descends superficial to these vessels to approach the urinary bladder which is covered with peritoneum in this model. The ductus deferens is exposed from the entry into the space via the deep inguinal ring and passing posteriorly (though sectioned from its normal insertion pathway and resting on the internal iliac artery). Adjacent to the ureter and on the superficial surface of the psoas major muscle is an enlarged iliac lymph node and part of the lymphatic vasculature ascending along the external iliac artery. The majority of the pelvis has been left undissected, allowing for an appreciation of the rectovesicular pouch and the exposed superior rectal artery and vein approaching the preserved portion of rectum. In cross section, the rectum, seminal vesicle and prostate are visible (the section plane preserves parts of both the prostatic urethra and ejaculatory duct).In the anterior thigh the borders and contents of the femoral triangle are well-preserved, with partial coverage by the flap of the anterior abdominal wall. Posteriorly the skin over the gluteal region and the gluteus maximus muscle have been removed as sequential windows to expose the gluteus medius and minimum muscles, the piriformis, the obturator internus with gemelli muscles, and the quadratus femoris muscle. The superior and inferior gluteal arteries are maintained superior and inferior to the piriformis, respectively; with the sciatic nerve exiting inferior to piriformis before passing deep to the retained portion of the gluteus maximus.

This detailed 3D model captures the internal surface of the anterior abdominal wall—a region often removed or damaged during dissections. It complements our A8 abdominal specimen, where the anterior wall has been removed, providing a clear view of key muscle and connective tissue structures. Key Features:Muscle Fibers & Aponeurosis:The horizontally oriented transversus abdominus muscle fibers converge toward their aponeurosis (tendon sheet), visible especially along the specimen’s superior margins. Arcuate Line:Located in the lower third of the model, this landmark marks where the aponeurosis shifts relative to the rectus abdominus muscle.- Above the arcuate line: Aponeurosis fibers split evenly around the rectus abdominus.- Below the arcuate line: All aponeurotic fibers pass anteriorly to the rectus abdominus, reflecting a change in abdominal wall structure. Vascular Structures:Inferior Epigastric Arteries & Veins:These vessels originate from the external iliac arteries and veins, ascending superiorly through the anterior abdominal wall. Hesselbach’s Triangle:On the right side of the model, the orientation of the inferior epigastric artery relative to the rectus abdominus muscle defines the apex of the inguinal (Hesselbach’s) triangle—a critical anatomical region often associated with direct inguinal hernias. (Note: The inguinal ligament forming the base of this triangle is not present in this specimen.) Embryological Remnant: Median Abdominal Ligament:Positioned midline between the two rectus abdominus muscles, this fold of parietal peritoneum covers the urachus, a fibrous remnant from embryological development extending from the bladder to the umbilicus.

This detailed 3D printed model presents the male posterior abdominal wall from the diaphragm down to the pelvic brim, including the pelvis and proximal thigh.A focused pelvic and thigh version is also available (MP1770).Muscular Anatomy & DiaphragmThe parietal peritoneum is removed to expose the key muscles of the posterior abdominal wall: psoas major, quadratus lumborum, transversus abdominis, and iliacus below the iliac crest. The diaphragm shows distinct muscular fibers originating from the thoracic cage and lumbar vertebrae (right crus L1–L3, left crus L1–L2), connected by the median arcuate ligament. Major diaphragmatic openings for the esophagus, aorta, and inferior vena cava are visible, although the aorta is removed. NervesSomatic nerves are clearly identifiable, including the subcostal, iliohypogastric, and ilioinguinal nerves (which arise together in this specimen), the lateral cutaneous nerve of the thigh, the genitofemoral nerve (on psoas), and the femoral nerve situated between psoas and iliacus. The sympathetic trunks run alongside the lumbar vertebrae. Vessels & KidneysThe aorta and inferior vena cava are transected at L3, with the aortic bifurcation positioned slightly higher than usual. The renal arteries and veins are preserved, though their full origin is partly obscured by the absence of the great vessels. Both kidneys are dissected free from surrounding fat, showing the typical lower position of the right kidney. The ureters are visible descending from the renal hilum, passing medial to the psoas before crossing the pelvic brim into the true pelvis. This model offers an exceptional view of the complex anatomy of the posterior abdominal wall, pelvis, and proximal thigh, making it ideal for advanced anatomical study, surgical planning, and clinical reference.

This large, multipart 3D printed specimen showcases detailed anatomy of the head, neck, thorax, axillae, and upper limbs.Head and Neck:The calotte has been removed ~2?cm above the orbits to expose the brain and endocranial cavity. A transverse cerebral section shows grey and white matter, lateral ventricles, and choroid plexus. The right side retains skin and fascia, false-coloured to highlight facial and neck angiosomes. The left side reveals facial expression and mastication muscles, and infratemporal structures including the lingual nerve and terminal branches of the external carotid artery. The carotid sheaths are opened bilaterally, exposing the common, internal, and external carotid arteries, and vagus nerves. The sternocleidomastoid and internal jugular veins are mostly removed. On the right, the great auricular and hypoglossal nerves are visible, along with the stylohyoid ligament and supra-/infrahyoid muscles. The thyroid gland is prominent, with preserved superior and inferior thyroid vessels.Root of the Neck and Axilla:On the left, partial clavicle removal reveals the first rib, anterior scalene, and brachial plexus roots (C5–T1) forming trunks between scalene muscles. The subclavian artery passes posterior to scalenus anterior, transitioning to the axillary artery, closely related to the brachial plexus cords.The left axilla displays brachial plexus divisions and cords. The formation of the median nerve around the axillary artery is distinct. The ulnar, musculocutaneous, axillary, thoracodorsal, and long thoracic nerves are clearly identified with their courses and muscular targets.On the right, the clavicle and subclavius muscle are intact, showing the cervico-axillary canal. Pectoralis major and minor have been reflected, exposing deeper structures.Thorax:A window in the left thoracic wall reveals the mediastinum. The left lung has been removed. Intercostal spaces are visible beneath the parietal pleura; neurovascular bundles are identifiable posteriorly. The heart is exposed without pericardium, showing the left atrium and ventricle, pulmonary vessels, aorta, and both left vagus and recurrent laryngeal nerves. The right thoracic wall remains intact, displaying intercostal and upper limb muscles. From below, the right lung, pleural cavities, and diaphragmatic heart surface are visible. Posterior thoracic skin and fascia are intact, showing cutaneous nerve distribution.Size: 50 x 20 x 41 cm
