Parotid Gland and Facial Nerve dissection

This high-resolution 3D model features a head and neck specimen sectioned just off the midsagittal plane, preserving critical midline structures often absent in similar models. Ideal for anatomical education, this model offers enhanced visibility due to fixative-induced brain shrinkage, exaggerating spaces between brain and skull.Key Features:Midline Anatomy Preserved:Includes the falx cerebri (anterior portion), septum pellucidum, interventricular foramen (of Monro), and nasal septum.Ventricular & Endocranial Structures:Clear views of the lateral and third ventricles, cerebral aqueduct, fourth ventricle, infundibulum, pituitary gland, and sphenoid sinus.Vascular Highlights:Displays the left vertebral artery, posterior cerebral artery (cross-section), and anterior cerebral artery branches around the corpus callosum.Detailed Nasal & Pharyngeal Regions:Shows relationships between the nasal septum, palate, auditory tube opening, and naso-/oropharynx.Laryngeal and Tracheal Anatomy:Includes epiglottis, arytenoid, thyroid cartilages, hyoid bone, and cross-sectional views of the vestibule, vestibular and vocal folds.This model provides a unique perspective of internal head and neck anatomy, combining anatomical depth with high educational value.

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 3D model preserves the several deep cerebral and diencephalic structures through to the proximal medulla oblongata and compliment the other isolated brainstem (MP1101) in our series.Superiorly, on the right side of the 3D model, the lentiform (lenticular) nucleus is in place and the corona radiata of the internal capsule is seen emerging around it. On the left, the lentiform nucleus is absent, but the caudate nucleus head and body are present medially on both sides, wrapping medial to the preserved internal capsule margins and leading to the amygdaloid bodies on each side. The thalami are present bilaterally, and the third ventricle is opened slightly in the midline inferior to the epithalamus (pineal gland).Anteriorly, the cerebral peduncles are present, with the optic nerves extending from the preserved chiasm and tracts. The interpeduncular region is exposed with both the mammillary bodies and the sectioned infundibulum visible. Caudal to the interpeduncular region is the pons preserving the origins of the middle cerebellar peduncles as well as the origins of cranial nerves V, VII, and VIII. The portion of the medulla oblongata preserved possesses prominent pyramids and olives.Posteriorly, the superior and inferior colliculi sit just superior to the sectioned superior cerebellar peduncles, and the fourth ventricle is opened to expose the rhomboid fossa and features of the floor: the medial eminence, facial colliculus, hypoglossal triangle, the vestibular triangle and the vagal triangle.

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 detailed 3D model presents a transverse cross-section of the thorax at the level of the T6 vertebra, offering a clear view of thoracic anatomy in relation to skeletal, vascular, respiratory, and cardiac structures.Key Features:Posterior Structures- Begins medially with the spinal cord within the vertebral canal- Costovertebral joints of the 6th ribs are visible, along with surrounding ribs forming the thoracic wall Anterior Thoracic Wall- Costosternal joints show the connection between ribs and sternumMajor Thoracic Organs- Oesophagus located anterior to the vertebral body- Descending aorta situated lateral to the vertebral bodyLungs and Pleural Cavities- Within the pleural spaces (lined by parietal pleura):- Right lung: middle and inferior lobes- Left lung: inferior lobeHeart and Mediastinum- In the middle mediastinum, the heart is shown within the pericardium, sectioned to display internal anatomy:- Left atrium (posterior)- Aortic valve, right ventricle, and right atrium in clockwise order

This 3D model provides a combined midsagittal section through the head and superior neck coupled with a deep dissection into the infratemporal fossa region and superficial dissection of the scalp. In the preserved midsagittal section there is preservation of the endocranial contents, the nasal and oral cavities, and the pharynx to the level of the laryngeal cartilages. The nasal cavity is preserved nearly intact, except for a small window excised into the middle nasal concha to expose the ethmoid air cells. A very large sphenoid sinus exists in the individual just superior to the torus of the auditory tube in the nasopharynx. The oral cavity and laryngopharynx are undissected, with the larynx only preserve just distal to the level of the arytenoid cartilages and not including a clear set of vocal folds.Within the endocranial cavity, the sectioned brain is slightly off the midagittal plane, such that neither the superior sagittal sinus nor the third ventricle are clearly defined - but the lateral ventricle is open and part of the fourth ventricle is preserved between the pons and cerebellum. The gyri and sulci of the cerebrum are not well separated, but the cingulate gyrus and corpus callosum can be separated. Cross-sectioned views of the optic tract, pituitary gland, superior and inferior colliculi, superior cerebellar peduncle, and transition between the medulla oblongata and spinal cord are all visible. The tentorium cerebelli and confluence/transverse sinus is positioned between the cerebellar hemisphere and occipital lobe. Small portions of the posterior inferior cerebellar artery, vertebral arteries, basilar artery, and posterior cerebral and anterior cerebral arteries are visible in section.On the opposing side of the model, a superficial and deep dissection has opened a large window into the anatomy of the lateral scalp and infratemporal fossa. Across the scalp there is a well preserved posterior auricular nerve and superficial temporal artery highlighted on the superficial surface of the temporalis muscle. Anteriorly, the temporalis has been dissected to expose the deep temporal arteries arising from across the maxillary artery.The deep level of dissection has exposed parts of the infratemporal fossa (through partial removal of the mandibular ramus and corpus) and dissection of retromandibular tissues. At the inferior margin of the dissection window, the cut edge of the retromandibular vein lies adjacent to the submandibular gland and the ascending path of the facial artery as it cross towards to angle of the mouth. Just superior to the cut retromandibular vein is the posterior belly of the digastric muscle, overlying a small exposure of the deeper internal jugular vein.Just posterior to the retained ascending ramus of the mandible are the external carotid artery and the occipital artery (running in parallel prior to passing posteriorly). Tracing the external carotid artery superiorly, the posterior auricular artery, superficial temporal artery, and maxillary artery are all visible. The maxillary artery passes deep to the lateral pterygoid muscle and into the infratemporal fossa, reappearing superior to the lateral pterygoid as it passes into the pterygomaxillary fissure. Along its course, it gives rise to the posterior deep temporal artery, the inferior alveolar artery (which is exposed in the dissected mandibular corpus), the anterior deep temporal artery, and the posterior superior alveolar artery. Finally, the inferior alveolar nerve can be seen coursing within the opened mandibular corpus, and the lingual nerve resting on the medial pterygoid. The buccinator muscle is also retained, with the distal part of the parotid duct preserved as it enters the muscle towards the oral mucosa.

This 3D printed model presents a superficial dissection of the right distal arm, forearm, and hand, showcasing key vascular, nervous, and muscular anatomy.Distal Arm & Cubital FossaThe arrangement of the biceps tendon, brachial artery, and median nerve is visible from lateral to medial. The bicipital aponeurosis has been removed to expose deeper structures. The ulnar nerve is reflected from the cubital tunnel, and the radial nerve with its branches is visible near the supinator muscle. Forearm AnatomyOn the anterior forearm, superficial flexors (pronator teres, FCR, FDS, FCU) are preserved; palmaris longus is absent. The radial artery is exposed; the ulnar artery is not visible. Posteriorly, extensors from the common origin are visible, including ECRB, ED, EDM, and ECU. The APL, EPB, and EPL are also shown wrapping around the radius. Hand & SnuffboxThe anatomical snuffbox reveals the radial artery in its floor and cutaneous branches of the radial nerve. The palmar side displays thenar/hypothenar muscles, lumbricals, flexor tendons, and the median nerve beneath the flexor retinaculum. A superficial branch of the radial artery crosses the retinaculum.Ideal for anatomical education, this print offers a clear view of key structures in the distal upper limb.
