This 3D model represents one of the largest and most complex in the series, consisting of a partial torso from the diaphragm to the proximal thigh with a complete abdominal cavity preserving varying levels of dissection. This 3D model also records the rare, simultaneous occurrence of indirect and direct inguinal hernias allowing for a consideration of the anatomical underpinnings for both conditions. Given the scale of the dissection this 3D model description is divided into discrete parts based on views and regions.The diaphragmThe diaphragm is preserved on the model’s superior aspect, with both domes and costodiaphragmatic recesses visible despite some distortion from rib removal. The fibrous pericardium rests on the central tendon, with the terminal inferior vena cava seen in the caval foramen. Lateral to this lies the oesophagus in the oesophageal hiatus, and the descending thoracic aorta approaching the aortic hiatus near the vertebrae. The epigastric and hypochondriac regionsIn the abdomen, removal of the anterior wall, greater omentum, and much of the GI tract reveals retroperitoneal structures. The terminal oesophagus enters just left of the liver. With the stomach removed, the pancreas is fully exposed from head to tail, reaching the spleen in the left hypochondrium. Above it, the splenic and common hepatic arteries span the narrow space between pancreas, diaphragm, and liver. The tortuous splenic artery divides near the splenic vein; the common hepatic gives rise to the gastroduodenal and right gastric arteries, superficial to the portal vein. The superior mesenteric vessels pass near the pancreatic head, and the ileocolic artery leads to the caecum. The inferior mesenteric vein arises from the superior rectal vein and crosses the descending aorta. Below the liver, the gallbladder lies between the lobes. On the left, renal vessels pass deep to the pancreas, with ureters descending across the psoas muscles. The umbilical and lumbar regionsMost abdominal organs in the umbilical and lumbar regions have been removed to reveal the posterior abdominal wall. Centrally, the descending aorta and inferior vena cava are prominent, with testicular vessels traceable toward the inguinal region. Two right lumbar arteries branch from the aorta, and the inferior mesenteric artery gives rise to the left colic, sigmoid, and superior rectal arteries. On the right, subcostal, iliohypogastric, and ilioinguinal nerves are visible, along with the circumflex iliac artery.The hypogastrium and iliac regionsThe abdominal aorta bifurcates into the common, internal, and external iliac arteries, with matching iliac veins merging into the inferior vena cava. The obturator artery, ureters, and testicular vessels are visible. In the true pelvis, the peritoneum covers the bladder, while the rectum remains obscured. The right iliac fossa contains the terminal ileum, caecum, and appendix, with nearby vessels and nerves. On the left, the sigmoid colon crosses the iliac fossa, where an epiploic appendage extends into an indirect hernia near the inferior epigastric artery. The inguinal region and perineumThis model uniquely preserves both direct (right) and indirect (left) inguinal hernias, with the inferior epigastric vessels retained for anatomical orientation. The right hernia lies medial to these vessels; the left hernia sac extends laterally into the spermatic cord, containing an epiploic appendage. The perineum reveals the penis, testes, and spermatic cords. On the right, the cord remains intact; on the left, it’s opened, showing a varicose testicular vein linked to the indirect hernia. The thighThe femoral triangle has been dissected on both thighs. On the right, the femoral sheath was removed to reveal the femoral artery, vein, deep inguinal lymph nodes, and femoral nerve. On the left, a broader view exposes anterior and medial thigh muscles, with the femoral artery, profunda femoris, and circumflex iliac artery visible. The model ends mid-thigh, showing cross-sectional anatomy including the femoral shaft, vessels, and muscles in the subsartorial canal.

This 3D printed model presents a detailed anatomical view of the left upper limb, extending from the scapula to the hand. Most of the skin and fascia have been removed to expose the muscles, vessels, and nerves, while select regions (such as the dorsum of the scapula, proximal arm, and hand) retain superficial coverings for reference. Veins and Superficial StructuresThe cephalic, basilic, and median cubital veins are preserved, clearly demonstrating the superficial venous system from the wrist to the deltopectoral groove and brachial vein. Axilla and ShoulderIn the axillary region, the deltoid, supraspinatus, infraspinatus, teres minor and major, and subscapularis muscles are shown in cross-section. Key tendons — including those of the latissimus dorsi, coracobrachialis, and pectoralis major — are also retained.Portions of the axillary artery and vein are visible, along with the lateral cords of the brachial plexus. Several terminal branches are displayed, including the ulnar, median, musculocutaneous, axillary, radial, and upper subscapular nerves. Arm and Forearm DissectionThe model continues distally with a full view of the anterior and posterior compartments of the arm, displaying both muscle structure and the deep neurovascular pathways. In the cubital fossa, part of the bicipital aponeurosis remains intact.In the forearm, superficial flexor and extensor muscles are dissected from their origins to their tendinous insertions. A section of deep forearm fascia over the extensor compartment is retained for structural orientation. At the distal forearm, the radial and ulnar arteries and the median nerve are clearly visible. This model is ideal for teaching and studying upper limb anatomy, offering detailed views of musculature, vascular structures, and nerve pathways with a focus on both surface and deep anatomical relationships.

This liver specimen displays notable differences compared to a typical liver. It is less wedge-shaped and elongated in the superoinferior dimension, resulting in a greater vertical height when viewed from the posterior. Size- Measures approximately 18 cm along the midclavicular line.- Typical livers measure under 16 cm in this dimension.- The increased length suggests mild hepatomegaly (enlargement). Important Notes- Size estimates may be affected by specimen preservation and fixing, which can cause some distortion.- Diagnosing hepatomegaly based on a single measurement is limited and varies with individual anatomy, measurement technique, sex, and body mass index (BMI). Anatomical VariationsThis specimen does not match common anatomical variations often confused with hepatomegaly such as:- Riedel’s lobe: a downward projection of the right lobe- Beaver tail liver: elongated left lobe- Papillary process from the caudate lobe

This detailed 3D anatomical model preserves the deep foregut organs, including the descending, horizontal, and ascending parts of the duodenum, the pancreas, and the spleen. It offers a unique and insightful view into the complex anatomy of this region. DuodenumA small window is opened in the duodenum to reveal the plicae circularis, the characteristic circular folds of the proximal small intestine. This contrasts with the prominent rugae of the stomach, providing an educational comparison of mucosal patterns in the upper gastrointestinal tract. PancreasThe pancreas is preserved in its natural anatomical position, nestled within the curvature of the duodenum. The head of the pancreas is clearly visible, including the distinct uncus located at its distal margin, adjacent to the origin of the superior mesenteric artery (SMA). In this model, the SMA is already divided into its major named branches, highlighting its vascular complexity.The body of the pancreas features the superior margin where the celiac trunk, sectioned from the descending abdominal aorta, is located. The complete splenic artery is shown following its tortuous path from the celiac trunk to the spleen. The model also displays the origins of the left gastric artery and the common hepatic artery branching from the celiac trunk.Adjacent to the celiac trunk, a segment of the splenic vein is visible emerging from the pancreas’ capsule. This vein runs alongside the splenic artery en route to the spleen. Additionally, a portion of the superior mesenteric vein is seen adhering to the posterior pancreas, representing its path before converging with the splenic vein to form the hepatic portal vein.The tail of the pancreas is embedded within the splenic capsule, partially obscuring the splenic artery branches before entering the spleen. For more detailed views of this region, refer to our other spleen models (MP1130 and MP1134), which illustrate further anatomical and spatial relationships.

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.
