Lung Slab, Hilum removed

This high-quality 3D model presents a sagittal section of the right lung, focused on the hilum, where key anatomical structures enter and exit the lung. It serves as an essential tool for understanding pulmonary vascular and bronchial anatomy, with clear orientation from apex to base and medial to lateral surfaces.Key Features:Hilum Structure:- The hilum marks the transition between visceral and parietal pleura and serves as the lung’s only anatomical connection to the body via the pulmonary ligament.- Major structures entering the lung at this point include:- Pulmonary artery (superior in the hilum) – carrying deoxygenated blood from the heart.- Superior and inferior pulmonary veins (anterior and inferior) – returning oxygenated blood to the heart.- Right main bronchus and its lobar branches – located posteriorly in the hilum. - Associated nerves and lymphatics. Visible Anatomical Landmarks:- Cardiac impression (formed by the right atrium) is visible just anterior to the hilum.- The oesophageal groove is preserved along the posterior surface, tracing the path of the descending oesophagus.- Oblique and horizontal fissures are well-defined on the lateral surface, demarcating the lung's three lobes.- Hilar lymph nodes are observed around the medial hilum.Lung Surfaces:- Diaphragmatic surface (inferior), showing the concave interface with the diaphragm.- Costal visceral surface (posterior), where the lung contacts the thoracic wall.

This 3D model provides a detailed sectional view of the right lung, serving as a complementary piece to the TW 63 Right Lung Hilum and contrasting with the TW 61 Left Lung Section.It highlights the macrostructure of the lung from apex to base, offering a valuable perspective for anatomical study and comparison between lung sides.Key Features:Lobar Organization:- Clearly defined oblique and horizontal fissures segment the lung into the superior, middle, and inferior lobes.- The depth of these fissures is visible, showing their extension into the internal lung structure. Surface Impressions:- Prominent rib impressions run longitudinally from the apex to the base on the lateral aspect, indicating close contact with the thoracic cage.Diaphragmatic Surface:- The deeply concave base reflects the domed shape of the right diaphragm, which is elevated in life due to the position of the underlying liver.

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.
