Common Findings in Abdominal Cadaveric Dissection
Key Anatomical Observations
| Structure | Common Observation/Variation |
|---|---|
| Greater Omentum | Often draped over the transverse colon and small intestines, it varies significantly in fat content. |
| Liver/Gallbladder | The gallbladder frequently shows evidence of previous cholelithiasis or peri-cholecystic adhesions. |
| Celiac Trunk | Common site for arterial branching variations (e.g., replaced or accessory hepatic arteries). |
| Kidneys/Ureters | Commonly noted renal cysts; the ureters may show variations in crossing the iliac vessels. |
| Mesentery | Rich in lymphatic vessels and nodes, often visible along the arterial arcades of the jejunum and ileum. |
NEET PG “Must-Know” Surgical Anatomy
- Porta Hepatis: Posterior to anterior—Portal vein, Hepatic artery, Common bile duct.
- Morison’s Pouch (Hepatorenal recess): The most dependent space in the supine position; a common site for fluid accumulation (blood/pus).
- Appendicular Anatomy: The base of the appendix is constant at the McBurney’s point (junction of lateral 1/3 and medial 2/3 of a line from ASIS to the umbilicus), but the tip position is highly variable (retrocecal is most common).
- Hesselbach’s Triangle: Boundaries—Inferior epigastric vessels (lateral), Rectus abdominis (medial), Inguinal ligament (inferior). The site of direct inguinal hernias.
