Study Notes
Digestive System Anatomy
- Lesser Omentum: Connects the lesser curvature of the stomach to the liver and the beginning of the duodenum.
- G Cells: Located in the pyloric mucosa, secrete gastrin.
- Falciform Ligament: Connects the liver to the abdominal wall.
- Inguinal Ligament: Formed by the inferior border of the external abdominal oblique muscle.
- Hepatorenal Ligament: Attaches to the caudate lobe of the liver.
- Internal Abdominal Oblique Muscle Fibers: Run cranioventrally (upward, forward, and medially).
- Superficial Inguinal Ring: A slit in the aponeurosis of the external abdominal oblique muscle.
- Retroperitoneal Organs: Organs located behind the peritoneum, including the pancreas, kidneys, and part of the duodenum.
- Omental Bursa (Lesser Sac): A large recess in the peritoneal cavity behind the stomach, communicating with the greater omentum via the epiploic foramen.
Abdominal Muscles and Structures
- Rectus Sheath: Formed by the aponeuroses of the external, internal oblique, and transversus abdominis muscles.
- Caesarean Section Incisional Layers: Layers incised during a caesarean section include skin, fat, rectus sheath, rectus abdominis, parietal peritoneum, and uterine muscles. Aponeuroses of the external and internal oblique muscles are also usually cut.
