    Study Notes

    Abdominal Cavity and Pelvis

    • The abdominal cavity contains key organs except for the lungs, which reside in the thoracic cavity.
    • The peritoneum is a critical membrane; the part that lines the abdominal walls is known as the parietal peritoneum.

    Stomach Anatomy

    • The fundus is located above the cardiac orifice, projecting left and upward.
    • The stomach's body extends between the cardiac orifice and the incisura angularis.
    • The lesser curvature is the right border of the stomach, from the cardiac orifice to the pylorus.
    • The greater curvature is significantly longer, stretching from the left of the cardiac orifice.

    Omentum

    • The greater omentum connects the greater curvature of the stomach to the transverse colon.
    • The lesser omentum attaches to the lesser curvature of the stomach, linking it to the ligamentum venosum and the porta hepatis on the liver's underside.

    Intestinal Structure

    • The small intestine comprises the duodenum, jejunum, and ileum; the cecum is not part of it.
    • Mesenteries are two-layered peritoneal folds that connect sections of the intestines to the posterior abdominal wall.

    Esophagus

    • The esophagus is a muscular tube approximately 25 cm long, connecting the pharynx to the stomach.
    • It enters the abdomen via an opening in the right crus of the diaphragm.

    Organ Classification

    • An organ is termed intraperitoneal when it is almost completely encased in visceral peritoneum.
    • Retroperitoneal organs lie behind the peritoneum and are partially covered by it.
