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.

Description

Test your knowledge on the anatomy of the abdomen and pelvis with this exam focused on the pelvic walls and associated structures. This quiz covers key concepts including the greater and lesser omentum, as well as the ileum. Prepare to solidify your understanding of these essential anatomical details.
