Surface Projections of Abdominal Organs

Surface Projection of the Ileocaecal Junction

The ileocaecal junction marks the transition between the small intestine and the large intestine. It is a vital anatomical region, primarily consisting of the cecum, ileum, and associated structures such as the ileocecal valve and appendix.

Location and Clinical Significance

The ileocaecal junction is typically located in the right lower quadrant of the abdomen, near McBurney's point. It plays a key role in controlling the passage of chyme from the ileum into the cecum.

Key Structures

• Cecum: A pouch-like structure forming the beginning of the large intestine.
• Ileum: The final segment of the small intestine responsible for nutrient absorption.
• Ileocecal Valve: A sphincter that regulates flow between the ileum and cecum.
• Appendix: A small, vestigial organ with potential immunological functions.

Clinical Considerations

Conditions like appendicitis and ileocecal tuberculosis affect this region and can present with right lower abdominal pain. Physicians often assess surface projections during diagnosis.
