The haustra (sg.: haustrum) of the colon are the small pouches caused by sacculation (sac formation), which give the colon its segmented appearance. The teniae coli run the length of the colon.

2024年12月10日 · The haustral folds represent folds of mucosa within the colon. The haustra (singular: haustrum) refer to the small segmented pouches of bowel separated by the haustral folds. They are formed by circumferential contraction of the inner muscular layer of the colon.

The haustra of the colon (singular haustrum) are the small pouches caused by sacculation, which give the colon its segmented appearance. The taenia coli runs the length of the large intestine.

2023年10月30日 · sigmoid colon; You can recognize it easily through several distinct morphological features like semilunar folds and pouches called haustra. In addition, taeniae coli are specific to the colon together with appendices epiploicae.

2023年7月31日 · Haustra are saccules in the colon that give it its segmented appearance. Haustral contraction is activated by the presence of chyme and serves to move food slowly to the next haustra, along with mixing the chyme to help with water absorption.

2023年7月16日 · This involves a sudden, uniform peristaltic contraction of smooth muscle of the gut which originates at the transverse colon and rapidly moves formed faeces into the rectum, which is normally empty. The result of this is feeling the urge to defecate.

2023年9月11日 · The large intestine has several distinct anatomical characteristics; the omental appendices, teniae coli and haustra. Omental or epiploic appendages are fat filled pouches of peritoneum that are attached externally to the walls of the large intestine.

2025年1月13日 · Haustra (singular: haustrum) are a key feature of the colon, the large intestine. These pouch-like structures are formed due to the unique anatomy of the colon and play an important role in digestive processes.

Since the taeniae are shorter than the length of the colon itself, their tethering action in relation to the circular muscle results in the characteristic haustral sacculations. The colonic haustra are thus organized into three distinct rows, each of which has characteristic anatomic relationships (6).

Haustra are the small, pouch-like structures that form along the length of the colon due to its unique muscle arrangement. These sacculations create the characteristic segmented appearance of the colon and play an important role in the process of digestion and absorption, as they allow for more efficient mixing and movement of the intestinal ...
