The cecum or caecum is a pouch within the peritoneum that is considered to be the beginning of the large intestine. [1] It is typically located on the right side of the body (the same side of the body as the appendix, to which it is joined). The word cecum (/ ˈ s iː k əm /, plural ceca / ˈ s iː k ə /) stems from the Latin caecus meaning ...
Cecum and beginning of ascending colon. The cecum is a pouch marking the division between the small intestine and the large intestine. It lies below the ileocecal valve in the lower right quadrant of the abdomen. [33] The cecum receives chyme from the last part of the small intestine, the ileum, and connects to the ascending colon of the large ...
It also includes the appendix, which is attached to the cecum. Its length is about 1.5 m, and the area of the mucosa in an adult human is about 2 m 2 (22 sq ft). [19] The longest part of the large intestine is the colon whose main function is to absorb water and salts. [21] The large intestine begins at the cecum, where the appendix is located
In terms of diameter, the cecum is the widest, averaging slightly less than 9 cm in healthy individuals, and the transverse colon averages less than 6 cm in diameter. [14] The descending and sigmoid colon are slightly smaller, with the sigmoid colon averaging 4–5 cm (1.6–2.0 in) in diameter.
The cecum is a pouch-like structure of the large intestine, located at the junction of the small and the large intestines. The term "vermiform" comes from Latin and means "worm-shaped". The appendix was once considered a vestigial organ, but this view has changed since the early 2000s.
This is important as it indicates that a complete colonoscopy has been performed. The ileocecal valve is typically located on the last fold before entry into the cecum and can be located from the direction of curvature of the appendiceal orifice, in what is known as the bow and arrow sign. [4]
McBurney's point is located one third of the distance from the right anterior superior iliac spine to the umbilicus (navel). [1] [2] This point roughly corresponds to the most common location of the base of the appendix, where it is attached to the cecum. [3] Normal location of the appendix relative to other organs of the digestive system ...
Colonscopy image of the cecum showing a bow and arrow sign. The appendiceal orifice, depicted, curves like a bow to show the location of the ileocecal valve on the most distal cecal fold. The bow and arrow sign is an endoscopic sign for determining the location of the ileocecal valve during colonoscopy.
