Cecum Anatomy

The cecum is the most proximal part of the large intestine and is located between the ileum distal small bowel and the ascending colon. The word cecum stems from the latin caecus meaning blind.

Digestive System Structure Of The Digestive System

It is typically located on the right side of the body.

Cecum anatomy. Having served as a site for cellulose digestion in our ancestors the cecum now simply acts as a reservoir for chyme which it receives from the ileum. While the cecum is usually intraperitonea. The cecum the first part of the large intestine is a sac with a closed end that occupies the right iliac fossa the hollow of the inner side of the ilium the upper part of the hipbone.

The mucosal layer forms the innermost layer of the cecum comprising of mucous membrane containing various goblet cells. The goblet cells are responsible for releasing mucus which helps in lubricating the cecum walls. It is also separated from the colon by the cecocolic junction.

Muscularis strongly pronounced inner circular musculature outer longitudinal musculature almost. Lymph from both the appendix and cecum drain into the ileocolic lymph nodes. Mucosa columnar epithelium with crypts contains goblet and endocrine cells.

Submucosa with blood vessels and lymph nodes. The cecum is supplied by the ileocolic artery which is a terminal branch of the superior mesenteric artery. It receives chyme from the ileum and connects to the ascending colon of the large intestine.

The cecum comprises of four different layers of tissue all having distinct functions. The microscopic structure of the cecum is equal to that of the colon. Histology and anatomy of the cecum.

It is separated from the ileum by the ileocecal valve or bauhins valve. Guarding the opening of the ileum the terminal portion. The cecum or caecum is a pouch within the peritoneum that is considered to be the beginning of the large intestine.

The ileocolic artery gives rise to the appendicular artery to supply the appendix.
