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 ...
Hepatic caecum or hepatic cecum is a name used in describing various physiological structures in some crustaceans, insects and lancelets. "Hepatic" refers to the liver , and the hepatic caecum may perform some functions that are analogous to the functions of the liver in vertebrates (except for lancelets , whose "proto-liver" is homologous).
The ileocecal fold (or ileocaecal fold) is an anatomical structure of the human abdomen formed by a layer of peritoneum between the ileum and cecum.The upper border of the ileocecal fold is fixed to the ileum opposite its mesenteric attachment, and the lower border passes over the ileocecal junction to join the mesentery of the appendix (and sometimes the appendix itself as well).
This structure consists of connective tissue covered by a simple squamous epithelium, called the mesothelium, which reduces frictional forces during digestive movements. The intraperitoneal regions include most of the stomach, first part of the duodenum, all of the small intestine, caecum and appendix, transverse colon, sigmoid colon and rectum ...
The appendix (pl.: appendices or appendixes; also vermiform appendix; cecal (or caecal, cæcal) appendix; vermix; or vermiform process) is a finger-like, blind-ended tube connected to the cecum, from which it develops in the embryo.
The histology of the ileocecal valve shows an abrupt change from a villous mucosa pattern of the ileum to a more colonic mucosa. A thickening of the muscularis mucosa, [citation needed] which is the smooth muscle tissue found beneath the mucosal layer of the digestive tract.
The function of taste perception is vital to help prevent harmful or rotten foods from being consumed. There are also taste buds on the epiglottis and upper part of the esophagus . The taste buds are innervated by a branch of the facial nerve the chorda tympani , and the glossopharyngeal nerve .
Ileum, caecum and colon of rabbit, showing Appendix vermiformis on fully functional caecum The human vermiform appendix on the vestigial caecum. The appendix was once believed to be a vestige of a redundant organ that in ancestral species had digestive functions, much as it still does in extant species in which intestinal flora hydrolyze cellulose and similar indigestible plant materials.
