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 cecum is a pouch-like structure of the large intestine, located at the junction of the small and the large ...
Human vestigiality. The muscles connected to the ears of a human do not develop enough to have the same mobility allowed to monkeys. Arrows show the vestigial structure called Darwin's tubercle. In the context of human evolution, vestigiality involves those traits occurring in humans that have lost all or most of their original function through ...
Appendicitis is inflammation of the appendix. [ 2 ] Symptoms commonly include right lower abdominal pain, nausea, vomiting, and decreased appetite. [ 2 ] However, approximately 40% of people do not have these typical symptoms. [ 2 ] Severe complications of a ruptured appendix include widespread, painful inflammation of the inner lining of the ...
Vestigiality. In humans, the vermiform appendix is sometimes called a vestigial structure as it has lost much of its ancestral digestive function. Vestigiality is the retention, during the process of evolution, of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. [1]
The appendicular skeleton is the portion of the vertebrate endoskeleton consisting of the bones and cartilages that support the paired appendages (fins, flippers or limbs).In most terrestrial vertebrates (except snakes, legless lizards and caecillians), the appendicular skeleton and the associated skeletal muscles are the predominant locomotive structures.
The function of the appendix is uncertain, but some sources believe that it has a role in housing a sample of the gut microbiota, and is able to help to repopulate the colon with microbiota if depleted during the course of an immune reaction. The appendix has also been shown to have a high concentration of lymphatic cells.
Recovery time. 1-3 weeks. Frequency. Common. [edit on Wikidata] An appendectomy (American English) or appendicectomy (British English) is a surgical operation in which the vermiform appendix (a portion of the intestine) is removed. Appendectomy is normally performed as an urgent or emergency procedure to treat complicated acute appendicitis.
The abdominopelvic cavity is a body cavity that consists of the abdominal cavity and the pelvic cavity. [1] The upper portion is the abdominal cavity, and it contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, small intestine, and most of the large intestine. The lower portion is the pelvic cavity, and it contains the urinary ...
