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. [10]
The human appendix averages 9 cm (3.5 in) in length, ranging from 5 to 35 cm (2.0 to 13.8 in). The diameter of the appendix is 6 mm (0.24 in), and more than 6 mm (0.24 in) is considered a thickened or inflamed appendix.
While the Vermes is no longer a taxonomic group, anatomists continue to use the description "vermiform" of animals or organs that are worm-shaped. The word root is Latin, vermes (worms) and formes (shaped). [3] A well known example is the vermiform appendix, a small, blind section of the gut in humans and a number of other mammals. [4]
Appendicitis is odd because the appendix doesn’t have a purpose, but a blockage in the lining of the appendix can result in infection and multiply. Stomach pain isn't the only symptom of ...
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]
Appendicitis is the most common emergent general surgery related problem to arise during pregnancy. There is a natural elevation in white blood cell count in addition to anatomical changes of the appendix that occur during pregnancy. [14] These findings, in addition to non-specific abdominal symptoms make appendicitis difficult to diagnose.
The cerebellar vermis (from Latin vermis, "worm") is located in the medial, cortico-nuclear zone of the cerebellum, which is in the posterior fossa of the cranium.The primary fissure in the vermis curves ventrolaterally to the superior surface of the cerebellum, dividing it into anterior and posterior lobes.
The pinworm (species Enterobius vermicularis), also known as threadworm (in the United Kingdom, Australia and New Zealand) or seatworm, is a parasitic worm.It is a nematode (roundworm) and a common intestinal parasite or helminth, especially in humans. [7]
