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.
Appendicitis symptoms fall into two categories, typical and atypical. [37] Typical appendicitis is characterized by a migratory right iliac fossa pain associated with nausea, and anorexia, which can occur with or without vomiting and localized muscle stiffness/ generalized guarding. [37]
Appendix cancer, also known as appendiceal cancer, is a very rare malignant tumor that forms in the vermiform appendix. [7] Gastrointestinal stromal tumors are rare tumors with malignant potential. [8] Primary lymphomas can occur in the appendix. Breast cancer, colon cancer, and tumors of the female genital tract may metastasize to the appendix ...
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 ...
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.
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.

The appendix is commonly located in the retrocecal or pelvic region. The obturator sign indicates the presence of an inflamed pelvic appendix. Evidence shows that the obturator test does not adequately diagnose appendicitis, but can be used in conjunction with other signs and symptoms to make a diagnosis.
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]
