	eMedicine - Vermiform Appendix : Article by Steven L Lee, MD
		In 60% of patients, obstruction is caused by hyperplasia of the submucosal follicles.
		At this stage, bacterial invasion of the wall of the appendix occurs and is known as acute suppurative appendicitis.

		In human anatomy, the vermiform appendix (or just appendix) is a blind ended tube connected to the caecum.
		While the base of the appendix is at a fairly constant location, the location of the tip of the appendix can vary from being retrocaecal to being in the pelvis to being extraperitoneal.
		While most believe the appendix is a useless and purely vestigial organ, others suggest it may have a function in the lymphatic system.

		The appendix appears to be strategically placed and structurally composed of tissues which are vital in establishing and maintaining the various types of body defences or immunity necessary in recognition of such assaults and having a part to play in their repulsion.
		The appendix is thus one of the guardians of the internal environment of the body from the hostile external environment.
		He described the bloodless fold as part of the mesentery of the appendix, wrote on the positions or the appendix around the caecal apex according to a clock race, and also wrote on the types or caecum to which the appendix was attached.

		The appendix is a closed-ended, narrow tube up to several inches in length that attaches to the cecum (the first part of the colon) like a worm.
		(The anatomical name for the appendix, vermiform appendix, means worm-like appendage.) The inner lining of the appendix produces a small amount of mucus that flows through the open center of the appendix and into the cecum.
		The blockage may be due to a build-up of thick mucus within the appendix or to stool that enters the appendix from the cecum.

	Vermiform appendix Summary
		Despite the fact that the appendix is not essential to good health, appendicitis--an inflammation of the appendix--can be life threatening and usually requires surgery to remove the appendix.
		In human anatomy, the vermiform appendix (or appendix, pl. appendixes or appendices) is a blind ended tube connected to the cecum ('caecum' in British English).
		The longest appendix ever removed was that of a Pakistani man on June 11, 2003, at Pakistan Institute of Medical Sciences, Islamabad, Pakistan, measuring 23.5 cm (9.2 in) in length.

		The fact that inflammatory affections of the vermiform appendix give rise to a considerable number of the so-called pericaecal inflammations is now accepted in every part of the medical and surgical world...
		Whatever may be the position of the healthy appendix found in the dead-house and I am well aware that its position when uninflamed varies greatly I have found in all of my operations that it lay, either thickened, shortened, or adherent, very close to its point of attachment to the caecum.
		The mesentery of the appendix was carefully tied in sections, and the base of the appendix dislodged from an inverted pouch of caecum, ligated at its base, and cut away.

		Therefore, through the knowledge that the removal of the appendix might actually cause certain types of tumors, it is thus established that this structure cannot possibly be expendable.
		Another contribution of the appendix to the human anatomy is by its active participation in the lymphatic system.
		Hence, although it is not proven, the appendix might actually have the capacity to prevent a variety of deadly diseases by giving the body the protection it needs through the production of numerous antibodies that combat pathogens that enter the body via food consumption.

	The human vermiform appendix - Journal of Creation (TJ)
		The appendix appears to be strategically placed and structurally composed of tissues which are vital in establishing and maintaining the various types of body defences or immunity necessary in recognition of such assaults and having a part to play in their repulsion.
		The appendix is thus one of the guardians of the internal environment of the body from the hostile external environment.
		Thus whereas the choice of the adjective ‘vermiform’, meaning worm-like, is accurately descriptive of the organ, the choice of the noun ‘appendix’ from the beginning of the organ’s nomenclature, gave it little chance of ever being considered important.
