GENERAL HISTOLOGY

Detailed explanation-1: -appendix, formally vermiform appendix, in anatomy, a vestigial hollow tube that is closed at one end and is attached at the other end to the cecum, a pouchlike beginning of the large intestine into which the small intestine empties its contents. It is not clear whether the appendix serves any useful purpose in humans.

Detailed explanation-2: -Several biologists support the theory that the appendix is a vestigial organ that was once used by our herbivorous ancestors. It was found that in herbivorous vertebrates, the appendix is comparatively larger and it helped in the digestion of tough herbivorous food such as the bark of a tree.

Detailed explanation-3: -The human appendix may be considered as a vestigial organ as it has been proved that the removal of the organ after infancy does not create any harm [1-3]. But the appendix has developed to the extreme in human and strategically placed to an important site at the junction of midgut and hindgut.

Detailed explanation-4: -Vermiform appendix is a part of the digestive tract which lies in right lower quadrant of abdomen. It has a worm-like structure and arises during embryological life from the posteromedial wall of the cecum, about 2 cm below the ileocecal valve [1].
