2. the extended nose of the elephant, containing many muscles giving it extraordinary strength and mobility. Anatomically it includes the nose and upper lip. There is a single finger-like papilla on the dorsal part of the tip in the Asian elephant and two papillae on the African elephant.

RESULTS: ORIGIN: In one, out of 59 limbs, abnormal origin of subclavian artery was encountered, where the right subclavian artery instead of brachiocephalic trunk emanated directly from arch of aorta distal to origin of left subclavian artery and coursed towards right, first horizontally behind the oesophagus and then vertically upwards to reach its normal position.
DISCUSSION: According to standard textbooks of anatomy, the right subclavian artery originates from the brachiocephalic trunk and the left from the arch of aorta.
It may be attributed to the fact that on the left side, it arises from the arch of aorta situated at a lower level while on right side, it arises from brachiocephalic trunk situated at a higher level, and thus the left subclavian artery has to run a longer distance than its counterpart to reach its destination.
