Question

The longest nerve of human body is
A. Sciatic nerve
B. Radial nerve
C. Median nerve
D. Ulnar nerve

Answer 1

Hint: Nerves present in the body are all of variable length and size. The size of the nerve depends on the location and function of the nerves.

Complete answer:
The longest nerve is sciatic nerve present in the lower regions of the body

Additional information:
- The sciatic nerve begins from the lower back, passes deep in the buttock and down the back of the thigh all the way to the heel and sole of the foot.
- It is formed by the union of 5 nerve roots from the lower spine.
- The sciatic nerve serves a vital role in connecting the spinal cord with the skin and muscles of the thigh, leg, and foot.
- In a condition called sciatica painful sensations radiate from your lower back and down your leg. This happens when the sciatic nerve is compressed or irritated.

Notes: The radial nerve is a nerve in the human body that supplies the posterior portion of the upper limb. The median nerve, colloquially known as the "eye of the hand," is one of the three major nerves of the forearm and hand and innervates the intrinsic muscles of the hand. The ulnar nerve is one of the three main nerves in your arm that travels from your neck down into your hand, and can be constricted in several places along the way, such as beneath the collarbone or at the wrist.
