Answer 1

The sciatic nerve is not an epithelial structure.

Step-by-step explanation:

The sciatic nerve can be described as the largest nerve of the body. The sciatic nerve is formed when 5 nerves from the lower spine join. Hence, the sciatic nerve is not an epithelial structure. It is such long that it goes all the way from top of the leg till the foot. The sciatic nerve is involved in supplying sensations to the feet and to the skin.
