Accepted Answer

The sciatic nerve is the main branch of the sacral plexus, which is located in the pelvic region. It is the largest nerve in the body and runs from the lower back down through the legs, providing both motor and sensory function to the lower limbs. It is not the smallest nerve in the body, it is not part of the brachial plexus, and it is not cranial nerve II.
