Answer 1

The sciatic nerve is a major peripheral nerve that extends from the hind limb to the upper posterior leg. Sciatica is a painful condition caused by inflammation or compression of the sciatic nerve.

Step-by-step explanation:

The sciatic nerve is a major peripheral nerve of the hind limb that courses caudal to the femur. It is a combination of the tibial and fibular nerves and extends across the hip joint and gluteal region into the upper posterior leg. Sciatica is a painful condition resulting from inflammation or compression of the sciatic nerve or any of the spinal nerves that contribute to it.
