b) Upper limb
c) Abdomen
d) Head and neck

Answer 1

The sacral plexus provides the entire nerve supply for the lower limb, which includes the sciatic nerve, tibial nerve, and fibular nerve.

Step-by-step explanation:

The sacral plexus is the nerve plexus that provides the entire nerve supply for the lower limb. Specifically, it is associated with the lower lumbar and sacral spinal nerves, which includes nerves such as the sciatic nerve, a combination of the tibial nerve and the fibular nerve. The sciatic nerve extends across the hip joint, running through the gluteal region into the upper posterior leg and is responsible for much of the nervous control and sensation of the lower limb.
