2) brachial plexus
3) lumbar plexus
4) sacral plexus

Answer 1

The largest and longest nerve of the body, the sciatic nerve, is found in the sacral plexus.

Step-by-step explanation:

The largest and longest nerve of the body is found in the sacral plexus. This nerve plexus comes from the lower lumbar nerves L4 and L5 and the sacral nerves S1 to S4. The most significant nerve to arise from the sacral plexus is the sciatic nerve, which extends across the hip joint and is the longest and thickest nerve in the body.

It is known for being associated with sciatica, a condition resulting from the compression or irritation of this nerve.
