i dont know yet

Explanation:

• The brachial plexus is a network of nerves formed by the anterior rami of the lower four cervical nerves (C5 - C8) and the first thoracic nerve (T1).
• It gives rise to nerves that innervate the pectoral girdle (such as the subscapular nerves) and the upper limbs (such as the axillary nerve, radial nerve, median nerve, and ulnar nerve).
• The lumbar plexus innervates the anterior and lateral abdominal wall, external genitals, and part of the lower limbs.
• The sacral plexus innervates the buttocks, perineum, and most of the lower limbs.
• The cervical plexus innervates the muscles of the neck and the skin of the head, neck, and upper chest.

Answer:

brachial plexus
