The plexus that travels through the axillary region is the

Brachial plexus

Explanation:

Brachial plexus is a plexus of nerves that travels through the axillary region.

It is formed by ventral rami of spinal nerves C5-T1.

Five ventral rami forms roots/trunks that separate into divisions that then form cords that give rise to branches. Mojor nerves include Axillay, radial, musculocutaneous, Ulnar, median.

In the axilla it is placed lateral to the 1st part of axillary artery, it surrounds the second part of axillary artery, one cord lying medial to it, one lateral to it, and one behind it, at the lower part of axilla it gives off its terminal branches to the upper limb.

Hence, The plexus that travels through the axillary region is the brachial plexus.

The correct answer is: brachial plexus.

Explanation:

The brachial plexus is a net that is made of cervical nerves (more specifically, by the anterior rami of C5, C6, C7, C8 and T1) and extends from the cervicoaxillary canal to the armpit.

The nerves that form from the brachial plexus are both motor and sensory fibers that will provide innervation to the chest, the shoulder, the arm, the forearm, and the hand.
