Brachial plexus....
The brachial plexus supplies motor and sensory innervation to the upper limb. It is formed by the ventral rami of the spinal nerves C5-T1, and its branches include the musculocutaneous, median, ulnar, radial, and axillary nerves. These nerves control the muscles and provide sensation to the shoulder, arm, forearm, and hand.
Subclavian artey becomes axillary artery. Axillary artery becomes brachial artery. Brachial artery divides into radial and ulnar branches. You palpate radial artery at distal end of radius bone. So you feel a pulse betwwen radius and your fingers. So it is better felt than ulnar artery.
This fossa is an important clinical area because it contains the biceps tendon, the brachial artery and its terminal branches (radial and ulnar arteries), the brachial veins, and part of the median and radial nerves.it contains the biceps tendon, the brachial artery and its terminal branches (radial and ulnar arteries), the brachial veins, and part of the median and radial nerves.
The main nerve related to the sense of touch is the somatosensory nerve, which includes sensory nerves such as the median, ulnar, radial, and the dermatomes of the spinal nerves. These nerves transmit touch signals from the skin to the brain for processing.

The vessel after the axillary artery, before it branches into the radial artery and ulnar artery is called the brachial artery.
The radial and ulnar arteries branch off from the brachial (axillary) artery below the elbow.
The nerves issuing from the Brachial plexus in order from anterior to posterior are musculocutaneous nerve, median nerve, ulnar nerve, radial nerve, and axillary nerve.

The brachial artery is the continuation of the axillary artery. At the elbow it then divides into the radial and ulnar arteries.
The deep veins that drain the forearm are the radial veins and ulnar veins. These veins run alongside the radial and ulnar arteries respectively, and eventually join to form the brachial veins. The brachial veins then merge to form the axillary vein, which continues the drainage pathway.
Axillary nerve- supplies the deltoid and teres minor muscles and the skin of the shoulderRadial nerve- controls the extensor muscles of the upper limb as well as the skin over the posterior and lateral margins of the armMusculocutaneous nerve- supplies the flexor muscles of the upper limb to the skin of the lateral armMedian nerve- innervates the flexor muscles of the forearm and digits, the pronator muscles, and the lateral skin of the hand.Ulnar nerve- controls the flexor carpi ulnaris muscle of the forearm, other muscles of the hand, and the medial skin of the hand

You have three nerves, which supply your forearm. Radial, ulnar and median nerve. Out of these three nerves, median nerve is the main nerve to supply forearm muscles and some of the hand muscles.
Ulnar and Radial
This group of nerves innervates the muscles and skin of the entire upper limbs except the Trapezius muscle and the skin near the axilla (arm pit). The plexus comes off the spinal cord at C4,C5,C6,C7,C8 and T1 where they mix and form a plexus. There are 5 main nerves that are formed: Musculocutaneous, axillary, radial, median and ulnar nerves.
