forearm

It forms the lateral border of the cubital fossa

It arises from the coronoid process and lateral epicondyle.

The Median nerve passes deep to both heads

It is the most lateral of the superficial flexors of the forearm

It passes anterior to the lateral epicondyle of the humerus

Sensory loss from injury to the superficial radial nerve will usually result in loss of sensation over the entire thumb

It is the larger terminal branch of the posterior cord of the brachial plexus

Injury to the radial nerve from fracture of the shaft of the humerus will result in wrist drop

The radial artery is the larger of the terminal branches of the brachial artery

The radial artery runs under brachialis as it leaves the cubital fossa

The radial artery has just one named branch proximal to the carpal braches

The radial artery has no involvement in the elbow anastomotic network

Supplies flexor carpi ulnaris and half of flexor digitorum profundis

Gives rise to most of its braches in the upper arm

May be compressed between the two heads of pronator teres

Enters cubital fossa lateral to the brachial artery
