Medial epicondyle of humerus to lateral surface of the radius.
Humeral head: medial supracondylar ridge of humerus (common flexor tendon)
ulnar head: coronoid process of ulna.
Middle of the lateral surface of the body of the radius.
Rotates arm medially; Pronation.
Pronation of forearm, flexes elbow.
Innervation – Nerve control
The pronator teres is innervated by the median nerve.
To stimulate the pronator teres, a signal begins in the precentral gyrus in the brain and goes down through the internal capsule. It continues down the corticospinal tracts through the capsule, midbrain, and pons where it arrives at the medullar pyramids. Once at the pyramids, the corticospinal tracts decussate and the signal goes down the lateral corticospinal tract until it reaches the ventral horns of C5, C6, C7, C8, and T1. The signal then goes through the ventral rami and down the root ganglion of C5, C6, C7, C8, and T1 (Brachial Plexus). Next, the signal goes down the median nerve branch of the Brachial Plexus and stimulates the Pronator Teres to contract causing the hand to pronate. Wiki
Ulnar artery and radial artery.
The ulnar artery is the main blood vessel, with oxygenated blood, of the medial aspect of the forearm. It arises from the brachial artery and terminates in the superficial palmar arch, which joins with the superficial branch of the radial artery. It is palpable on the anterior and medial aspect of the wrist. Wiki
In human anatomy, the radial artery is the main artery of the lateral aspect of the forearm.
