The origin attachments are on, or near, the medial epicondyle of the humerus.

it is basically all the muscles in your forearm
These muscles can be divided into flexor-pronator and extensor-supinator groups. Forearm Pronation: 1. Pronator Teres 2. Pronator Quadratus Forearm Supination 1. Biceps Brachii 2. Supinator
Pronator quadrants flexor digitorum profundus flexor digitorum superficial is flexor carpi radials
The median nerve supplies most of the flexor muscles of the human forearm, and some hand muscles. The ulnar nerve also supplies two flexor muscles, and most of the remaining hand muscles that the median nerve does not cover.
The flexor digitorum profundus is a muscle in the forearm that flexes the fingers and holds the handle.The flexor carpi radialis and extensor carpi radialis longus allow you 'bend' the wrist as you turn the handle.
Flexor Muscles
Flexor digiti minimi brevis is a muscle that flexes the little finger. Frontalis is a facial muscle that wrinkles the eyebrow. FLexor pollicis brevis is a muscle that flexes the thumb.
this muscle is one among the 7 superficial extensor muscles of the postertor compartment of the forearm. this is otherwise known as the supinator longus. functionally it is a flexor of the elbow but it is grouped under extensor muscles. this muscle forms a fleshy bulk along the lateral border of the forearm. it forms the latersl boundary of cubital fossa. supplied by radial nerve. it acts as the flexor of the elbow joint.
Function: flexion and radial deviation of the wrist, along with other muscles which flex the wrist and radially deviate the wrist, weak pronation of the forearm along with other muscles which pronate the forearm and weak flexion of the elbow along with other muscles which flex the elbow
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
Muscles of the wrists include carpal muscles and extrinsic hand muscles.
