What are the muscles of the forearm and hand?
FOREARM AND HAND: Wrist Flexor Group These muscles are the flexor carpi radialis, palmaris longus, and flexor carpi ulnaris. All three muscles of the wrist flexor group are superficial in the anterior forearm.
What is the dorsal forearm?
The dorsal compartment of the forearm contains nine muscles: four belong to the superficial group (extensor digitorum communis, extensor digiti minimi, extensor carpi ulnaris and anconeus) and five to the deep group (supinator, abductor longus, extensor pollicis brevis, extensor pollicis longus, and extensor indices).
What is the dorsal area of the hand?
The opposite side of your hand, the back of your hand, is called the dorsal aspect of the hand. The term ‘dorsal’ refers to something that is towards the back of something. In this case, it’s the back of our hand.
What is the muscle on your forearm called?
The superficial compartment of the flexor surface of the forearm contains the pronator teres, the flexor carpi radialis longus, the palmaris longus, the flexor carpi ulnaris, and the flexor digitorum superficialis. All of these muscles originate primarily from the medial epicondyle of the humerus.
What are the muscles in your hand called?

What are the flexor muscles?

What is the anatomy of a hand?
The human hand has 27 bones: the carpals or wrist accounts for 8; the metacarpals or palm contains five; the remaining fourteen are digital bones; fingers and thumb. The palm has five bones known as metacarpal bones, one to each of the 5 digits. These metacarpals have a head, a shaft, and a base.
What are the layers of the hand?
Number 1 is the deep antebrachial fascia, 2 is the superficial fascia and dorsal venous network of the hand, 3 is the palmar aponeurosis, 4 is the thenar muscles, 5 is the hypothenar muscles, 6 is the palmaris brevis, 7 is the cephalic vein, and 8 is the basilic vein.
What are the arm muscles called?
biceps
The pectoralis major, latissimus dorsi, deltoid, and rotator cuff muscles connect to the humerus and move the arm. The muscles that move the forearm are located along the humerus, which include the triceps brachii, biceps brachii, brachialis, and brachioradialis.
What is the wrist muscle called?
The two important ones are flexor carpi radialis, and flexor carpi ulnaris. They both arise from the medial epicondyle, where they share a massive tendon of origin, the common flexor tendon, with two other flexor muscles.
