The Anterior Compartment of the forearm
This paper will discuss the anterior compartment into details and the nerves and arteries that innervations it. The anterior compartment composed of three layers namely: the superficial, the immediate and the deep layer. The superficial layer consists of four muscles i.e pronator teres, flexor carpi radialis, palmaris longus, and flexor carpi ulnaris. The immediate layer comprised of one muscle, the flexor digitorum superficial muscle. The deep layer consists of three muscles i.e flexor digitrum profundus, flexor pollicis longus, and pronator quadratus.
The superficial muscles: muscles in this compartment such as: flexor digitorum superficilis, flexor digitorum profundus, flexor pollicis longus and …show more content…
As I closely observed the cadaver, this muscle has two heads; the superficial head arising from the medial epicondyle of the humerus and the deep head arising from the ulna head. These two heads has parallel muscle fibers inserting directly onto the middle of the radius. It is innervated by the median nerve arising from the medial epiconedyle that passes between the two heads pronator teres. This nerve gets pinched between the two heads causing pronator teres syndrome. One of the symptoms is numbness in the fingers digit one, two, three and half of digit four. Along the median nerve lies the brachial artery which splits at the cubital fossa forming the ulnar and radial …show more content…
This muscle is innervated by the ulnar nerve which runs from posterior medial epicondyle into the forearm buried between the two origins of flexor carpi ulnaris; the medial epicondyle and the ulna bone. This nerve gets entrapped between the two origins of flexor carpi ulnaris causing numbness or pain in the elbow, wrist and fingers. Also running down the flexor carpi ulnaris, is the ulnar artery which branches from the brachial artery at the cubital fossa. The ulnar nerve runs alongside the ulnar artery which lies between the flexor digitorum superficialis and flexor digitorum profundus. The ulnar nerve then continues into the carpal bones where it passes the Guyon’s
