radial nerve |
- passes out of radial groove bw lateral head of triceps and brachialis. it then innervates brachioradialis and extensor carpi radialis longus - it then ends up in cubital fossa and divides into a superficial and deep radial nerve -superficial radial nerve- passes bw brachiradialis and pronator teres. goes under brachioradialis and becomes cutaneous to the back of the first web space -deep radial nerve- innervates supinator and then goes into posterior compartment of forearm

|
ulnar nerve |
- off medial cord - thru arm, innervating nothing - passes bw medial epicondyle and olecranon - innervates flexor carpi ulnaris'- sends a branch to innervate ulnar 1/2 of flexor digitorum profundus - proximal to wrist sends dorsal cutaneous branch to ulnar side of back of hand - proximal to wrist sends palmar cutaneous branch to ulnar side of palm of hand - crosses wrist and passes thru Guyon's canal bw pisiform and hook of hamate |
|
|
median nerve |
- passes into middle of the cubital fossa - under bicipital aponeurosis - between the 2 heads and innervates pronator teres - between the 2nd and 3rd layers of anterior forearm - innervates flexor carpi radialis, palmaris longus, and flexor digitorum superficialis - sends off one branch- anterior interosseus nerve , that innervates radial 1/2 of flexor digitorum profundus, flexor pollicis longus, and pronator quadratus - median nerve crosses wrist under tendon of palmaris longus - enteres into most superficial part of carpal tunnel

|
|
radial artery |
- off brachial artery - passes to radial side of forearm bw brachioradialis and pronator teres w the radial nerve - passes to the distal anterior surface of the radius (where u take ur pulse) - @ this point, it has one branch, the superficial palmar branch. it passes through the thenar compartment of the palm and passes to the dorsum of the hand |
|
|
ulnar artery |
off brachial artery - passes under the pronator teres and flexor digitorum superficialis - passes bw flexor digitorum superficialis and flexor digitorum profundus - @ this point, has 2 branches: 1. anterior interosseous artery - travels on anterior surface of interosseous membrane w the anterior interosseous nerve 2. posterior interosseous artery - passes thru interosseous membrane into posterior compartment
- ulnary artery continues distally in forearm and joints ulnar nerve about mid-forearm - proximal to wrist it will have one branch- dorsal carpal branch of the ulnar artery (which goes into the back of the hand) - ulnar artery passes into Guyon's canal w ulnar nerve - radial and ulnar artery combine in the hand |
