antebrachium
superficial fascia of the upper limb
contains fat, superficial veins, and cutaneous nerves
cephalic vein
runs in the deltopectoral triangle
then along the anterolateral surface of the bicep
the anterolateral surface of the forearm and wraps around onto the posterior surface where it continues into the posterior surface of the hand
basilic vein
emerges from the deep fascia halfway down the anteromedial surface of the biceps
continues along the anteromedial surface into the forearm and then dives around to the posterior surface where it continues into the dorsal surface of the palm
median cubital vein
joins the cephalic and basilic veins across the cubital fossa
cephalic vein
passes deeply through the deltopectoral triangle to join the axillary vein
perforating veins
penetrate the deep fascia and connect superficial veins to deep veins

lateral cutaneous nerve of the forearm
located at the level of the elbow in the superficial fascia lateral to the biceps brachii tendon
close relationship to the cephalic vein and the median cubital vein
medial cutaneous nerve of the forearm
located on the medial side of the biceps brachii tendon
close relatinoship to the basilic vein
superficial branch of radial nerve
located in the superficial fascia near the styloid process of the radius
dorsal branch of ulnar nerve
located in superficial fascia near the styloiid process of the ulna
deep fascia
extends from the shoulder to the fingertips
attaches to the bones of the upper limb and forms compartments that contain groups of muscles
