172 PRACTICAL ANATOMY. 



The cubital fossa has geometrically a 



1. Roof, formed by the skin and fasciae superficial and deep. 



2. Floor, formed by the brachialis anticus and supinator brevis. 



3. Superior border, formed by an imaginary line from condyle to condyle. 



4. Outer border, formed by the brachio-radialis muscle. 



5. Inner border farmed the pronator radii teres muscle.

The fossa contains the following structures 



(i) The brachial artery and veins ; (2) the radial artery ; (3) the ulnar artery ; 

 (4) the tendon of the biceps muscle ; (5) the median nerve ; (6) the musculo- 

 spiral nerve ; (7) the radial recurrent artery ; (8) the ulnar recurrent artery 

 (9) the common interosseous artery. 



The radial groove has these geometrical parts :
