SURGICAL ANATOMY. 377 



The transversalis colli, suprascapular, and external jugular 

 veins ; 



The descending branches of the superficial cervical plexus, 

 and the brachial plexus of nerves; 



Lymphatic nerves and vessels. 



Triangle in Front of the Elbow-joint. 



Bounded 



Externally, by supinator longus; 



Internally, by pronator radii teres ; 



Base, above, by a line (imaginary) down through the con- 

 dyles ; 



Apex, below, by crossing of supinator longus and pronator 

 radii teres. 



It is covered in by skin, superficial fascia, and bicipital 

 fascia; the floor is formed by oblique fibres of the supinator 

 brevis and lower part of brachialis anticus muscles. 



It contains: 



From within outward, median nerve, brachial artery, and 

 venae comites, biceps tendon, and musculo-spiral nerve. 



Scar pa's Triangle 



is a large triangular space situated in the upper part of the 

 anterior surface of the thigh, through which the femoral vessels 

 descend. It is bounded 



Externally by sartorius, internally by adductor longus, above 

 by Poupart's ligament; below, apex is formed by crossing of 

 bounding muscles. 



It is covered in by*skin, superficial fascia lata, and cribri- 

 form fascia, and its floor is formed by the following from with- 

 out inward: iliacus, psoas, pectineus, and portion of adductor 

 brevis muscles. 



It contains: 



The femoral artery (with its profunda and cutaneous 

 branches), inclosed in the femoral sheath, femoral vein (joined 

 by profunda and long saphenous veins), anterior crural nerve and 

 its branches [from within outward being vein, artery, and nerve], 

 deep lymphatic glands and vessels, and adipose tissue. 



Axilla. 



This is a pyramidal space between the upper and lateral 

 part of the chest and the inner side of the arm. It is bounded 



In front, by the pectoralis major and minor muscles; be- 

 hind, by latissimus dorsi, teres major, and subscapularis ; in-
