the front of the joint ; the posterior large, and passes backwards, 

 supplying the joint' and deltoid muscle. 



BRACHIAL. 



The brachial artery extends from the axillary to the elbow joint, 

 descending upon the inner edge of the biceps flexor muscle, in com- 

 pany with the median nerve. (Fig. 120.) 



Profunda major, '^^ arises from the brachial at its upper part, and 

 passing between two heads of the triceps muscle, with the spiral 

 nerve, supplies the external portion of the arm. 



Profunda minor,^^ is small, arises below the last, is distributed 

 superficially about the internal condyle, and anastomoses with the 

 radial recurrent.^^ 



Nutritious artery, arises opposite the nutritious foramen of the hu- 

 merus, which it enters to supply the bone. 



Anastomotic,'^'^ arises from the bra- Fig. 121. 



chial just above the elbow, and winding 

 round the internal condyle, anastomo- 

 ses with the ulnar recurrent. 



The brachial passing under that por- 

 tion of the brachial fascia which is con- 

 nected with the tendon of the biceps, 

 now usually divides into the radial and 

 ulnar, although this division may take 

 place at any point between the arm-pit 

 and elbow. 



RADIAL. 



The radial'^ is more superficial than 

 the ulnar. It descends the outer side 

 ofthearm,**^ between the tendons of the 

 supinator radii longus and flexor carpii 

 radialis. 



Radial recurrent,'^^ arises from the 

 radial and inosculates with the profunda 

 major. In its descent, the radial gives 

 off numerous muscular branches, until 

 it reaches the wrist, it then passes back- 

 wards under the extensor tendons of the 

 thumb. 



Superjicialis voice, is given off from 

 the radial, and distributed upon the pal- 

 mar surface of the thumb, joining the 

 superficial arch.
