SUBCLAVIAN, AND ITS BRANCHES. 219 



muscles on the back of the fore arm. Some of its branches 

 reach the wrist, and anastomose with the carpal arteries. 



3. The ulnar artery, in its descent on the fore arm, sends off 

 many small and irregular muscular branches, called by Pro- 

 fessor Chaussier, Cubito-muscular: they do not require descrip- 

 tion. 



4. The Dorsalis Manus leaves the ulnar at the lower end of 

 the fore arm, and passes under the tendon of the flexor ulnaris 

 to the back of the hand. It there meets ramuscles of the radial 

 and interrosseous, and conjointly they supply with very small 

 branches the back of the wrist, of the metacarpus, and of the 

 fingers. 



5. As the Arcus Sublim's is about beginning, the ulnar arte- 

 ry sends superficial but small branches to the integuments of the 

 palm; and a little farther on, a considerable branch, which 

 dives into the bottom of the palm, through the muscles of the 

 little finger, and joins the ulnar extremity of the arcus profun- 

 dus: this is the Cubitalis Manus Profunda of Haller. 



6. The Arcus Sublimis then sends a branch to the ulnar side 

 of the little finger. Afterwards in succession three digital- 

 branches are sent off, which, arriving at the interstices between 

 the heads of their respective metacarpal bones, each divides 

 into two branches to supply the sides of the fingers which are 

 opposite to each other; one branch is called Digito-radial, the 

 other Digito-ulnar, according to the side of the finger on which 

 the artery may be placed. In this way the radial side of the 

 little finger, both sides of the ring finger, both sides of the mid- 

 die finger, and the ulnar side of the fore finger are supplied. 



The digital arteries, before they divide, receive each a small 

 branch from the arcus profundus. The digito-radial, and the 

 digito-ulnar arteries, pass along the sides of the fingers in front 

 to their extremities: at the joints and extremities, anastomoses 

 between the arteries of the two sides of the same finger fre- 

 quently occur. 



The arcus sublimis terminates on the radial side of the palm 

 by a branch which joins the inner branch of the Arteria Magna 

 Pollicis of the Radial
