palmar arch" with superficialis volae. Ante'rior ulna'ris recnr'rens, 

 just below elbow-jointup and inwards between brachialis 

 anticus and pronator radii teres, supplying these ; anas. 

 anastomotica magna, and inferior profunda. Po:te'rlOP fclns/riS 

 70Cur'rea3, just below preceding back and inwards beneath 

 flexor sublimis up to internal condyle humerus, supplying 

 joint and neighboring muscles; anas, inferior profunda, 

 anastomotica magna, interosseous recurrent. IntWOS'sea, short 

 trunk below tuberosity radius backwards to interosseous 

 membrane, dividing into: INTEKOS'SEA ANTE'RIOR, passing 

 down forearm on interosseous membrane, piercing membrane 

 at superior border pronator quadratus to descend to back of 

 wrist, supplying nutrient (to radial and ulnar arteries) and 

 muscular branches ; gives off median branch, accompanied 

 by do nerve. Anas, posterior carpal of radial and ulnar. 

 INTEROS'SEA POSTE'RIOR, down back forearm, between deep 

 and superficial muscular layers, to wrist, supplying these 

 muscles; anas, as preceding. Posterior interos'sea recur*rens t 

 near its origin to interval between olecranon and external 

 eondyle, beneath supinator bre vis ; anas, superior profunda, 

 posterior ulnar recurrent. HuBCUla'reB, to muscles of ulnar side 

 of forearm. Carpa'liS ante'liflP, beneath flexor profundus, anas. 

 anterior carpal of radial. Posterior Carpa'liS, above pisiform 

 tone, beneath flexor carpi ulnaris, giving small branch to in- 

 sculate with posterior carpal of radial, forming "posterior 

 carpal arch " ; continued along 5th metacarpus, forming its 

 dorsal branch. Commu'niCttll, from commencement palmar arch, 

 deeply inwards, anas, with radial forming "deep palmar 

 arch.'* Digita'loi, (4) from convexity of superficial palmar 

 arch, supplying ulnar side 4th and adjoining sides 3d, ad and 

 xst fingers.

 VEINS. 



Ulna'ris ante'riOf, from anterior carpus and ulnar side hand, 

 up along ulnar side forearm to elbow-joint, to form basilica 

 Communicates with median and posterior ulnar. 



Ulna'rs posto'rlor, pesterior ulnar border hand and vein of 

 little finger (v.salvatel'la) units* with preceding just below 

 elbow-joint. 



Basll'ica, coalescence of anterior and posterior ulnares; 

 receives median-basilic at elbow, ascends inner side arm to 

 vense comites of brachial artery, or axillary vein. 



Eai'a/lis, dorsum thumb, radial side index and hand at 

 bend elbow receives median-cephalic to become the cephalic.
