Show 364 PROF. K. VON BARDELEBEN ON THE [Apr. 17, The pcdmaris longus is large, it ends in the fascia pcdmaris. There is only one flexor digitorum, which gets an accessory belly from the ulna. From the very large Pp. arises a strong muscle which goes to the pollex. From the deep layer of the wrist comes a muscle which is inserted into the Pp. and the pollex. It m ay be cailedflexorpollicis et prcepollicis brevis, or, as it is also a " little adductor," perhaps " opponens poll, et prcepollicis." e. CARNIVORA. 1. LINSANG GRACILIS. (Plate XXI. fig. 5.) (Viverra, Prionodon.) a. Flexores. There are two palmares longi and two ulnares interni. The palmaris longus radialis is supplied by the n. medianus; the pcdmaris longus ulnaris by the n. idnaris; both ulnares interni (radialis, ulnaris) being supplied by the latter nerve. The palm. long. rad. arises with the m. ulnaris int. uln. from the internal condyle of the humerus, and ends in the volar pads and in digits 2-5, also between them in the webs. The palm. long. uln. arises with the former muscle and goes to both the radial and ulnar pads on the wrist, mainly to the ulnar one. The ulnaris int. rad. (humeralis) takes origin from the internal condyle of the humerus, while the ulnaris int. ulnaris s. proprius comes from the ulna ; both are inserted together into the pisiform. In this animal can be observed the fissure of main tendons and the coalescence of its delicate parts, and the development of a fascia or aponeurosis from tendons. Muscles on the wrist:- Connected f (1) An almost transverse muscle, like the pcdmaris with each < brevis of M a n , ending in the ulnar pad. other. [ (2) A n oblique muscle, ending in the thumb. (3) A muscle representing the greatest part of the " lig." carpi transversum of M a n ; this " ligament" consisting partly of the tendon of the palmaris longus ulnaris, for the greater part of muscular fibres. The flexor digitorum sublimis sends four tendons to the second phalanx of digits 2-5 ; the tendons are very weak, they are not so distinctly divided in two parts as in M a n ; a strong tendon joins the profundus and continues mostly into the 2nd and 3rd digits. The flexor digitorum profundus forms a fibrous mass near the wrist; from this mass arise five strong tendons for digits 1-5. |
