humerus and the ulna and is inserted into the pisiform and the 

 fifth metacarpal bone. 



The extensor die/it. long, (radial is tubl. '?) goes to digits 3-5. 



The " extensor dig. minimi propriv.s" ends by three tendons on 

 digits 3-5 (1st phalanx). 



The ext. indicis et pollicis comes from the distal end of the ulna.

The " palmaris longus" arises (very broad) from the internal 

 condyle (ham.) and ends by four tendons (connected with each 

 other) on digits 2-5, some fibres going to the Pp. and to the 

 neighbourhood of the Pm. 



As this muscle has two nerves (from the medianus and the 

 ulnaris) it may perhaps be considered as formed by union of two 

 palmares. 



On the wrist there are four little muscles : — 



^(1) Prom the pisiform and the tendon of the idnaris 



internus to the ulnar border of the manus. 

 (2) Prom the pisiform : ( continue into one tendon, 

 J which ends on the sheath

[ fifth digit. 



X. medianus : (4) Prom the Pp to the thumb. 

 Underlying these four muscles there is a strong transverse 

 ligament.

 I which are cleft and perforated by the following

and ulnaris. j The flexor dig. prof, has very strong and broad 

 tendons, which are connected with those of 

 the perforatum where they pass it. 



The radial part of the profundus goes to the pollex and index.

There are strong nerves and vessels running to the Ph. 



The gastrocnemius consists of two separate muscles arising from 

 the inner and the outer condyle of the femur, joining each other 

 only on the insertion on the calcaneum. 



The pjlantaris takes origin in common with the lateral gastro- 

 cnemius, runs down, crossing the tibial or inner gastrocnemius at an 

 acute angle ; it is fixed on the calcaneum and ends in the " fascia " 

 plantaris, the tendinous fibres going mostly to the Ph.
