y. This branch of the gastrocnemius arises from the condyloid pit 

 of the femur, by a beautiful round cord-like tendon. 



1. This arises from the whole inner side of the head of the tibia, 

 and from the side of the patella.

Takes its origin from the anterior edge of the fibula, from the outer 

 side of the tubercle of the tibia, from the whole outer surface of the 

 ligamentum patellae, and from the fascia covering the tibialis anticus. 

 Its insertion is double ; by a broad tendon into the ligamentum caleis, 

 which acts as a patella to the heel, and by a narrower tendon, which, 

 at six inches below the first insertion, is inserted into the outer side of 

 the tendon of the first flexor perforatus digiti medii.

Arises from the back of the inner cartilage of the knee joint, and is in- 

 serted into the inner side of the ligamentum calcis, or patella of the 

 heel. 



tr. B. — -The tendon of this little muscle receives a large portion of 

 the semitendinosus. 



4. M. flexor perforatus primus digiti medii, . 1*8 \ 2*45 oz 



,, 3-1 J 



Arises by two heads, from the patellar fascia covering the outer con- 

 dyle, and by a long tendon, terminating in the condyloid pit ; and is 

 inserted by a perforated tendon on both sides of the distal ends of the 

 first phalanx of the middle toe. 



The tendon of this muscle is united by means of a cross slip (in- 

 tended to produce unity of action) with that of the next muscle, at a 

 point opposite the metatarso-phalangeal articulation. 



5. M. flexor perforatus secundus digiti medii, 1*3 1 1-45 oz 



1-6 J* * 0Z * 



Arises from the outer side of the ligamentum patellae, overlying the 

 tendon of vastus externus (2) ; and is inserted by a perforated tendon 

 into both sides of the distal end of the second phalanx of the middle 

 toe. 



6. M. flexor perforatus digiti externi, . . 1*3 J 1-45 oz 



Arises, by a double head, from the external ligament of the knee joint, 

 underlying the tendon of vastus externus (2), and from the condyloid 

 pit ; and is inserted by a perforate tendon into both sides of the distal 

 end of the first phalanx of the outer toe. 



B. — The tendon of this muscle, before it reaches the heel, passes 

 through the tendon of the second perforate tendon of the middle toe, 

 for a distance of three inches, as if in a sheath.
