118 SPECIAL ANATOMY. 



and cakaneus, describing with the lig. cakan. navicul. sitperius a figure like the 

 capital letter Y ; after their division, the two rows of tarsal bones separate 

 from each other. 



3. Lig. cak.-cub. sitperius, thin, small, from Cakaneus to os cuboideum. 



Movements: Adduction and Abduction, whereby the sole of 

 the foot is turned inwards or outwards, arising by talus and 

 calcaneus on one, os naviculare and cuboideum on the other 

 side, assisted by slight lateral movement between talus and 

 calcaneus. 



136. Connection of the Metatarsal Bones, 



Jlrtic. metatarsi. 



These bones are united with those of the tarsus and with one 

 another by close articulations. 



137. A. With the tarsus. 1. The tarsal extremity angular, 

 with even articular surfaces. That of the third metatarsal bone 

 makes an angle, forwards, with the line of the rest. 



a. Os metatarsi I. 1. Lig. plantare, stronger than the Lig. dorsale, with 

 synovial capsule. 2. Aponeurosis of the tendon of m. peronaus long, to the 

 os (Mneiforme I. 3. Aponeurosis of the tendon of m. tibialis anticus to the Os 

 metatarsi I. 



b. Os metatars. II. 1. Lig. plantaria, two from the second cuneiform, the 

 third from first, cuneiform bone, lateral. 2. Lig. dorsalia, three; a., internum 

 from first cuneiform; #. externum from third cuneiform, thin; y. medium from 

 second cuneiform. 



c. Os metatars. III. 1 . Lig. dorsale from third cuneiform. 2. Lig. plantare, 

 very thin; instead, the tendon of m. peronaus long. 3. Lig. laterak extern, sen 

 interosseum. 



d. and e. Oss. metatars. IV. and V. 1. Lig. interossea, very strong. 2. 

 Lig. dorsale and lig. obliquum, on oss. metatars. V., very loose. Instead of Lig. 

 plantare, the tendon of the muscles peron. long, and tibial. posticus. 



138. B. The posterior extremities with each other. Ligg. 

 baseos ossium metatarsi. 



1. Ligg. dorsalia. 2. plantaria, stronger. Transverse from the one to the 

 other bone. 



3. Ligg. interossea, strong, short, and thick, between the rough, lateral sur- 

 faces, are wanting between the first and second os metatars. 



139. C. The anterior extremities. No articular surfaces, but 

 synovial capsules ; rather moveable on one another. 



1. Lig. transversum s. capitulorum oss. metatarsi, on the sole between the 

 heads, below the sheaths of the tendons of the flexor muscles; loose. 



Movement: indistinct. Os Metatars. I., of great toe, is not 

 more moveable than the rest.
