THE LIGAMENTS. 119 



140. Connection of the toes, Artie, digitorum pedis. 



a. Of the metatarsal bones with the toes, by ball articulation ; 

 b. Of "the phalanges with each other, by Ginglymus. On the 

 first phalanx of the great toe a double pulley with ossa sesa- 

 moidea. 



1. Lig. capsularia, very thick, cartilaginous in the sole, where is a groove 

 for mm. flexores, very thin on dorsum, strengthened by tendons of extensor 

 muscles, beneath which is a loose synovial capsule. 



2. Ligg. lateralia, very strong, from the capsular ligaments obliquely to the 

 tubercula behind the head of the oss. metatarsi, and ossa sesamoidea, and the 

 Phalanges. 



Movements : Flexion limited by the lateral ligaments and ex- 

 tensor tendons. Extension restrained by the inferior portion of 

 the capsular ligament. Both these more marked than abduction 

 and adduction which, moreover, only occur between the meta- 

 tarsal bones and first phalanges. The great toe is far less move- 

 able than the thumb.
