1, Superior sesamoid or suspensory ligament, giving off a band, 2, to the extensor pedis. 3, Lateral 

 sesamoid ligament. 4, Superficial inferior sesamoid ligament. 5, Deep sesamoid ligament. 6, Crucial 

 ligament. 7, Lateral ligament of the coronet -joint. 8, Posterior interphalangial ligament. 9, Inter- 

 sesamoidal substance over which the tendons pass. 10, Sesamoid bones. 11, Ligamentous substance common 

 to the coronal and navicular bones. 12, Navicular bone. 13, Intersesamoid ligament. 14, Lateral 

 navicular ligament. 15, Anterior lateral ligament of the coffin-joint. 



from the anterior border of the navicular bone to the under surface of 

 the os pedis or foot-bone; b, the lateral navicular ligaments which proceed 

 from each extremity of the navicular bone (l) to the wing of the foot-bone, 

 (2) to the inner surface of the lateral cartilage, and (3) to the side of the 

 coronet-bone. 



The movements of the coffin-joint are flexion and extension. 



COXO-FEMORAL ARTICULATION OR HIP-JOINT 



The hip-joint is formed by the union of the head of the femur or 

 thigh-bone with the cotyloid cavity of the coxa (fig. 358). 



Four ligaments are engaged in connecting the two bones, viz. the 

 capsular, cotyloid, round, and pubio-femoral. 



The Capsular Ligament is attached around the articular margin of 

 the femur, to the margin of the cotyloid cavity, and to the cotyloid 

 ligament. Its inner surface is lined by a synovial membrane.
