364 ZOOTOMY. 



the head of the fibula, united with the preceding : its tendon 

 passes with those of the other peronei into the foot, and is 

 inserted into the distal end of the last metatarsal. 



470. The interossei (i.o) have the same general disposition as those 

 of the manus (§ 430), there being a pair on the ventral or plantar side of 

 each metatarsal : there are also two very slender slips, one on the 

 post-axial side of the second (apparent first), another on the pre-axial 

 side of the fourth metatarsal. 



LV. Dissect away the origins and insertions of any 

 muscles still left attached to the hip and knee- 

 joints, and make out : 



471. The capsular ligament of the hip-joint, a mem- 

 brane attached on the one hand just external to the rim of 

 the acetabulum and on the other round the neck of the 

 femur : partly remove it so as to see the synovial cavity 

 which it helps to enclose. 



472. The ligamentum teres, exposed by the severance 

 of the capsular ligament : it is a strong band of fibres 

 passing from the bottom of the acetabulum to the pit on the 

 head of the femur (§ 93). 



473. Tlie cotyloid ligament, a rim of fibro-cartilage attached round 

 the edge of the acetabulum. 



474. The capsular ligament of the knee-joint, bound- 

 ing its synovial cavity, which will have been opened in 

 tracing the tendon of the extensor communis digitorum : it 

 is strengthened in front by the ligamentum patellae 

 already seen (§ 440), and at the sides by the internal and 

 external lateral ligaments, which pass respectively from 

 the inner and outer tuberosities of the femur to the cor- 

 responding tuberosities of the tibia. 



475. The inter-articular ligaments, extending be- 

 tween the actual articular surfaces of the femur and tibia.
