Make the maximal movements in the joint in the direction of 

 (1) extension, (2) flexion, (3) adduction, (4) abduction, (5) rota- 

 tion medialward, (6) rotation lateralward, (7) circumduction. 

 How are the ligaments affected in each instance ? What muscles 

 are concerned in each movement in the living body ? 



Open the articulation. Eemove the whole capsule first, with 

 the exception of the ligamentum iliof emorale. Test the strength 

 of this and then remove it. 



Study each of the following ligaments : 



(a) Glenoid lip (labrum glenoidale] (0. T. cotyloid ligament). 



(b) Transverse ligament of acetabulum (ligamentum transversum ace- 



tabuli) . 



(c) Round ligament of the femur (ligamentum teres femoris). 



This would be better designated " triangular ligament," or, better 

 still, Lig. intrarticulare coxae, a name suggested by Fick. It is 

 probable that it is a vestige of a pubofemoral muscle the tendon 

 of which has become invaginated into the joint. 



Study the blood supply and nerve supply of the joint. (Cf. 

 Poirier et Charpy, t. i., Figs. 731 and 732.) Follow the reflec- 

 tions of the synovial membrane. 



Cut through the ligamentum teres, remove the lower extrem- 

 ity from the trunk, and continue the dissection at a side-table. 



LEG AND FOOT. 



Make the following incisions: (1) an incision distalward 

 along the middle line of the leg and dorsum of the foot, in front, 

 extending as far as the base of the middle toe; (2) transverse 

 incisions extending (a) across the ankle and (b) across the bases 

 of the toes. Reflect the flaps thus formed, taking no fat with the 

 skin. 



Superficial Fascia. 



Note the characteristics of this fascia and determine with 

 what fasciae it is continuous above and below. Dissect out the 

 following : 



Veins. (Vide Spalteholz, Figs. 507-509.) 



(a) Dorsal digital veins of foot (Vv. digitales dor sales pedis}. 



(b) Intercapitular veins (Vv. int er capitular e s] . 



(c) Common digital veins of foot (Vv. digitales communes pedis). 



(d) Dorsal venous arch of foot (arcus venosus dorsalis pedis (cuta- 



neus)). 



(e) Dorsal cutaneous venous network of foot (rete venosum dorsale 



pedis cutaneum).
