SOLE OF THE FOOT 



307 



Adductor hallucis (oblique head) 



and its smooth, glistening internal surface will be displayed. 



This appearance is due to the synovial membrane which 



lines it. The tendon is inserted into the plantar part of the 



base of the first metatarsal bone, and also to a slight degree 



into the adjacent part of the medial or first cuneiform bone. 



It likewise, in some cases, sends a slip to the base of the second 



metatarsal bone. As 



the tendon winds 



round the cuboid 



bone it is thickened, 



and contains a nodule 



of fibro- cartilage, or 



perhaps a sesamoid 



bone. 



Dissection, The dis- 

 section of the sole of the 

 foot is brought to an 

 end by disarticulating the 

 proximal end of the first 

 metatarsal bone. A good 

 view is thus obtained of 

 the continuity between the 

 dorsalis pedis artery and 

 the plantar arch.

 joint. The most im- 

 portant of the anas- 

 tomoses around the 

 knee-joint are placed 

 on the anterior aspect 

 of the articulation, 

 and take the form of 



three transverse arches. The uppermost of these arterial arcades 

 passes through the superficial fibres of the quadriceps extensor, 

 close to the proximal border of the patella, and is formed by the 

 union of a branch from the superior lateral genicular artery 

 with another from the articular branch of the arteria genu 

 suprema. The middle and lower transverse arches are both 

 placed under cover of the ligamentum patellae. The middle 

 arch runs across in the fatty tissue close to the distal end of the 

 patella. It is formed by the inferior lateral genicular artery, 

 and a branch which results from the union of a twig from the
