The lumbricales pedis are four fmall mufcles in the 

 fole of the foot, fo called from their refemblanee in 

 fize and appearance to earth-worms : they arife from 

 the four tendons of the flexor digitorum longus, and 

 are inferted into the infide of the firft joint of the four 

 fmall toes. Thefe mufcles render the flexion of the 

 toes more extenfive, and draw them inwards. 



The mufcles fituated chiefly on the foot are thofc de- 

 figned for the motions of each of the toes in particular. 

 To the great toe belong five mufcles. Of thefe, one 

 extends 'it, two bend it, one draws it outwards, and 

 another inwards. 



The little toe, befides the common flexors and ex- 

 tenfors, has two mufcles proper to itfelf. One of thefe 

 draws it outwards, and the other contributes to its 

 flexion. 



Between the metatarfal bones are alfo feated feven 

 mufcles, called the interoflei interni et externi. The 

 internal interoflei are three in number ; their ufe is to 

 draw the three fmaller toes towards the great toe. The 

 external interoflei are four; of thefe, the firft ferves 

 to move the fore-toe towards the great-toe ; the other 

 three draw the three toes next the great toe outwards. 

 All the interoflei aflift in extending the toes. 



The tranfverfalis pedis arifes from the under part of 

 the anterior extremity of the metatarfal bone of the 

 great toe, and terminates at that of the metatarfal bone 

 of the little toe. By the contraftion of this mufcle the 

 great and little toes are brought nearer. 



The mufcles fituated in the foot are covered and 

 protected by a ftrong tendinous expanfion, which 

 pafies from the os calcis to the firft joints of all the 

 toes.
