NERVES OF THE LOWER LIMB. 



a. Small mn-^cnlcw branches are supplied to the abductor pollicis and flexor 

 brevis dig'itormn. 



h. Small j)la nta y cutaneous branches perforate the plantar fascia to ramify in 

 the integument of the sole of the foot. 



e. The dirjital hranclies are named numerically from within outwards : the 

 three outer pass from under cover of the plantar fascia near the clefts between 

 the toes. The first or innermost branch continues single, but the other three 

 bifurcate to supply the adjacent sides of two toes. These branches require 

 separate notice. 



The first digital branch is that destined for the inner side of the great toe ; it 

 becomes subcutaneous farther back than the others, and sends off a branch to 

 the Jicxo7- hrv is jwUicis.

The flexor communis brevis, the abductor poliieis 

 and abductor minimi digiti, a part of the tendons 

 of the flexor communis longus, together with the lum- 

 bricales muscles, have been removed so as to bring 

 into view the transversus and interossei in the middle 

 of the foot. 



a, upon the posterior extremity of the flexor com- 

 munis brevis, near which, descending over the heel, 

 are seen ramifications of the calcaneal branch of 

 the posterior tibial nerve ; h, abductor pollicis ; c, 

 tendon of the flexor communis longus divided close to 

 the jjlace where it is joined by the flexor accessorius ; 

 d, abductor minimi digiti ; e, tendon of the flexor 

 longus pollicis between the two portions of the flexor 

 brevis pollicis ; 1, internal plantar nerve giving some 

 twigs to the abductor pollicis, and 1', a branch to the 

 flexor communis brevis, cut as it lies on the acces- 

 sorius ; 2, inner branch of the internal plantar nerve 

 giving branches to the abductor pollicis, flexor brevis 

 pollicis, and forming, 2', the internal cutaneons of 

 the great toe ; 3, continuation of the internal jflautar 

 neiwe, dividing subsequently into three branches, 

 which form, 3', 3', 3', the collateral plantar cutaneous 

 nerves of the first and second, second and third, and 

 third and fourth toes ; 4, the external plantar nerve ; 

 4', its branch to the abductor minimi digiti ; 5, twig 

 of union between the plantar nerves ; 6, superficial 

 bi-anch of the external plantar nerve ; subsequently 

 dividing into 6', 6', the collateral cutaneous nerves of 

 the fourth and fifth toes and the external nerve of the fifth ; 7, deep bi-anch of the 

 external plantar nerve giving twigs to the adductor pollicis, the interossei, the trans- 

 versaUs, and to the third and fourth lumbricales muscles. 



Tlie second branch having reached the interval between the first and second 

 metatarsal bones, furnishes a small twig to the first lumhricalis muscle, and 

 bifurcates behind the cleft between the great toe and the second to supply their 

 contiguous sides. 



The third digital branch, corresponding with the second interos.seous space, 

 gives a slender filament to the second luinhricalls muscle, and divides in a manner 

 similar to that of the second branch into two offsets for the sides of the second 

 and third toes. 



The fourth digital branch distributed to the adjacent sides of the third and 

 fourth toes, receives a communicating branch from the external plantar 



Along -the sides of the toes, cutaneous and ai-ticular filaments are given from
