58 THE POCKET ANATOMY 



(Anterior tibial). [Extends toes and flexes tarsal joints.] 

 Inner tendon crosses dorsalis pedis artery. 



FOOT, PLANTAR REGION, 1ST LAYER. 



Abductor hallucis : inner side of large tubercle on under 

 surface of os calcis, plantar fasci-a, internal annular ligament 

 (p)--inner side of base of ist phalanx of great toe(-r) (Internal 

 plantar). [Abducts great toe.] 



Flexor brevis digitorum : front part of inner tubercle of os 

 calcis(T), plantar fascia(F), intermuscular septa(p) four 

 tendons, which on the ist phalanx divide into two, allowing 

 long flexor tendons to pass through ; the slips then reunite 

 and are inserted, again separating, into the sides of the bases 

 to middle phalanges of four outer toes(T) (Internal plantar) 

 [Flexes tarsal joints and first interphalangeal joint of toes.] 



Abductor minimi digiti: outer tubercle and fore part of 

 inner tubercle of os calcis, plantar fascia, intermuscular 

 septa(r) outer side of base of ist phalanx of little toe 

 (External plantar). [Abducts little toe.] - 



FOOT, PLANTAR REGION, 2ND LAYER. 



Flexor accessorius : Inner head. Inner concave surface of 

 os calcis(p). Outer head. Outer surface of os calcis in front 

 of outer tubercle, long plantar ligament (T) long flexor 

 t-ndons(p) (External plantar). [Flexes toes, correcting 

 obliquity of pull of the flexor longus digitorum.] 



Lumbricales : long flexor tendons, from adjacent sides of 

 two tendons, except most internal one, which arises from 

 inner side of ist flexor tendon (F) inner sides of bases of ist 

 phalanx of four outer toes, and dorsal expansion of extensor 

 tendon(T) (Internal plantar, ist ; External plantar, 2nd, 3rd, 

 and 4th). [Flex metatarso-phalangeal and extend inter- 

 phalangeal joints.] 



FOOT, PLANTAR REGION, 3RD LAYER. 



Flexor brevis hallucis: internal border of cuboid and 

 adjacent part of external cuneiform(T), tendon of tibialis 

 posticus(T) outer and inner sides of base of ist phalanx 

 of great toe(T) (Internal plantar). [Flexes great toe and 

 adducts it to middle line of foot.] 



Adductor obliquus hallucis ; bases of 2nd, 3rd, and 4th 

 metatarsals, sheath of peroneus longus(p) outer side of base 

 of ist phalanx of great toe(T) (External plantar). [Adducts 

 great toe.] 



Adductor transversus pollicis : capsules of metatarso-
