The tendons of the index and of the middle finger are inserted to the base of the first phalanges of their digits. The tendon of the fourth digit is inserted similarly, but in addition has a tendinous slip running to the base of the second digit, taking the place of the absent perforatus and perforans. Flexor longus hallucis.-This has two heads-one fleshy from the lower face of the external condyle, with a tendinous slip from the outer side of the intercondylar notch; one tendinous and slight in common with the inner head of the flexor perforatus. The w-hole muscle is very slender. The tendon passes through the ankle-joint alongside that of the flexor communis, then crosses over that, giving off to it a slip which is thick relatively to the very slender tendon which runs to the base of the first phalanx of the thumb. Flexor profundus.-This common deep plantar tendon arises fleshy from the fibula and tibia, halfway down the tibial shaft, and its tendon after receiving slip from the longus hallucis breaks up into a branch, which runs to the base of the claw on digits II., III., and IV. Popliteus.-There is only one popliteal running from its fleshy origin from the head of the fibula to a fleshy insertion just under the head of the tibia. In the ankle-cartilage the tendons of the perforated and perforating flexors are most superficial; the tendon of the perforated muscle of the third digit wraps round that of the fourth. The tendon of the perforatus of the index is more deebly situated, and the tendon of the longus hallucis passes through the cartilage of the extreme outer side. Flexor brevis hallucis.-This is stronger than the longus hallucis. It arises from the upper part of the shaft of the tarso-metatarsus on the inner side. It is inserted at the base of the phalanx. Flexor brevis hallucis secundus.-This arises from the posterior side of the greater part of the shaft of the tarsus metatarsus and is inserted in common with the last. Flexor brevis indicis.-This is a short broad muscle lying in between the diverging ends of the metatarsal shaft, and inserted to the base of phalanx I. Adductor annularis.-This is a large muscle arising from the whole of the metatarsal shaft. Extensor hallucis.-A fleshy muscle from the middle quarter of the metatarsal shaft to the middle of the first phalanx. Extensor hallucis secundus.-A short entirely muscular slip with origin similar to the last, and insertion to the base of the first phalanx. Abductor indicis.-This is a very short muscle from the metatarsal shaft to the inner side of the basal phalanx. Extensor medii.-This is represented by a rudimentary patch of muscle attached to the fascia covering the base of the first phalanx. Adductor annularis.-This long muscle arises down the upper |
