Pectineus (Rectus anticus femoris of Meckel).—This is a long, 
thin, narrow strip of muscle arising from the spine of the pubis, ante- 
rior to the acetabulum, and passing straight down the inner side of 
the thigh; it degenerates into a small round tendon near the knee, 
which tendon traverses a pulley, formed by an oblique perforation in 
the strong rotular tendon of the extensors of the leg, and thus pass- 
ing across the knee-joint to the outer side of the leg, finally expands, 
and is lost in the flexor perforatus digitorum last described. It is 
this muscle which causes the toes to be bent when the knee is bent. 
Peroneus longus.—Origin: tendinous from the head of the tibia, 
and by carneous fibres from the upper half of the anterior margin of 
the tibia; these fibres pass obliquely to a marginal tendon, which 
becomes stronger and of a rounded form where it leaves the muscle. 
The tendon gives off a broad, thin, aponeurotic sheath to be inserted 
into the capsule of the tarsal joint ; it is then continued through a 
synovial pulley on the side of the outer malleolus, and is finally in- 
serted or continued into the perforated tendon of the middle toe. 
Tibialis anticus.—This muscle is overlapped and concealed by the 
peroneus; it arises partly in common with that muscle, and partly 
by separate short tendinous threads from the outer part of the head 
of the tibia; it gradually becomes narrower, and finally tendinous 
two-thirds of the way down the leg; its strong tendon glides 
through the oblique pulley in front of the distal end of the tibia, 
expands as it passes over the ankle-joint, and is inserted into the 
anterior part of the proximal end of the tarso-metatarsal hone, sending 
off a small tendinous slip to the aponeurosis covering the extensor 
tendons of the toes, and a strong tendon which joins the fibular side 
of the following muscle. 
Extensor longus digitorum.—This lies between the tibialis anticus 
and the front and outer facet of the tibia, from which it derives an 
extensive origin; its tendon commences half-way down the leg;runs 
along the anterior part of the bone, first under the broad ligamentous 
band representing the anterior part of the annular ligament, then 
through a ligamentous pulley, and inclines to the inner or tibial side 
of the anterior surface of the metatarsal bone, where it expands and 
divides into three tendons. Of these the innermost is given off first, 
and subdivides into two tendons, one of which goes to be inserted into 
the base of the last phalanx of the second toe; the other portion is 
principally inserted into the middle toe, but also sends off a small 
tendon to the inner side of the proximal phalanx of the second toe. 
The second tendon is inserted by distinct portions into the second, 
third and last phalanges of the middle toe. The third tendon supplies 
the outer toe. 
Extensor brevis digitorum.—A small extensor muscle arises from 
the insertion of the tibialis anticus, and sends its tendon to the outer 
side of that of the great evtensor digitorum. 
Lixiensor pollicis brevis.—An extensor of the small innermost toe 
arises from the upper and inner side of the tarso-metatarsal bone. 
Flexor perforans digitorum.—This strong penniform muscle arises 
fleshy from nearly the whole of the outer surface of the fibula, also
