Show 368 PROF. K. V O N BARDELEBEN O N THE [Apr. 17, Beneath this tendon there is an oblique muscle like a muse. transversus s. obliquus carpi. From the fascia arises a weak muscle which seems to be the remains of the flexor brevis superflcialis. There are also an abductor minimi and an " opponens" which forms the outer part of the flexor brevis superflcialis. The tibialis posticus (or medialis?) is inserted:- (1) By an aponeurotic triangular expansion on the Ph.; (2) it gives origin to a strong muscular belly (like a lumbricalis) ending in a tendon which goes to phalanx II. of the 2nd toe; it is perforated by the tendon of the profundus (-fibularis); (3) it continues into a tendon which joins the flexor digit, profundus, where it sends the tendon to the hallux. " Tibialis quartus" I should like to name a muscle which is situated on the outer side of the " tibialis posticus" It seems to be rudimentary or reduced ; I could not find the insertion, because the tendon was torn on the back of the os trigonum. The flexor digitorum sublimis (tibialis) goes to toes 3-5 ; first it is fleshy for a long way, then tendinous, and finally fleshy again (=.lumbricalisi!). The sublimis is largely connected with the profundus (fibularis), contra Dobson. 8. Extensores. The nerv. peronaeus goes to the 5th, 4th, 3rd, and 2nd toes (half). There are four m. peroncei : Origin. (1) Cond. lat. femoris. (2) Cond. lat. fern., head of the fibula (lat.), representing a fleshy lig. laterale. (3) a. Middle third of fibula, outside. b. Femur, connected with (1). (4) Anterior surface of the fibula, upper half. Peculiarities. Superficial, strong, behind (2). First flat, then rounded. Strongest tendon of all peronsei. Between (1) and (3 a). Insertion. Planta. Metat. V., 5th toe. Outer border of the foot. Dorsal aspect of the 5th, 4th, 3rd toes. 2. TRICHOSURUS VULPECOLA. The 2nd and 3rd toes reduced and united; hallux widely diverging. a. Flexores. The gastrocnemius is strong, two-headed, takes origin from the femur; inserted into the tuberositas calcanei. The plantaris is also strong ; inserted into the tuberos. calc. and fascia plantaris. The flexor brevis digitorum superflcialis arises from the tendon of the plantaris and ends on the outer border of the foot. |
