164 ANATOMY IN A NUTSHELL. 



Ossification. — One center. 



Articulation. — With four bones: (1) navicular, (2) middle cuneiform; 

 (3) first and (4) second metatarsal bones. 



Attachment of Muscles. — (1) Tibialis anticus and (2) posticus and (3) 

 Peroneus longus. 



Middle cuneiform, supplied by dorsalis pedis. 



i >ssification. — One center. 



Ai;ii< qlation. — With four bones, navicular, internal and external cunei- 

 form and second metatarsal bone. 



Attachment of Muscles. — A slip from the tendon of the Tibialis posticus 

 is attached to this bone. 



External cuneiform, supplied by dorsalis pedis. 



Ossification. — One center. 



Articulation. — With six bones; the navicular, middle cuneiform, cuboid, 

 second, third, and fourth metatarsal bones. 



Attachment of Muscles. — Two: part of Tibialis posticus, Flexor brevis 

 hallucis. 



Metatarsus. Plates LII-LIII. 



Blood Supply. — They all have small nutrient branches from interosseous. 



Ossification. — Each metatarsal bone has two centers. Plate LIV. 



Articulation. — Each bone articulates with the tarsal bones by one ex- 

 tremity, and by the other with the first row of phalanges. The number of tarsal 

 bones with which each metatarsal articulates is one for the first, three for the 

 second, one for the third, two for the fourth, and one for the fifth. 



Attachment of Muscles. — To the first metatarsal bone, three, part of the 

 Tibialis anticus, the Peroneus longus, and First dorsal interosseous. To the 

 second, four, the Adductor obliquus hallucis and First and Second dorsal inter- 

 osseous, and silp from the tendon of the Tibialis posticus, and occasionally a 

 slip from the Peroneus longus. To the third, five, the Adductor obliquus hallucis, 

 Second and Third dorsal and Plrst plantar interosseous, and a slip from the 

 tendon of the Tibialis posticus. To the fourth, five, the Adductor obliquus 

 hallucis. Third and fourth dorsal, and Second plantar interosseous, and a slip 

 from the tendon of the Tibialis posticus. To the fifth, six, the Peroneus brevis 

 Peroneus tertius, Flexor brevis minimi digiti, Adductor transversus hallucis. 

 Fourth dorsal and Third plantar interosseous. 



Phalanges. Plates LII-LIII. 



Blood Supply. — They all have small nutrient branches from digital. 



Ossification.- From two centers. Plate LIV. 



Artk i LATION. The first row, with the metatarsal bones behind and sec- 

 ond phalanges in front ;the second row of the four outer toes, with the first and 

 third phalanges; of the great toe, with the first phalanx: the third row of the 

 loin- outer toes, with the second phalanges. 



Attachment ok Muscles.- To the first phalanges. Great toe, five mus- 

 cles; innermosl tendon of Extensor brevis digitorum, Abductor hallucis, Ad- 

 ductor obliquus hallucis, flexor brevis hallucis, Adductor transversus hallucis.
