130 HUMAN ANATOMY. 



The arteries of the first row are tarsal from dorsalis pedis, 

 external malleolar from anterior tibial, and branches of peroneal 

 from posterior tibial. 



Nerves, from posterior tibial, or plantar. 



THE SECOND ROW .are firmly held together by dorsal, plantar, 

 and interosseous ligaments. The two former unite the dorsal 

 and plantar . surf aces and the interosseous, four strong bands 

 connect the scaphoid and cuboid, the internal and middle, the 

 middle and external cuneiforms, and the external cuneiform 

 and cuboid. 



The arteries of the second row are from plantars and meta- 

 tarsals. Nerves, from anterior tibial, and internal and external 

 divisions of posterior tibial nerves. 



THE TWO ROWS OF THE TARSUS are connected with each 

 other by three sets of ligaments, first between os calcis and 

 cuboid, consisting of superior and internal calcaneo-cuboid, long 

 and short calcaneo-cuboid; second, between os calcis and sca- 

 phoid, consisting of superior and inferior calcaneo-scaphoid ; and 

 third, between astragalus and scaphoid, consisting of a single 

 superior astragalo-scaphoid ligament, a band passing from neck 

 of astragalus to upper surface of scaphoid. 



Calcaneo-cuboid. The superior passes between dorsal sur- 

 faces of os calcis and cuboid. The internal, passing from os 

 calcis to inner side of cuboid, is one of the main bonds of union 

 between the two rows of tarsus. 



The inferior firmly connects the bones below, the lig amen- 

 tum longce plantce passing from os calcis forward to the plantar 

 surface of the cuboid, and sending fibres forward to bases of 

 second, third, and fourth metatarsal bones; the ligamentum 

 breve plantce passing from fore and under surface of os calcis to 

 under surface of cuboid. The two preceding are important in 

 preserving the arch of the foot. 



The superior and inferior calcaneo-scaphoid pass above and 

 below these bones, firmly connecting them. 



The arteries of the mediotarsal joints are derived from the 

 anterior tibial, tarsal, metatarsal, or external plantar. 



Nerves, from external branch of anterior tibial. 



THE TARSO-METATARSAL ARTICULATIONS are firmly held to- 

 gether by dorsal and plantar ligaments, and connected with one 

 another by interosseous bands, three in number, passing between 

 internal cuneiform and second metatarsal bone, external cunei- 

 form and second metatarsal, and external cuneiform and third 

 metatarsal. 



The arteries are from metatarsal, dorsalis pedis, and deep 

 plantar arch-
