third metacarpal वाक्य

The fibres end approximately at the middle of the forearm in the form of a flat tendon, which is closely connected with that of the extensor carpi radialis longus, and accompanies it to the wrist; it passes beneath the abductor pollicis longus and extensor pollicis brevis, beneath the extensor retinaculum, and inserts into the lateral dorsal surface of the base of the third metacarpal bone, with a few fibres inserting into the medial dorsal surface of the second metacarpal bone.
The monophyly of Centrolenidae is supported by morphological and behavioral characters, including : 1 ) presence of a dilated process on the medial side of the third metacarpal ( an apparently unique synapomorphy ); 2 ) ventral origin of the musculus flexor teres digiti III relative to the musculus transversi metacarpi I; 3 ) terminal phalanges T-shaped; 4 ) exotroph, lotic, burrower / fossorial tadpoles with a vermiform body and dorsal C-shaped eyes, that live buried within leaf packs in still or flowing water systems; and 5 ) eggs clutches deposited outside of water on vegetation or rocks above still or flowing water systems.
