Venous drainage of the hand is accomplished superficially by small anastomosing (interconnecting) veins that unite to form the cephalic vein, coursing up the radial (thumb) side of the forearm, and the basilic vein, running up the ulnar side of the forearm and receiving blood from the hand, forearm, and arm.
Some larval forms appear very much like primitive chordates with a notochord (stiffening rod) and superficially resemble small tadpoles.
Extant sloths present an evolutionary conundrum in that the two living genera are superficially similar (small-bodied, folivorous, arboreal) but diverged from one another approximately 30 million years ago and are phylogenetically separated by a radiation of medium to massive, mainly ground-dwelling, taxa.
Mumblecore's origin myth locates the watershed at the 2005 South by Southwest Film Festival in Austin, Tex., which screened a cluster of small, superficially similar films (including "The Puffy Chair" and "Mutual Appreciation").
During the autumn they become dark brown to black in colour, hard, somewhat woody, and superficially similar to small conifer cones.
Despite their strictly subterranean mode of life, the African mole-rats possess small, superficially located and structurally normal eyes [8], [10] [12].
The longer superior parietal sulcus merges superficially with a small part of the left superior transverse parietal sulcus that courses onto the dorsal surface from the medial surface (Figs 1 and 7).
Superficially very little.
Superficially the variability at small n shows little resemblance to the variability at large n, which estimates phase over a longer interval.
Superficially, there were numerous small, torturous nerve fibers throughout the epidermis.
