Rostral ( Schulze, 1893 ) : Toward the mouth along the longitudinal axis (Barclay, 1803) of the body; the opposite of caudal (Cleland, 1879); p. 6. Originally, toward the beak of a ship's prow ("rostrum"). In the BNA, His (1895) wrote, "The introduction of the word Rostrum for the cephalic pole of the axis of the body I deem an essential enrichment of our language. The adjective Rostral seems to me indispensable as an ontogentic expression." (p. 110; see translation by Eycleshymer, 1917, p. 109). Also see rostrocaudal axis.
