Does Anterior refer to the anatomical rear?
The most obvious end-points are the "nose" and "tail" and anterior refers to the head or front while posterior refers to the rear. Anatomically, the nose is referred to as the anterior end coming from the Latin word for before. In organisms like vertebrates, that have distinct heads, anterior can be classified as rostral end (beak), cranial end (skull), or cephalic end (head). However, for borader applicability, especially in organisms without distinct heads such as invertibrates, "anterior" is usually preferred as beginning and end of the organism is ambiguous.
