embryo

An embryo is a term given to a precursor of a fetus and in humans the term is usually considered to be between the first (1) and the eighth(8) week (eleventh week according to some reports) of development after fertilisation. The term "fetal pole" is sometimes used synonymously with the term embryo. Following this period, the term fetus is used.

Etymology

The term embryo is derived from the Greek word ἔμβρυον literally meaning "that which grows".
