metra (English spelling)

…Many mammals have a double uterus, a septate uterus, or a bicornuate uterus, and the single uterus of primates, including humans, has a similar shape if you include the fallopian tubes. The tubular part that leads to the opening of the vagina is called a metora ("Animals"). Metra also includes the meaning of mother matēr, and since it includes the function of nurturing the fetus, it is probably a more accurate word than the word womb as a place where the child lives. …
