uterus Audio Help (y

'tər-əs) Pronunciation Key
Plural uteri (y

'tə-rī') or uteruses
The hollow, muscular organ of female mammals in which the embryo develops. In most mammals the uterus is divided into two saclike parts, whereas in primates it is a single structure. It lies between the bladder and rectum and is attached to the vagina and the fallopian tubes. During the menstrual cycle (estrus), the lining of the uterus (endometrium) undergoes changes that permit the implantation of a fertilized egg. Also called womb. See more at menstrual cycle.

Uterus

U"te*rus\, n. [L.]

1. (Anat.) The organ of a female mammal in which the young are developed previous to birth; the womb.

Note: The uterus is simply an enlargement of the oviduct, and in the lower mammals there is one on each side, but in the higher forms the two become more or less completely united into one. In many male mammals there is a small vesicle, opening into the urinogenital canal, which corresponds to the uterus of the female and is called the male uterus, or [NL.] uterus masculinus.

2. (Zo["o]l.) A receptacle, or pouch, connected with the oviducts of many invertebrates in which the eggs are retained until they hatch or until the embryos develop more or less. See Illust. of Hermaphrodite in Append.
