Key Differences
Endometrium: Inner lining of the uterus. Myometrium: Thick, muscular layer of the uterus.
Endometrium: Changes during menstrual cycle. Myometrium: Remains relatively constant.
Endometrium: Shed during menstruation. Myometrium: Contracts during childbirth.
Endometrium: Supports embryo implantation. Myometrium: Provides structural integrity.
Endometrium: Thin, glandular layer. Myometrium: Consists of smooth muscle.

Compare with Definitions
Endometrium
Innermost lining of the uterus.
The endometrium thickens each menstrual cycle.
Myometrium
Provides uterine strength.
The myometrium supports the growing fetus.
Endometrium
Hormonally sensitive layer.
Estrogen affects the endometrium's growth.
Myometrium
Muscular wall of the uterus.
The myometrium contracts during labor.
Endometrium
Site for embryo implantation.
A healthy endometrium is crucial for conception.
Myometrium
Essential in childbirth.
Myometrium contractions help in delivering the baby.
Endometrium
Shed during menstruation.
Menstrual flow is partly endometrium.
Myometrium
Less affected by hormones.
The myometrium is more stable than the endometrium.
Endometrium
The endometrium is the inner epithelial layer, along with its mucous membrane, of the mammalian uterus. It has a basal layer and a functional layer; the functional layer thickens and then is shed during menstruation in humans and some other mammals, including apes, Old World monkeys, some species of bat, the elephant shrew and the Cairo spiny mouse.
Myometrium
Consists of smooth muscle.
The myometrium's smooth muscle enables contractions.
Endometrium
The glandular mucous membrane that lines the uterus.
Myometrium
The myometrium is the middle layer of the uterine wall, consisting mainly of uterine smooth muscle cells (also called uterine myocytes) but also of supporting stromal and vascular tissue. Its main function is to induce uterine contractions.
Endometrium
(anatomy) The mucous membrane that lines the uterus in mammals and in which fertilized eggs are implanted.
Myometrium
(anatomy) The smooth muscle forming the wall of the uterus.
Endometrium
The membrane lining the inner surface of the uterus, or womb.
Myometrium
The smooth muscle forming the wall of the uterus
Endometrium
(pregnancy) the mucous membrane that lines the uterus; thickens under hormonal control and (if pregnancy does not occur) is shed in menstruation; if pregnancy occurs it is shed along with the placenta at parturition
Endometrium
Undergoes cyclic changes.
The endometrium prepares for potential pregnancy.
Common Curiosities
What is the endometrium?
The uterus's inner lining.
What happens to the endometrium during menstruation?
It's shed if there's no pregnancy.
Is the myometrium thick?
Yes, it's a thick muscular layer.
Is the myometrium hormone-sensitive?
Less than the endometrium.
Can endometrium health affect fertility?
Yes, it's crucial for implantation.
What's the function of the myometrium during childbirth?
It contracts to help deliver the baby.
What's the role of myometrium?
Uterine muscular wall for contractions.
Does the endometrium change?
Yes, it changes with the menstrual cycle.
Is the myometrium always active?
Mostly during labor or contractions.
Can the myometrium develop tumors?
Yes, like uterine fibroids.
Does the endometrium regrow?
Yes, it regenerates each cycle.
Are there surgeries involving the endometrium?
Yes, like endometrial ablation.
Is the myometrium smooth muscle?
Yes, it's composed of smooth muscle.
Can disorders affect the endometrium?
Yes, like endometriosis.
Does the endometrium support pregnancy?
Yes, it's essential for nurturing the embryo.
