Textbook Question

More than one choice may apply.
The myometrium is the muscular layer of the uterus, and the endometrium is the_________layer.
a. serosa
b. adventitia
c. submucosa
d. mucosa

Verified step by step guidance

Understand the anatomy of the uterus: The uterus has three main layers. The outermost layer is the perimetrium (serosa), the middle layer is the myometrium (muscular layer), and the innermost layer is the endometrium.

Recall the definition of mucosa: Mucosa refers to the innermost lining of organs that are exposed to the external environment or involved in secretion and absorption. It typically consists of epithelial tissue and underlying connective tissue.

Compare the structure of the endometrium to mucosa: The endometrium is composed of epithelial cells, glands, and connective tissue, which aligns with the characteristics of mucosa.

Eliminate incorrect options: The serosa (a) is the outermost layer of the uterus, not the innermost. The adventitia (b) is a connective tissue layer found in organs like the esophagus, not the uterus. The submucosa (c) is a layer beneath the mucosa, but the endometrium itself is the mucosa.

Conclude that the endometrium is the mucosa layer of the uterus, based on its structure and function.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Myometrium

The myometrium is the thick, muscular middle layer of the uterus, responsible for the contractions during labor and menstruation. It consists of smooth muscle fibers that allow for expansion and contraction, playing a crucial role in reproductive processes.

Endometrium

The endometrium is the innermost lining of the uterus, which undergoes cyclical changes during the menstrual cycle. It is composed of a mucosal layer that thickens in preparation for potential implantation of a fertilized egg and sheds during menstruation if no pregnancy occurs.

Uterine Layers

The uterus has three primary layers: the outer serosa, the middle myometrium, and the inner endometrium. Understanding these layers is essential for comprehending uterine function, including menstruation, pregnancy, and childbirth, as well as their roles in various gynecological conditions.

Textbook Question

Gina Marciano, a 44-year-old mother of eight children, visited her physician complaining of a 'bearing down' sensation in her pelvis, low backache, and urinary incontinence. A vaginal examination showed that the external os of her cervix was just inside the vaginal orifice and her perineum exhibited large keloids (masses of scar tissue). What do you think Gina's problem is and what caused it? (Be anatomically specific.)

Multiple Choice

The uterine wall and the vaginal wall share some superficial similarities. For example, in both structures, the middle layer is composed of:

Crystal had both her left ovary and her right uterine tube removed surgically at age 17 because of a cyst and a tumor in these organs. Now, at age 32, she remains healthy and is expecting her second child. How could Crystal conceive a child with just one ovary and one uterine tube, separated on opposite sides of the pelvis?
