The Federal Aviation Agency's name changed to the Federal Aviation Administration as it became one of several agencies (e.g., Federal Highway Administration, Federal Railroad Administration, the Coast Guard, and the Saint Lawrence Seaway Commission) within DOT (albeit the largest).
The endometrium is the tissue lining the inner cavity of the uterus (or womb). The uterus, a hollow organ about the size and shape of a pear, is found in a woman's pelvic region and is the organ where the fetus grows until birth. The upper part of the uterus is called the corpus; the lower, narrower part of the uterus is called the cervix. The cervix is the opening between the uterus and the vagina. The outer layer of the uterus is called the myometrium. The myometrium is thick and composed of strong muscles.
Cervical, Endocervical, and Endometrial Polyps. The endometrium is the inside lining of the uterus. The cervix is the lower part of the uterus that extends down into the top of the vagina. A polyp is a mass of tissue projecting from a mucous membrane, such as the cervix or endometrium. A pedunculated polyp is attached to the mucous membrane by a stalk, which is its blood supply. Endometrial polyps are overgrowths of endometrial glands and stroma in the endometrium. Cervical and endocervical polyps are the most common benign, neoplastic (new) growths of the cervix. Cervical polyps (also referred to as ectocervical) grow on the outside of the cervix.
