GENERAL HISTOLOGY

Detailed explanation-1: -The lower part of the uterus connects to the vagina and is called the cervix. The wider, upper part of the uterus is called the corpus or fundus. The uterus has 3 layers: Endometrium.

Detailed explanation-2: -The lower end of the cervix bulges through the anterior wall of the vagina, and is referred to as the vaginal portion of cervix (or ectocervix) while the rest of the cervix above the vagina is called the supravaginal portion of cervix.

Detailed explanation-3: -All the internal organs are located in the pelvis, which is the lower part of the abdomen between the hip bones. The cervix is the lower, narrow part of the uterus (womb). The cervix connects the main body of the uterus to the vagina (birth canal).

Detailed explanation-4: -The lower third of the uterus comprises the cervix. The upper boundary of the cervix is the level of the internal os, a narrowing of the uterus that is also referred to as the isthmus. The internal os is the opening between the cervix and the corpus. The external os is the opening between the cervix and vagina.
