During development, the outer parts of the two ducts fuse, forming a single urogenital canal that will become the vagina, cervix and uterus. [14] The cervix grows in size at a smaller rate than the body of the uterus, so the relative size of the cervix over time decreases, decreasing from being much larger than the body of the uterus in fetal ...
The uterine cavity is the inside of the uterus. It is triangular in shape, the base (broadest part) being formed by the internal surface of the body of the uterus between the openings of the fallopian tubes, the apex by the internal orifice of the uterus through which the cavity of the body communicates with the canal of the cervix. The uterine ...
The cervical canal is generally lined by "endocervical mucosa" which consists of a single layer of mucinous columnar epithelium. However, after menopause, the functional squamocolumnar junction moves into the cervical canal, and hence the distal part of the cervical canal may be lined by stratified squamous epithelium (conforming to a "type 3 transformation zone").
The uterus or womb is the major female reproductive organ. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo (weeks 1 to 8) and fetus (from week 9 until the delivery). In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth.
The round ligament of the uterus is a ligament that connects the uterus to the labia majora. It originates at the junction of the uterus and uterine tube. It passes through the inguinal canal to insert at the labium majus. The two round ligaments of uterus develop from the gubernaculum; they are the female homologue of the male gubernaculum ...
The vesicouterine pouch is a fold of peritoneum over the uterus and the bladder, forming a pelvic recess. [1] It is continued over the intestinal surface and body of the uterus onto its vesical surface, which it covers as far as the junction of the body and cervix uteri, and then to the bladder.
The uterine arteries reach the margins of the cervix in this fibrous tissue, while on either side the ureter runs downward and forward in it at a distance of about 2 cm. from the cervix. Posteriorly, the supravaginal cervix is covered by peritoneum, which is prolonged below on to the posterior vaginal wall, when it is reflected on to the rectum ...
The upper parts of the uterus remain separate, but the lower parts are fused into a single structure. Found in dogs, pigs, elephants, whales, dolphins, [37] and tarsiers, and strepsirrhine primates among others. Simplex The entire uterus is fused into a single organ. [35] It is found in higher primates, including humans, chimpanzees, and monkeys.
