A

Clitoris

27
Q

A small pea-shaped structure. It plays an important part in sexual excitement in females.

A

Clitoris

28
Q

Bartholin’s glands are situated one on each side near the vaginal opening. They are about the size of a small pea and their ducts open into the vestibule immediately lateral to the attachment of the hymen.

A

Vestibular Glands

29
Q

They secret mucus that keeps the vulva moist.

A

Vestibular Glands

30
Q

Roughly triangular area extending from the base of the labia minora to the anal canal.

A

Perineum

Q

It consists of connective tissue, muscle, and fat. It gives attachment to the muscles of the pelvic floor.

A

Perineum

32
Q

A

Uterus

33
Q

The dome-shaped part of the uterus above the openings of the uterine tubes.

A

Fundus

34
Q

Anteriorly it lies of the fundus and the body where it is folded on to the upper surface of the urinary bladder. This fold of peritoneum forms the vesicouterine pouch.

A

Perimetrium

35
Q

Posteriorly, the peritoneum covers the fundus, the body and the cervix, then it folds back on to the rectum to form the rectouterine pouch.

A

Perimetrium

36
Q

The thickest layer of tissue in the uterine wall. It is a mass of smooth muscle fibers interlaced with areolar tissue, blood vessels and nerves.

A

Myometrium

37
Q

Made up of the Columnar epithelial cells, consist mucous secreting tubular glands.

A

Endometrium

38
Q

These are formed by a double fold of peritoneuma, one on each side of the uterus.

A

Broad Ligaments

39
Q

These are brands of fibrous tissue between the two layers of broad ligament.

A

Round ligament

40
Q

These originate from the posterior walls of the cervix and vagina and extend backwards, one on each side of the rectum, to the sacrum.

A

Uterosacral ligaments

41
Q

These extend one from each side of the cervix and vagina to the side walls of the pelvis.

A

Transverse Cervical Ligaments

42
Q

These are the fallopian tubes. They propel the ovum from the ovary to the uterus by peristalsis and ciliary movement.

A

Uterine Tubes

43
Q

The secretions of the uterine tube nourish both
________.

A

ovum and spermatozoa

44
Q

Where does the fertilization of the ovum take place?

A

Uterine Tubes

45
Q

Where is the zygote propelled into for implantation?

A

Uterus

46
Q

These are the female gonads. They lie in a shallow fossa on the lateral walls of the pelvis and store female gametes.

A

Ovaries

47
Q

The maturation of ovaries is controlled by the ____ and ____.

A

Cortex

51
Q

These contain an ovum.

A

52
Q

This is the main part of the vagina. It is narrowest inferiorly at the internal os where it is continuous with the cervix.

A

Body

53
Q

59
Q

Breast itself is covered in _____.

A

subcutaneous fat

60
