the external female reproductive organs are called
The vulva
-Its rounded, soft fullness of
subcutaneous fatty tissue, prominence over the symphysis pubis that forms
the anterior border of the external reproductive organs.
Mons Pubis
are two rounded, fleshy folds of tissue that extend from
the mons pubis to the perineum.
-It protects the labia minora, urinary meatus and vaginal introitus.
Labia Majora
It is located between the labia majora, are narrow.
-The lateral and anterior aspects are usually pigmented.
-The inner surfaces are similar to vaginal mucosa, pink and mois.
-Their rich vascularity.
Labia Minora
The term clitoris comes from a Greek word meaning key.
-Erectile organ.
-It’s rich vascular, highly sensitive to temperature, touch, and pressure sensation
Clitoris
- Is an oval-shaped area formed between the labia minora, clitoris, and fourchette.
-Vestibule contains the external
urethral meatus, vaginal introitus, and Bartholin’s glands.
Vestibule
-Is the most posterior part of the external female reproductive organs.
Perineum
It is an elastic fibro-muscular tube and membranous tissue about 8to10cm long.
Vagina
Function of the Vagina:
● To allow discharge of the menstrual flow.
● As the female organs of coitus.
● To allow passage of the fetus from the uterus.
To supports and protects the lower abdominal and internal reproductive organs.
Bony Pelvis
Is the outer peritoneal
layer of serous membrane that covers most of the uterus.
Perimetrium
Is the middle layer of
thick muscle.
Myometrium
- Is the inner layer of the uterus.
- It is responsive to the cyclic variations of estrogen and progesterone during the female reproductive every month.
Endometrium
Oval solid structure, 1.5 cm in
thickness, 2.5 cm in width and 3.5 cm in length respectively. Each weigh about 4-8 gm.
Ovaries
Structure of the ovaries
● Cortex
● Medulla
● Hilum
Function of the ovary:
● Secrete estrogen & progesterone.
● Production of ova
● Its normal position is anteverted (rotated
forward and slightly anteflexed (flexed
forward)
- The upper part is the corpus, or body of the uterus
- The fundus is the part of the body or corpus above the area where the fallopian tubes enter the uterus.
- Length about 5 cm.
Body of the uterus
- A narrower transition zone.
- Is between the corpus of the uterus and cervix.
- During late pregnancy, the isthmus elongates and is known as the lower uterine segment.
Isthmus
- The lowermost position of the uterus “neck”.
- The length of the cervix is about 2.5 to 3 cm.
Cervix
- The two tubes extended from the
cornus of the uterus to the ovary. - It runs in the upper free border of the
broad ligament. - Length 8 to 14 cm average 10 cm
- It’s divided into 4 parts
Fallopian tubes
What are the 4 parts of fallopian tubes
Interstitial part
Isthmus
Ampulla
Infundibulum
Which runs into the uterine cavity, passes through the myometrium between the fundus and body of the uterus. About 1-2 cm in length
Interstitial part
- Which is the narrow part of the tube adjacent to the uterus.
- Straight and cord-like, about 2-3 cm in length.
Isthmus
● Which is the wider part about 5cm in length.
● Fertilization occurs in the ampulla
Ampulla
