Child Bearing Anatomy Flashcards
Mons Pubis
fat pad on top of the pubic bone that cushions the pelvis
Labia Majora and Minora
Rich in sebaceous glands (lubrication and bactericide). Provides protection for inner structures
Clitoris
Rich in blood and nerves. Secretes smegma (odour is a sexual stimulant)
Paraurethral Glands
Lubricates vaginal vestibule to facilitate intercourse
Bartholin’s Glands
secretes a clear, thick, alkaline (acidic) substance that enhances viability and mobility of sperm
Perineum
wedge shaped area between vagina and the anus
What are the two sections of the uterus?
Corpus (upper 2/3)
isthmus (lower 1/3)
what are the three layers of the uterus?
Perimetreum (outer layer)
Myometrium (muscular middle layer)
Endometrium (inner mucous membrane, influenced by hormones)
What are the three layers of the Myometrium
Outer layer: top portion of the uterus. Has longitudinal fibers to push down on the baby.
Middle layer: interlacing fibers in a figure 8/wave pattern. surrounds blood vessels and acts as a tourniquet to stop bleeding after birth
Inner layer: horizontal fibers that circle the uterus. Act as a sphincter at the internal os of the cervix
What is the purpose of the myometrium being continuous with the fallopian tubes, vagina, and ligaments?
Allows the organs to present a unified reaction during ovulation and orgasms. All layers act as a whole
Cervix
the neck of the uterus
Internal and external Os
Internal and external openings of the cervix
What are the 4 types of pelvises?
Glynecoid - most favourable (normal heart shape)
Android - not favourable. heart is smaller (male like) fetal head enters in transverse or posterior position.
Antrhropoid - vertically elongated heart shape. Favourable
Platypelloid - horizontally elongated heart shape. not favourable. fetal head engages in
transverse position
What is the Bregma (frontal fontanelle)?
Large diamond shaped intersection between frontal cranial sutures (much larger than posterior)
Define Mentum
Fetal chin
