Term
location of ovaries
Definition
-lateral wall of abdominopelvic cavity
-approximately at the level of the anterior superior iliac spine
Term
function of ovaries
Definition
-production of mature ova
-endocrine gland produces two hormones: estrogen and progesterone
Term
2 portions of ovary
Definition
medulla- nerves and blood vessels. center portion
cortex- thousands of follicles in different stages of development
Term
primordial
Definition
primary follicles(ova and surrounding capsule). approximately 400,000 at birth
Term
secondary follicles
Definition
-second maturational stage
Term
graafian follicles
Definition
mature ova which rupture from surround follicle during ovulation
Term
corpus luteum
Definition
-"glandular structure" which develops from ofllicle after ova has been extruded
-secretes estrogen and progesterone
Term
corpus albicans
Definition
degenerated corpus luteum
Term
uterine tubes (fallopian tubes, oviducts)
Definition
-extend laterally from uterus
-muscular tube approximately 10 in. long
-has finger-like projections called fimbriae
-transport ova from ovaries to uterus
-site of fertilizaion
Term
uterus location
Definition
-between bladder and rectum
-generally ante flexed, tilted slightly anteriorly
Term
uterus function
Definition
-provides a site for implantation of fertilized ova
-houses developing fetus
-capable of contraction during delivery to aid in the birthing process
Term
uterus structure
Definition
-hollow, pear shaped organ
-thick, muscular walls
-regions: fundus, body, cervix
Term
uterine wall
Definition
-perimetrium- thin outer CT covering
-myometrium- middle layer composed of smooth muscle
-endometrium- stratum functionale: superficial layer shed during menstration. stratum basal: deep to stratum functionale. vascular and rebuilds layer
Term
vagina location
Definition
-extends from uterus to external orifice
-posterior to bladder and urethra and anterior to rectum
Term
fornices
Definition
spaces formed by the protrusion of the cervix into the vagina
Term
vaginal orifice
Definition
between urethral orifice and the anus
Term
hymen
Definition
membrane which may partially cover the vaginal orifice
Term
vaginal wall
Definition
-mucosal layer: innermost. composed of stratified squamous. mucous glands present which secrete acidic environment
-muscular layer- composed of smooth muscle
-fibous layer- outermost layer, CT
Term
mons pubis
Definition
pad of adipose tissue that covers symphysis pubis
Term
labia majora
Definition
outermost, thickened, longitudinal folds of skin which protect genetalia
Term
labia minora
Definition
medial, small folds of skin located medial to labia majora
Term
clitoris
Definition
small, rounded projection composed of erectile tissue located anterior to urethral orifice
Term
vestibule
Definition
-region enclosed by labia minora
-contains vaginal and urethral orifices
-vestibular glands secrete mucous into vestibule to lubricate vaginal orifice
Term
perineum
Definition
a triangular region bounded anteriorly by the pubic arch, posteriorly by the coccyx and laterally by the ischiopubic rami
Term
clinical perineum
Definition
region between vagina and anus
Term
episiotomy
Definition
incision made prior to delivery to prevent tearing into anus
Term
mammary glands position
Definition
-overlies pectoralis major
-extends from rib 2 to rib 6
Term
mammary glands structure
Definition
-lobes: glandular tissue separated by adipose tissue
-lobules: alveoli- glandular sacs which secrete milk, suspensory ligaments of cooper- CT which support breast, lactiferous duck- carries milk from gland to nipple
-nipple: areolar (dark pigmented region) approx. level T4
-lymphatic drainage: 75% drains toward axillary nodes
