Exam 7 51-116 (Finish) Flashcards
Slide 51, 52
Female external genitalia
The ___refers to the external genitalia of the female
vulva (pudendum)
Vulva includes?
Mons pubis
Labia majora
Labia minora
CLitoris
Vestibule
Paraurethral (Skene’s) glands
Greater vestibular (Bartholin’s) glands
Corpus spongiosum (bulb of the vestibule)
Corpus cavernosum
adipose tissue, cushions pubic symphysis
Mons pubis
Covered by pubic hair, composed of adipose tissue, sebaceous glands, sudoriferous glands
Homologous to the scrotum
Labia majora
Devoid of pubic hair and fat, few sudoriferous glands
Contains many sebaceous glands
Homologous to spongy (penile) urethra
Labia minora
Contains erectile tissue (corpora cavernosa) and numerous blood vessels and nerves
Prepuce- layer of skin formed at the point where labia minora unite, covers body of clitoris
Clitoris
Exposed portion of clitoris is called the
glans clitoris
hymen
vaginal orifice
external urethral orifice
openings of ducts of several glands
comprise the?
Vestibule
Glands of the vestibule?
Paraurethral (Skene’s) glands
Greater vestibular (Bartholin’s) glands
lateral to urethral orifice
secrete mucous
embedded in the wall of the urethra.
Paraurethral (Skene’s) glands
lateral to vaginal orifice
produce mucous during sexual arousal to provide lubrication
Greater vestibular (Bartholin’s) glands
Has two masses of erectile tissue that engorge during sexual arousal to narrow the vaginal orifice applying pressure to the penis during intercourse
Corpus spongiosum (Bulb of the vestibule)
Erectile and very sensitive tissue that fill with blood during sexual arousal as well
Corpus Cavernosum
Distal portion of this is the clitoris
Corpus Cavernosum
Slide 56-59
External genitalia
Diamond shaped area medial to thighs and buttocks
Both males and females
Contains external genitalia and anus
Perineum
Anterior aspect of perineum?
pubic symphysis
Lateral aspect of perineum?
Ischial tuberosity
A transverse line drawn from one tuberosity to the other divides this (perineum) diamond into the
Urogenital triangle
Anal triangle
posterior aspect of perinuem?
coccyx

Mammary glands lie anterior to the pectoralis major and _____ muscles
serratus anterior
Each breast is a hemispheric projection of variable size
series of closely spaced openings where milk emerges from
Lactiferous Ducts
Nipple- Each breast has one pigmented projection
Circular pigmented skin surrounding nipple
Areola
Areola appears rough as it contains
modified sebaceous glands
run between breast skin and fascia
Cooper’s Ligaments
Become looser with excess age or strain (ie:jogging)
Cooper’s Ligaments
Mammary gland- each breast contains __(#) gland?
Lobes (compartments)- each gland contains ___(#)?
one
15-20
Each lobe has several lobules… what’s found within lobules that secrete milk?
alveoli
synthesis, secretion, and ejection of milk
Lactation
Functions of mammary glands
Milk production stimulated by?
Milk ejection stimulated by?
prolactin
oxytocin
Slide 66
Nipples
Slide 67 for male/female comparison
yup
Nonpregnant females experience cyclical changes in the ovaries and uterus. Each cycle takes approximately?
one month (24-36 days)
The cycle involves ___ and preparation by the uterus to receive a fertilized ovum
oogenesis
Hormones from the hypothalamus, anterior pituitary and ovaries control these processes
Two cycles of female reproductive cycles?
Ovarian cycle
Uterine cycle
includes changes that occur during and after maturation of the oocyte
Ovarian cycle
involves changes in the endometrium that prepare it for implantation of the developing embryo
If fertilization does not occur, the ovarian hormones recede and cause sloughing of the stratum functionalis
Uterine cycle
Released from the hypothalamus
Controls both the ovarian and uterine cycles
Gonadotropin-releasing hormone (GnRH)
Stimulates release of LH and FSH
Stimulates ovarian follicles to produce estrogen
Gonadotropin-releasing hormone (GnRH)
Initiates follicular growth
Follicle Stimulating Hormone
Androgens (made by ___) taken up by the granulosa cells and turned into estrogen (under influence of___)
LH
FSH
Stimulates further development of ovarian follicles
Stimulates theca cells to produce androgens
Luteinizing Hormone
Luteinizing Hormone Stimulates ___ cells to produce androgens
theca
triggers ovulation (mid-cycle)
Luteinizing Hormone
triggers ovulation (mid-cycle)
Then forms the corpus luteum (which then secrete other hormones)
Luteinizing Hormone
After being triggered by LH, Corpus luteum then produces and secretes
Estrogen
Progesterone
Relaxin*-Very small amounts produced unless fertilization occurs
Inhibin*-Very small amounts produced unless fertilization occurs
What hormone promotes development and maintenance of:
Reproductive structures
Breasts
2° sex characteristics
Estrogen
Distribution of adipose tissue in breasts, abdomen, mons pubis, hips
Voice pitch
Broad pelvis
Pattern of hair growth (head and body)
2° sex characteristics
from estrogen
Increases protein anabolism
(Includes building of strong bones
Synergistic with hGH)
estrogen
Lower blood cholesterol
Thought to be the reason most women under 50 have lower risk of coronary artery disease compared to men
Estrogen
Moderate levels of estrogen in blood inhibit release of GnRH and secretion of FSH/LH
Estrogen
