Lecture 1 - Pathophysiology Flashcards
True or False. Females produce testosterone
True
True or False. Estrogen and progesterone has responsibility in pregnancy.
True
What regulates the temperature of sperm?
Scrotum
Menstrual flow = Sloughing of the _______
Endometrium
True or False. Menopause is the absence is eggs
False
Female reproductive organ
Ovary
Female reproductive cell
Ovum
Male reproductive organ
Testicle
Male reproductive cell
Sperm
Role of FSH in females
Regulates ovarian follicle development, stimulates ovarian estrogen production
Role of FSH in males
Stimulates seminiferous tubule development tubule development, regulates spermatogenesis
Role of LH in females
Mediates ovulation and maintenance of the corpus luteum
Role of LH in males
Induces Leydig cell testosterone synthesis and secretion
Made up of erectile tissue (corpus cavernosum)
Penis
Connects urinary bladder to external genitalia
Urethra
External sac that contains testes and epididymis
Scrotum
Regulates temperature (89.6 F)
Scrotum
Site of spermatogenesis and sex hormone production
Testes
Ducts in the testes that store sperm during the maturation process
Epididymis
Connects epididymis to urethra
Vas deferens
Gland that surrounds the urethra; located below the bladder in males
Prostate
Secretes a milky fluid that contributes to the bulk of semen
Prostate
Gland located on the base of the male bladder
Seminal vesicle
Empty secretions (along with sperm) into the ejaculatory duct during emission and ejaculation; secretions add to the volume of semen
Seminal vesicle
Principle hormone of the testes
Testosterone
Where is testosterone synthesized?
From cholesterol in the Leydig cells
Movement of semen into the urethra
Emission
Propulsion of semen from urethra at time of orgasm
Ejaculation
Fluid that is ejaculated at the time of orgasm
Semen
Average volume of sperm per ejaculation
2.5-3.5 mL
1 mL = ________ sperm
100 million
Inferior region of the birth canal
Vagina
Passageway for sloughed endometrium (menstruation)
Vagina
Receptacle for the penis during sexual intercourse
Vagina
Outlet that projects into the vagina
Cervix
Hollow organ that functions to receive and nourish a fertilized oocyte until birth
Uterus (womb)
Extend from the ovaries to the uterus
Fallopian tubes (uterine tubes)
Finger-like projections on the fallopian tubes
Fimbriae
Help move the oocyte down the uterine cavity
Fimbriae
Sources of estrogen in pre-menopause
ovaries, adrenal gland, adipose tissue
Sources of estrogen in post-menopause
adrenal gland, adipose tissue
Hormone secreted by the ovaries
Progesterone
Definition of puberty
Endocrine and gametogenic functions of the gonads have developed to the point where reproduction is possible
When does puberty occur in females?
8-13 yo
When does puberty occur in males?
9-14 yo
Breast development
Thelarche
Pubic and axillary hair development
Pubarche (adrenarche)
First menstrual period
Menarche
Secretion of adrenal androgens; development of secondary sex hormones
Adrenarche
LH is responsible for:
Leydig cell testosterone synthesis
