Anatomy 1 Exam 3 Flashcards
Sex glands that produce gametes (sex cells)
Gonads
pendulous pouch which ultimately houses male gonadsequipped with cremasteric (muscle) reflex to ensure proper temperature for sperm production
Scrotum
Originally within abdominal cavity and will descend into the scrotummale gonads
Testes
where sperm first producethousands of minute tubes (tube-like) passageways
seminiferous tubules
beginning or production of spermprimary function of testes
spermatogenesis
Testes hormone production
testosterone
female sex glands
ovaries
sperm shift/pass through passageways for sperm located between testes to urethra(between bladder and outside of body
spermatic ducts
entirely in scrotumfirst part of spermatic duct where sperms are shift
epididymissperm spend average 2 to 3 day life span (nursery)
2nd part of spermatic duct where sperm will past between scrotum & prostate glandportion is ligated (tied off) in vasectomy
Ductus deferens(vas deferens or seminal duct)
located wholly/entirely within prostate gland
ejaculatory ducts
sperm mature & gain mobility in epididymiswhere sperm spend the majority of 2 to 3 day life span (nursery)
spermatic ductspassageway for sperm from testes to urethra
located between prostate gland and outside of body (male)
urethra
part of urethra that passes through prostate gland
prostatic urethra
part of the urethra in men that passes through the penis
penile urethra
path for urine from bladder to outside of the body
urethra
located at the base of bladder directly above rectumsingle walnut size gland
prostate gland (location)
adds a substance highly alkaline in pH to neutralize acidity left over in urethra from previous urination
Prostate gland (function)
outside of body along with scrotummakeup the external genitalia of male
penis
cavernous body of male penis
corpus cavernosum
sponge body only with male penis
corpus spongiosum
last structure sperms passserves as male organ of intercourse
penis
female gonads located in abdominal cavity
ovaries
tiny sac-like structure within ovaries each contain egg (female sex cell) in a different stage of maturity
graafian follicles
just after it released its mature egg means empty sac
corpus luteum(yellow body)
beginning or production of ova (eggs/female sex cells)
Oogenesis
produce by ovaries to prepare woman’s body for pregnancy
progesterone
responsible for development of secondarily sex characteristics in womenie: pubic hair, breast enlargement, sexually mature at 30
estrogen
the release of a mature ovum once every 28 daysprocess stops with the onset of menopause (stopping of sensation of ovulation & menstruation
ovulation
oviducts - passage ways for eggs
uterine “fallopian” tubes
2 tapered tubes located between ovaries and uterus but not attached to ovaries
uterine “fallopian” tubes (location)
tapered tubes/funnel shape, widest where eggs enter them
uterine “fallopian” tubes (structure)
path for ovum from ovary to uterusunion of single egg & sperm fertilization
uterine “fallopian” tubes (function)
womb inside abdominal cavity
uterus
- fundus2. body3. cervix
Gross structure of Uterus
upperdome shape portion of uterus
fundus
largest part of uterus
body
lower constricted neck like portion of uterus
cervix
- endometrium2. myometrium3. perimetrium
Microscopic structure of Uterus
innermost layer uterushighly vascular (blood vessels)discharge during menstruation
endometrium
discharge of endometrium layer of woman uterus - average 14 days after ovulation
menstruation
muscle layer of uterus that causes labor pains
myometrium
highly elastic allows to expand 8 to 14 times during gestational pregnancy
perimetriumsafest place for child to be
usual site of implantation of fertilized egg on endometrium layerusual site of gestation (pregnancy) - 10 lunar months 280 days
uterus (function)
birth canal, acidic in pHfrom cervix to outside of bodyreceptor for penis
vaginalast part child pass during birth
external genitialia
vulva
2 large vertical folds of tissue that mark lateral boundaries of vulva
labia majora
2 smaller vertical fold of tissue located just inferior/inside the labia majora
labia minora
space between labia minoracontains urethral & vaginal orifices/openings
vestibule
most superior within vestibuleopening of urethral that convey urinal from bladder to outside of body
urethral orifices
most inferior within vestibuleopening of vagina or birth canal to outside of body
vaginal orifices
why vagina has acidic pH (yeast infection prone)
by location, opening of birth canal lye inferior to urethra, urine influences the vagina beneath it
most superior structure of vulva, highly sensitive mass of tissue
clitoris
mammary glands located in pectoral (chest) region
breasts
milk secreting cells embedded within adipose (fatty) tissue
breasts (structure)
produce and secrete breast milk (colostrum-first mother’s milk secreted following child birth)
breasts (function)
single organ that develops upon implantation of a fertilized egg onto the endometrium layer of the uterus
placenta(afterbirth)
