reproductive Flashcards
biological male features
-has a penis (hehe) and scrotum
-XY chromosomes
biological female features
-has a vulva
-XX chromosomes
gonads male vs. female
reproductive organs that produce gametes and hormones
M:testes
F: ovaries
gametes M vs. F
reproductive cells
M: sperm
F: oocyte
reproductive tract M vs F
ducts that receive, store and transports gametes
m: epididymis, ductus, deferens and urethra
f: uterine tubes, uterus, cervix and vagina
external genitalia M vs F
visible structures
m: scrotum and penis
f: vulva and breast
accessory glands/ organs M vs F
secret fluids into reproductive tract
m: prostate, seminal glands and bulbourethral glands
f: urethral glands
ovaries
-small paired intraperitoneal organs that produce oocytes
-follicles and interstitial cells secret estrogen (sexual and reproductive development) and progesterone (maintains uterus during pregnancy)
- stabilize by the mesovarium, ovarian ligament and suspensory ligament
uterine tubes (fallopian tube)
-mucus membrane that has cilited and non-ciliated simple columnar cells+smooth m.
-nourishes oocyte and brings it to uterus
uterus
-Provides:
*Protection & nutritional support for the embryo/fetus
*A means to remove waste produced by embryo/ fetus
-stabilized by broad ligament and 3 pairs of suspensory ligaments
skeletal m. and facia of pelvic floor provide support too
-intraperitoneal
uterine wall
- endometrium (glandular layer)
- perimetrium (incomplete serosal layer)
- myometrium (smooth m.)
- basal layer (connects endometrium to myometrium)
- functional layer (simple columnar ET and uterine glands)- changes in thickness during uterine cycle
ovarian process
- oogenesis (production of oocytes)
- ovarian cycle (maturation of oocytes)
- uterine cycle (prepares uterus for implantation of a fertilized oocyte)
vaginas (functions and epithelial tissue)
stratified squamous
-passage way for period blood to leave
-receive the penis (ew) and holds sperm
-forms lower portion of birth canal
testes
-hangs within scrotum
-spermatic cords(ductus deferens,
associated blood vessels, nerves, & lymphatic vessels)
seminiferous tubule has… (internal structure of testes)
germ cells- produce sperm
-sperm will then travel through this tube to the epididymis and then the ductus deferens
key cells of testes
interstitial (endocrine function) endocrine cells- produces testosterone)
nurse cells (exocrine function)- stimulated by T and follicle stimulation hormone to promote sperm maturation
what is the function of testosterone
sperm development and muscle growth
epididymis (internal structure of testes)
lines with pseudostratified columnar ET and long cilia
-monitors fluid composition of ST
-recycles damaged sperm
-stores sperm
vas (ductus) deferens
smooth m. lined with pseudostratified columnar ET
- can store sperm for several months
-joins with excretory duct of seminal gland
-sperm becomes motile when mixed with secretions of seminal glands
seminal glands
-60% of semen volume
-discharged into ductus deferens during ejaculation
-makes sperm motile and provides nutrients
what is semen
a mixture of secretions from different glands and sperm
prostate gland
-simple columnar epithelium
-produces prostatic fluid (prevents sperm coagulation in vagina and produce an antibiotic)
bulbo-urethral gland
-simple cuboidal/columnar epithelium
-secretes alkaline mucus that neutralizes urinary acids
