Reproductive System Flashcards
Gonads
Where gametes are made
Genitalia
internal and external reproductive organs
Spermatogenesis
Takes place in gonads (testes) to produce sperm and testosterone
Testicular Thermoregulation
Cremaster muscle (draws testes to body) and Dartos muscle (wrinkles scrotal)
Seminiferous tubules
Separated by septum and produce spermatozoa
Cowper’s Gland
produces pre-ejaculation that lubricates the urethra and neutralizes remaining acidic urine
SEVEN UP
Seminiferous tubules
Epididymis
Vas deferens
Ejaculatory ducts
Urethra
Penis
Sperm vs. Semen
Sperm: short for spermatozoa, haploid gamete that fertilizes eggs
Semen: alkaline nutrient filled liquid, carries sperm through reproductive tract
Azoosperma
Semen containing no sperm
Epidiymis
sperm mature
Leydig cells
produce androgens
Sertoli cells
support spermatogenesis
Bulbourethal glands
produce pre-ejaculate
Seminal vesicles
secrete nutrients into seminal fluid
seminiferous tubules
site of spermatogenesis
Female internal reproductive organs
Fallopian tube, uterus, cervix, vagina, ovary
Female external reproductive organs
Vulva: labia minora, labia majora, clitoris, and vagina
Oogenesis
Production of female gametes
Ovaries produce
Estrogen and progesterone
Layers of uterus
Inner: endometrium
Middle: Myometrium
Outer: Perimetrium
Order of becoming motile sperm
Stem cell spermatogonia primary secondary spermatids spermatozoa
Spermatogenesis occurs in the …
Seminiferous tubules
Until puberty, what stage is arrested in oogenesis?
Prophase I
Order of development of female gamete
Primordial germ cells, oogonia, primary, secondary, arrest in metaphase II, fertilized ovum
