Reproductive System - E3 Flashcards
Perineum
diamond-shaped area containing external genitalia plus anus and external urethral orifice
Primary sex organs
gonads - testes and ovaries produce gametes (sex cells) - sperm and ova
Accessory sex organs
Ducts - store and transport
Glands & Organs - mucus production, viscosity levels
Male reproductive system
scrotum
testes
penis
accessory sex organs
Scrotum
“bag”
out pocketing of abdominal wall
helps lower temp. for sperm production
Dartos & Cremaster muscles
dartos - smooth muscle (wrinkling)
cremaster - skeletal muscle (can pull up scrotum)
both allow temp. control
Testes
paired oval glands
develop in abdominal cavity but descend into scrotum
covered by tunica albuginea
subdivided into lobules
each lobule divided into 1-3 seminiferous tubules
Tunica albuginea
dense, white fibrous c.t.
What are leydig cells
interstitial cells that make testosterone in the testes
Duct system of male reproductive system
- seminiferous tubules
- ductus epididymis
- ductus (vas) deferens
- ejaculatory duct
- urethra
Tissue component and function of:
- ductus epididymis
- vas deferens
pseudostratified columnar epithelia
- sperm maturation; coiled
- peristalsis; not coiled
Semen
fluid + sperm
Accessory sex glands
produce enzymes/buffers for female receptivity
seminal vesicles (2)
prostate
bulbourethral (2)
Female reproductive system
- Ovaries
- Fallopian tubes
- Uterus
- Vagina
- Vulva
Ovaries
paired, flat ovals
produce ova and hormones
also has tunica albuginea
Follicles
ovum + supporting cells
located in cortex of ovaries
Uterus
womb
“metri”
“hyster-“
Layers of uterus
- perimetrium - serosa; visceral peritoneum
- myometrium - smooth muscle
- endometrium - simple col. epi.; c.t.; inner layer shed each month, outer retained
Vagina
birth canal
tubular, fibromuscular organ
mucosa lined with strat. squamous epi.
rugae allow for expansion and stimulation
Clitoris
erectile tissue w/prepuce
Labia majora vs minora
Majora - lateral fold, fat, hair
Minora - medial enclosed vestibule, no fat, no hair
Alternate names for uterine tubes
Fallopian tubes
Oviducts
Uterine tubes
not directly attached to ovary
infundibulum w/fimbriae surrounds ovary
How does the uterine tubes transport ova to the uterus?
- Cilia lining the tubes - inward current
2. Smooth muscle - peristalsis
How do the testes and ovaries compare?
- Both covered in tunica albuginea
- Both gonads
- both paired
- both produce gametes
- both develop internally, retroperitoneal
