reproductive organs Flashcards
what is the pelvic cavity
cavity between the line that links sacrum to pubic tubercle and the sling of muscles that comprise the perineum
what is the perineum
muscle sling in the pelvic cavity
boundaries of the pelvic cavity
anterior: pubic symphysis
posterior: coccyx
lateral: ischial tuberosities
anterolateral: ischiopubic ramus
posterolateral: sacrotuberous ligament
what are the divisions of the perineum
anal triangle and urogenital triangle
what portion of the perineum is the anal triangle, how many openings, and purpose
-posterior portion
-one opening - anal canal
-maintains the angle of the rectum to maintain bowel movements
what portion of perineum is the urogenital triangle, how many openings
-anterior portion
-1 opening males - urethra, 2 openings female - urethra and vaginal canal
what is the pelvic diaphragm
levator ani and coccygeal muscles
function of levator ani
lifts pelvic floor
what is the perineal membrane and its function
-fascial structure attached to pubic arch
-provides structural supports and attachment for genitalia and muscles
what is the trigone made up of
2 openings of ureters and internal urethral orifice
what do the testes produce
immature sperm
what structure brings sperm to maturity
epididymus
what does the ductus deferens join
seminal vesicle
what forms the ejaculatory duct
ductus deferens and seminal vesicle
what does the seminal vesicle produce and function
alkaline secretion to protect sperm
what structure inferior to the bladder does the urethra pass through
prostate gland
what does the prostate gland produce and function
secretion that contributes to sperm mobility and viability
what are the 3 cylinders of erectile tissue
2 corpora canvernosa
1 corpus spongiosum
which cylinder of the penis has spaces that fills with blood
corpora cavernosa
what does the corpus spongiosum contain and what does it form at the end and base
-contains spongy urethra
-forms glans at the end and bulb at the base
path of sperm
testicle
epididymus
ductus deferens
ampulla of ductus deferens
seminal vesicle
ejaculatory duct
prostatic urethra
where are the prostate, bladder, seminal vesicle, and rectum relative to eachother
prostate is inferior to bladder
seminal vesicle is posterior to bladder and anterior ot rectum
rectum is posterior to all
where are the uterus, bladder, ovaries, and rectum relative to each other
ovaries are posterior to uterus
uterus is between bladder (anterior) and rectum (posterior)
what does the egg go through in order from ovary
ovary
fimbrae
infundibulum
ampulla
isthmus
uterus
what structures hold the ovaries in place
mesovarium
suspensory ligament
ovarian ligament
what does the broad ligament do
limits movement of uterus
