prostate, paired seminal vesicles, and bulbourethral glands are all ___ __
accessory glands
encircles the urethra and secretes a milky fluid into the urethra, activating the sperm
prostate
produce 60% of the seminal fluid, which nourish the sperm or promote fertilizing capability each vesicle merges with the ductus deferens to form the ejaculatory duct
paired seminal vesicles
tiny pea shaped glands inferior to the prostate. produce thick, clear, alkaline mucus that drains into the membranous urethra to wash residual urine to protect sperm

seminiferous tubules
seminiferous tubules converge and empty into the __ ___ , which then enter the epididymus
rete testis
between the seminiferous tubules are __ cells , which produce testosterone
interstitial
primary reproductive organs for females
ovaries (female gonads)
exocrine function of ovaries are
to produce ova (eggs)
endocrine function of ovaries
produce estrogen and progesterone
rounded mound of adipose tissue that becomes covered with pubic hair at puberty
mons pubis
inferior and posterior of the mons pubis are 2 elongated , hair covered skin folds , the __ __ [homologous to scrotum]
labia major
smaller and hair free labia minor are enclosed by the labia major, which in turn enclose the____
vestibule
small protruding structure homologous to the penis. composed of highly sensitive erectile tissue
clitoris
outlet for urinary system
urethral orifice
vaginal orifice is flanked by the ___ ___ ___ (pea sized glands that secrete mucus for lubrication)
greater vestibular glands
approx. 10 cm long and serves as the copulatory organ and birth canal
vagina
pear shaped ___ lies btwn bladder and rectum. its narrow end is called the ___
uterus/ cervix
thick mucosal lining of the uterus that has a superficial fucntional layer that sloughs off during menstruation
endometrium
during menstruation, the ___ ___ becomes a new functional layer
basal layer (stratum basalis)
extend laterally approx 10 cm
uterine (fallopian) tubes
finger like projections at the distal ends of the fallopian tubes
fimbrae

retroperitoneal
the fold that encloses the uterine tubes and uterus and secures them to the lateral body walls is the ___ ___
broad ligament
___ anchors the uterus
mesometrium
___ anchors the uterine tubes
mesoalpinx
fibrous cords that run from the uterus to the labia majora
round ligaments
__ ligaments also help attach the uterus to the body
uterosacral
ovaries are supported medially by the ___ ligament
ovarian
ovaries supported laterally by the ___ ligaments and posteriorly by a fold of the broad ligament, the mesovarium
suspensory
glands found within breasts, in both sexes, but have reproductive related function in F
mammary
internally each mammary gland consists of 15-25 __ which radiate around the nipple and are separated by adipose tissue
lobes
within each lobe are even smaller chambers called ___, containing the glandular alveoli that produce milk lactation
lobules
alveoli of each lobule pass the milk into numerous ___ ducts
lactiferous ducts
lactiferous ducts join to form an expanded storage chamber known as ___ ___ as they approach the nipple; these open to the outside at the nipple
lactiferous sinuses
contains oil glands
labia minora
contains adipose tissue, oil glands, and pubic hair
labia majora
funnel shaped end of uterine tube that lies near the ovary but is open to the pelvic cavity
infundibulum
recieves and implants the fertilized egg and hosues the developing fetus during pregnancy and labor
uterus
carry eggs from the ovaries to the uterus. fertilization occurs here
uterine (fallopian) tubes
clitoris is homologous to male glans penis while labia major is to __
male scrotum
mammary gland structure that contains the alveoli that produce milk lactation
lobules
immature sperm cells are produced in ___ __ ; and mature in epididymis
seminiferous tubules;
pathway that sperm travels to leave reproductive tract
epididymis ductus deferens ampulla ejaculatory duct prostatic urethra membranous spongy
