holds the paired oval testies outside the abdominopelvic cavity, temperature is lower than body temp in order to produce vible sperm
elongated structure running up the posterolateral aspect of the testis and capping its superior aspect. Forms first portion of the duct system & provides site for immature sperm entering it from the testis to complete their maturation process
(sperm duct) arches superiorly from the epididymis, passes through the inguinal canal into the pelvic cavity and courses over the superior aspect of the urinary bladder.
CT sheath that encloses the vas deferens w/ blood vessels and nerves
duct in which the enlarged region that is formed by vas derens empties out in
contraction of the ejaculatory duct propels the sperm through the prostate to the prostatic urethra
prostatic urethra empties into →membranous urethra, which empties into→spongy urethra which runs lenth of the penis to the body exterior.
the liquid medium in which sperm leave the body
sperm plus seminal fluid
produce 70% of seminal fluid, lie at the posterior wall of the urinary bladder to the terminus of the ductus deferens/vasdeferens
encircles the urethra just inferior to the bladder. It secretes a milky fluid into ureth, which plays role in activating sperm.
are tiny, pea-shaped glands inferior to the prostate. They produce thick, clear, alkaline mucus that drains into the membranous urethra, this secretion neutralizes traces of acidic urine in the urethra just prior to ejaculation
part of the external genitalia of the male along w/ the scrotal sac, is the copulatory organ of the male
enlarged tip of the penis
circular fold of skin that forms from the skin covering the penis that is loosely applied and reflects downward
penis becomes rigid and enlarged so that it may more adequately serve as a penetrating device
paired dorsal cylinders
surrounds the penile urethra
coiled sperm-folding factories
another set of tubules at the posterior of the testis that sperm is emptied to
lie between seminiferous tubules and are softly padded with CT & produce testosterone.
(external genitalia) consists of the mons pubis, the labia majora and minora, clitoris, urethral and vaginal orifices, hymen, and the greater vestibular glands
rounded fatty eminence overlying the pubic symphysis
two elongated, pigmented, haircovered skin folds that run inferiorly & posteriorly from mons and are homologous to the scrotum
two smaller hair-free folds that are enclosed by labia majora
region enclosed by labia minora that contains many structures-the clitoris, most anteriorly, followed by the urethral orifice and vginal orifice
diamond shaped region between the anterior end of the labial folds, the ischial tuberosities laterally and the anus posteriorly
small protruding structure, homologous to the penis. Composed of highly sensitive erectile tissue
thin fold of mucous membrane that partially closes the vaginal opening
Greater Vestibular Gland
pea-sized, mucus-secreting glands that lubricate the distal end of the vagina during coitus
serves as a copulatoy organ & birth canal & permits passage of the menstrual flow.
pear-shaped & is sutuated between the bladder and the rectum
Uterine body & fundus
body- major portion of the uterus
fundus-superior rounded region above the entrance of the uterine tubes
narrow end of the uterus that is directed inferiorly
thick mucosal lining of the uterus, has superficial fxnal layer that sloughs off periodically
sloughing-off process(28 days) in response to cyclic changes in the levels of ovarian hormones in women's blood that is accompanied by bleeding
(uterine) enter the superolateral region of uterus and extend laterally for about 4 in toward overies in the peritoneal cavity
fingerlike extensions of the distal ends of the fallopian tubes that are funnel-shaped.
event in which the developing egg has reached the stage of maturity and is ejected from the ovary
exist w/in breasts in both sexes, but normally have reproduction-related fxn in females.
FXN: to produce milk and nourish newborn indant
Location: lie anterior to the pectoreal muscles of thorax, attached to them by CT
pigmented area that surrounds nipple
centrally protruding structure on breast
internally each mammary gland consists of 15-25 lobes which radiate around nipple and are seperated by fibrous CT and adipose
smaller chambers within each lobe that contain glandular alveoli that produce milk during lactation
join to form an expanded storage chamber in which milk passes through
