Ch. 14 Reproductive System Flashcards
the organs of reproduction and their associated structures
genitalia
external surface region in both males and females btw the pubic symphysis and the coccyx
perineum
saclike structure that surrounds, protects, and supports the testicles
scrotum
two small egg-shaped glands that produce the sperm
testicles
where sperm is formed within each testicle
seminiferous tubules
coiled tube at the upper part of each testicle
epididymis
extends upward from the epididymis and is attached to each testicle, contains a vas deferens plus arteries, veins, nerves, and lymphatic vessels
spermatic cord
the long narrow continuations of each epididymis
vas deferens
glands that secrete a thick, yellow substance to nourish the sperm cells
seminal vesicles
lies under the bladder and surrounds the end of the urethra in the region where the vas deferens enters the urethra
prostate gland
glands that secrete a fluid known as pre-ejaculate that helps flush out any residual urine or foreign matter in the urethra as well as lubricates the urethra
bulbourethral glands
the process of sperm formation
spermatogenesis
inflammation of the glans penis that is usually caused by poor hygiene in men who have not had the foreskin removed
balanitis
narrowing of the opening of the foreskin so it cannot be retracted to expose the glans penis
philmosis
form of sexual dysfunction in which the penis is bent or curved during an erection
Peyronie’s disease
male menopause caused y the decrease of the male hormone testosterone
andropause
absence of one or both testicles
anorchism
developmental defect in which one or both of the testicles fail to descend into their normal position
cryptorchidism
fluid-filled sac in the scrotum along the spermatic cord leading form the testicles
hydrocele
painful erection that lasts 4 hours or more but is not accompanied by sexual excitement
priapism
cyst that develops in the epididymis and is filled with a milky fluid containing sperm
spermatocele
most common cancer in american males btw 15-34 years
testicular cancer
sharp pain in the scrotum caused by twisting of the vas deferens and blood vessels leading into the testicle
testicular torsion
a knot of varicose veins in one side of the scrotum
varicocele
absence of sperm in the semen
azoospermia
presence of blood in the seminal fluid
hemospermia
the surgical removal of one or both testicles
orchidectomy
endoscopic surgery to move an undescended testicle into its normal position in the scrotum
orchiopexy
the removal of a portion of an enlarged vein to relieve a varicocele
varicocelectomy
surgical removal or destruction of both testicles
castration
procedure performed as an attempt to restore fertility to a vasectomized male
vasovasostomy
most commonly reported STD in the US, causes damage to reproductive organs in females, and causes urethritis in male
chlamydia
condition in which there is an abnormal overgrowth of certain bacteria in the vagina
bacterial vaginosis
rounded fleshy prominence located over the pubic symphysis in females
mons pubis
collective name of the labia, clitoris, bartholins glands, and vaginal orifice
vulva
vaginal lips
labia majora and labia minora
organ of sensitive erectile tissue located anterior to the urethral meatus and the vaginal orifice
clitoris
produce a muscus secreation to lubricate teh vagina
Bartholin’s glands
the mucous membrane that partially covers the vaginal orifice before she has had intercourse
hymen
milk producing glands that develop during puberty
mammary glands
carry milk from the mammary glands to the nipple
lactiferous ducts
fluid-filled sac containing a single ovum
follicle
female gametes (eggs)
ova
tubes that extend from the upper end of the uterus to a point near, but not attached to, an ovary
fallopian tubes
funnel-like opening into the fallopian tube near the ovary
infundibulum
fringed, finger-like extensions of the infundibulum, whose role is to catch the mature ovum when it leaves the ovary
fimbriae
pear-shaped organ with muscular walls and a mucous membrane with a rich supply of blood vessels
uterus
the bulging rounded part of the uterus above the entrance of the fallopian tubes
fundus
body of the uterus
corpus
lower narrow portion of the uterus that extends into the vagina
cervix
