Chapter 14 The Reproductive Systems A&P Flashcards
are the organs of reproduction and their associated structures
genitalia
are reproductive organs located outside of the body cavity
external genitalia
are reproductive organs protected within the body
internal genitalia
is the external surface region in both males and females between the pubic symphysis and coccyx
perineum
extends from the scrotum to the area around the anus
male perineum
extends from the pubic symphysis to the area around the anus
female perineum
are the penis and the scrotum, which contain two testicles
external male genitalia
include the remaining structures of the male reproductive system
internal male genitalia
is the sac-like structure that surrounds, protects, and supports the testicles
scrotum
also known as testes, are the two small, egg-shaped glands to produce the sperm
testicles
sperm are formed within these of each testicle
seminferous tubules
is a coiled tube at the upper part of each testicle. tube runs down the length of the testicle
epididymis
extends upward from the epididymis and is attached to each testicle
spermatic cord
also known as spermatozoa, are the male gametes
sperm
is the process of sperm formation
spermatogenesis
means capable of spontaneous motion
motile
is the male sex organ that transports sperm into the female vagina
penis
during sexual stimulation, the erectile tissue fills with blood under high pressure. this causes the swelling, hardness, and stiffness known as a
erection
mean relating to the penis
penile, phallic
also known as the head of the penis, is the sensitive region located at the tip of the penis
glans penis
also known as the prepuce, is a retractable double-layer fold of skin and mucous membrane that covers and protects the glans penis
foreskin
also known as the ductus deferens, are the long, narrow continuations of each epididymis
vas deferens
are glands that secrete a thick, yellow substance to nourish the sperm cells
seminal vesicles
begins at the vas deferens, pass through the prostate gland and empties into the urethra
ejaculatory duct
lies under the bladder and surrounds the urethra in the region where the vas deferens enters the urethra
prostate gland
means ability to move
motility
also known as the cowper’s glands, are located just below the prostate gland. one of these glands is located on either side of the urethra, and they open into the urethra
bulbourethral glands
helps flush out any residual urine or foreign matter in the urethra
pre-ejaculate
passes through the penis to the outside of the body
urethra
is a physician who specializes in diagnosing and treating diseases and disorders of the genitourinary system of males and the urinary system of females
urologist
refers to both the genital and urinary organs
genitourinary
are located posterior to the mons pubis
external female genitalia
a rounded, fleshy prominence located over the pubic symphysis
mons pubis
external reproductive structures in females are collectively known as
vulva or the pudendum
are the vaginal lips that protect the other external genitalia and the urethral meatus
labia majora and labia minora
is the external opening of the urethra
urethral meatus
is an organ of sensitive, erectile tissue located anterior to the urethral meatus and the vaginal orifice
clitoris
produce a mucus secretion to lubricate the vagina
bartholin’s glands
is the exterior opening to the vagina
vaginal orifice
is a mucous membrane that partially covers the vaginal orifice and can be torn either during the first instance of intercourse or other activity
hymen
are made up of fat, connective tissue, and the mammary glands
breasts
also known as lactiferous glands, are the milk-producing glands that develop during puberty
mammary glands
also known as milk ducts, carry milk from the mammary glands to the nipple
lactiferous ducts
opening breast milk flows through
nipple
dark-pigmented area around the nipple
areola
are a pair of small, almond-shaped organs located in the lower abdomen, one on either side of the uterus
ovaries
is a fluid-filled sac containing a single ovum (egg).
follicle
also known as eggs, are the female gametes
ova
which are also known as uterine tubes, these tubes extend from the upper end of the uterus to a point near but not attached to an ovary
fallopian tube
is the funnel-shaped opening into the fallopian tube near the ovary
infundibulum
are the fringed, finger-like extensions of this opening. role is to catch the mature ovum when it leaves the ovary
fimbriae
formerly known as the womb, is a pear-shaped organ with muscular walls and mucous membrane lining filled with a rich supply of blood vessels
