Ch.2 Flashcards
penis
ejaculate semen and transport urine from inside the body to outside
penile glans
sexually sensitive area of penis, the tip.
Corona
raised ridge at the base of the penile glans where the tip joins the shaft.
frenulum
area of tissue at the base of the underside of the penile glans, is typically reported to be the most sexually sensitive area of the glans
penile shaft
loose to allow for expansion during erection
foreskin
skin covering penile glans
corpora cavernosa
2 tubes on the top side of the penis
corpus spongiosum
third tube that runs along the underside of the penis
urethra
tube that runs the length of the penis and into the body to carry semen/ urine from the inside to outside of body
scrotum
pouch of 2 layers of skin that hangs below and behind the penis
spermatic cords
2 small muscles move the scrotum and testicles up and down depending on different situations.
testicles
float freely, one in each sac, within the scrotum
gonads
testicles are glands which produce cells for reproduction
testosterone
testicles primary function to manufacture sperm cells and secrete this male sex hormone.
seminiferous tubules
each testicle composed of these seed forming tubes
epididymis
where sperm cells migrate in an immature state. long, narrow structure attached to the back of each testicle. where sperm cells mature and wait to be ejaculated.
vas deferens
each epididymis is attached to this. a tube through which mature sperm cells travel to the man’s internal reproductive system where they are mixed with semen and ejaculated through the penis.
semen
white/yellowish fluid composed of water, salt and fructose sugars designed to nourish and sustain sperm cells from their journey from the vagina
seminal vesicles
small glands located in the upper internal end of each vas deferens
ejaculatory duct
directs semen into the urethra
prostate gland
adds prostatic fluid to semen
prostatitis
bacterial infection of the prostate gland
urethral bulb
portion of the urethra surrounded by the prostate gland.
Cowper’s glands
one on each side of the urethra, adds a small amount of fluid to the semen. secretes fluid into the urethra and out through the penis before ejeaculation
pre-ejaculate
during sexual arousal a small amount of clear, thick, slippery fluid from the Cowper’s glands may appear at the urethral opening at the tip of the penis.
vulva
external genitals are refererred to as this
mons veneris
top of pubic bone, only part of female sexual anatomy easily seen from the front
labia majora
folds of skin and fatty tissue that extend from the mons past both sides of the vulva. protect the more sensitive and delicate genital structures underneath them.
labia minora
inside the labia majora. smooth, hairless.
clitoral glands
the top of the labia minora, the tip of teh clitoris and the part that can be seen
clitoral hood
covers the clitoris
hymen
thin layer of tissue that partly covers the vaginal opening
hymenorrhaphy
surgically restores the hymen in an intact appearing state
perineum
area of skin between the vaginal opening and the anus
episiotomy
perineum may be cut during childbirth
areola
darker skin around each nipple
vagina
flexible muscular canal or tube
g spot
Grafenberg spot. area of tissue located a third of the way in from the opening of the vagina in the anterior vaginal wall
cervix
narrow bottom end of the uterus
os
passageway through the cervix.
pap test
medical test to check the cervix for abnormal test. vagina is held open with a speculum and a few cells are swabbed from the cervix
HPV
primary cause of cervical cancer. sexually transmitted
uterus
the womb. where a fertilized egg implants itself
endometrium
lining of the uterus. builds up an extra layer of blood and tissue preparing to receive a fertilized egg
endometriosis
cells and tissue from endometrium migrate to outside the uterus and begin to grow in abdominal cavity, ovaries as well as other parts of the inside of the body
fallopian tubes
top part of the uterus, extend from the uterus up to the ovaries. release eggs
ovum
egg
ectopic pregnancy
growth of a fertilized egg outside the uterus
ovaries
gonads. produce eggs
estrogen and progesterone
female hormones. produced by ovaries.
ovarian cysts
small fluid filled sacs that grow on one of the ovaries
menarche
onset of menstrual cycle
ovulation
releasing of a mature ovum about once each month
follicle-stimulating hormone(FSH)
causes an ovum in one of the ovaries to mature
luteinizing hormone (LH)
ovulation occurs, the egg leaves the ovary and enters the fallopian tube
amenorrhea
absence of a period . haven’t started period by 16, or lost period.
dysmenorrhea
painful periods
abnormal uterine bleeding
abnormal bleeding. very heavy, unusually long, periods too close together, bleeding between periods
toxic shock syndrome
