CCMA Mod 2 Reproductive System

testes

produce sperm and testosterone; located below the pelvic cavity on the outside of the body, within the scrotum

scrotum

a pouch of skin that houses the testes

penis

external cylinder shaped organ that moves urine and semen out of the body

epididymis

coiled tube located superior to each testis; responsible for maturation of sperm cells

vas deferens

connects the epididymis to the urethra

seminal vesicles

sac like organs that secrete seminal fluid that stimulate muscle contractions in the female reproductive organs to aid in propelling sperm forward

prostate gland

surrounds the proximal urethra; contracts during ejaculation to aid in forward movement of sperm; secretes fluid that protects sperm within the vagina

bulbourethral glands (cowper’s glands)

inferior to the prostate gland; secrete fluid to lubricate the end of the penis to prepare for intercourse

androgens

group of male sex hormones

testosterone

most abundant and biologically active of male sex hormones

ovaries

pair of oval shaped organs located within the pelvic cavity; produce ova, estrogen, and progesterone

fallopian tubes

muscular tubes with proximal opening near each ovary; connect distally to uterus; receive egg during ovulation

uterus

hollow muscular organ, lies low in pelvic cavity; receives fertilized egg, which implants into wall for fetal development

cervix

lower portion of the uterus creating a barrier between the uterus and vagina, dilates during childbirth

vagina

muscular tube extending from the uterus to the outside of the body; expands during intercourse and childbirth

labia majora

folds of skin and adipose tissue that protect other external genitalia

labia minora

folds of skin within the labia majora, pinkish in color due to high blood circulation; form a hood over the clitoris

clitoris

highly sensitive erectile tissue located anterior to the urethra

perineum

area between the vagina and anus

estrogen

group of sex hormones

progesterone

hormone secreted by ovaries

estradiol

most abundant and biologically active female hormone
