scrotum | a pouch of skin that houses the testes. |
penis | external cylinder-like shaped organ that moves urine and semen out of the body. |
epididymis | coiled tube located superior to each teste, responsible for maturation of sperm cells |
vas deferens | connects the epididymis to the urethra |
seminal vesicles | sac-like organs that secrete seminal fluid. this fluid stimulates 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 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, connects distally to uterus. receives egg during ovulation |
uterus | hollow muscular organ, lies low in the pelvic cavity. receives fertilized egg, which implants into uterine wall for fetal development. in a nonpregnant female, the uterine lining sloughs off monthly, causing menstruation. |
cervix | lower portion of the uterus, which created a barrier between the uterus and the vagina and 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, forms a hood over the clitoris. |
clitoris | highly sensitive female erectile tissue located anterior to the urethra. |
perineum | area between the vagina and the anus |
estrogen | group of female sex hormones |
progesterone | hormone secreted by ovaries |
estradiol | most abundant and biologically active female hormone. |
