CCMA CH 6 REVIEW (Body Systems - Reproductive)
| Term | Definition or Function |
|---|---|
| reproductive system | male and female reproductive systems work together to achieve fertilization and produce offspring |
| (M) testes | located below pelvic cavity on outside of the body (within scrotum) - produces sperm and testosterone |
| (M) scrotum | a pouch of skin that houses the testes |
| (M) penis | external cylinder-shaped organ - moves urine and semen out of the body |
| (M) epididymis | coiled tube located superior to each teste - responsible for maturation of sperm cells |
| (M) vas deferens | connects the epididymis to the urethra |
| (M) seminal vesicles | sac-like organs - secrete seminal fluid that stimulates muscle contractions in the female reproductive organs to aid in propelling sperm forward |
| (M) prostate gland | surrounds the proximal urethra - contracts during ejaculation to aid in forward movement of sperm - secretes fluid that protects sperm within the vagina |
| (M) bulbourethral glands (Cowper's glands) | inferior to the prostate gland - secrete fluid to lubricate the end of the penis to prepare for intercourse |
| (M) androgens | group of male sex hormones |
| (M) testosterone | most abundant and biologically active of male sex hormones |
| (F) ovaries | pair of oval-shaped organs located within the pelvic cavity - ova, estrogen, progesterone |
| (F) fallopian tubes | muscular tubes with proximal open near each ovary - connects distally to uterus - receives egg during ovulation |
| (F) uterus | hollow muscular organ lying lower in pelvic cavity - receives fertilized egg, implants into uterine wall for fetal development - in nonpregnant female, uterine lining sloughs off monthly (menstruation) |
| (F) (uterus) cervix | lower portion of uterus - creates barrier between uterus and vagina - dilates during childbirth |
| (F) vagina | muscular tube extending from uterus to outside of the body - expands during intercourse and childbirth |
| (F) labia majora | folds of skin and adipose tissue that protect other external female genitalia |
| (F) labia minora | folds of skin within the labia majora - pinkish in color due to high blood circulation - forms a hood over the clitoris |
| (F) clitoris | highly sensitive female erectile tissue located anterior to the urethra |
| (F) perineum | area between the vagina and anus |
| (F) estrogen | group of female sex hormones |
| (F) progesterone | hormone secreted by ovaries |
| (F) estradiol | most abundant and biologically active female hormone |
| (F) female reproductive cycle | - refers to monthly fluctuation of hormones that aids in reproduction and prepares the uterus for carrying a child - when fertilization does not occur, menstruation takes place and the process begins again |
