Male Reproductive System: word parts

Exam #3: anatomy, word parts

Origination and transportation of sperm

formed in seminiferous tubules (testes) —> epididymis —> vas deference —> seminal vesicle and duct —> urethra —> prostate gland —> penis —> outside body

testis (pl. testes)

primary sex organ, paired, oval-shaped, and enclosed in a sac called the scrotum; produces spermatozoa (sperm cells) and testosterone

aka testicle

seminiferous tubules

approximately 900 coiled tubes w/n the testes in which spermatogenesis occurs

sperm

the microscopic male germ cell, which, when united w. the ovum, produces a zygote (fertilized off) that w. subsequent development becomes an embryo

aka spermatozoon, pl. spermatazoa

testosterone

the main male sex hormone

Fx: stimulate the development of the male reproductive organs and 2ndary sex characteristics (ex: facial hair)

epididymis

coiled tube attached to each testis that provides for storage, transit, and maturation of sperm; continuous with each vas deferens

vas deferens

duct (tube) carrying the sperm from the epididymis to the urethra

the spermatic cord enclosed each ___ w. nerves, lymphatics, arteries, and veins. Since the urethra also connects with the urinary bladder to carry urine out the body, a circular muscle constricts during intercourse to prevent urination

aka ductus deferens

seminal vesicles

2 accessory glands located posterior to the base of the bladder that open into the vas deferens. The glands secrete a thick fluid that forms part of the semen

prostate gland

walnut-shaped gland that encircles the proximal section of the urethra. It secretes a fluid that aids in the movement of the sperm and ejaculation

(located anterior/before) the bladder

semen

composed of sperm, seminal fluids, and other secretions

scrotum

sac containing the testes and their corresponding epididymides, from which each vas deferens begins. It is suspended on both sides of and posterior to the penis.

penis

male organ of urination and coitus (sex)

glans penis

enlarged tip on the end of the penis

prepuce

fold of skin covering the glans penis in uncircumcised males (foreskin of the penis)

genitalia (aka genitals)

reproductive organs (M/F); includes internal and external reproductive organs

gonads

primary reproductive organs; testes = M; ovaries = F

andr/o

male

balan/o

glans penis

epididymis/o

epididymis

orch/o

testis, testicle (o)

orchi/o

testis, testicle (i)

orchid/o

testis, testicle (d)

prostat/o

prostate gland

sperm/o

sperm, spermatozoon (pl. spermatozoa)

spermat/o

sperm, spermatozoon (pl. spermatozoa) (t)

vas/o

vessel, duct (vas deferens in terms of describing the M repro system)

vesicul/o

seminal vesicle(s)

cyst/o

bladder, sac

crypt/o

hidden

lith/o

stones, calculus

olig/o

scanty, few

-plasia

-plasty

surgical repair

-rrhea

flow, discharge

-stomy

creation of an artificial opening

andropathy

disease of the male (specific to the male)

anorchism

state of absence of testis (uni or bilateral)

balanitis

inflammation of the glans penis

balanorrhea

discharge from the glans penis

benign prostatic hyperplasia (BPH)

excessive development pertaining to the prostate gland

(nonmalignant enlargement; causes narrowing of urethra = interferes w. passage of urine) Sx: frequency of urination, nocturne, utinary retention, incomplete emptying of bladder

aka benign prostatic hypertrophy

prostatic hyperplasia

tissue changes resulting from an abnormal incr. in the # of cells as may occur w. age

cryptorchidism

state of hidden testis; aka undescended testicle(s)

(during fetal development testes are located in abdominal area near kidneys. Before birth they move down into scrotal sac; failure to descend from abd cavity results in this)

epididymitis

inflammation of the epididymis

orchiepididymitis

inflammation of the testis and the epididymis

orchitis (aka orchiditis)

inflammation of the testis

prostatitis

inflammation of the prostate gland

prostatocystitis

inflammation of the prostate gland and the (urinary) bladder

prostatolith

stone(s) in the prostate gland

prostatorrhea

discharge from the prostate gland

prostatovesiculitis

inflammation of the prostate gland and the seminal vesicles
