Male Reproductive System Flashcards
Reproductive structures in either sex, male or female, typically include the following basic structures:
Gonads, accessory glands and organs, external genetalia
What are gonads?
organs that produce gametes (sperm/egg) and hormones
- testes
- ovaries
Structures of the perineum that collectively are known as
external genitalia
Each _____ produces sperm and hormones
testis
Each ______ is the site of sperm maturation
epididymis
Each ____________ (sperm duct) conduct sperm between the testis and prostate gland
ductus (vas) deferens
Each _________ secretes fluid that makes up most of the volume of semen
seminal vesicle
The _______ secretes fluid and enzymes
prostate gland
The ___________ secrete mucus
bulbourethral glands
The ______ conducts semen to the exterior
urethra
The ____ contains erectile tissue, produces pleasurable sensations during sexual activity, and transports sperm.
penis
The _____ surrounds the testes
scrotum
The testis is divided into lobules that contain the coiled _______ ______, where sperm production occurs
seminiferous tubules
The ________ is a coiled tube through which sperm pass while completing functional maturation. It has a head, body, and tail
epididymis
The production of sperm and the endocrine secretion of _________ from the testis is controlled by follicle stimulating hormone (FSH) and luteinizing hormone (LH) produced by the anterior lobe of the pituitary gland
testosterone
The production of sperm and the endocrine secretion of testosterone from the testis is controlled by _________ and _____________ produced by the anterior lobe of the pituitary gland
follicle stimulating hormone (FSH) luteinizing hormone (LH)
________ stimulates bone and muscle growth, establishes and maintains secondary sex characteristics, maintains the glands and organs of the male reproductive tract and has effects on libido (sexual drive)
Testosterone
Each ________ ascends to enter the abdominal cavity through the superficial inguinal ring. The ductus deferens transports sperm from the epididymis
ductus deferens
The _____ includes the ductus deferens and blood vessels, nerves and lymphatic vessels that supply the testis
spermatic cord
The ductus deferens enters the abdominal cavity and passes posterior to the urinary bladder to reach the ________
Prostate gland
The ________ passes behind the urinary bladder to reach the prostate gland
ductus deferens
The ________ also are located posterior to the urinary bladder. They produce roughly 60% of the volume of seminal fluid
seminal vesicles
The _________ encircles the proximal portion of the urethra as it leaves the urinary bladder. It produces roughly 30% of the volume of seminal fluid.
Prostate gland
The __________ also empty into the urethra. They secrete a thick mucus that helps neutralize acids that remain in the urethra and it also lubricates the tip of the penis
bulbourethral glands
_______ includes sperm and the secretions of the structures of the rest of the male reproductive tract
semen
The _____ consists of a layer of skin and underlying superficial fascia.
scrotum
The left and right _______ cavities are separated by a septum of fascia.
scrotal
The _____ functions to conduct urine and semen to the exterior.
penis
The _____ surrounds the external urethral orifice
glans
The _____ or foreskin is a fold that surrounds the tip of the penis
prepuce
What makes up the axial musculature of the urogenital triangle
- ischiocavernosus
- bulbospongiosus
- superficial transverse perineal
The penis consists of ______ cylindrical columns of well-vascularized erectile tissue.
three
The paired _____________are located on the dorsal side of the penis and the ______________ surrounds the urethra.
corpora cavernosa
corpus spongiosum
The penis expands at the end to form the ______
glands
The 3 phases associated with male sexual response
- Arousal
- Emission
- Ejaculation
Arousal is caused by which part of the nervous system
parasympathetic (point)
Emission and ejaculation are caused by which parts of the nervous system
sympathetic and somatic (shoot)
