Ch 34 Male Reproductive System Flashcards
Sperm flows in the following order: (7 items)
Testes (scrotum)
Epididymis
Ductus Deferens (vas deferens)
Ejaculatory Duct
Prostate gland
Urethra
Penis
There are 2 testes that contains many _ _ that produce the male sex cell (sperm/ spermatozoa) and the male hormone, testosterone
seminiferous tubules
The testes are found _ to the abdominal cavity within a skin pouch called the _.
external
scrotum
Testes are found in the scrotum outside of the abdominal cavity because sperm production requires a slightly _ temperature than body temperature to occur
lower
The epididymis is a _ shaped structure found on the _ surface of each testis
C shaped
posterior
The _ receives sperm from the testes and stores it until it is released via ejaculation
epididymis
The path of the ductus (vas) deferens:
1) Begins at each _
2) courses within a _ _
3) courses thru an inguinal _
4) courses along the surface of the _
5) courses inferiorly along its surface where it terminates, joining the seminal vesicle forming the _ _ .
epididymis
spermatic cord
inguinal canal
bladder
ejaculatory duct
The spermatic cord is a structure that is formed collectively by the _ _ and its veins and arteries and ascends thru the scrotum to the _ _.
ductus deferens/ vas deferens
inguinal ring
The inguinal canal is an opening in the _ _ muscle thru which the spermatic cord passes
external oblique muscle
The ductus deferens of each side terminates by joining the duct of the _ _ and thereby forming the ejaculatory duct
seminal vesicle
Seminal vesicles are _ glands found on the _ surface of the bladder
exocrine
posterior
Seminal Vesicles are one of 3 types of glands that produce seminal fluid which are referred to as _ _ of the male reproductive system
accessory glands
Seminal vesicles are exocrine glands and are drained by the _ of the seminal vesicle
duct
The ejaculatory duct is formed by the joining of the _ _ and the duct of the _ _. The ejaculatory duct is found on each side _ to the bladder and _ the prostate.
ductus deferens
duct of the seminal vesicle
posterior
above
The ejaculatory ducts enter the _ of the prostate gland
substance
The prostate gland is the second _ _ of the male reproductive system and secretes seminal fluid that joins that which was produced by the _ _
accessory gland
seminal vesicles
The prostate gland is found in the pelvis _ to the pubis and _ the bladder
posterior
below
Within the prostate gland the 2 ejaculator ducts join with the duct draining the _ to form the _
bladder
urethra
The male urethra is a _ tube that extends from the prostate gland thru the _ _ and then thru the penis to outside the body
fibromuscular
urogenital diaphragm
The male urethra is subdivided into 3 parts:
prostatic
membranous
spongy
The prostatic urethra traverses the _ gland
prostate
The membranous urethra traverses the _ _
urogenital diaphragm
The spongy urethra traverses the _.
penis
2 small exocrine glands called _ _ are found on either side of the urethra within the substance of the urogenital diaphragm at the level of the _ urethra.
bulbourethral glands
membranous
The bulbourethral gland is the _ accessory gland of the male reproductive system and drains additional _ _ via ducts directly into the _ urethra
3rd
seminal fluid
spongy urethra
The 3 longitudinal connective tissue structures of the penis that fill with blood when erect are called _ _ .
venous sinuses
2 of the 3 venous sinuses on a penis are called _ _ and only contain the venous sinuses themselves.
corpORA cavernosum
1 of the 3 venous sinuses on a penis is called the _ _ which also contains the spongy urethra in addition to the sinuses
corpUS spongiosum
Arterial supply to the male reproductive system mainly comes from the _ _ artery and other branches of the _ _ artery.
Internal Pudendal Artery
Internal Iliac Artery
The gonadal artery, called the _ artery in men, mainly supplies the _ and _.
testicular
testes
epididymis
