Reproductive Anatomy Flashcards
Primary sex organs are called
gonads
Primary sex organs of female are
ovaries
Primary sex organs of male are
testes
Female produces ______ oocytes monthly
1
Male produces _____ of sperm daily
100,000,000s
Sperm are stored and mature in
epididymis
If sperm aren’t expelled from the body within a certain period, they are ____
resorbed
_____ produce large amounts of sex hormones which affect maturation, development, and changes in the activity of the reproductive system organs.
Gonads
Sex hormones in females
estrogen and progesterone
Sex hormones in males
androgens (testosterone and dihydrotestosterone)
Both males and females have accessory reproductive organs including ______ to carry gametes away from the gonads toward the site of fertilization
duct systems
Epididymis, Ductus (vas) deferens, Ejaculatory duct, and Urethra make up the ______
efferent duct
The seminal vesicles, prostate, and bulbourethral glands make up the
3 accessory glands
_______ are the primary gonads that produce and synthesize sperm and hormones
testes
is a fibromuscular cutaneous sac, located between the penis and anus.
scrotum
the site of sperm & testosterone production.
Testis
functions as a storage reservoir for sperm & site of sperm maturation.
Epididymis
a collection of muscle fibers, vessels, nerves and ducts that run to and from the testes.
Spermatic cord
What are the 3 paired structures of the scrotum?
testis, epididymis, and the spermatic cord
What are the muscle fibers within scrotum?
dartos and cremaster
_____ muscle is a sheet of smooth muscle, situated immediately underneath the skin. It acts to help regulate the temperature of the scrotum, by wrinkling the skin –this decreases surface area, reducing heat loss
dartos muscle
Originally, the testes are located on the ________
posterior abdominal wall
T/F: As the testes descend through the inguinal canal to the scrotum, they carry their neurovascular supply with them
True
During embryonic development they descend down the abdomen, and through the _______ to reach the scrotum.
inguinal canal
Arterial supply to the testes and epididymis is via the paired _____ arteries
testicular arteries
Lymphatic drainage to the testes is to the ________ nodes
lumbar lymph and preaortic nodes
Network of nerves derived from the renal and aortic plexi that innervate the testis
testicular plexus
The ______ is a network of veins, responsible for the venous drainage of the testes, acts as a heat exchanger, cooling the arterial blood before it reaches the testes.
pampiniform plexus
As it travels through the inguinal canal, the pampiniform plexus condenses into a
single testicular vein
The right testicular vein drains into the
inferior vena cava
the left testicular vein drains into the
left renal vein
_____ is a comma-shaped structure composed of an internal duct and an external covering of connective tissue. •Internally contains a long, convoluted duct, which is approximately 4 to 5 meters in length
epididymis
T/F: Sperm must reside in the epididymis for a period of time to become mature and fully motile (capacitation).
True
If sperm are not ejected from the male reproductive system in a timely manner, the old sperm degenerate in the
epididymis
