Can you identify the parts?

Can you identify the parts?Here is a very simplified drawing.

There are 6 of the parts marked that you might be able to identify.

This is more detailed anatomically precise drawing.

There are two cross-sectional views:-from side-from above

In this drawing you can see ALL of the 9 parts plus some additional body parts.

What is this?

It is greatly magnified.

Structure Function Description Other details

Penis1) Sexual pleasure2) Reproduction

-skin loose & hairless-spongy tissue along side & bottom-head is smooth-length: 8 cm non-erect13 cm erect

-a foreskin overhangs glans(removed if circumsized)-glan has many nerve endings & is sensitive, especially underside-erection occurs when spongy tissue fills with blood

Penis 1) Excretion2) Sexual pleasure3) Reproduction

The uncircumcised penis AND the circumcised penis

scrotum -supports, encloses, & protects the testes-

-maintains temperature by: -contracting muscles changing surface area -sweating -changing supply of blood

scrotum -supports, encloses, & protects the testes-

scrotum -supports, encloses, & protects the testes-regulates temperature of testicles

-sac---

-sac-skin thin--

-sac-skin thin-darkly pigmented-

-sac-skin thin-darkly pigmented-covered with light hair

Testicles (testes) -produces the hormone testosterone-

-two oval glands-4 cm long, 2.5 cm thick-

-enclosed in scrotum-left usually hangs lower than right-takes 60-72 days to produce one sperm-millions produced every day-develop in abdomen & usually descend 2 months before birth

Testicles (testes) -produces the hormone testosterone-

Testicles (testes) -produces the hormone testosterone-produces sperm

-two oval glands-4 cm long, 2.5 cm thick-has 100s of coiled canals (1.6 km in length)

Epidydymis -sperm are produced here-provides path for sperm out of the testicles

-coiled canals inside the testes-

epidydymis -sperm are produced here-provides path for sperm out of the testicles

-coiled canals inside the testes-shape of comma

Vas Deferens -pathway for sperm to travel out of testes

-thin-walled, powerful muscles--widen out at the bottom

-at the end are storage containers callled ampulla

-thin-walled, powerful muscles-35 cm long-widen out at the bottom

-at the end are storage containers called ampulla

Urethra -pathway for sperm and urine-conducts urine from bladder to outside body-carries semen from ejaculatory duct to outside of body

urethra -pathway for sperm and urine-conducts urine from bladder to outside body-carries semen from ejaculatory duct to outside of body

-tube from bladder through penis

-opening of urethra is at tip of penis

Seminal vesicles

Prostate

Cowper Glands or Bulbourethral

-produces fluid for sperm nutrition and transportation

-produce fluid which lubricates urethra & neutralizes acide there

-2 on either side of vas deferens
