What do the Bladder, Seminal Vesicle, Vas Defirnes, Prostate Gland, Cowpeis Gland, Epididqmis, Testicles,Scortum, Urethra mean? I'm having trouble with the definitions.
These are all parts of male anatomy. You can look these up on a hard copy or online dictionary, if you spell them correctly. Below are my class notes covering these concepts.
II. Scrotum is a bag of skin below that is covered with hair at maturity. It functions like a radiator to keep sperm about 5 degrees F below body temperature for sperm viability. Scrotum contains:
A. Testes (testicles), which are aligned one slightly below the other. They contain:
1. Seminiferous tubules are responsible for spermatogenesis of about 500 million sperm a day. Sperm production of about 500 million/day related to FSH from pituitary. Sperm have a head, neck and tail and take 65-75 days to develop.
2. Leydig (interstitial) cells are between tubules and produce androgens like testosterone. Hormone production related to interstitial cell stimulating hormone (ICSH, analogous to LH in women) from the pituitary.
B. Epididymus is 20-foot long tubule on top of and in back of each teste where sperm mature.
C. From the epididymus, the sperm travel (.5"/5 minutes) up the vas deferens to reach the urethra via the ejaculatory ducts.
D. Men should give themselves testicular exam monthly.
III. Perineum is sensual area between genitals and anus of both genders.
IV. Semen is the male ejaculate, which varies from milky white to yellowish or grayish in color. It combines:
A. With 150-500 million per ejaculation, sperm is about 1% of semen volume.
B. Fluid from seminal vesicles are almost two-thirds of volume. This fluid contains sugars to nourish sperm and give them energy to move. Sperm are dormant before ejaculation, but the alkaline property of this fluid (and others) activates the sperm. This fluid is white to yellowish with a mucus-like consistency.
C. The prostate is a gland at the base of the bladder with both the urethra and ejaculatory ducts going through it. It blocks off the bladder during ejaculation and blocks ejaculatory duct during urination. Its fluids are alkaline and whitish in color and close to one-third of the volume of semen. Prostatic problems are likely to occur in men over 50 years old. A prostatectomy will lead to a retrograde ejaculation and sterility.
D. Cowper's (bulbourethral) glands release a small amount of clear, mucus-like fluid during sexual excitement (without sensation) before ejaculation. This fluid neutralizes urine in the urethra and lubricates the glans. In contrast to semen with its cloudy white color, Cowper's fluid is clear and has very few (35,000-50,000) sperm, if any.
If any of the above terms are still confusing or are not included, you can look them up.
I hope this helps. Thanks for asking.
The terms you mentioned are all related to male reproductive anatomy. Here is an explanation of each term:
1. Bladder: The bladder is a hollow organ located in the lower abdomen. Its function is to store urine produced by the kidneys before it is eliminated from the body through the urethra.
2. Seminal Vesicle: The seminal vesicles are a pair of small glands located behind the bladder. They produce and secrete a fluid that makes up a significant portion of semen. This fluid provides nourishment and energy to the sperm.
3. Vas Deferens: The vas deferens is a muscular tube that carries sperm from the epididymis to the urethra during ejaculation. It is an important part of the male reproductive system.
4. Prostate Gland: The prostate gland is a small gland that surrounds the urethra, which is the tube that carries urine and semen out of the body. It produces a fluid that mixes with sperm and seminal vesicle fluid to create semen.
5. Cowper's Gland: Also known as the bulbourethral gland, Cowper's gland is a pair of small glands located beneath the prostate gland. They produce a clear, mucus-like fluid that helps lubricate the urethra during sexual arousal.
6. Epididymis: The epididymis is a long, coiled tube located on top of each testicle. It serves as a site for the maturation and storage of sperm before they are ejaculated.
7. Testicles: Testicles, also known as testes, are a pair of oval-shaped organs located within the scrotum. They are responsible for producing sperm and testosterone, the male sex hormone.
8. Scrotum: The scrotum is a pouch of skin that holds and protects the testes. Its muscular walls help regulate the temperature of the testes, which is essential for proper sperm production.
9. Urethra: The urethra is a tube that carries urine from the bladder and semen from the ejaculatory ducts to the outside of the body. It runs through the and serves as a common pathway for both urine and semen.
I hope this explanation helps clarify the definitions of these terms for you. If you have any further questions, feel free to ask.
