Male Reproductive
Male Reproductive System
| Question | Answer |
|---|---|
| What do you call Human Reproduction? Sexual or Asexual | Sexual |
| What are Sex Cells? | Gametes - Sperm (M) & Ova (F) |
| What are used to form genetically different offspring? | Genes |
| When does the reproductive system become fully functional? | Puberty |
| What are the primary organs of the reproductive system? | Gonads - testes (M) & ovaries (F) Gametes - Sperm (M) & Ova (F) |
| What are the secondary organs of the reproductive system? | Males - ducts, glands, penis, all for storing and transporting sperm Females - location for fusion of egg and sperm, environment for nourishing a fertilized egg, completion of cycle at birth of infant |
| What is the Male reproductive system used for? | Produce, transport, and introduce mature sperm into the female reproductive tract |
| What makes up the male reproductive system? | Scrotum, Testes, Seminiferous tubules, Spermatic Cord, Sperm, Seminal Fluid Ducts, Glands assoc. with seminal ducts, Penis, Hormones |
| What are the 4 Seminal Fluid Ducts? | Epididymis. Ductus (Vas) deferens. Ejaculatory ducts. Urethra. |
| What are the 3 glands associated with the seminal fluid ducts? | Seminal vesicles. Prostate gland. Bulbourethral (Cowper's) gland |
| What is the word used for Scrotum? | Bag |
| What divides interior scrotum into 2 sacs? | Scrotal septum 1 testis, 1 epididymis, and the testicular end of the spermatic cord |
| What does the Scrotal Septum do? | Prevents spread of infection from one testis to the other |
| What is optimum temperature for sperm production? | 2-3 degrees Celsius cooler (34 degrees celsius) than body |
| What is the singular name for gonads? Paired name? | Testis & Testicles |
| What is Tunica Vaginalis? | parietal & visceral layer with cavity |
| What is Tunica Albuginea? | White fibrous capsule around testis |
| How are lobules formed? | by in-folding of Tunica Albuginea - 200-300 lobules in each testis - contains seminiferous tubules & Leydig cells |
| What are Seminiferous Tubules? | -Closed loops that open at top to allow sperm to exit -Drain newly formed sperm through short straight tubules into rete testis |
| What is spermatogenesis? | Site of sperm production |
| What are Leydig Cells? | Produce & Secrete male hormones ie: androgen (testosterone) |
| What hormone is secreted & produced in the male? | androgen (testosterone) |
| Do Leydig cells Increase/Decrease amounts of testosterone in the 7th week? | Increase |
| Where does sperm production occur? | Seminiferous tubules |
| What is Spermatozoa? | sperm |
| What is Spermatgonia? | Baby sperm (stem cells) |
| Where are Spermatogonia found? | on the basement membrane of semininferous tubules |
| What happens to spermatogonia? | undergoes meiosis, reducing chromosome # from 46 to 23 per cell Meiosis also determines that 1/2 the sperm will contain X and the other 1/2 contains Y |
| Where does the Spermatic Cord travel? | suspends testes in scrotum, passes through inguinal canal into pelvic cavity |
| What 4 layers are there of the Spermatic Cord? | 1. Ductus (vas) deferens 2. Autonomic nerves 3. Testicular Artery 4. Testicular Veins |
| What's another name for Testicular vein? | Pampiniform plexus |
| What is a varicocele? | Varicosed testicular vein (also called Bag of Worms) |
| What is a vasectomy? | Small section of ductus (vas) deferens removed from spermatic cord before it enters pelvic cavity. also known as male birth control |
| 300 million produced each day by the testes are what? | Sperm (spermatozoa) |
| What is an Acrosome? | enzymes needed to pass through cervical mucus to help break down outer covering of ovum located in head of sperm |
| What is Rete Testis? | Collecting chambers for sperm, allows sperm to mature partially |
| What is Epididymis? | Tube that connects a testicle to a ductus (vas) deferens and is fertile for 40-60 days in the tail of epididymis |
| What is capacitation? | final maturation completed in the female reproductive tract |
| How does the sperm travel through the reproductive tract? | 1. Rete Testis 2. Epididymis 3. Ductus (vas) Deferens 4. Ejacultory Ducts 5. Urethra |
| What is the Ductus (vas) Deferens? | Tube which "receives" sperm from epdidymis |
| Where does the ductus (vas) deferens go through? | spermatic cord |
| What does the ductus (vas) deferens merge into? | seminal vesicle duct, forming ejaculatory duct |
| When does peristalsis occur in the ductus (vas) deferens? | during sexual arousal |
| What is the Ejaculatory Ducts? | Joins ductus (vas) deferens and seminal vesicle |
| Where does the ejaculatory duct pass through? | prostate gland and opens into prostatic urethra just before ejaculation occurs |
| What is the ejaculatory duct used for? | to eject sperm and seminal vesicle secretions together into prostatic urethra |
| What are the 2 types of urethra's? | Prostatic - passes through prostate gland Spongy (penile) - bulb of penis to external urethral orifice at end of penis ; surrounded by erectile tissue |
| What are the components of the seminal vesicle? | base of bladder ejaculates thick, yellowish fluid - 60% sperm - contains fructose for energy & clotting factor to keep sperm in vagina |
| What are the components of the prostate gland? | encircles urethra and ejaculatory duct |
| What does the prostate gland secrete? | thin, milky fluid - 30% semen - contains citric acid |
| What does the Bulbourethral (cowper's) gland secrete? | mucus for lubricant during sex and neutralizes acid from residual urine in spongy urethra which would injure sperm |
