🗑
|
||||
| luteinizing hormone (LH) in the male | Interstitial cell stimulating hormone (ICSH)
🗑
|

||||
| a type of cell division by which germ cells (eggs and sperm) are produced. Meiosis involves a reduction in the amount of genetic material | meiosis
🗑
|
||||
| process by chich a cell duplicates the chromosomes in its cell nucleus, in order to generate two, identical, daughter nuclei | mitosis
🗑
|
||||
| the creation of an ovum (egg cell) | oogenesis
🗑
|
||||
| occurs when a mature egg is released from the ovary | ovulation
🗑
|
||||
| the process by which male spermatogonia develop into mature spermatozoa | spermatogenesis
🗑
|
||||
| a cell that is the result of fertilization | zygote
🗑
|
||||
| male primary sex organ | testes
🗑
|
||||
| produce and secrete primary male sex hormone, testosterone | interstitial cells
🗑
|
||||
| seminiferous tubules | sperm is formed here
🗑
|
||||

🗑
|

||||
| male internal reproductive organs | epididymis, vas deferens, seminal vesicles, prostate gland, bulbourethral gland, semen
🗑
|
||||
| tightly coiled tube. about 20 feet in length, emerges from top of testis, leads into the vas deferens, stores sperm until they mature | epididymis
🗑
|
||||
| muscular tube, ends behind urinary bladder, joins seminal vesicle to form the efaculatory duct | vas deferens
🗑
|
||||
| pouchlike structure attached to the vas deferens, secretes rich in fructose and other nutrients, accounts for 60% of semen volume | seminal vesicle
🗑
|
||||
| doughnut shaped, surounds urethra below the bladder, it secretes a thin, milky, alkaline fluid which neutralizes semen, accounts for 30% of semen volume, enhances sperm motility | prostate gland
🗑
|
||||
| located below the prostate gland, responds to sexual stimulation, secretes mucus-like fluid, often called pre-ejaculate, protects sperm from damage, accounts for less than 5% of semen volume, also called cowpers gland | bulbourethral gland
🗑
|
||||
| slightly alkaline, contains nutrients and prostaglandens, enhance sperm cell survival and movement through female reproductive tract | semen
🗑
