68wm6 reproductive

organized structures of DNA and proteins that are found in cells chromosomes
in women, FSH helps control the menstrual cycle and the production of eggs by the ovaries. In men, FSH helps control the production of sperm follicle-stimulating hormone(FSH)
luteinizing hormone (LH) in the male Interstitial cell stimulating hormone (ICSH)
in the female, an acute rise triggers ovulation. In the male, where LH is called interstitial cell stimulating hormone (ICSH) it stimulates production of testosterone luteinizing hormone
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
Head,acrosome body tail parts of sperm
composed of nucleus, 23 chromosomes, head
contains enzymes to help soerm penetrate an egg cell acrosome
midpiece, consist of a filamentous core, contains many mitochondria body
flagellum, propels sperm cells through semen, mitocondria provides energy for lashing movement tail
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
cylindrical organ, conveys urine and semen, specializes in becoming erect penis
corpora cavernosa a pair of dorsally located cylinders
corpus spongiosum a single cylinder of erectile tissue that surrounds the urethra, forms glans penis
