|
bulbourethral gland
|
in male mammals, a gland that secretes a basic, mucus containing fluid that forms part of the semen
|
|
|
cervix
|
a ring of connective tissue at the outer end of the uterus, leading into the vagina
|
|
|
endocrine cells
|
cells that release their secretions into the extracellular fluid from which the secretions diffuse into nearby capillaries
|
|
|
endometrium
|
the nutritive inner lining of the uterus
|
|
|
epididymis
|
a series off tubes that connect with and receive sperm from the seminiferous tubules of the testis
|
|
|
estrogen
|
a female sex hormone, produced by follicle cells of the ovary, that stimulates follicle development, oogenesis, the development of secondary sex characteristics and growth of the uterine lining
|
|
|
fimbriae
|
the ciliated, fingerlike projections of the oviduct that sweep the ovulated egg from the ovary into the oviduct
|
|
|
follicle stimulating hormone
|
a hormone, produced by the anterior pituitary, that stimulates spermatogenesis in males and the development of the follicle in females
|
|
|
gametes
|
a haploid sex cell formed in sexually reproducing organisms
|
|
|
gonadotropin releasing hormone
|
a hormone produced by the neurosecretory cells of the hypothalamus, which stimulates cells in the anterior pituitary to release FSH and LH. it is involved in the menstrual cycle and in spermatogenesis
|
|
|
gonads
|
an organ where reproductive cells are formed; in males, the testes, and in females, the ovaries
|
|
|
hormone
|
a chemical that is synthesized by one group of cells, secreted, and then carried in the bloodstream to other cells, whose activity is influenced by reception of the hormone
|
|
|
ovary
|
the gonad of females
|
|
|
penis
|
an external structure of the male reproductive system, serves to deposit sperm into the female reproductive system and delivers urine to the exterior
|
|
|
pituitary gland
|
an endocrine gland, located at the base of the brain, that produces several hormones many of which influence the activity of other glands
|
|
|
prostate gland
|
a gland that produces part of the fluid component of semen; prostatic fluid is basic and contains a chemical that activates sperm movement
|
|
|
scrotum
|
the pouch of skin containing the testes of male mammals
|
|
|
seminal vesicles
|
a gland that produces a basic, fructose-containing fluid that forms part of the semen
|
|
|
seminiferous tubules
|
a series of tubes in which sperm are produced, in the testes
|
|
|
sexual reproduction
|
a form of reproduction in which genetic material from two parent organisms is combined in the offspring; normally, two haploid gametes fuse to form a diploid zygote
|
|
|
target cell
|
a cell on which a particular hormone exerts its effect
|
|
|
testes
|
the male gonad
|
|
|
testosterone
|
a hormone produced by the interstitial cells of the testis; stimulates spermatogenesis and the development of male secondary sex characterstics
|
|
|
urethra
|
receives sperm from the vas deferens and conducts sperm to the tip of the penis
|
|
|
uterine tube
|
also called the oviduct, the tube leading from the ovary to the uterus into which the secondary oocyte (egg cell) is released
|
|
|
uterus
|
the part of the reproductive tract that houses the embryo during pregnancy
|
|
|
vagina
|
the passageway leading from the outside of a female mammal's body to the cervix of the uterus
|
|
|
vas deferens
|
the tube connecting the epididymis of the testis with the urethra
|
