Identify the different structures, and interpret the functions of the male reproductive system.
scrotum, testis, epidiymis, vas deferens, urethra, penis, seminal vesicles, prostate gland, bulbourethral glands; production and storage of sperm and delivering sperm to the female
Describe the relationship between internal feedback mechanisms and the regulation of male reproductive hormones.
The hypothalamus produces releasing hormones, which cause FSH and LH to be secreted from the pituitary. FSH regulates sperm production and LH regulates testosterone production in the testes. As testosterone levels increase, the production of FSH and LH is inhibited by negative feedback.
Identify the different structures, and interpret the functions of the female reproductive system.
ovary, oviduct, uterus, vagina; produce eggs, receive sperm, and provide an environment in which a fertilized egg can develop
Sequence and describe the stages of the menstrual cycle.
1)flow phase: 1–5 days, shedding of the uterine lining;
2)follicular phase: 6–14 days, follicle develops, endometrial and uterine linings increase, ovulation occurs;
3)luteal phase: 15–28 days, old follicle becomes corpus luteum
What might happen to sperm production if a male has a high fever?
Sperm may be killed by the high fever. They need a cool environment to develop.
Using the terms posterior, superior, and inferior, describe where the epididymis is located in relation to the vas deferens. Where is the prostate located in relation to the testes and bladder, respectively?
Epididymis is inferior to the vas deferens; Prostate superior to the testes and inferior to the bladder
in males, the sac suspended directly behind the base of the penis that contains the testes.
in human males, the coiled tube within the scrotum in which the sperm complete maturation.
in males, duct that transports sperm from the epididymis towards the ejaculatory ducts of the urethra.
vas deferens
in males, pair of glands located at the base of the urinary bladder that secrete a mucouslike fluid into the vas deferens.
seminal vesicle
in human males, single gland that lies below the bladder and surrounds the top portion of the urethra; secretes a thin, alkaline fluid that helps sperm move and survive.
prostate gland
glands located beneath the prostate that secrete a clear, sticky, alkaline fluid that protects sperm by neutralizing the acidic environment of the vagina.
bulbourethral glands
combination of sperm and fluids from the seminal vesicles, prostate gland, and bulbourethral glands.
in humans, the period when secondary sex characteristics begin to appear; changes are controlled by sex hormones secreted by the endocrine system.
in females, the tube that transports eggs from the ovary to the uterus.
lower end of the uterus that tapers to a narrow opening into the vagina.
in human females, group of epithelial cells that surround a developing egg cell.
in females, the process of an egg rupturing through the ovary wall and moving into the oviduct.
in human females, the monthly cycle that includes the production of an egg, the preparation of the uterus to receive an egg, and the shedding of an egg if it remains unfertilized.
menstrual cycle
part of an ovarian follicle that remains in the ovary after ovulation; produces estrogen and progesterone.
corpus luteum
