Chapter 26: Reproductive systems

mixture of sperm and the secretion of the accessory glands

semen

tubular structure that carries both urine and semen

urethra

two ejaculatory ducts pass through the prostate gland and join with this urinary structure

urethra

Composed of the menstrual, proliferative, and secretory phases, bleeding characterizes the menstrual phase of this cycle, the secretory phase of this cycle is primarily caused by the secretion of progesterone, and the proliferative phase of this cycle is primarily caused by the secretion of estrogen

uterine cycle

caused by the filling of the erectile tissue by blood

erection

female gonads that target glands of FSH and LH

ovaries

Ejection of a mature egg at midcycle

ovulation

female gamete

ovum

male copulatory organ

penis

piece of skin that is circumcised; also called the foreskin

prepuce

skin, skin, skin, skin,

prepuce

Secreted by the hypothalamus

releasing hormones

The corpus luteum dies and becomes to this nonsecreting structure, also known as the white body

corpus albicans

ovarian structure that primarily secretes progesterone

corpusluteum

The vas deferens curves and joins with the duct of the seminal vesicle to form this duct

ejaculatory duct

movement of sperm and glandular secretions from the tests and the genital ducts into the urethra

emission

coiled structure that sits on top of the testes; a place where sperm mature

epididymis

Adenohypophyseal gonadotropin that acts on the ovary to stimulate the development of a follicle

follicle-stimulating hormone

cells taht surround the oocytes

follicular cells

The ovaries primarily secrete estrogen during this phase of the ovarian cycle

follicular phase

Classification of FSH and LH

gonadotropins

mature ovarian follicle

graafian follicle

Thin membrane that partially covers the vaginal opening

hymen

Cells that secrete testosterone

interstitial cells

The ovaries primarily secrete progesterone during this phase of the ovarian cycle

luteal phase

Also called interstitial cell-stimulating hormone (ICSH); stimulates the interstitial cells to secrete testosterone

lutenizing hormone

immature egg

oocyte

Female gonads

ovaries

doughnut-like gland that surrounds the upper part of the urethra as it leaves the bladder; this gland contributes to the formation of semen

prostate

gland that encircles the upper part of the urethra; when enlarged, it impairs urination (dysuria)

prostate

the hypothalamus secretes these hormones, which in turn stimulate the anterior pituitary gland to release gonadotropins

releasing hormones

Also called the period

menstrual phase

Mature male gamete

sperm

A surge of this hormone immediately precedes ovulation

LH

Gladn that secretes 60% of the semen

seminal vesicles

an androgen necessary for sperm development and for the male secondary sedx characteristics

testosterone

Male gonads; also called testicles

Testes

4-inch muscular tube that extends from the cervix to the vaginal opening on the perineum

vaging

Ordering 3:

Ordering: Vas deferens

Ordering 4:

Ordering: ejaculatory duct

structure that produces sperm and secretes testosterone

testes

implantation of the embryo occurs here, also called the womb, the growing embryo and fetus live here for 9 months, pear-shaped organ that is held in place by the broad ligament, layers of this organ are the epimetrium (perimetrium), myometrium, and endometrium, organ that has borne the entire human race

uterus

undifferentiated spermatogenic cells

spermatogonia

When blood levels of estrogen adn progesterone decrease at the end of the secretory phase of the uterine cycle, and anterior pituitary secretes this gonadotropin in an attempt to stimulate the development of another egg

FSH (follicle-stimulating hormone)

Ordering 2:

Ordering: epididymis

Ordering 1:

Ordering: seminiferous tubules

Ordering 5:

Ordering: urethra

The "pill" contains estrogen and this hormone, Hormone that is primarily secreted by the ovaries during hte luteal phase of the ovarian cycle, Ovarian hormone that dominates the secretory phase of the uterine cycle

Progesterone

the penis enlarges and becomes rigid

erection

Promotes the maturation of the egg and the development of the female secondary sex characteristics, hormones that is primarily secreted by the ovaries during the follicular phase of the ovarian cycle, A female looks female primarily because of this hormone, ovarian hormone that dominates the proliferative phase of the uterine cycle

estrogen

Mons pubis, labia, and clitoris; also called the vulva

external genitals

name for the penis and the scrotum

external genitals

Contains the infundibulum and fimbriae; transports the ovum to the uterus, fertilization occurs here

fallopian tube

called oviducts or uterine tubes

fallopian tubes

Hormones that stimulates the corpus luteum during early pregnancy and prevents its deterioration

human chorionic

The inability to achieve an erection; also called erectile dysfunction

impotence

pleasurable sensation experienced during ejaculation

orgasm

Composed of the follicular phase and luteal phase

ovarian cycle

skin-covered muscular region between the vaginal orifice and the anus

perineum

Sac or pouch located between the thighs; holds the testicles

scrotom

composed of a head, body (midpiece), and tail

sperm
