Chapter 9: Sexual Behavior Flashcards
The internal organs, ovaries in females and testes in males, that produce reproductive cells (eggs and sperm) and secrete sex hormones.
Gonads.
The external sexual organs, including the penis and scrotum in males and the labia, clitoris, and lower third of the vagina in females.
External genitalia.
A condition in which elements of both male and female development occur in the same fetus.
Intersex.
The female gonads; the source of ova and sex hormones.
Ovaries.
The male gonads; source of sperm and sex hormones.
Testes.
A gene located on the short arm of the Y chromosome that encodes for testis-determining factor.
sex-determining region of the Y chromosome (SRY).
The internal system that develops into seminal vesicles, vas deferens, and the prostate gland in males.
Wolffian system.
The internal system that develops into a uterus, fallopian tubes, and the upper two thirds of the vagina in the absence of anti-Mullerian hormone.
Mullerian system.
An androgen produced primarily in the testes.
Testosterone.
A hormone secreted by fetal testes that causes the degeneration of the Mullerian system.
Anti-Mullerian hormone.
A steroid hormone that develops and maintains typically masculine characteristics.
Androgen.
Includes facial hair and a deeper voice for males and wider hips and breast development for females.
Secondary sex characteristics.
A hormone released by the hypothalamus that stimulates the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) by the anterior pituitary gland.
Gonadotropin-releasing hormone (GnRH).
A hormone released by the anterior pituitary gland that stimulates the development of eggs in the ovaries and sperm in the testes.
Follicle-stimulating hormone (FSH).
A hormone released by the anterior pituitary gland that signals the male testes to produce testosterone and that regulates the menstrual cycle in females.
Luteinizing hormone.
Also affects a male’s hairline and can result in baldness later in adulthood.
Testosterone.
In females, produces breast growth, maturity of the external genitalia, maturity of the uterus, and changes in fat distribution and quantity.
Estradiol.
One of several clusters of cells in the ovary each of which contains an egg cell.
Follicle.
A female reproductive cell, or egg.
Ovum.
The process of releasing a mature egg from the ovary.
Ovulation.
A hormone produced in the corpus luteum that prevents the development of additional follicles and promotes the growth of the uterine lining.
Progesterone.
A condition in which some women experience physical and psychological symptoms immediately prior to the onset of menstruation.
Premenstrual syndrome.
