mother lode for dopamine making cells
VTA (ventral tegmental area)
site where memories are stored during attachment love
anterior cingulate gyrus
cuddle chemical/cuddling hormone
oxytocin
endocrine system uses
hormones and endocrine glands
reproductive hormones
hormones that affect the reproductive organs and bring about the secondary sex characteristics
hormones
chemical signals that have powerful effects on other glands and tissues because they stimulate their metabolism in a particular way
steroid hormones
soluble in plasma membrane, so they can cross the membranes and enter a cell
peptide hormones
not soluble in the plasma membrane, so they can't pass through
pheromones
chemical signals that act at a distance between individuals, particularly members of the opposite sex
hypothalamus
a region of the brain that has many effects on the body
posterior pituitary
stores antidiuretic hormone (ADH) and oxytocin
positive feedback mechanism
controls the release of oxytocin from the posterior pituitary
anterior pituitary
secretes hormones, including growth hormone (GH) and prolactin (PRL)
growth hormone (GH)
promotes cell division, protein synthesis, and bone growth
prolactin (PRL)
causes mammary glands in the breasts to develop and produce milk
thyroid gland
releases hormones that don't have a specific target organ, but stimulate most of the cells in the body to metabolize at a faster rate
andrenal cortex
secretes a small amount of male sex hormone and female sex hormone in both sexes
gonadotropin-releasing hormone (GnRH)
stimulates the anterior pituitary to secrete gonadotropic hormones, which are follicle-stimulating hormone (FSH) and luteinizing hormone (LH)
gonadotropic hormones
stimulate gonads to produce gametes and sex hormones
gonads
testes in males and ovaries in females
androgens
male sex hormones (i.e. testosterone); produced in testes
estrogen and progesterone
female sex hormones; produced in ovaries
negative feedback system
maintains the level of sex hormones
SRY gene
one of the genes on the Y chromosome; the sex-determining region of the Y; presence or absence of this gene makes one male or female
pineal gland
located in brain; secretes melatonin
circadian rhythms
rhythms with a period of 24 hours
secondary sex characteristics
those differences between the sexes that usually allow us to tell males from females
anabolic steroids
synthetic forms of testosterone
male primary sex organs
testes
epididymis
stores sperm produced by testes
spermatogenesis
the production of sperm
androgens
cells that secrete male hormones
germ cells
involved in spermatogenesis
sustentacular (sertoli) cells
support, nourish, and regulate development of cells undergoing spermatogenesis
acrosome
found in sperm; stores enzymes that penetrate the egg
vasa deferentia
conduct and store sperm
seminal vesicles
contribute nutrients and fluid to semen
prostate gland
contributes basic fluid to semen
urethra
conducts sperm
bulbourethral glands
contribute mucosal fluid to sperm
penis
the male organ of sexual intercourse by which sperm are introduced into the female reproductive tract
circumcision
a surgical procedure in which the foreskin/prepuce of the penis is removed
uterine/fallopian tubes
conduct egg; location of fertilization
uterus/womb
houses developing fetus
cervix
contains opening to uterus
vagina
receives penis during sexual intercourse, serves as birth canal and as an exit for menstrual flow
endometrium
lining of the uterus; participates in formation of placenta
vulva
the external genital organs of the female, collectively
follicles
each contains an immature egg, called an oocyte
oogenesis
the production of an egg
ovulation
when the vesicular follicle bursts, releasing the secondary oocyte surrounded by a clear membrane and attached follicle cells
hymen
ring of tissue enclosing vaginal orifice
labia majora
2 large, hair-covered folds of skin that extend posteriorly from the mons pubis (a fatty prominence underlying pubic hair)
labia minora
2 small folds of skin lying just inside the labia majora
clitoris
an organ that is homologous to the penis
vestibule
cleft between the labia minora
