Chapter 9 Flashcards
stimulate Wolffian system
anti-Mullerian hormone
what occurs during defeminization in the male
Anti-Mullerian hormone released Mullerian system withers away
what hormone is released during the masculinization stage in males
androgens
gonadotropin releasing hormone
found in hypothalmus, stimulates anterior pituitary gland to secrete gonadotropic hormone
gonadotropic hormone
hormone found in anterior pituitary gland that has a stimulating effect on the cells of the gonads
causes XY females due to a malfunctioning androgen inteceptor
androgen sensitivity
androgenital syndrome
- deficit in the adrenal cortisol release
- body tries to make up for deficit (adrenal hyperactivity)
- leads to an excess of androgens
Congenital adrenal hyperplasia
adrenogenital syndrome
hypersecretion of androgens by the adrenal cortex
- causes masculinization in females
Persistent Mullerian duct syndrome
condition caused by lack of anti-Mullerian hormone or receptors for this hormone
- cause development of both male and female internal sex organs in males
androgen insensitivity syndrome
caused by a congenital lack of functioning androgen receptors
- in a person w/ XY sex chromosomes this causes development of a female with testes but no internal sex organs
lordosis
stage 1 of female rodent sexual behavior
exposes genitals
receptivity
step 2 of female rodent sexual behavior
appearance of changes in gonads
step 3 of female rodent sexual behavior
proceptivity
step 4 of female sexual behavior
attractiveness
what are the 3 steps of male rodent sexual behavior?
Intromission
pelvic thrusting
ejaculation
male sexual behavior requires which 2 hormones?
testosterone and estrogen
accessory olfactory bulb
pheromones
Vomeronasal organ (VNO)
Pheromones
Lee-Boot
estrous ceases in groups of females
Pheromones
Whitten
male urine reinstates estrous
Pheromone
Vanderburg
male urine speeds onset of puberty
Pheromone
Bruce
new male (competing male) urine aborts pregnancy
androstadienone (AND)
human pheromone that increases attractiveness to males (found in male sweat)
estratetraenol (EST)
human pheromone increases attractiveness to females (found in female urine)
medial preoptic area
major role in male sexual behavior
- contains testosterone receptors
sexual activity increases or decreases dopamine release within medial preoptic area
increase
brain region most involved with female sexual activity
ventromedial hypothalamus
neural control of maternal behavior
medial preoptic area
fleming found that which two chemicals were most responsible for a fathers role in infant care
prolactin and oxytocin
