Psychology Exam 3

4 carbon rings, derive from cholesterol 1. bind to membrane receptors 2. enter cells & activate protein 3. bind to chromosomes, activate/inactiveate certain genes

Control most diff btw male/female

Apoptosis-causing certain areas to b slightly larger in males/females

Alters expression of genes on other chromosomes

@ sensitive stage-determine male/female permanent structural diff to develop gradually

@ any time in life, temporary behavior change, don't last forever, early life=temp puberty=long lasting change & activing effects effect lasts longer than hormone remains in organ

Begins w chromosomes depends on level of testosterone-sensitive pd 3-4 months of pregnancy

Both male/female have a set of mullerian & wolffian ducts & gonads (testes/ovaries)

Sex determining region on male y chromosome, develop into testes testosterone-causes wolffian ducts to develop seminal vessicles & vas defferens MIH-hormone causes degeneration of mullerian ducts

Develop from 1 biological precursor

Develop normal parts but not normal sexual behavior, more important for interal anatomy not external

Female!

Bind to receptors in specific areas of hypothalamus & amygdala

Anterior hypothalamus, larger in male than females--male sexual behavior female hypothalamus=cyclic hormone pattern, males cannot do this

Alpha-fetoprotein=in rats, during sensitive pd, not present in adults, binds w estradiol & prevents it from affecting fetus. THis is why females aren;t masculinized by own estradiol
