Document Summary
Hypothalamic - pituitary - adrenal (hpa) axis. Adrenal glands androgens, epinephrine (adrenaline), & cortisol. Gonadal glands estrogens (estradiol) & androgens (testosterone ) Androgens produced by gonads are much stronger than those from hpa axis. Adrenarche in middle childhood (starts ages 5 - 9; can continue into 20s ) Hpa - axis androgens secondary sexual characteristics. Hypothalamic - pituitary - gonadal (hpg) axis. Gonadotropin - releasing hormone (gnrh) - luteinizing hormone (lh) & follicle - stimulating hormone (fsh) Testes produce sperm & testosterone spermarche. Ovaries produce ova & estradiol menarche. *** white matter continues to rise going into adulthood pruning) Gray matter peaks in middle childhood & then decreases afterward (reflects synaptic. Limbic system (fear, emotional impulses, episodic memories ) Prefrontal cortex (executive functions, self - regulation) Develops into mid - to - late 20s. Emotion regulation ( top - down control) matures into adulthood. Merges research on adolescent brain & pubertal development.
