各位大大,
想問下 hypothalamus 用咩黎控制 release of adrenaline and thyroxine ga? 恐龍書話send nerve impulse to thyroid gland to increase metabolic rates,
mastering 嗰本textbook又話用TRH同TSH黎stimulate the glands to release the hormones

究竟邊個先岩???? 我望唔透, 跪求大大幫手解答

Adrenaline同thyroxine係兩樣野，分清楚好啲喎

Thyroxine:
Hypothalamus secrete TRH.
TRH stimulate anterior pituitary gland to secrete TSH.
TSH stimulate thyroid gland to secrete thyroxine.

Adrenaline:
Sympathetic nerve send nerve impulse to adrenal medulla to secrete adrenaline.
