- Lub adrenal qog. Tsim 4 hom ntawm cov tshuaj hormones: corticosterone, epinephrine, norepinephrine, thiab pw ua ke cov tshuaj hormones. Corticosterone cuam tshuam feem ntau metabolic dab. Norepinephrine - excitation neurotransmitter nyob rau synapse, thiab epinephrine ua yuav luag zoo li lub sympathetic lub paj hlwb.

- txiav. Nws lub ntsiab cov tshuaj hormones - glucagon thiab insulin. Glucagon muaj feem xyuam rau cov hloov dua siab tshiab ntawm glycogen rau piam thaj, thiab cov kua dej los ua num ua ke nrog cell week, kom lawv permeability rau piam thaj.
