Endocrine System and Nervous System in Action! Brain detects stress Brain sends motor neuron to adrenal glands Adrenal glands release adrenaline (epinephrine) Adrenaline travels through blood to target cells Causes increase in breathing, eyes dilate, heart pumps faster

Increase in heart rate, increase breathing, dilate eyes adrenaline
