Solution

The correct option is D Adrenaline and Noradrenaline
Adrenaline, along with noradrenaline, is largely responsible for the immediate reactions we feel when stressed. The adrenal medulla receives neural input from axons of the sympathetic division of the autonomic nervous system, and it secretes epinephrine (adrenaline) and norepinephrine (noradrenaline) in response to stimulation by these axons. The actions of these hormones trigger “alarm” responses similar to those elicited by the sympathetic division, helping to prepare the body for “fight or flight.” Among the effects of these hormones are an increased heart rate, increased blood pressure, dilation of the bronchioles, elevation in blood glucose, and reduced blood flow to the skin and digestive organs. The actions of epinephrine released as a hormone supplement those of norepinephrine released as a sympathetic nerve neurotransmitter.
