Discussion
............................. gland is responsible for emotional arousal.
Answer: A
The gland is the adrenal gland.
In emotional arousal, the 'fight or flight' response, the adrenal medulla releases adrenaline and noradrenaline. These hormones raise the heart rate, blood pressure, breathing rate and blood sugar, producing the bodily state of arousal that accompanies fear, anger and excitement before competition.
The thyroid controls the basal metabolic rate and the pancreas blood sugar through insulin and glucagon; neither produces the emergency response. The hypothalamus in the brain sets the response going through the sympathetic nerves, but the hormones that produce the aroused state come from the adrenal glands.
