Question

Gabe's wife wakes him from his peaceful slumber to tell him she heard a noise. As he slowly gets up to investigate, his heart begins to race, his mouth is dry, and he begins to sweat. Clearly his _____ nervous system has been activated.

Answer 1

Answer: Clearly his SYMPATHETIC nervous system has been activated.

Explanation:

The effects of the sympathetic nervous system dominate in times of EMERGENCY or STRESS. And its effects include:

- dilation of pupils to help Gabe see sharply as he investigate

- inhibition of saliva secretion as his mouth turns dry

- acceleration of heartbeat due to fear

- stimulation of sweat glands to produce sweat.

All these show clearly that Gabe's SYMPATHETIC nervous system has been activated.
