Summary Introduction
Introduction:
When a person blushes, the face, especially the cheek areas become red. This happens due to the gushing of the blood in that region. The flow of the blood is an involuntary response of the autonomous nervous system (ANS) when the person is under stress.

A woman is lifting weights. She is able to lift 20 kg fairly easily. She then attempts to
lift 35 kg, but it requires a bit of effort.
A) What type of nerve has she activated in order to lift the weights?
B) Provide two approaches that her muscular system could use to generate more
muscle tension.
Regulation by the nervous system provides, (a) relatively slow but long-lasting responses to stimuli. (b) swift, long-lasting responses to stimuli. (c) swift but brief responses to stimuli. (d) relatively slow, short-lived responses to stimuli.
