Question

multiple choice question
what is the background activity of both the sympathetic and parasympathetic divisions of the ans called?
o muscle tone
o vasomotor tone
o somatic tone
o autonomic tone

Explanation:

• Muscle tone: Refers to the state of tension in a muscle, not related to the ANS (Autonomic Nervous System) background activity.
• Vasomotor tone: Specifically related to blood vessel tone, not the general background activity of both ANS divisions.
• Somatic tone: Pertains to the somatic nervous system, not the ANS.
• Autonomic tone: The ANS (Autonomic Nervous System) has both sympathetic and parasympathetic divisions. In most organs, there is a background activity from both divisions. This background activity is called autonomic tone. It allows a fine - tuning of organ function. For example, in the heart, both divisions have a basal level of activity that can be adjusted up or down depending on the body's needs.

Answer:

Autonomic tone
