Both sympathetic and parasympathetic divisions are tonically active, which means theyQuestion 11Select one:a.continually conduct impulses to the brain.b.are hydrolyzed by the enzyme acetylcholinesterase.c.continually conduct impulses to autonomic effectors.d.have opposing effects.

The correct answer is c. Both sympathetic and parasympathetic divisions are tonically active, which means they continually conduct impulses to autonomic effectors.

Here's why:

Tonic activity refers to the continuous or baseline level of activity in neurons. In the context of the autonomic nervous system (which includes the sympathetic and parasympathetic divisions), this means that these systems are always sending signals to the body's organs and tissues, even when there is no specific stimulus triggering a response.

The sympathetic and parasympathetic divisions often have opposing effects - the sympathetic division is often associated with "fight or flight" responses (like increasing heart rate), while the parasympathetic division is often associated with "rest and digest" responses (like slowing heart rate). However, both are continually sending signals to the body's organs and tissues, adjusting their activity levels as needed based on the body's needs.

So, the statement "Both sympathetic and parasympathetic divisions are tonically active, which means they continually conduct impulses to aut
