A

Pacemaker cells increase heart rate

Myocytes increase strength of contraction

3
Q

Sympathetic reaction on lungs

A

Smooth muscle relax dilates airways

4
Q

Smooth muscle relax corpus cavernosum causing an erection

19
Q

What are these processes controlled by?

A

Autonomic reflexes

Central control from the hypothalamus
