c. thoracolumbar origin, short preganglionic fiber, ACh release at ganglion, long postganglionic fiber, NE release at effector
d.craniosacral origin, long preganglionic fiber, ACh release at ganglion, short postganglionic fiber, ACh release at effector

Answer 1

Answer is C.

Step-by-step explanation:

The sympathetic pathway is the pathway of the sympathetic nervous system. Sympathetic nervous system is a part of the autonomic nervous system , that comprises of neurons regulating the body's involuntary actions. It is also regarded as the pathway by which organisms respond to stress, because it prepares the body for stress.

The sympathetic nervous system help the body to respond to stress by increasing the rate of the heart beat, activating the release of adrenaline among others.

The other part of the autonomic nervous system is the parasympathetic nervous system, which brings the body to the state of calmness and relaxed feeling after a stressful event. This is done by slowing down the heart rate and increasing the rate of digestion.
