Answer:
e. All of the choices describe characteristics of the ANS.
Explanation:
The autonomic nervous system is a regulatory and control system that influences the functions of internal organs.
Autonomic pathways consist of two types of motor neurons, these are the preganglionic neuron and the postganglionic neuron.
ANS stimulation of involuntary effectors is always excitatory. In the preganglionic autonomic neurons, and all postganglionic parasympathetic neurons are usually (cholinergic i.e receptors that bins with acetylcholine), as a result they release acetylcholine as a neurotransmitter. The cholinergic effects of preganglionic autonomic neurons are always excitatory.
The postganglionic neuron lies entirely in the peripheral nervous system.Yes!, this is so because the ganglion cells that give rise to postganglionic axons lies through the gray rami communicans and join the peripheral nerves of the peripheral nervous system.

Carbohydrates often receive negative attention as the dieter's enemy. Yet the American Dietetic Association argues that they should be your main source of energy, accounting for 45 to 65 percent of your total daily calories. That's because carbs are your body's quickest fuel source, ultimately yielding the simple sugar glucose. Glucose fuels metabolic reactions throughout your body and is the only form of energy that your brain can use.
