Most likely A from my point of view
<span>Cell bodies of preganglionic neurons reside in the brain stem or spinal cord. Preganglionic neurons stimulate postganglionic neurons.</span>
Electrolytic cell is the type of a cell in which current drive a non-spontaneous redox reaction. Redox reactions are reactions in which the oxidation number of the reactants are changed. To change oxidation number, electrons must either be added to or removed from the reactants. However, to observe the law of conservation of mass, all the electrons removed from one reactant or atom must be added to another one, therefore, the number of species lost by one substance is equal to the number of electrons gained by the other.
Answer:
If you tap your knee, the signal to act is carried via your somatic nervous system to the muscles in your knee. In contrast, the signals that pass via the autonomic nervous system are involuntary and act primarily to regulate your body's internal environment. This involuntary nerve system is further organized into three divisions. If you need a sudden burst of energy, your sympathetic nervous system is activated to help you act quickly. In contrast, if you are relaxing and conserving energy, then it is your parasympathetic nervous system that is primarily in action. The third division is your enteric nervous system which helps control the components of the digestive system.
Explanation:
Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:
- somatic (voluntary) nervous system-controls the movements of the skeletal muscles
- autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
- sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions)
- parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
- enteric nervous system-controls the function of the gastrointestinal tract.
