Answer:

The correct answer is B: Acetylcholine is secreted from the neuron that originates in the CNS.

Explanation:

The nervous system is divided into:

  • The somatic motor system, which regulates skeletal muscle contraction
  • The autonomic nervous system, which is also divided into sympathetic, parasympathetic and enteric system, and its main function is to regulate internal organs functioning. Also, sympathetic has a key role in the “fight or flight” response.

Although these two systems have different functions, they work with the same neurotransmitter, which is acetylcholine.  

Acetylcholine is produced on CNS neurons and its effects depend on the activation of nicotinic and muscarinic receptors that are located in pre and post synapsis.  

Muscarinic receptors are G-protein coupled receptors and nicotinic receptors are polypeptide receptors associated to ion channels

The similarity between the somatic motor and autonomic pathway is the presence of acetylcholine that is secreted from the neuron that originates from the central nervous system.

The Nervous system

The central nervous system is the major parts of the human nervous system that consists of the brain and the spinal cord.

Acetylcholine is a very important neurotransmitters secreted by neurons of the central nervous system but acts on both the autonomic pathway and somatic motors.

Both the autonomic pathway and somatic motors releases acetylcholine at the effector sites, hence the similarity.
