The main neurotransmitter for synapses is _ which lies outside the CNS.
Correct answer: C. Acetylcholine
- A. Choline
- B. Acetoldehyde
- C. Acetylcholine
- D. Phosphatidylcholine
Explanation
Acetylcholine is the main neurotransmitter for synapses that lie outside the central nervous system (CNS). It is released at neuromuscular junctions, which are synapses between motor neurons and muscle cells in the peripheral nervous system. Acetylcholine is responsible for transmitting signals from motor neurons to muscles, leading to muscle contraction.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
