Explanation
Acetylcholine is a neurotransmitter involved in both the central and peripheral nervous systems. It plays a key role in muscle contraction, memory, learning, and attention. In the central nervous system, acetylcholine is important for cognitive functions, while in the peripheral nervous system, it enables communication between nerves and muscles. Low levels of acetylcholine are associated with conditions like Alzheimer's disease.

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.
