Acetylcholine is responsible for the hyperpolarization of the sinoatrial node.

The definition of hyperpolarization?

At a specific location on the neuron's membrane, hyperpolarization occurs when the membrane potential increases, and depolarization occurs when the membrane potential decreases (more positive).

Explain the membrane of a neuron:

Most activities involved in maintaining and functioning of neurons are started at the neuronal membrane. Membrane-related molecular agents, which interact in protein/lipid clusters to start molecular processing and signal transduction, are required for these processes.
