Definitions:

Neurotransmitter

Chemicals released by neurons to transmit signals across a synapse to another neuron, muscle cell, or gland.

Calcium Channel

Calcium channels are protein-based channels within cell membranes that selectively allow calcium ions to move into or out of a cell, playing critical roles in various physiological processes including muscle contraction, neurotransmission, and gene expression.

Myelin Sheath

A fatty layer that surrounds nerve fibers, providing insulation and increasing the speed of electrical transmission along the neuron.

Receptor

A protein on the surface of a cell or inside it that binds to specific molecules, triggering a specific effect in the cell, such as a response to hormones or neurotransmitters.
