Neurotransmitter-Response

The reaction of a cell to the binding of neurotransmitters, which can alter the cell's activity or provoke a series of cellular events.

Skeletal Muscle Contraction

The process by which skeletal muscles, attached to bones, produce movement through the shortening of muscle fibers, using ATP as energy.

Dopamine

A neurotransmitter involved in many functions including mood, sleep, learning, and the regulation of body movements, often associated with the pleasure and reward system of the brain.
