Definitions:

Muscle Spindle

Muscle spindles are sensory receptors within the belly of a muscle that primarily detect changes in the length of the muscle, thereby helping to regulate muscle contraction.

Action Potentials

Rapid rises and falls in the membrane potential of a cell, fundamental in the conduction of electrical impulses along nerves and muscle fibers.

Sensory Neurons

Neurons that transmit signals from sensory receptors towards the central nervous system, carrying information about external or internal conditions.

Gamma Motor Neurons

Neurons that control the contraction of intrafusal muscle fibers in muscle spindles, helping to regulate muscle tone and sensitivity of stretch reflexes.
