Gamma motor neurons play a crucial role in regulating muscle tone and sensitivity to stretch by adjusting the sensitivity of the muscle spindle.

Gamma motor neuronsMultiple Choiceare located in tendons.transmit action potentials to skeletal muscle.regulate the sensitivity of the muscle spindle.enable the brain to perceive that a muscle has been stretched.innervate the whole muscle.

Muscle spindlesMultiple Choiceare innervated by gamma motor neurons.originate in the spinal cord.are specialized nerve cells.are found encapsulated in nerve endings.are innervated by alpha motor neurons.

List the two ways that motor neurons regulate motor units to develop force in a muscle

Order the steps involved in the activity of a muscle spindle:Muscle spindle is stretched.Reflex action occurs.Contraction of muscle fibers adjoining the muscle spindle.Nerve signals are generated.The muscle relaxes.The muscle's length increases.Multiple Choice1,6,2,4,5,32,3,1,4,5,65,6,1,4,2,32,1,6,3,4,55,1,2,4,3,6
