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.

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

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.

Many upper motor neuronsMultiple Choiceare responsible for planning involuntary movements.directly innervate skeletal muscles.are located in the primary motor area.control smooth muscle.have cell bodies in the spinal cord.

The Golgi tendon organs monitor tension produced by muscular contraction. detect the length of the muscle fiber. activate gamma motor neurons. detect the position of joints during movement.

Group 1a primary afferent neurons (sensory neurons) from muscle spindles primarily encode which type of information?Group of answer choicesthe angle of the associated limb, relative to its motor inputthe tension of the muscle, relative to its motor inputthe absolute tension developed by the musclethe absolute length of the musclethe length of the muscle, relative to its motor input PreviousNext
