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.

Upper motor neuronsGroup of answer choicescontrol the upper half of the torso.synapse on muscles in the eye, neck, and head.synapse on local circuit neurons and/or lower motor neurons.affect motor patterns only indirectly via their inputs to the basal ganglia.have cell bodies that are located in the ventral horn of the spinal cord.

Select which steps are part of the voluntary movement process. Select all that apply.Multiple select question.Lower motor neurons receive messages from upper motor neurons.The cerebellum and basal nuclei coordinate the information for these movements.Smooth muscle in the skin is stimulated to contract.Initiation begins in the primary motor area of the cerebral cortex.Initiation begins in the brainstem.Upper motor neurons receive information from lower motor neurons.

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.

Where are the cell bodies of lower motor neurons of the upper limb located?

Select all correct descriptions of the motor pathways within the somatic division of the peripheral nervous system.Multiple select question.Effectors are skeletal muscles.Control is always involuntary.Fibers are carried by most cranial and all spinal nerves.Two neurons carry messages.The neurotransmitter is acetylcholine.
