question 24

Multiple Choice

What is the best description of how a given muscle fiber can be inhibited from contracting?

• A) Inhibitory inputs from local reflexes and descending pathways prevent the fiber's motor neuron from firing action potentials.
• B) Descending inputs from brainstem components of the middle level of the motor control hierarchy make inhibitory synapses onto the muscle fibers.
• C) Contractions in an antagonistic muscle's fibers are stronger than the given muscle's contractions.
• D) Golgi tendon organs send afferent neurons directly to muscle fibers that attach to them and release inhibitory neurotransmitter.
• E) Interneurons in the local spinal cord region send axons to the muscle fiber's neuromuscular junction, where they impose presynaptic inhibition.
