1. What are an afferent neuron and efferent neuron? What are efferent components of the facial nerve and their actions? 2. Under certain circumstances, axons in the peripheral nervous system can regenerate after sustaining damage. Why is axonal regeneration in the central nervous system much less likely? 3. At a healthy myoneural junction, acetylcholine is responsible for stimulating muscle activity. What mechanisms are in place to prevent the continuous stimulation of a muscle fiber after the neurotransmitter is released from the presynaptic membrane?
7. Which option is correct
T or F. Motor signals originating in the cortex can't interfere with motor reflex response? T or F. Reflex functions are exclusive only for responses within the level of the spinal cord? T or F. Internuerons can simultaneously inhibit the transmission of nerve impulses into the antagonistic muscle on the ipsilateral side of the body and to the same muscle on the contralateral side of the body?
