How do sensory neurons differfrom motor neurons? I. Sensoryneurons carry impulses from thereceptor to the brain while motorneurons carry impulses from thebrain to the effector. II. Sensoryneurons carry impulses from thebrain to the effector while motorneurons carry impulses from thereceptor to the brain. II. Sensoryneurons carry impulses triggeredby stimulus from the organ to thebrain while motor neurons carryprocessed information from thebrain to the organ to response. IV.Sensory neurons carry processedinformation from the brain to theorgan to response while motorneurons carry impulses triggeredby stimulus from the organ to thebrain. *O I and III onlyO Il and IV onlyO I and IV onlyO Il and III only

Potassium can freely enter the cell to depolarize it c. Chloride can freely exit the cell to depolarize it d. GABA receptors become blocked, preventing proper suppression e.

What is the function of the presynaptic “autoreceptors" in axon terminals? a. To release substances into the blood O b. To detect transmitter concentrations in the cleft O. To release neurotransmitters into extracellular fluid d. To release the neurotransmitter acetylcholine
Researchers have designed a neuron that's unable to produce and release neurotransmitters. Can that neuron still have an action potential? Choose the answer with the correct answer and the correct reasoning. O No, action potentials need neurotransmitters to increase message speed O No, a neuron can't receive messages without its own neurotransmitters O No, a lack of neurotransmitters would leave a neuron unmyelinated O No, action potentials don't occur in the axon O Yes, action potentials don't require neurotransmitters:
The reflex arc is the fastest way the body has to move a body part from danger or away from the source of pain. Have you ever noticed your own reflex response? Did you notice that you felt the pain after you yanked your hand away from the source of pain? Which is the sequence of structures involved in a reflex response? a. motor neurons → effectors → brain → sensory neurons → interneurons b. effectors → sensory neurons → brain → motor neurons c. sensory neurons → interneurons → motor neurons → effectors d. sensory neurons → motor neurons → interneurons → effectors
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?
