Classify the following neurons as bipolar, multipolar, unipolar and if it represents a sensory, motor, or interneuron. What is an potential”? “action What was the purpose of doing the Reaction Time experiments? What was the purpose of doing the knee jerk reflex experiment? Label the reflex arc with: sensory neuron, motor neuron, effector, spinal cord Why is the reflex arc important to homeostasis? How is the reflex arc different from seeing a stimulus and having to process it? Put the following statements in the correct order of events that happens during a reflex arc. Put the correct number,1-8 , in the blanks provided. Membrane depolarizes to threshold. Voltage-gated Na+ channels open and Na+ enters the cell. _______ _______ The cell returns to resting ion permeability and resting membrane potential. _______ K+ moves from cell to extracellular fluid (the cell is depolarizing). _______ Rapid Na+ entry depolarizes cell. _______ Resting membrane potential _______ Na+ channels close and slower K+ channels open. _______ Depolarizing stimulus _______ K+ channels remain open and additional K+ leaves the cell, hyperpolarizing it.
