BIO 181 (Capco ASU) Exam 3 (Final Exam)

BIO 181 (Capco ASU) Exam 3 (Final Exam) T/F Excitatory synapses cause hyperpolarization of post-synaptic cells. - CORRECT ANSWER-False The resting potential of neurons is: - CORRECT ANSWER--60 mv (The answer is not on this list.) T/F The autonomic nervous system contains the sympathetic and the parasympathetic nervous system. - CORRECT ANSWER-True In the motor end plate, the event that is the immediate trigger for exocytosis is: - CORRECT ANSWER-Calcium Ions Draw an action potential in the axon of a neuron and indicate which ions flow into the neuron and out of the neuron as the action potential passes at the point where the electrodes are in the cell. Be sure to assign on the Y-axis the mV of each of these areas. This should be as described in my lectures. - CORRECT ANSWERThe action potential is: - CORRECT ANSWER-A result of the movement of ions. T/F The cell body refers to the part of the neurons that begin at the dendrites and extend to the axon terminal. - CORRECT ANSWER-False T/F When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - CORRECT ANSWER-True The post-synaptic cell can be: - CORRECT ANSWER-In glands, muscle cells, neurons T/F Excitatory synapses cause depolarization of the post-synaptic cell. - CORRECT ANSWER-True T/F Only pre-synaptic neurons are coated with myelin. - CORRECT ANSWER-Fa
