Bio 181 ASU Exam 3 Solved 100% Correct!! T or F: Potassium ions are at high concentrations inside of cells, including neurons True The action potential is a result of: the movement of ions The post-synaptic cell can be: in glands, muscle cells and neurons Th resting potential of a neuron is -60mV T or F: The cell body refers to the part of the neurons that begin at the dendrites and extend to the axon terminal false T or F: Voltage gated ion channels open when a protein binds to the...

BIO 181 (Capco ASU) Exam 3 (Final Exam) Already Graded A+ T/F Excitatory synapses cause hyperpolarization of post-synaptic cells. False The resting potential of neurons is: -60 mv (The answer is not on this list.) T/F The autonomic nervous system contains the sympathetic and the parasympathetic nervous system. True In the motor end plate, the event that is the immediate trigger for exocytosis is: Calcium Ions Draw an action potential in the axon of a neuron and indicate which ions flo...
