ASU Bio 181 Quiz 4 Latest Update Graded A+ (T/F) Acetylcholine esterase breaks acetylcholine into muscarinic acid False (T/F) Acetylcholine exocytosed from the presynaptic cell travels to the postsynaptic cell to start the action potential in the postsynaptic cell. True (T/F) Excitatory synapses cause depolarization of the post-synaptic cell. True (T/F) Excitatory synapses cause hyperpolarization of post-synaptic cells. False (T/F) Excitatory synapses make the post-synaptic ce...

BIO 235 Final Exam Questions With 100% Correct Answers 2024/2025 Potassium: A. is more abundant outside the cell than inside the cell. B. moves into the cell during an action potential. C. is transported out of the neuron by the sodium-potassium pump. D. leaks out of the cell more than sodium leaks into the cell. - answerc. salutary and continuous action potential conduction - answerconduction occurs in myelinated axons. Nerve signals transmit much faster than in continuous conduction be...

Excitatory synapses make the post-synaptic cell less likely to fire. - ANSWER-False The neural tissues are: - ANSWER-Spinal cord, sensory neurons, and brain How do the glial cells (i.e., myelin sheath) speed up the firing of neurons? - ANSWER-The cell wraps extensions of a fatty insulating substance (myelin) around the axons of neurons. The action potential is: - ANSWER-A result of the movement of ions. Receptors are made from membrane-bound polyribosomes. - ANSWER-True List the 4...
