ASU BIO 181 Exam 3: Q&A Complete Study Guide

ASU BIO 181 Exam 3 Study Guide 2023 Questions with Answers (Verified) The post-synaptic cell can be: - ANSWER In glands, muscle cells, neurons T/F Excitatory synapses cause depolarization of the post-synaptic cell. - ANSWER True T/F Only pre-synaptic neurons are coated with myelin. - ANSWER False T/F Fast neurons as described in lecture are fast because they are surrounded by a type of glial cell that results in a myelin coating. - ANSWER False T/F The axon from a pre-synaptic cell contac...

ASU BIO 181 Exam 3 Study Guide 2023 (Questions with Answers 100% Correct) T/F Excitatory synapses cause hyperpolarization of post-synaptic cells. - ANSWER False The resting potential of neurons is: - ANSWER -60 mv (The answer is not on this list.) T/F The autonomic nervous system contains the sympathetic and the parasympathetic nervous system. - ANSWER True In the motor end plate, the event that is the immediate trigger for exocytosis is: - ANSWER Calcium Ions Draw an action potential in...

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. correct answer: TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. correct answer: During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glia...
