ASU BIO 181 Exam 3 Questions and Answers 100% Verified The autonomic nervous system contains the sympathetic and trie parasympathetic nervous system. - answerTrue Potassium ions are at high concentrations inside of cells including in neurons. - answerTrue The post-synaptic cell can be: - answerIn glands, muscle cells, neurons The axon hillock in the pre-synaptic neuron fires based on temporal and spatial summation of inputs. - answerTrue Only pre-synaptic neurons are coated with myelin. - answerFalse The axon from a pre-synaptic cell contacts the axon of another neuron. - answerFalse Acetylcholine esterase breaks acetylcholine into muscarinic acid - answerFalse Excitatory synapses cause depolarization of the post-synaptic cell. - answerTrue The action potential is: - answerA result of the movement of ions Fast neurons as described in lecture are fast because they are surrounded by a type of glial cell that results in a myelin coating - answerFalse The central nervous svstem (CNS) contains: - answernone of the answers are correct The neural tissues are: a. Spinal cord, sensory neurons, and cell body b. Spinal cord, sensory neurons, and brain c. Brain, and sensory neurons d. Pituitary and hypothalamus e. None of the above - answerSpinal cord, sensory neurons, and brain In the motor end plate, the event that is the immediate trigger for exocytosis is: - answerCalcium Ions The membrane potential (resting potential) is largely set by the Na-K-ATPase pump. - answertrue The cell body refers to the part of the neurons that begin at the dendrites and extend to the axon terminal. - answerfalse Acetylcholine exocytosed from the presynaptic cell travels to the postsynaptic cell to start the action potential in the postsynaptic cell. - answertrue Fast neurons as described in lecture require cytoplasmic signal transduction to open an ion channel. - answerFalse Excitatory synapses cause hyperpolarization of post-synaptic cells. - answerfalse
