T or F: Potassium ions are at high concentrations inside of cells, including neurons - ANSWER-True The action potential is a result of: - ANSWER-the movement of ions The post-synaptic cell can be: - ANSWER-in glands, muscle cells and neurons Th resting potential of a neuron is - ANSWER--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 - ANSWER-false T or F: Voltage gated ion channels open when a protein binds ...

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - ANSWER TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. - 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 glial cells (i.e., m...

T or F: Potassium ions are at high concentrations inside of cells, including neurons correct answer: True The action potential is a result of: correct answer: the movement of ions The post-synaptic cell can be: correct answer: in glands, muscle cells and neurons Th resting potential of a neuron is correct answer: -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 correct answer: false T or F: Voltage gated...

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...
