Document Summary
Nervous system study guide: list the functions of the nervous system, to receive information from the environment both external and internal by specialized receptor cells. In a resting membrane potential the sodium gates are closed and there are some potassium gates open: sodium stays outside the cell, while potassium is diffusing out. As a result there more positive ions outside the membrane compared to the inside: discuss how an action potential is generated and travels down a membrane to the synaptic bulb. As a result adjacent membrane sections have opposite charges (which are still negative on the inside). This occurs for a split second and the membrane polarizes again while the adjacent membrane section depolarizes. If there is sufficient amount of neurotransmitters binding to receptors, it is able to cause more sodium gates opening to trigger an impulse along that neuron: draw and label a typical neuron and include the following componenets: Nucleus, dendrites, axon, myelin sheath, vesicles with neurotransmitters.
