Document Summary
Neurons and glia (cells that make up the brain) Neuron (piece of tissue of the cell) Neural membrane (skin = think of our skin) &cytoskelelton provides the neuron"s shape (think of our bones) Along this membrane is where we get changes in potential. Components : cell body (soma), axon, dendrites (coming off the cell body) Ion chanels ions can only go through ion chanels sometimes they"re closed and sometimes they"re open, sometimes they"re specific letting certain ions to come through and others not to come through different ion channels on a neuron membrane. Phospholipid layers on neuron membrane studed with proteins. We have ion pumps difference btwn this and the channels, is that channels allow if you have more ions than on inside there needs to balance. Ion channels focus on concentration inside and outside. Pumps are different and require energy and they pump out and in against the ion concentration.
