Document Summary

Efferent neurons send info back to lift foot up. Many types of receptors work together to achieve body movement that one wants. Invitro recording/preparation ( taking a cell and keeping it alive in a dish) If you cut the soma and dendrites you wouldn"t be able to transmit any information. Every cell has a resting potential ( a voltage generated across the cell membrane) most basic physiological aspect of a neuron. Membrane potention- when you measure voltage across the membrane. Excitatory or inhibitory and action potential can disrupt resting potential. If you can separate the charges there is voltage ( action potential) Charged particles flow in and out of membrane. Ions that flow in and out could depolarize a neuron. Origin of membrane resting potential (includes last 3 bullets) Ions- atoms that have gained or lost electrons. Charge/some unit of time = current (sodium current going into the membrane) The consequence, the voltage is changing ^ in this case depolarization.
