Document Summary
If it is damaged, there could be a loss of sensation, a loss of coordination. It is also a reason that a baby is so uncoordinated because the myelin sheath is not fully developed in the baby. Speed: message ends at synapse, terminal button, synaptic cleft, receptor site of the next neuron, connection to the other neuron. 4: when no information is being communicated we call it the resting. Potential : when they are communicating, it comes out of rest. If the message is sent, the neutrons create action potential : permeability is changed so that positive ions flow in. Refractory period = down time required before another firing. All or none = neurons fire or not. Strength is communicated via speed of firing: the action potential arrives at the terminal button. Therefore, synaptic vesicles release info (neurotransmitters: only the right shaped message (neurotransmitter) can be received (lock and key) Binding of n. t to receptor site post synaptic.
