Document Summary
They are the only cells that can send information (neural signal) over long distances in brain and body: 2. They are the only cells that have long cord like pairs called axons which vary in length: 3. Terminal nodes= where action potential arrives prior to release of neurotransmitters into the synapses: post synaptic membrane of a neuron: receiving side of the synapse; job is to receive neurotransmitters from other neurons xi. Pre synaptic membrane of a neuron: sending the electrical signal/action potential xii. Propagation: electrical neural signal forced to travel quickly in 1 direction down axon xiii. Potential: voltage/electrical level: types of potentials, 1. Kept at peak strength no signal weakening over a period of time as it travels down the axon xi. Salutatory conduction: ap skipping under the myelin sheath + regenerating the ap"s voltage levels at the node of ranvier through ions being exchanged through ion channels on the exposed axon membrane xii.
