Factors that affect conduction rates (myelination, axon diameter & temperature)

By: HWC, Views: 7854

• Several factors determine the rate of conduction of action potentials: • Myelination • Axon diameter • Temperature • The step-by-step depolarization of an axon is called continuous conduction and occurs along unmyelinated axons. • Neurons in the PNS have many axons that ...

Neurotransmission at chemical synapses & Excitory and inhibitory potentials

By: HWC, Views: 7645

• A series of events occur at chemical synapses in order to communicate with the adjacent cell. • The action potential arrives at the presynaptic membrane. • The depolarization phase of the action potential opens voltage gated Ca+ channels. • increased inflow of Ca+' into the cyto...
