Transcript of The Neuron Dendrites Cell body (perikaryon, soma)
Myelinated axons: sheath of Schwann and myelin sheathone Schwann cell myelinates a single axonmultiple Schwann cells needed to cover entire length of an axon
Transmission1. innervation
- cell body as integrator2. action potentials (impulses)
- axon hillock3. myelin sheath
Synapses- presynaptic terminal- postsynaptic terminal- neurotransmitters- ligand-gated ions channels on postsynaptic membrane
