10. Types of Neurons
Kinesiology Books Publisher

11. The Neuron’s Function Receptive segment (dendrites)
Receives continuous synaptic input (chemical) from other neurons
Conductive segment (axon)
Conduction of neural information in the form of nerve impulses (electrical)
Transmissive segment (axon terminals)
Converts electrical nerve impulse to chemical form (neurotransmitter) and sends it off to synapse
Conductive
Transmissive
