Neurons and Nervous System

Typical Neuron Structure Terms you need to locate: Dendrite Myelin Cell Body Axon Axon Ending (aka Axon Bouton)

Functions of a Neuron rapid transmission of neural signals the integral element of our five senses, physical ability, regulatory system, and mind receive nerve signals (action potentials) integrate action potentials transmit these signals to other neurons or organs rapid transmission of neural signals

Four Neuron Types

Basic Steps of a Neuron

Neurotransmission Step-wise Nerve cell sends electrical signal along axon Axon carries electrical signal Myelin sheath protects axon Signal travels to synaptic knob or Axon Ending Neurotransmitter crosses synapse Receptor Cells are activated
