Neuron: Basic Structure

1
Neuron Basic Structure

• Dendrites
• receive messages from other neurons

2
Neuron Structure

• Myelin Sheath
• wrap themselves around the axon providing a
  protective coating

• Axon
• Carries messages destined for other cells

3
SYNAPSE

• AXON TERMINAL
• SYNAPTIC SPACE
• SYNAPSE
• SYNAPTIC VESICLE
• RECEPTOR CITE

4

• Neurotransmitters
• Chemicals that carry messages across the synapse
  to the dendrite (and sometimes the cell body) of
  a receiver neuron

• Synapse
• A chemical connection that bridges the gap
  between two neurons

5

• Excitatory messages
• A chemical secretion that makes it more likely
  that a receiving neuron will fire and an action
  potential will travel down its axon.

• Inhibitory Messages
• A chemical secretion that prevents a receiving
  neuron from firing
