  1. Neuron Anatomy

  2. Neuron Dendrites: (dend = tree) cell processes that carry electric impulses from an incoming nerve to a cell body. Hundreds per neuron.

  3. Neuron Dendrites: (dend = tree) cell processes that carry electric impulses from an incoming nerve to a cell body. Hundreds per neuron. Cell body: Contains nucleus, cytoplasm, and organelles. Metabolic center of a cell.

  4. Neuron Dendrites: (dend = tree) cell processes that carry electric impulses from an incoming nerve to a cell body. Hundreds per neuron. Axon: Cell process that carries electric signals away from the cell body. Up to 3-4 ft. long. Cell body: Contains nucleus, cytoplasm, and organelles. Metabolic center of a cell.

  5. Neuron Dendrites: (dend = tree) cell processes that carry electric impulses from an incoming nerve to a cell body. Hundreds per neuron. Axon: Cell process that carries electric signals away from the cell body. Up to 3-4 ft. long. Schwann cells: made of fat, wrap around axon to form myelin insulation. Increases the speed of nerve conduction, like insulation. Cell body: Contains nucleus, cytoplasm, and organelles. Metabolic center of a cell.

  6. Neuron Dendrites: (dend = tree) cell processes that carry electric impulses from an incoming nerve to a cell body. Hundreds per neuron. Nodes of Ranvier: (gaps between Schwann cells) Electrical signals jump from gap to gap, speeding conduction. Axon: Cell process that carries electric signals away from the cell body. Up to 3-4 ft. long. Schwann cells: made of fat, wrap around axon to form myelin insulation. Increases the speed of nerve conduction, like insulation. Cell body: Contains nucleus, cytoplasm, and organelles. Metabolic center of a cell.
