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. Cell body: Contains nucleus, cytoplasm, and organelles. Metabolic center of a cell. Axon: Cell process that carries electric signals away from the cell body. Up to 3-4 ft. long.

Metabolic center of a cell. 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.
