- Neurons and synapses
- Neurons
- Cajal showed neurons are
individual units, separated by a
gap called a synapse.

silver nitrate
to stain
neurons

of a
neuron to
be seen

making up a large
amount of the cell's
"skeleton"

- Dendrite
- Size and shape
- Interneurons -
short or no
axons
- Neurons with massive
dendrites often
integrate information
from many others
- Long axons - transmit
information over long
distances
- E.g. neurons
going from the
motor cortex to
the spinal cord
