A 7-year old child is bitten on the leg by a rabid fox. The virus replicates itself in the muscle at the site of the bite.

Neurons can be classified according to: (a) the number of neurites; (b) the presence or absence of dendritic spines; (c) connections and axon length. Based on these classifications, answer the following questions about cortical pyramidal neurons.

Based on its number of neurites a cortical pyramidal cell is a ____________________
Neuron.
Dendritic spines are ___________________ in cortical pyramidal neurons.
Cortical pyramidal cells have long axons that connect different areas of the brain so they are _________________________ neurons.
