Short Answer

1. Draw a simple diagram of a neuron and label its components. In what ways are
neurons specialized for communication? How do these specialized features distinguish
neurons from other types of cells?
Answer: Neurons have axons and dendrites, structures for maintaining and transmitting
electrical potential, and synapses, all of which allow neurons to establish connections and
share information.

2. Glia are at least as numerous as neurons in the brain, yet neurons are the
predominant focus of neuroscience textbooks. Why?
Answer: Neurons generate and conduct electrical and chemical signals, while glia
primarily play a supporting role.

3. What was the substance of the disagreement between Golgi and Cajal that,
nevertheless, earned them both the 1906 Nobel Prize in Medicine or Physiology?
Answer: Golgi was a proponent of the “reticular theory,” which stated that all nerve
cells are connected, whereas Cajal argued that nerve cells are discrete entities, which is
now known as the neuron doctrine.
