CHAPTER 3 NEUROSCIENCE CHAPTER LEARNING OBJECTIVES 1. Understand the key methods that scientists use to learn about brain anatomy and functioning. • Neuroscientists examine autopsy tissue and patients with localized brain damage to learn about brain anatomy and brain function. • EEGs and neuroimaging, such as PET scans and fMRI, allow scientists to study brain function in the living brain. 2. Describe the two major types of cells in the nervous system and describe the prima...

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - ANSWER TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. - ANSWER During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glial cells (i.e., m...
