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...

Psychopharm Exam 1 practice 170 Questions with Verified Answers The PMHNP is evaluating a 68-year-old man for symptoms of major depression. While assessing the appearance of the patient, an obvious left-sided ptosis is noted. Which cranial nerve is directly linked to this condition? a. III b. IV c. V d. VI - CORRECT ANSWER A A 55-year-old woman has been referred for a psychiatric evaluation for a change in personality, lack of impulse control, and increasingly reckless decision-making....

NR546 Quiz reviews - Weekly Quiz review Propagation of an action potential to the axon terminal is mediated by voltage-sensitive sodium channels. Influx of sodium through voltage-sensitive sodium channels at the axon terminal leads to opening of voltage-sensitive calcium channels, also at the axon terminal. Influx of calcium through the open voltage sensitive calcium channels leads to docking of synaptic vesicles and secretion of neurotransmitter into the synapse.Agonists cause ligand-gate...

T or F: Potassium ions are at high concentrations inside of cells, including neurons - ANSWER-True The action potential is a result of: - ANSWER-the movement of ions The post-synaptic cell can be: - ANSWER-in glands, muscle cells and neurons Th resting potential of a neuron is - ANSWER--60mV T or F: The cell body refers to the part of the neurons that begin at the dendrites and extend to the axon terminal - ANSWER-false T or F: Voltage gated ion channels open when a protein binds ...

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...
