TEST BANK PATHOPHYSIOLOGY THE BIOLOGICAL BASIS FOR DISEASE IN ADULTS AND CHILDREN BY McCance Chapter 1: Cellular Biology MULTIPLE CHOICE 1. Which statement best describes the cellular function of metabolic absorption? a. Cells can produce proteins. c. Cells can take in and use nutrients. b. Cells can secrete digestive enzymes. d. Cells can synthesize fats. ANS: C In metabolic absorption, all cells take in and use nutrients and other substances from their surroundings. The remaini...

Why is myelin important in the nervous system? A. It allows signals to travel faster along axons because depolarization occurs only at myelinated locations. B. It allows signals to travel faster along axons because depolarization occurs only at nonmyelinated locations. C. It bundles the dendrites of adjacent neurons together. D. It increases capacitance across the cell membrane, which helps electrical signals to leave the axons. E. It traps neurotransmitters, increasing their concentratio...

Sensory receptors Answer -Receptors convert stimuli in the environment into generator potential on sensory neuron -Sensory Neurons can be part of receptor or synapse on the receptor - different types of receptors are particularly sensitive to different, specific stimuli receptors cont. Answer -they can be free nerve endings on sensory nerves - receptors are sensitive to tissue damage and initiate sensation of pain via graded membrane potential charge -they can be specialized, independent...

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...
