NURS6501 Pathophysiology chapter 1
Latest Update Questions with Correct
Answers
actin filaments (microfilaments) - Answer -protein fibers that play a role in movement of cell and
organelles
action potential - Answer -a neural impulse; a brief electrical charge that travels down an axon. A
rapid change in the RMP
Active transport of Na+ and K+ - Answer -found in all cells. the pump moves sodium out and
potassium in. uses ATPase
ATP - Answer -(adenosine triphosphate) main energy source that cells use for most of their work
autocrine signaling - Answer -cells respond to signaling substances that they themselves secrete
Autophagy - Answer -A process in which lysosomes decompose damaged organelles to reuse their
organic monomers
basement membrane - Answer -Layer between epithelium and underlying connective tissue
cell adhesion molecules (CAMs) - Answer -proteins found on the surface of most cells that aid in
the binding of the cell to the extracellular matrix or other cells; integral membrane proteins; three major
families: cadherins, integrins, selectins
cell cycle - Answer -The regular sequence of growth and division that cells undergo
cell junctions - Answer -connections between cells that hold the cells together as a unit
cell signals - Answer -autocrine- from cell to it's own, paracrine- from cell to target cells nearby,
endocrine- from cell to far away cells (hormones or cytokines).
cell-cell adhesion - Answer -holds tissues together. forms organs
cellular communication - Answer -Cells in a large organism communicate by means of chemical
signals that are passed from one cell to another. communicate to maintain homeostasis, regulate growth
and division, and organization into tissues.
cellular functions - Answer -movement, conductivity, metabolic absorption, secretion, excretion,
respiration, reproduction, communication
cellular metabolism - Answer -anabolism is the use of energy, catabolism is the release of energy.
