NSG 5003 Advanced Pathophysiology (South University)correctly answered to pass

NSG 5003 Advanced Pathophysiology (South University)Differentiation - correct answer (maturation) process in which cells become specialized in structure and function The eight specialized cellular functions are - correct answer movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction, communication Eukaryotic cells - correct answer Contain a nucleus and other organelles that are bound by membranes. The eukaryotic cell consists of three general components - correct answer plasma membrane, cytoplasm, and intracellular organelles Nucleus - correct answer A part of the cell containing DNA and RNA and responsible for growth and reproduction Vaults - correct answer cytoplasmic organelles that are carrying messengers of ribonucleic acid (mRNA) from the nucleus to the ribosomal sites of protein synthesis plasma membrane (cell membrane) - correct answer It's function is to protect the cell and control what goes in and out. It is not a solid structure. It is made of millions of smaller molecules so it is flexible and porous (allows things to pass through it). cellular receptors - correct answer protein molecules on the plasma membrane, in the cytoplasm, or in the nucleus that can recognize and bind with specific smaller molecules called ligands Ligands - correct answer A molecule that binds specifically to a receptor site of another molecule. Cells are held together by three different means: - correct answer (1) the extracellular membrane, (2) cell adhesion molecules in the cell's plasma membrane, and (3) specialized cell junctions. Cells communicate in three main ways - correct answer (1) they form protein channels (gap junctions); (2)
