NURS 5315: Advanced Pathophysiology UTA Exam 1 LATEST UPDATED 2024 Atrophy Correct Answer: E. Cells decrease in size P. Still functional; imbalance between protein synthesis and degradation. Essentially there is an increase in the catabolism of intracellular organelles, reducing structural components of cell Physiologic: thymus gland in early childhood Pathological: disuse (muscle atrophy d/ decrease workload, pressure, use, blood supply, nutrition, hormonal stimulation, or nervous stimula...

NURS 5315: Advanced Pathophysiology Exam 1 Latest 2023. cells increase in number, mitosis (cell division) must occur, size of cell does not change Phys: increased rate of division, increase in tissue mass after damage or partial resection; may be compensatory, hormonal, or pathologic Patho: abnormal proliferation of normal cells usually caused by increased hormonal stimulation (endometrial). increase of production of local growth factors Ex: removal of part of the liver lead to hyperplasia...

How big is a typical human cell and can you see it with the naked eye? - ANSWER-10 um and no Why is a cell roughly 10 um? - ANSWER-This size allows the cell to effectively communicate with its environment through its plasma membrane. What would happen if a cell got bigger than 10um? - ANSWER-cell's membrane would not be able to efficiently communicate with its environment due to the increase in size. What are the 2 major classes of cells? - ANSWER-Solar cells & gametes. What is the lipi...
