MULTIDIMENTIONAL CARE 1/NUR2356 - Fundementals Exam 1 2021/2022. Define cellular regulation? Cellular regulation is the genetic and physiologic processes that control cellular growth, replication, differentiation, and function to maintain homeostasis. Define Immunity? protects the body from foreign invaders and non-self-cells Define Mitosis? Mitosis makes one cell divide into two new cells that are identical to each other and to the cell that began mitosis. Define Neoplasia? Any new or continued cell growth not needed for normal development or replacement of dead and damaged tissues In relation to the biology of normal cells…. Define Specific morphology? Specific morphology is the feature in which each normal cell type has a distinct and recognizable appearance, size, and shape. Define a small nuclear-to-cytoplasmic ratio? means that the nucleus of a normal cell occupies a relatively small amount of space inside the cell. Define differentiated function? Means that every normal cell has at least one function it performs to contribute to whole-body function. For example, skin cells make keratin, liver cells make bile, cardiac muscle cells contract, and red blood cells make hemoglobin. Define Tight Adherence occurs because normal cells make sticky cell adhesion molecules (CAMs) that protrude from the membranes, allowing cells to bind closely and tightly together. Exceptions are blood cells that circulate freely as individual cells. Red blood cells and white blood cells produce no CAMs and do not usually adhere together
