Cell Growth and Cell Death Crossword Puzzle

QUESTIONS LIST:

• atrophy : the shrinkage of a tissue or organ due to a decrease in size and/or number of cells
• neuronalplasticity : process where new neuronal pathways are formed to allow regaining of function following tissue damage
• scar : the tissue formed when extensive tissue damage occurs, resulting in permanent damage and the formation of this tissue instead of regeneration of functional tissue
• metaplasia : the reversible change of one differentiated cell type to another
• hyperplasia : an increase in the tissue or organ size due to increased cell number, without an increase in cell size
• dysplasia : the formation of abnormally differentiated cells within a tissue, like that caused by human papillomavirus (hpv) in the cervix
• regeneration : the replacement of cell losses by identical cells to maintain tissue or organ size
• adaptations: changes made by cells in response to various stimuli or changes in their local environment.
• apoptosis : programmed cell death whereby a cell dies.
• hypertrophy : an increase in the tissue or organ size due to an increase in cell size, without an increase in cell number
• differentiation : cells take on specialised form and function
• stemcells : undifferentiated, unspecialised cells that are capable of self-renewal
• growthfactors : molecules that act on cell surface receptors, stimulating the transcription of genes that regulate the cell cycle, e.g, egfr, vegf and pdgf
