Specialized Cellular Functions - ANSWER-Movement, Conductivity, Metabolic
Absorption, Secretion, Excretion, Reproduction, Respiration, Communication
Tight Junctions - ANSWER-a specialized connection of two adjacent cells. barriers
Desmosomes - ANSWER-Anchoring junctions that prevent cells from being pulled
apart
Gap Junctions - ANSWER-provide cytoplasmic channels between adjacent cells
for communication
Atrophy - ANSWER-↓ in cell size
Hypertrophy - ANSWER-↑ in cell size
Hyperplasia - ANSWER-↑ in cell #
Dysplasia - ANSWER-Deranged cell growth
Metaplasia - ANSWER-One cell type replaced by another
Microtubules - ANSWER-cytoskeleton: maintain cell shape + form mitotic
spindles + track for intracellular transport
1
, Actin filaments - ANSWER-cytoskeleton: involved in cell movement and muscle
contraction
Intermediate filaments - ANSWER-cytoskeleton: mechanical strength and stability
Ligand - ANSWER-bind with cellular protein receptor to activate or inhibit the
receptors associated signaling or biochemical pathway
Hypoxia - ANSWER-Low O2. Most common cause of cellular injury.
