These adaptations include Atrophy, Hypertrophy, Hyperplasia, Metaplasia, and Dysplasia. Atrophy refers to a decrease in cell size due to reduced demand or adverse environmental conditions, conserving energy and resources. Hypertrophy is the increase in cell size, often seen in muscle cells in response to increased workload, leading to enhanced functional capacity. Hyperplasia involves an increase in the number of cells in an organ or tissue, usually in response to a stimulus and often as a preparatory process for hypertrophy. Metaplasia is the change of one type of cell to another that can better endure the stress or environment, a reversible adaptation. Dysplasia, while not a true adaptive process, is an abnormal growth or development of cells, often considered precancerous, indicating an early step in a potential progression to cancer🌿 Atrophy: ________ Decrease in cell size Response to reduced demand or adverse conditions Conserves energy Hypertrophy: ____________ Increase in cell size Occurs in response to increased workload Enhances functional capacity Hyperplasia: ____________ Increase in cell numbers Response to a stimulus Preparatory for hypertrophy Metaplasia: ____________ Change in cell type Reversible adaptation to stress Dysplasia: __________ Abnormal development or growth of cells Considered precancerous Early step towards cancer progression #CellularAdaptations #Atrophy #Hypertrophy #Hyperplasia #Metaplasia #Dysplasia #MedicalStudents #MBBS #BoardExamPrep #Pathology #FutureDoctors #MedEd #fmge #fmgevideos #rapidrevisionfmge #fmgejan2023 #mbbslectures #nationalexitexam #nationalexittest #neetpg #usmlepreparation #usmlestep1 #fmge #usmle #drgbhanuprakash #medicalstudents #medicalstudent #medicalcollege #neetpg2023 #usmleprep #usmlevideos #usmlestep1videos #medicalstudents #neetpgvideos #cellularadaptations
