In essential hypertention changes seen in the heart are
Cardiac cell hyperplasia
Cardiac cell hypertrophy
Incresed in the mitochondrial number
Increase in size of mitochondria
Ans. is 'b' i.e., Cardiac cell hypertrophy Hypertrophy - It's increase in size of a tissue d/t increase size of individual cells.Hyperplasia - Increase in size of a tissue as a result of increased no. of component cells . It's the principle mechanism for increased size in tissue composed of labile & stable cells.Hypertrophy is seen in following tissues #Tissue - Cause of increased demandsSkeletal muscle hypertrophy - physical activity, weight lifting*Cardiac muscle hypertrophy - Increased pressure load (Hypertension)*Increased volume load *("Valve incompetence causing regurgitation of blood")Smooth muscle hypertrophy - obstructive lesions (Wall of intestine & urinary bladder)Renal hypertrophy - Unilateral disease of one kidneyRemoval of one kidneyHyperplasia* is seen in - Breast growth* (during pregnancy & lactation)Both hypertrophy and hyperplasia* is seen in - uterine growth during pregnancy*
