MICROANATOMY

Detailed explanation-1: -Muscles cells contain a large number of mitochondria because muscle tissues require a large amount of energy for movement and especially during exercise. Since ATP is produced by mitochondria, muscles cells have a large number of mitochondria to fulfill the energy requirements.

Detailed explanation-2: -In the peripheral regions of the muscle cell, pools of globular mitochondria were found clustered together in the intracellular space between the sarcolemma and myofibrils (Romanul, 1964, 1965; Bubenzer, 1966; Gauthier and Padykula, 1966; Hoppeler et al., 1973a; Figure 1).
