MUSCLE PHYSIOLOGY

Detailed explanation-1: -A characteristic feature of the muscle fibre is the presence of large number of parallely arranged filaments in the sarcoplasm called microfilaments and myofibrills.

Detailed explanation-2: -A characteristic feature of the muscle fibre is the presence of large number of parallelly arranged filaments in the sarcoplasm called. No worries!

Detailed explanation-3: -The characteristic feature of the muscle fibre(muscle cell) is the presence of a large number of parallelly arranged filaments in the sarcoplasm called myofilaments or myofibrils.

Detailed explanation-4: -Within each muscle fiber are myofibrils-long cylindrical structures that lie parallel to the muscle fiber. Myofibrils run the entire length of the muscle fiber, and because they are only approximately 1.2 µm in diameter, hundreds to thousands can be found inside one muscle fiber.
