Power point presentation Anatomy and physiology of muscle growth (PPT of muscle growth)
• Bundles of fibers surrounded by a thin layer of connective tissue: Sarcolemma.
• Hooked to the bony plates of the skeleton by strong tendons.
• Receiving stimuli from nerves originating from the anterior horns of the spinal cord.
• Each fiber being a multinucleated cell consists of myofibrils in bundles with a large number of mitochondria and a myoglobin (pigmented protein).
• Muscles represent 50% of the weight of the adult human 20% of that weight is Protein and remaining parts are salts and water.
• Autonomic nervous system control smooth and cardiac muscles.
• Central nervous system controls the voluntary muscles.
