After his graduation from the Normal School, Washington went on to establish a school at Tuskeegee, Alabama the flowering of this school would be his lifes work and one of his greatest achievements. Skeletal muscle cells appear striated due to regular arrangements of two types of protein filaments in sarcomeres. The outermost connective tissue sheath surrounding the entire muscle is known as epimysium. Muscle fatigue is due to low ATP and increased lactic acid. Muscle tissue is classified into three types according to structure and function: skeletal, cardiac, and smooth ( Table 4.2 ). The signal to contract is passed from one myocyte to the next through gap junctions. Thick and thin filaments assemble into cylindrical myofibrils with each thick filament surrounded by six thin filaments.
