Striated muscle tissue, such as the tissue of the human biceps muscle, consists of long, fine fibres, each of which is in effect a bundle of finer myofibrils. Within each myofibril are filaments of the proteins myosin and actin; these filaments slide past one another as the muscle contracts and expands.

Answer 2

Option (B) fusiform pattern is the correct answer.

• A muscle that possesses a shape of a spindle, which is wider in the middle and narrowing towards both ends. An illustration of a fusiform muscle is the biceps brachii.
• Fusiform muscle fibres ride parallel to a muscle's long axis. In this case, fibre length is equivalent to muscle length, and a fibre's force production transmits promptly to the tendon. This interpretation promotes immediate muscle shortening.
• An individual skeletal muscle may be composed of hundreds, or even thousands, of muscle fibres, bundled together and draped in a connective tissue wrapping.

Hence, option B is the correct answer.
