Each segment of the sarcoplasmic reticulum forms a cufflike structure surrounding a myofibril, the fine contractile fibres that extend the length of striated muscle cells. something done by hand

"網頁Muscular tissue is a specialized tissue in animals which applies forces to different parts of the body by contraction. It is made up of thin and elongated cells called muscle fibers. It controls the movement of an organism. The cytoplasm in the muscle fibers is called sarcoplasm. It contains a network of membrane called the sarcoplasmic reticulum.
