Cardiac Muscle Research Paper

Cardiac muscle tissue consists of interlocking cardiac muscle cells or fibres which gives the tissue certain characterises. Each cardiac muscle cell consists of a single nucleus. These fibres are attached at their ends to adjoining fibres by thick plasma membrane called intercalated discs. Cardiac muscle makes up the wall of the heart. This type of muscle is responsible for contracting the heart in order to squeeze the blood out of the heart. The muscle can then relax to fill the heart up with blood. It is crucial that it is a strong muscle due to its importance within the body. This is achieved due to the branching and the striations throughout the cell. The branched sections are horizontal and the striations are vertical which creates a
