As shown in Figure 12.3.5 below, skeletal muscle fibres are individually wrapped in connective tissue called endomysium. Cardiac muscle is found only in the wall of the heart. It is complex, having a physical and a cognitive component, and it is the result of many contributing factors. Components of connective tissue Types of Cells Weba. As shown in Figure 12.3.10, myocardium is enclosed within connective tissues, including the endocardium on the inside of the heart and pericardium on the outside of the heart. When attached between two movable objects, in other words, bones, contractions of the muscles cause the bones to move. As shown in Figure 12.3.6, a muscle fibre consists of a bundle of myofibrils, which are themselves bundles of protein filaments. Biomaterials.
