Skeletal muscles are made up of elastic muscle fibres that are bundled together and wrapped in connective tissue. Each skeletal muscle consists of different tissue types. These tissues include the skeletal muscle fibres, blood vessels, nerve fibres and connective tissue. Each tissue type has an important role and is vital in helping our bodies work the right way.
Muscles all work together by contracting and relaxing, which assists us in moving our body. Skeletal muscles also helps in stopping us from moving, like resisting against gravity and maintaining posture. Another important function is that they assist in preventing excess movement of our joints to maintain stability and preventing structural damage.
When a muscle is moved too far in one direction, or excessively loaded eccentrically (whilst being lengthened), the muscle fibres can break either partially or completely.
