Answer 2

During compression, the slight fibres slide past the thick fibres, shortening the sarcomere.

Muscle activity

• During compression, the slight fibres slide past the thick fibres, shortening the sarcomere. The good and bad fibres accomplish the real work of a muscle, and the manner in which they do this is cool. Thick fibres are made of a protein called myosin.
• At the sub-atomic level, a thick fibre is a shaft of myosin particles organized in a chamber. Meagre fibres are made of another protein called actin. The slight fibres seem to be two strands of pearls curved around one another.
• During relaxation, the myosin thick fibres take hold of the actin slight fibres by shaping cross bridges. The thick fibres pull the slender fibres past them, making the sarcomere more limited. In a muscle fibre, the sign for withdrawal is synchronized over the whole fibre so each of the myofibrils that make up the sarcomere abbreviates at the same time.
