$\huge\mathbb\pink{Answer}$

→ Muscular tissues

Muscular tissues are soft tissues that make up the muscles. They are present in animals and have quality to contract and relax.

→ Features of muscular tissues -

• Contractllity
• Elasticity
• Extendibility
• Electrical excitability

→ Functions of Muscular tissues

• Producing body movements
• Stabilizing body positions
• Storing and moving substances in body.
• Generating heat.

→ Constituents of muscle fibre

★Muscle tissues are made up of myofibril.Myofibrils are the contractile units that make up each muscle fibre. Myofibrils can be looked upon as the building blocks of muscle and contain units called sarcomeres.
