Perimysium
Endomysium
Epimysium
Sarcolemma
Answer explanation
The outermost membrane covering the entire muscle is called the epimysium. It encases the muscle belly, while the perimysium surrounds bundles of muscle fibers, and the endomysium covers individual fibers.

Which proteins are found in the myofilaments necessary for muscle contraction?
Actin and tropomyosin
Myosin and troponin
Actin and myosin
Tropomyosin and sarcolemma
Answer explanation
The proteins necessary for muscle contraction are actin and myosin. Actin forms thin filaments, while myosin forms thick filaments. Together, they interact to produce muscle contraction through the sliding filament mechanism.

What is the function of the sarcoplasmic reticulum in muscle fibres?
It is the muscle's cell membrane.
It stores calcium for release on demand.
It separates muscle fibers.
It contains contractile proteins.
Answer explanation
The sarcoplasmic reticulum is crucial in muscle fibers as it stores calcium ions. Upon stimulation, it releases calcium, which is essential for muscle contraction, making 'It stores calcium for release on demand' the correct choice.

What are the smallest units of muscle contraction called?
Myofibrils
Sarcomeres
Fasciculi
Tendons
Answer explanation
The smallest units of muscle contraction are called sarcomeres. They are the repeating units within myofibrils that contract to produce muscle movement.

What is the role of tendons in the muscular system?
They store calcium.
They attach muscle to bone.
They separate muscle fibers.
They contain contractile proteins.
Answer explanation
Tendons play a crucial role in the muscular system by attaching muscles to bones, allowing for movement when muscles contract. This connection is essential for the skeletal system to function effectively.

What is the connective tissue that covers each muscle called?
Perimysium
Endomysium
Epimysium
Sarcoplasmic reticulum
Answer explanation
The connective tissue that covers each muscle is called the epimysium. It encases the entire muscle, providing support and protection, while the perimysium and endomysium cover bundles and individual muscle fibers, respectively.

What are muscle fibres made up of?
Sarcomeres
Myofibrils
Myosin heads
Actin filaments
Answer explanation
Muscle fibres are primarily made up of myofibrils, which are long, thread-like structures containing the contractile units called sarcomeres. Myosin heads and actin filaments are components within sarcomeres, not the fibres themselves.
