Biceps brachii is responsible for arm flexion.

Neural muscle is not a type of muscle tissue; it's related to nerves.

Diaphragm muscle aids in breathing by contracting and relaxing.

Pulley is not a component of a lever; it's a separate mechanical device.

Quadriceps extend the knee joint.

The muscular system primarily produces movement.

Newton's second law of motion relates force, mass, and acceleration.

Trapezius muscle primarily stabilizes the shoulder.

A seesaw operates based on the lever principle.

Deltoid muscle primarily raises the arm.

Sarcomere is the smallest functional unit of a muscle.

Neuromuscular junction facilitates communication between nerves and muscles.

Actin forms thin filaments that, along with myosin, enable muscle contraction.

Tropomyosin regulates the availability of calcium ions, which is crucial for muscle contraction.
