Muscles Quiz

What are the three types of muscles?

• bicep, tricep, quadricep

• flexor, extensor, abductor

• skeletal, smooth, and cardiac

• upper, middle, lower

What is the main function of skeletal muscles?

• Enable movement and maintain posture

• Regulate body temperature

• Produce hormones

• Digest food and absorb nutrients

Which part of the muscle is responsible for muscle contraction?

• Mitochondria and ribosomes

• Nucleus and cytoplasm

• Endoplasmic reticulum and Golgi apparatus

• Myosin and actin filaments

What is the process of muscle contraction called?

• Mitosis

• Glycolysis

• Photosynthesis

• Myogenesis

What are some common muscle injuries?

• bruises, cuts, punctures

• strains, sprains, tears

• fractures, dislocations, contusions

• concussions, lacerations, dislocations

Which type of muscle is voluntary and under conscious control?

• Cardiac muscle

• Smooth muscle

• Involuntary muscle

• Skeletal muscle

What is the function of smooth muscles?

• Digesting food

• Involuntary movements in the body

• Regulating heart rate

• Voluntary movements in the body

What is the structure of cardiac muscles?

• Smooth and cylindrical with no intercalated discs

• Striated and branched with intercalated discs

• Non-striated and tubular with intercalated discs

• Striated and straight with no intercalated discs

What is the role of tendons in muscle movement?

• Tendons connect muscles to bones and transmit the force generated by the muscles to move the bones.

• Tendons help in storing excess water in the muscles

• Tendons are responsible for producing heat in the muscles

• Tendons are used for balancing the body during muscle movement

What is the sliding filament theory in muscle contraction?

• The sliding filament theory describes the process of muscle contraction by the sliding of actin and myosin filaments over each other.

• The sliding filament theory is the process of muscle relaxation by the separation of actin and myosin filaments

• The sliding filament theory is the process of muscle expansion by the stretching of actin and myosin filaments

• The sliding filament theory is the process of muscle growth by the fusion of actin and myosin filaments
