Musculoskeletal System

What are the three types of muscle tissues in the human body?

• Skeletal, Cardiac, and Smooth

• Epithelial, Connective, and Nervous

• Skeletal, Cardiac, and Epithelial

• Smooth, Cardiac, and Connective

What is the primary function of skeletal muscles?

• To facilitate voluntary movement by attaching to bones.

• To support involuntary movement in the digestive system.

• To store energy in the form of fat.

• To produce hormones that regulate metabolism.

How do muscles work in pairs?

• Muscles work in antagonistic pairs, where one muscle contracts while the other relaxes to produce movement.

• Muscles work independently, contracting at the same time to produce movement.

• Muscles work in groups of three, with one muscle contracting and two relaxing.

• Muscles work in pairs, but both muscles contract simultaneously to produce movement.

What is homeostasis in the context of the muscular system?

• The ability of muscles to maintain stable internal conditions, such as temperature regulation through shivering and sweating.

• The process by which muscles contract to produce movement.

• The ability of muscles to grow in size and strength through exercise.

• The mechanism by which muscles store energy for future use.

What is the difference between voluntary and involuntary muscles?

• Voluntary muscles are under conscious control, while involuntary muscles operate without conscious control.

• Voluntary muscles are found only in the heart, while involuntary muscles are found in limbs.

• Voluntary muscles are always stronger than involuntary muscles.

• Involuntary muscles can be controlled consciously, while voluntary muscles cannot.

What is the effect of exercise on muscle tissue?

• Exercise has no effect on muscle tissue.

• Exercise can lead to muscle hypertrophy, increasing the size and strength of muscle fibers.

• Exercise decreases muscle mass over time.

• Exercise only improves cardiovascular health.

What type of muscle is responsible for the heartbeat?

• Skeletal muscle

• Smooth muscle

• Cardiac muscle

• Striated muscle

What is the role of smooth muscles in the body?

• To control voluntary movements in skeletal muscles.

• To control involuntary movements in organs such as the intestines and blood vessels.

• To provide structural support to the body.

• To facilitate the exchange of gases in the lungs.

What is the role of tendons in the muscular system?

• Tendons connect muscles to bones, allowing for movement when muscles contract.

• Tendons store energy for muscle contractions.

• Tendons protect muscles from injury during exercise.

• Tendons are responsible for the production of red blood cells.

How do skeletal muscles contribute to movement?

• They contract and pull on bones to create movement at joints.

• They provide structural support without movement.

• They store energy for future movements.

• They protect internal organs from injury.
