Front

What is the primary function of the deltoid muscle?

Back

The deltoid muscle is primarily responsible for shoulder abduction, flexion, and extension.

Front

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

Back

The three types of muscle tissue are skeletal, cardiac, and smooth muscle.

Front

What is the role of smooth muscle in the body?

Back

Smooth muscle is responsible for involuntary movements in internal organs, such as digestion and blood circulation.

Front

How do muscles typically work in the body?

Back

Muscles typically work in pairs, with one muscle contracting while the other relaxes.

Front

What is the main characteristic of skeletal muscle?

Back

Skeletal muscle is striated and under voluntary control, allowing for conscious movement.

Front

Where is cardiac muscle found, and what is its primary function?

Back

Cardiac muscle is found only in the heart and is responsible for pumping blood throughout the body.

Front

What is the function of the latissimus dorsi muscle?

Back

The latissimus dorsi muscle is responsible for the extension, adduction, and internal rotation of the shoulder.

Front

What type of muscle is responsible for voluntary movements?

Back

Skeletal muscle is responsible for voluntary movements.

Front

What is the difference between involuntary and voluntary muscle control?

Back

Involuntary muscle control occurs without conscious thought (e.g., smooth and cardiac muscles), while voluntary muscle control requires conscious effort (e.g., skeletal muscles).

Front

What is the significance of muscle pairs in movement?

Back

Muscle pairs allow for coordinated movement; when one muscle contracts, the opposing muscle relaxes, enabling smooth motion.
