Exploring Muscles, Bones, and Joints

What is the primary function of muscles?

• To protect internal organs from damage.

• The primary function of muscles is to produce movement.

• To produce hormones for growth.

• To store energy for the body.

How do muscles help in movement?

• Muscles help in movement by expanding and pushing against bones.

• Muscles help in movement by contracting and pulling on bones.

• Muscles enable movement by storing energy for later use.

• Muscles assist in movement by creating friction between joints.

What are the main components of bone structure?

• Cartilage, ligaments, and tendons.

• Blood vessels, nerves, and skin.

• Cells, extracellular matrix, and minerals.

• Muscle fibers, adipose tissue, and cartilage.

What type of tissue connects muscles to bones?

• Muscle fibers

• Ligaments

• Cartilage

• Tendons

What is the role of cartilage in joints?

• Cartilage reduces friction and absorbs shock in joints.

• Cartilage connects muscles to bones.

• Cartilage strengthens bones against fractures.

• Cartilage produces synovial fluid in joints.

Name the three types of muscle tissue.

• Skeletal, Cardiac, Smooth

• Tendons, Ligaments, Cartilage

• Voluntary, Involuntary, Striated

• Epithelial, Connective, Nervous

What is the difference between voluntary and involuntary muscles?

• Voluntary muscles are always larger than involuntary muscles.

• Voluntary muscles are found only in the heart.

• Voluntary muscles are controlled consciously, while involuntary muscles function automatically.

• Involuntary muscles can be controlled at will.

What are the different types of joints in the human body?

• Static, Dynamic, Mobile

• Fibrous, Cartilaginous, Synovial

• Hinge, Ball-and-socket, Pivot

• Elastic, Rigid, Flexible

How does a hinge joint allow movement?

• A hinge joint connects two bones without allowing any movement.

• A hinge joint permits lateral movement and twisting.

• A hinge joint allows movement by enabling flexion and extension around a single axis.

• A hinge joint allows rotation in multiple directions.

What type of joint is found in the shoulder?

• Hinge joint

• Ball-and-socket joint

• Saddle joint

• Pivot joint
