BIO11 Body Systems- Musculoskeletal System

Which of the following is a function of the bones in the musculoskeletal system?

• Producing red and white blood cells

• Providing attachment sites for muscles

• Storing excess glucose for energy

• Secreting hormones to regulate blood calcium levels

Answer explanation

Bones provide the framework for the body and serve as attachment sites for muscles. They also protect internal organs and produce red and white blood cells in the bone marrow.

Which of the following is a type of muscle in the musculoskeletal system that is responsible for involuntary movements?

• Smooth muscle

• Cardiac muscle

• Skeletal muscle

• Striated muscle

Answer explanation

Smooth muscle is a type of muscle in the musculoskeletal system that is responsible for involuntary movements such as the movement of food through the digestive tract, blood flow through blood vessels, and the constriction and dilation of airways.

Which of the following connects muscles to bones in the musculoskeletal system?

• Tendons

• Ligaments

• Cartilage

• Joints

Answer explanation

Tendons are tough, fibrous connective tissues that connect muscles to bones in the musculoskeletal system. They transmit the force of muscle contraction to the bone, allowing for movement.

Which of the following connects bones to other bones in the musculoskeletal system?

• Tendons

• Ligaments

• Cartilage

• Joints

Answer explanation

Ligaments are strong, fibrous connective tissues that connect bones to other bones in the musculoskeletal system. They provide stability to joints and help to prevent excessive movement or dislocation.

Which of the following is a tough, flexible connective tissue found in the musculoskeletal system that cushions joints and helps with movement?

• Tendons

• Ligaments

• Cartilage

• Joints

Answer explanation

Cartilage is a tough, flexible connective tissue found in the musculoskeletal system that cushions joints and helps with movement. It also serves as a shock absorber, reducing the impact of movements on the bones and joints.

Which of the following is a function of synovial fluid in the musculoskeletal system?

• Provides oxygen and nutrients to the bones

• Connects muscles to bones

• Helps cushion and lubricate joints

• Contracts to produce movement

Answer explanation

Synovial fluid is a thick, clear fluid that is found in joints and helps to cushion and lubricate them. It helps to reduce friction between the bones and allows for smooth movement.

Bones are a type of ___________ tissue that provide support and protection for the body.

___________ are responsible for producing movement in the musculoskeletal system.

Tendons are tough, fibrous connective tissues that connect ___________ to bones.

Ligaments are strong, fibrous connective tissues that connect ___________ to other bones.
