Question 1

What is the primary function of the skeletal system?

Accepted Answer

To protect vital organs and provide support.

Answer

The skeletal system provides the fundamental framework for the human body, offering structural support that allows for posture and movement. A primary function is to protect vital internal organs, such as the brain, heart, and lungs, from external damage. Additionally, bones store minerals and are responsible for producing blood cells.

Question 2

What is the role of ligaments in the musculoskeletal system?

Accepted Answer

To connect bones to bones and provide joint stability.

Answer

Ligaments are strong, fibrous bands of connective tissue that primarily connect bones to other bones, forming joints. Their crucial role is to provide stability to these joints, preventing excessive or unnatural movements that could lead to injury. They act as natural straps, holding the skeletal structure together while allowing for controlled motion.

Question 3

What does the term 'range of motion' (ROM) refer to?

Accepted Answer

The ability of joints to move through their full motion range.

Answer

Range of Motion (ROM) refers to the full extent of movement that a joint can achieve, from its maximum extension to its maximum flexion. It is a critical indicator of joint health and flexibility, representing the complete arc of motion possible without pain or restriction. Assessing ROM helps identify any limitations or hypermobility in a joint.

Question 4

What is the function of tendons in the body?

Accepted Answer

To connect muscles to bones and transmit force.

Answer

Tendons are tough, flexible cords of fibrous connective tissue that serve as the vital link between muscles and bones. When a muscle contracts, tendons transmit the force generated by the muscle to the bones, thereby causing movement at a joint. They are indispensable for all forms of physical activity and locomotion.

Question 5

What is the role of cartilage in joints?

Accepted Answer

To reduce friction and absorb shock in joints.

Answer

Cartilage is a smooth, elastic connective tissue found at the ends of bones within joints. Its primary functions are to reduce friction between bones, allowing them to glide smoothly over each other during movement, and to act as a shock absorber. This cushioning effect protects the joint from impact and wear, preventing bone-on-bone rubbing.
