Types and components of joints gcse pe

What is the role of cartilage in the body?

• To produce blood cells.
• To provide a framework to support muscles and organs.
• To store minerals needed for vital body functions.
• To reduce friction between bones and act as a shock absorber to protect a joint.

What is the function of ligaments?

• Help to keep joints stable and prevent extreme movements.
• Produce blood cells.
• Store minerals needed for vital body functions.
• Provide a framework to support muscles and organs.

What do ligaments connect?

• Connect bone to cartilage.
• Connect bone to bone.
• Connect muscle to bone.
• Connect tendon to bone.

What types of movement occur at different joints?

• Flexion and extension at hinge joints, and abduction and adduction at ball and socket joints.
• Flexion and extension at ball and socket joints, and abduction and adduction at hinge joints.
• Flexion and extension at ball and socket joints, and rotation at hinge joints.
• Flexion and extension at hinge joints, and rotation at ball and socket joints.

Give an example of how tendons can support the movement of an athlete.

• The patellar tendon helps to stabilize the knee joint during running.
• The biceps tendon helps to flex the elbow joint during weightlifting.
• The rotator cuff tendons help to stabilize the shoulder joint during throwing.
• The Achilles tendon is crucial for a long jumper being able to push off from the floor; connecting the gastrocnemius muscles to the heel bone.

What types of joints are found in the body?

• Saddle joint and pivot joint.
• Hinge joint and pivot joint.
• Ball and socket joint and saddle joint.
• Hinge joint and ball and socket joint.

What is the function of tendons?

• Reduce friction between bones and act as a shock absorber.
• Help to keep joints stable and prevent extreme movements.
• Help to transfer the forces generated from muscular contractions to move bones into position.
• Provide a framework to support muscles and organs.

What are articulating bones?

• Bones that are connected by cartilage.
• Bones that move relative to each other at a joint.
• Bones that are connected by ligaments.
• Bones that are connected by tendons.

What do tendons connect?
