Questions and Answers

Match the type of joint with its characteristic movement:

Condyloid Joints = Movement in two planes (flexion/extension, abduction/adduction) Pivot Joints = Movement in multiple planes (flexion/extension, abduction/adduction, rotation) Ball and Socket Joints = Rotation around a single axis Gliding Joints = Limited movement, usually in one plane

Match the type of joint with its example:

Condyloid Joints = Atlanto-axial joint (C1-C2) Pivot Joints = Wrist joint Ball and Socket Joints = Metacarpophalangeal joints Gliding Joints = Shoulder joint

Match the type of joint injury with its definition:

Sprains = Bones are forced out of their normal position Strains = Overstretching or tearing of ligaments Dislocations = Overstretching or tearing of muscles or tendons Tendinitis = Not mentioned in the notes

Match the type of joint with its bone structure:

Condyloid Joints = One bone rotates within a ring formed by another bone Pivot Joints = Two bones articulate with each other, allowing for movement in two planes Ball and Socket Joints = One bone has a rounded head that fits into a cup-like depression in another bone Gliding Joints = Two flat bone surfaces slide past each other Signup and view all the answers

Match the cause of joint injuries with its description:

Overuse or repetitive stress = Sudden, forceful movements Sudden, forceful movements = Poor technique or biomechanics Poor technique or biomechanics = Overuse or repetitive stress Insufficient warm-up or cool-down = Not mentioned in the notes Signup and view all the answers

Match the type of joint with its movement limitation:

Condyloid Joints = Movement is limited to rotation around a single axis Pivot Joints = Limited movement, usually in one plane Ball and Socket Joints = Movement occurs in multiple planes Gliding Joints = Movement in two planes (flexion/extension, abduction/adduction) Signup and view all the answers
