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
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
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)
Match the type of joint injury with its effect:
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 articulation:
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 = One bone has a rounded head that fits into a cup-like depression in another bone
Match the type of joint with its example location:
Condyloid Joints = Tarsal bones in the foot Pivot Joints = Metacarpophalangeal joints Ball and Socket Joints = Wrist joint Gliding Joints = Joints between carpal bones in the wrist
What is the primary energy source utilized by the Lactic Acid (LA) system to provide energy during high-intensity anaerobic activities?
Glucose
What is the duration of the LA system during high-intensity anaerobic activities if the exercise is performed at maximum intensity?
Up to 30 seconds
What is the main limitation of the LA system during anaerobic activities?
The onset of blood lactate accumulation (OBLA)
What is the percentage of potential energy freed by the LA system during anaerobic activities?
5%
What is the duration of the LA system during anaerobic activities if the intensity is lowered?
Up to a few minutes
What is the advantage of the LA system in terms of ATP resynthesis?
Resynthesizes two molecules of ATP
What is the characteristic of the LA system that makes it readily accessible?
Large glycogen store in muscle/liver
What type of sports activities primarily utilize the LA energy system?
High-intensity activities from 10-180 seconds

Joints in Physical Education
Types of Joints
Condyloid Joints
- Also known as ellipsoidal joints
- Two bones articulate with each other, allowing for movement in two planes (flexion/extension, abduction/adduction)
- Examples: wrist joint, metacarpophalangeal joints
Pivot Joints
- One bone rotates within a ring formed by another bone
- Movement is limited to rotation around a single axis
- Examples: atlanto-axial joint (C1-C2), proximal radioulnar joint
Ball and Socket Joints
- One bone has a rounded head that fits into a cup-like depression in another bone
- Movement occurs in multiple planes (flexion/extension, abduction/adduction, rotation)
- Examples: shoulder joint, hip joint
Joint Injuries
- Common types of joint injuries:
- Sprains: overstretching or tearing of ligaments
- Strains: overstretching or tearing of muscles or tendons
- Dislocations: bones are forced out of their normal position
- Causes of joint injuries:
- Overuse or repetitive stress
- Sudden, forceful movements
- Poor technique or biomechanics
- Insufficient warm-up or cool-down
Gliding Joints
- Two flat bone surfaces slide past each other
- Limited movement, usually in one plane
- Examples: joints between tarsal bones in the foot, joints between carpal bones in the wrist
Note: These notes provide an overview of the different types of joints, their characteristics, and examples of each. Additionally, they touch on joint injuries, including common types and causes, and briefly cover gliding joints.
