Explain the difference between a sprain and a strain, label a diagram of bone structure, and match joints to their types.

Here are the solutions to your questions:

QUESTION 1
Differentiate sprain from strain.

• Sprain: A sprain is an injury to a ligament, which is a tough band of fibrous tissue connecting two bones or cartilages or holding together a joint. Sprains often occur when a joint is forced beyond its normal range of motion, causing the ligaments to stretch or tear.
• Strain: A strain is an injury to a muscle or tendon. Tendons are fibrous cords of tissue that attach muscles to bones. Strains typically result from overstretching or overusing a muscle or tendon.

QUESTION 2
Label the bone structure below.

• A. Articular cartilage
• B. Spongy bone (or Cancellous bone)
• C. Compact bone (or Cortical bone)
• D. Joint capsule (or Fibrous capsule)

QUESTION 3
Match the joint in Column A with the type of joint it represents in Column B. Write the letters only.

• 1. Shoulder: C (Ball-and-socket)
• 2. Elbow: E (Hinge)
• 3. Ankle: B (Gliding)
• 4. Thumb: A (Saddle)
