Biomechanics is the science of movement that deals with muscles, bones, tendons, and ligaments as well as help to understand the mechanical principles of bones and joints. It focuses on the mechanics of the movement. This quiz has been made to test your basic knowledge about the mechanism of Elbow and joints. So, let's try out the quiz. All the best!

Questions and Answers

1.

Dr Karim is examining his patient's elbow, when his Px's arm is in full extension, while the patient is relaxed he should

C. Sudden pullling forces on child's arm

Explanation
It can happen innocently, when you lift or swing a child by the hand. It’s a kind of dislocation of the elbow that kids get more than adults because of their more flexible joints. Your child may feel pain right away in the elbow, wrist, or shoulder, and it might be hard for him to use or bend his arm. A doctor usually can put it back into place by hand.

What tough tissue grows over a broken bone during the healing process?
- A.
  
  Collagen
- B.
  
  Trabecular Bone
- C.
  
  Concellous Bone
- D.
  
  Red Bone Marrow
- E.
  
  Yellow Bone Marrow
Correct Answer
A. Collagen

Explanation
During the healing process of a broken bone, collagen, a tough tissue, grows over the fracture site. Collagen is a protein that provides strength and support to various tissues in the body. In the case of bone healing, collagen forms a callus, which is a temporary bridge of new bone tissue that helps stabilize and protect the fracture. Over time, this callus is gradually replaced by new bone tissue, allowing the broken bone to heal and regain its strength.

Which of the following is an example of a ball and socket joint?
- A.
  
  Knee
- B.
  
  Shoulder

  Elbow
- D.
  
  Both a and b
- E.
  
  All of the above
Correct Answer
B. Shoulder

Explanation
The shoulder is an example of a ball and socket joint. This type of joint allows for a wide range of motion in multiple directions. The ball-shaped head of the upper arm bone fits into the cup-shaped socket of the shoulder blade, allowing for movements such as rotation, flexion, extension, abduction, and adduction. The knee and elbow, on the other hand, are hinge joints that allow for back-and-forth movements in one plane only, while the shoulder joint provides a greater range of motion.

What is the purpose of cartilage?
- A.
  
  To prevent bones from wearing out
- B.
  
  To provide a smooth, durable material for joints
- C.
  
  To allow bones to rub against each other
- D.
  
  All of the Above
Correct Answer
D. All of the Above

Explanation
Cartilage serves multiple purposes in the body. Firstly, it helps prevent bones from wearing out by acting as a cushion between them, reducing friction and absorbing shock. Secondly, it provides a smooth and durable material for joints, allowing for smooth movement and reducing the risk of damage. Lastly, cartilage allows bones to rub against each other without causing damage, facilitating smooth articulation. Therefore, the correct answer is "All of the Above" as all the mentioned purposes are fulfilled by cartilage.

What should you drink to make your bones stronger?
- A.
  
  Soda
- B.
  
  Coffee
- C.
  
  Sports Drinks
- D.
  
  Milk
- E.
  
  Energy Drinks
Correct Answer
D. Milk

Explanation
Milk is the correct answer because it is a rich source of calcium, which is essential for strong and healthy bones. Calcium helps in building and maintaining bone density, preventing osteoporosis and fractures. Milk also contains other important nutrients like vitamin D, phosphorus, and protein, which further contribute to bone health. Soda, coffee, sports drinks, and energy drinks do not provide the same level of calcium and may even have negative effects on bone health due to their high sugar or caffeine content.
