Biomechanics Of The Elbow Quiz!

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.

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.

Women have much more fat padding on the inside part of the elbow than men, something that may protect them against certain types of injuries.

They’re micro-tears in the tendons, which attach the muscle to the joint. Your tendons still work, but you’ll feel some pain on the outside of your elbow. Treatment usually involves medication, rest, and physical therapy.

humeroulnar extension-olecranon of the ulna meets the floor of the olecranon fossa, when clinician is examining he should feel a bony end feel not a capsular one.

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.

Any repetitive use of your forearm muscle can cause it. And yes, tennis players can get it, too. Carpenters, auto workers, cooks, and butchers also get the condition more than other people.

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.

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.

The ulnar nerve runs down the inside of your elbow and controls hand movements and feeling in some fingers. You get that funny-bone feeling, like a mild electric shock, when it bumps against the bone that runs from your elbow to your shoulder -- the humerus. (Though it may not seem humorous when it happens.)
