A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture . [ 1 ]
A strong electric shock can often cause painful muscle spasms severe enough to dislocate joints or even to break bones. The loss of muscle control is the reason that a person may be unable to release themselves from the electrical source; if this happens at a height as on a power line they can be thrown off.
Wrist mobility is often restricted due to inflammation of the forearm muscles as they contract and tighten due to injury. [2] Most wrist dislocations occur between the capitate and the lunate. [17] [18] Carpal fractures are caused by falling on an outstretched hand the wrist is hyper-extended in ulnar deviation with a component of rotation. [18]
"Listen to your body, rest, recover, and if it doesn't go away or you're in pain every time you try a certain activity, you need to be evaluated," says McDermott. Jump on a backyard trampoline
A direct hit to the collarbone can also cause a break. In most cases, the direct hit occurs from the joint side towards the body side of the bone. The muscles involved in clavicle fractures include the deltoid, trapezius, subclavius, sternocleidomastoid, and sternohyoid. The ligaments involved include the conoid ligament and trapezoid ligament.
Normally, bone continuously breaks down and rebuilds—old bone is resorbed and replaced with new bone. The process keeps the skeleton strong and helps it to maintain a balance of minerals. [23] In the course of avascular necrosis, however, the healing process is usually ineffective and the bone tissues break down faster than the body can ...
Humans have both light meat and dark meat due to type 1A and type 2B muscle fibers. However, humans are lean and not very calorie dense, so if you're already starving cannibalism doesn't do much good.
Muscle memory helps you get back into shape faster after a break, makes complex movements feel more intuitive, and allows you to transition between similar activities easier (think: from tennis to ...
