Q:

Does cartilage grow back?

A:

Cartilage only repairs where it connects to vascular tissue, as it does not have blood vessels or nerves of its own. This means cartilage regeneration and repair occurs extremely slowly, often being replaced by fibrous scar tissue instead. Contemporary medicine is creating effective methods of cartilage repair.

Cartilage regeneration occurs with specialized cells called chondrocytes. Modern medicine can remove healthy chondrocytes, grow them in a laboratory setting and implant them in areas where cartilage damage has occurred, such as in the knees and shoulders of athletes. Additionally, a procedure can implant the meniscus, a cartilage cushion between the upper and lower leg bones at the knee, harvested from a cadaver.

    Do your ears and nose continue to grow?

    A:

    Cartilage, which makes up most of ears and noses, continues to grow even after other parts of the human body, even bone, stop growing, according to Arthur Perry, M.D., of the Dr. Oz Show, although other experts disagree. The force of gravity also works on earlobes to cause elongation.

    What causes bruising?

    A:

    Ruptures or tears of the small blood vessels known as capillaries result in bruising, according to WebMD. These ruptures allow blood to escape the circulatory system and enter other tissue. Most of the time, normal bruising heals on its own and is not reason for concern. During the two to four weeks a bruise requires for healing, it undergoes several color changes.
