Why do cartage and ligaments heal so slowly?

Answer 1

Because it is sensative cartilage in your ear, and its one of those weak spots

Answer 2

Because tendons and ligaments (unlike muscle tissue) are virtually avascular meaning they have no blood supply and/or vessels to transport new nutrients and 'building blocks' like protein to rebuild and repair damage.

Answer 3

because it is a thicker tissue rather then the thinner layers of skin. this is why when people get cartilage piercings it take a few more weeks to heal than a normal ear lobe piercing. Also the cartilage is tougher therefore more force would have have to be used to inflict damage and with that could cause even more issues. Hope this gave you some info.

Answer 4

In order for any tissue in your body to heal, an adequate supply of blood is required. Bones, believe it or not, have a series of cavities running through them; the haversian and the perforating (volksmann) canals. These 'canals' have blood vessels running through them, supplying the compact bone with sufficient nutrients. So when you break a bone, it has an ample supply of required nutrients (namely calcium salts) to repair the fracture. Tendons, however, are avascular. This means that they do not have a direct supply of blood to them. Much like the epidermis of the skin which relies on the papillary layer of the dermis for nutrients, tendons rely on the diffusion of blood from capillaries in close proximity to gain the required nutrients to make the repair to the tissue, resulting in a lengthy healing time. Hope this helped!

Answer 5

they dont have a blood supply like other tissues in the body do

Answer 6

Because it is sensative cartilage in your ear, and its one of those weak spots

Answer 7

Becasue it's an avascular tissue.
