Is bone cartilage and tendons muscle tissue?

Answer 1

No. Cartilage falls in the category of connective tissue, which add support to the frame of the body, including support to muscle tissue. (This is true except the case of blood, which because of its matrix of cells, is also considered connective tissue.)

Answer 2

No they are distinctly different from muscle tissue

Cartilage is a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the bronchial tubes and the intervertebral discs. It is not as hard and rigid as bone but is stiffer and less flexible than muscle.Unlike other connective tissues, cartilage does not contain blood vessels.

A tendon (or sinew) is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments and fasciae as they are all made of collagen except that ligaments join one bone to another bone, and fasciae connect muscles to other muscles. Tendons and muscles work together.
