What do the skeletal system consists of ?
- Cartliage- a connective tissue is the enviroment in which bone develops in a fetus. Also formed at end of certain bones and joints in adults. Provides smooth surface for bones to move aganist each other. - Liagments- are tough connective tissue structures that attach bones to bones like the ligament that attach the head of the femur to the acetubulum of the pelvic bone in the hip joint. - Tendons- are similar structure that attach muscle to bone.
