The skeletal system consists of bone, ligaments, cartilages and other tissues.

Movement: It helps in movement and locomotion of the body.
Protection: It protects the internal organs of the body. For example, the skull protects the brain, vertebrate protects the spinal cord et cetera.
Blood cell production: Haematopoiesis mainly occurs in the bone marrow.
Storage: It can store minerals like iron and calcium.
Endocrine regulation: Osteocalcin released from bone cells contributes to the blood sugar (glucose) regulation and fat deposition.
