To discuss:
Organs and tissues that constitute the skeletal system.
Introduction:
The human skeleton is composed of 206 bones and it provides for multifunctional structure which also includes joints, cartilages, tendons and ligaments connect to each other as a network. The skeletal system is the major support for the body, locomotion, protects the internal organs, and provide blood cell protection. It is divided to axial and appendicular skeleton. The axial skeleton is the central axis of the body consist of 80 bones with skull bone, middle ear called ossicles, throat bones called hyoid, vertebral and thoracic cage. It has the major function in protection and also supports the spinal cord. The appendicular skeleton consists of 126 bones, upper and lower limbs also with shoulder and pelvic bones.
