The Skeletal System
The skeletal system is the basic framework around which your body is build. The skeletal system is a combination of all the bones in the body and tissues such as tendons, ligaments and cartilage that connect them all. It has obvious functions like movement, support, protection and so on. To put this into perspective, one must appreciate the knowledge that there are 206 bones and a few cartilages in an adult human body working together to perform all the above-mentioned functions.
These functions are discussed in further detail:
The primary job of the skeleton is to provide support for the human body. Without this skeletal system, our body would collapse into a pile of skin and guts on the floor. This skeleton is strong yet light.
The skeletal system also helps to protect your internal organs and fragile body tissues like the brain, heart, lungs and spinal cord by acting as a buffer. Our cranium (skull) protects our brain and eyes, the ribs protect our heart and lungs and our vertebrae (spine, backbones) protect our spinal cord.
Bones provide the basic structure for muscles to attach themselves onto so that our bodies are able to move. Tendons are tough inelastic bands that attach our muscle to that particular bone.
This skeletal system can be divided into the axial and appendicular systems. The axial comprises of the skull which has 22 bones fused together except for the mandible. These bones are separated in children, to allow for growth. Then comes the Hyoid or the floating bone and auditory ossicles which happen to be the smallest bones in the body. Sternum connects to the ribs by thin bands of cartilage and the vertebral column. While the appendicular skeleton consists of 126 bones in the following regions, the upper limbs, lower limbs, pelvic girdle and the pectoral (shoulder) girdle.
