The human skeleton protects the inner organs, supports the body's frame, stores the body's chemicals and minerals, facilitates blood transportation and formation and makes movement possible. The skeleton is made up of more than 200 connected bones. Skeletons also contain cartilage, which are the thick, rubber-like tissues found in joints.Continue Reading
According to InnerBody, each bone in the human skeleton contains blood vessels and bone marrow made of fat cells, connective tissue cells and nerve cells that help transport blood throughout the body. The skeleton also helps to hold internal organs in place. For example, the human skull keeps the brain stationary, and the chest cavity supports the heart and lungs. The human skeleton not only encases vital organs, but it also protects them from damage.
Human bodies are able to move because skeletal bones contain ligaments and tendons, which perform certain movements when specific muscles contract. The shape and size of each bone affects its potential range of motion. For example, the small bones in a person's hands make it possible to perform precise, detailed activities, such as writing or tying shoelaces. The large bones that make up the legs and arms allow humans to walk, run and lift objects.Learn more about Bones
Functions of the human spine include supporting the body's weight, facilitating movement and flexibility and protecting other structures in the vulnerable spinal cord from injury, including the brain and inner organs. The spine consists of over 20 small bones, stacked vertically and connecting with other structures in the body, including nerves and muscles. The spine, in coordination with these other features, supports the life functions of organs and enables sensory perception, thought and locomotion.Full Answer >
The four primary functions of the skeletal system are to support muscles and tissue, protect the vital organs, allow movement of bones and muscles and serve as the storage center for immature blood cells and minerals. The skeletal system has 206 bones that are vital to the human body.Full Answer >
An interesting fact about the human skeleton is that the number of bones varies by age. Babies have close to 300 bones, while most adults have 206. The "extra" bones in the baby's body eventually fuse together to form larger bones.Full Answer >
The function of the scapula is to provide movement and stabilization of the arm at the shoulder by attaching it to the trunk of the body, known as the thorax. The scapula is a flat bone that is shaped somewhat like a triangle. The scapula, along with the clavicle and humerus, make up the shoulder.Full Answer >
