Skeletal System
The skeletal system is made up of 206 bones. It also includes cartilage, ligaments and tendons. The two main parts of the skeletal system are the axial skeleton with 80 bones and the appendicular skeleton with 126 bones. The primary purpose of the skeletal system is to provide the body with support, protection, movement, storage for minerals and lipids, and to produce red blood cells. The axial skeleton includes the skull, thoracic cage and vertebral column. The skull protects the brain, the thoracic cage protects the heart and lungs, and the vertebral column protects the spinal cord.
The appendicular skeleton includes the pectoral girdle, the upper limbs, the pelvic girdle, and the lower limbs. This allows for movement, protection and support of the internal organs.
The skeletal system provides the support for the entire body. Individual bones or groups of bones provide a framework for the attachment of soft tissues (muscle and organs).

This allows the bones in the body to move. Joints are a significant part of the movement of the body. The three major types of joints are immovable (synarthrosis), slightly movable (amphiarthrosis) and movable (diarthrosis). An example of a synarthrosis joint would be the joint between the bones of the skull. An example of an amphiarthrosis joint would be the joint area between the tibia and fibula. An example of a diarthrosis joint would be the elbow or

    Other spaces act as storage areas for red bone marrow. The regions of a bone may be categorised as spongy and compact depending on the size and distribution of the spaces. In general, around eighty per cent of the skeleton is compact bone and twenty per cent is spongy bone (Tortoar and Derrickson, 2009). There are two types of bone tissues; compact and spongy. Compact bone tissue is hard and dense; it provides strength, support and protection.…

    The Skeletal System is basically the skeleton that helps support your entire body. In the skeletal system, however, there is more than one form of skeleton: the external exoskeleton of arthropods and the internal endoskeleton of vertebrates. The skeleton itself has 206 bones in the adult human body. The skeleton has two forms: the axial skeleton and the appendicular skeleton. The axial skeleton supports the center axis of the body and consists of the skull, vertebral column, and the rib cage.…

    The brain and eyes are protected by the skull, while the heart and lungs are protected by the ribcage. The skeleton also provides a framework for the human body. Without bones, the body would not be able to maintain its shape. Instead, skin, organs and blood vessels would all be in a pile on the ground. Tendons attach the muscles to the bones, which allow humans to walk, jump, talk and perform hundreds of other…
