Skeletal System Research Paper
For this assignment we are looking at the skeletal system. The skeleton is the internal framework of our body. It is made up of three things; bones, cartilage and joints. Without these three things we would just be a heap of skin, muscle and internal organs. The skeleton is made up of 206 bones that are separated into two groups. Firstly, the Axial Skeleton. The Axial skeleton is made up of 80 different bones whereas the Appendicular skeleton is made up of 126 bones.
The Axial Skeleton
The axial is a particular part of the skeleton that is made up of the bones in the head and trunk of a vertebrate. In a regular human body there are 80 different bones and is composed of several different parts; the Skull bones, the Ossicles of the ear, the …show more content…
The bones act as an anchor that muscles can pull in order to create movement. Where two bones meet, a joint is formed, allowing movement between the two bones.
Different types of bones
In the human body there are five different types of bone. Long Bones, Short Bones, Flat Bones, Irregular Bones and Sesamoid Bones.
Long Bones – Long Bones are hard, dense bones that provide strength, structure and mobility. An example of a long bone is the Femur (thigh bone). A long bone has a shaft and two ends. There are also bones in the fingers hat are classed as long bones that are in actual fact short in length. Short Bones – The short bones are small and many of them are found in the hands and feet. Their primary function is to provide support and stability with either little or no movement. An example of a short bone is a Carpus.
Flat Bones – Flat bones are bones whose principle function is either extensive protection or the provision of broad surfaces for muscular attachment. These bones are expanded into broad flat plates.
Irregular Bones – The irregular bones are bones that are shaped really differently to all of the other types of bone. For this reason they have to be put in their own …show more content…
People usually refer to the tibia as the shinbone, and is the second largest bone in the human body.
Tarsals – The tarsals are a set of seven irregularly shaped bones. They are situated in the foot and in the ankle area.
Metatarsals – The metatarsals are used to connect the phalanges to the tarsals. They are found in the foot.
Vertebral column – The vertebral column is more commonly known as the spinal column. It's mainly used for protection of the spinal cord. It also provides stiffening for the body and attachment for the pectoral and pelvic girdles.
Cervical – The cervical is the vertebrae of the neck. The first two are known as the Atlas and the Axis. They form a pivot joint that allows both the head and the neck to move with out any difficulties. The cervical can be damaged easily because it is the smallest vertebrae in the body.
Thoracic – Similar to the cervical, the thoracic is a vertebrae. It is the vertebrae in the middle of the spine which articulate with the ribs. They are positioned in the thorax ( A structure that protects the heart and
