This gives shape and helps with movement. The clavicle and scapula help to form the shoulder.The rib cage helps protect the heart and the lungs.The sternum helps to form the rib cage.The spinal cord runs in the center of the vertebrae.This is made up of vertebrae which are hollow and joined together. The backbone is called the vertebral column.The facial skulls help to protect the eyes.The skull, cranial and facial bones do not move except for the jaw bone.The skull has the cranium which is the strongest bone.The cartilage is mostly found between bones.The skeletal system is made up of bone and cartilage.Yellow bone marrow is found in long bones. The yellow bone marrow is used to store fat cells. The red bone marrow has the main function of making red blood cells. There are two different types of bone marrow, red bone marrow, and yellow bone marrow. These bones are used for movement and to frame the body in shape. The long bones are also made up of spongy bones and a compact bone. The growth plate allows people to continue to grow until the growth plate closes. The metathesis is also called the growth plate. The long, middle portion of the long bone is called the diathesis and the end of the long bone is called the epiphysis and the small area between the two is called the metathesis. Long bones are the humerus, the femur, and other bones. The flat bones have a spongy or cancellous bone which and the outer shell or the compact bone.įlat bones help to protect the organs and help to protect the bone marrow. These bones are called flat bones because they describe their shape. Flat bones are bones that make up the skull, the ribs, and the pelvis. The pelvis forms the appendicular skeleton which is attached to the axial skeleton. The axial skeleton includes the skull and the ribcage and the vertebra column. There are two parts of the skeleton, the axial skeleton, and the appendicular skeleton. White and red blood cells and platelets are found inside of the bone, and this is part of the bone marrow. The skeleton also helps to store calcium and hematopoiesis, which is how the blood produces cellular components such as proteins, plasma, and other cells such as white blood cells, red blood cells, and platelets. The skeleton helps to protect our organs such as our brain, heart and lungs, and other organs. The limbs and joints in our body help the bones to be able to move. Our body is supported by all of our bones that allow us to stand and to sit. Humans are vertebrates and being a vertebrate means that we have bones that are located on the inside of the body and this is called an endoskeleton. In the human skeleton, there are 206 bones. The skeletal system has the job to help protect the body and to help the body to move.
