The skeletal system is made up of cartilage and bone. Both bone and cartilage are connective tissues, that is, they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells, the gelatin the support material for matrix, and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances, we can produce a material that is very hard like bone and can withstand weight or softer like cartilage which can be used as a cushioning material.

Some examples include the following: clavicle, coccyx, femur, fibula, foramen magnum, mandible, maxilla, metatarsals, ossify, phalanges, radius, scapula, sternum, suture, tibia, ulna, and vertebra. All of these terms are associated with the skeletal system. The mandible, maxilla, and foramen magnum are located in the cervical vertebrae. The clavicle, scapula, and sternum are located in the thoracic vertebrae. The lumbar vertebra contains the humerus, ulna, and radius. The coccyx is located in the sacral vertebrae. The femur, fibula, metatarsals, phalanges, and tibia are located in the appendicular skeleton. The sutures are located in the skull. The vertebrae is the backbone of the body. Ossification is the formation of bone. These terms are important in knowing and learning the skeletal system.

It consists of the shoulder gridle, the arm and hand, the pelvic girdle, the legs and feet. The parts in red in the image are where the appendicular bones can be found in the body. There are two hundred and six bones in the skeletal system. The five main types of bones are; Long bones, short bones, irregular bones,

Exploring the Skeletal System The precise number of bones in the adult human skeleton varies from one person to another, but on average there are 206 bones varying shapes and sizes. The skeleton is divided into two main parts. The central bones of the skull, ribs, spin (vertebral column) and breast bone (sternum) form the axial skeleton. The bones of the arms and legs, along with the shoulder blade (scapula), collar bone (clavicle) and pelvis make up the appendicular skeleton.

Bones are living tissues. They provide support, protect organs, contain multiple minerals, and store the marrow that creates cells for our entire body. Bones consist of compact bone, cancellous bone, osteoblasts, osteocytes, osteoclasts, osteoid, and inorganic salts. Compact bone is a dense bone tissue that makes up eighty percent of the human skeleton. It is made of primarily of inorganic salts, which produce bone hardness, and contains tiny spaces for osteocytes. Matured compact bone is layered, it contains vascular canals that provide necessary blood supply for osteocytes. Cancellous bone makes up the remaining twenty percent of the human skeleton. It is lightweight and porous, allowing small spaces for bone marrow and blood vessels.

The skeleton is a very important part of the body and is separated into two sections: the appendicular and axial skeleton. The appendicular is any part of the body that attaches to another bone. Those include but not limited to the legs, arms, and hands. The axial bones are located within the center of the body like the spine and ribs. Bones in these two regions are classified into different shapes including long, short, irregular, and flat. Flat bones are found in the skull and ribs. The flat bones in the human body are flat and thin often curved. Short bones are the same size length wise and width wise. Those are found in the wrist and ankle. Irregular bone does not go into a category. This bone can be found in the pelvis. Lastly, is the

The musculoskeletal system are made up of bones, joints, ligaments and muscles. The skeleton shapes up the body, protects the internal organs, is responsible for blood cell formation, and provides sites for muscle attachment. The muscles holds the skeleton straight and creates physical movement of the body. The skeletal system consists of bones formed from bone tissue that provide structure and function to the overall body. Also included in the skeletal system is the cartilage that forms the joints between bones and the ligaments that hold bones together at the joints. Bones can be split into long bones (arms, legs, hands, and feet), short bones (wrist, ankles, and knee caps), flat bones (ribs, sternum, shoulder blades, hip bones, and cranial

Muscles are attached to bones by tendons at their origin and insertion. Skeletal muscles produce movements by pulling on bones; bones serve as levers and joints act as fulcrums for the levers – an example of this is within the movement of the forearm: the elbow acts as the fulcrum which when bent, allows the movement of the ulna and radius bones because the bicep contracts. This is thoroughly explained below:

The musculoskeletal system is a made up of the muscular system and the skeletal system. The skeletal system provides the internal framework for the body, it protects the organs by enclosing it and anchors skeletal muscles so that the muscles can contract thus causing movement. The skeleton is divided into two divisions: the axial skeleton and the appendicular skeleton (Taylor & Cohen, 2013, p. 94). The Axial skeleton are the bones that have formed the longitudinal axis of the body which is made up of the skull, the vertebral column and the thoracic cage (Taylor & Cohen, 2013, p. 98). The Appendicular skeleton are the bones of limbs and griddles that are attached to the axial skeleton (Taylor & Cohen, 2013, p. 103).

The skeletal system includes the osseous tissues of the body and the connective tissues that stabilize or interconnect the individual bones. The bone is a dynamic tissue. Throughout the lifespan, bone adjusts to the physiologic and mechanical demands placed on it by the processes of growth and remodeling.

Have you ever thought about how humans would be without bones? They would not be able to function the way that they do now if it did not have bones. The skeletal system is a highly important system in the human body, it functions as support, protection, and creation of red blood cells. This system is composed of bones and joints, an average adult contains 206 bone and an average child contains 270 bones because as a person grows the bones fuse together to create a single bone. The skeletal system is divided in to two major category: the axial skeleton and the appendicular skeleton. The axial skeleton has 80 bones in the midline axis which contains the bones of the head and the trunk; while the appendicular axis has 126 bones which include the bones from the limbs, pectoral and pelvic regions. There are only a few select bones that are mainly affected by the Paget disease these include the pelvis and the tibia which belong to the appendicular axis; however, other bones that could be affected are the femur, spine, skull, clavicle, and fibula.

Long bones are strong bones and they are longer in length than they are wide, they must be able to withstand the force created when the body moves, each bone has a tubular shaft with a central cavity and two rounded

​The skeletal incorporates all of the bones and joints in the entire body. According to Inner Body, each bone is a complicated living organ that is made up of countless cells, protein fibers, and minerals (Taylor, undated). As the skeleton
