  6. Mandible • The mandible is the jawbone and one of the strongest and the largest bones of the facial skeletal system. You are born with a mandible which is divided into two separate halves. As you grow, the median plane of symphysis of fibrous tissue help joining the mandible into one.

  8. Vertebrae • The vertebrae consists of the various bones of the spinal cord,. The vertebrae includes the cervical vertebrae of the neck, the thoracic vertebrae that is the point of attachment for ribs. It also consists of the lumbar vertebrae that includes the vertebrae of the lower back, the sacrum, that is, the five fused vertebral bones that are joined to the pelvis. The end point of the vertebrae column is the coccyx. It consists of four fused vertebrae that makes the tail bone.

  12. Ribs • The twelve pairs of ribs form a cage like structure, It helps in protecting the chest cavity and the major organs like lungs and heart

  13. Ribs

  14. Sternum • The sternum or breast bone is divided into three parts. The manubrium, body of sternum and xiphoid process. Of the twelve pairs of ribs, the first seven pairs are connected to the sternum through the costal cartilages.

  16. Clavicle • The clavicle or the collarbone runs horizontally from the base of the neck to the shoulder. The main function of the clavicle is to support the shoulder and provide mobility to the arm. It also helps in partly transferring the weight to the shoulder.

  21. Scapula • The scapula or shoulder blade is a large flattened, triangular-shaped bone. It is located in the posterolateral part of the thorax. The shoulder bone is thin, fragile and can be easily broken. Not common in sports.

  24. Humerus • The longest and the bone of the arm. It is a cylindrical shaft-like bone that has a flattened distal end and a rounded articular surface on the proximal end.

  25. Humerus

  26. Ulna • The ulna is the median bone in the forearm that runs parallel to the radius. On the proximal end, it has a hook-like articular surface. The distill end consists of a rounded head and a styloid process.

  30. Radius • The radius along with ulna makes up the bones of the forearm. These bones articulate with the humerus at the proximal end and the wrist bones at the distal end. The radius is the lateral bone of the forearm.
