Skeletons are made up of a system of bones in the body.
Axial skeleton
The axial skeleton is composed of 80 bones, including the skull, the ossicles, the hyoid bone, the rib cage, sternum, and vertebral column. The pelvis, upper & lower limbs and shoulder girdle make up the Appendicular skeleton.
Examples of bones in the axial skeleton include the skull, vertebral column, ribs, and sternum. These bones play a crucial role in protecting the central nervous system and supporting the body's structure.
The skeletal system includes the axial skeleton (Skull, Vertebrae, Sternum, Ribcage), and the appendicular skeleton (all else, including the arms, the legs, the pelvis, the shoulders, the fingers, and the toes.)
The axial skeleton is the central part of the skeleton, without the limbs. It's made up of the skull, spinal column, breastbone, and ribs. The rest of the bones make up the appendicular skeleton. Together, the axial and appendicular skeleton make up the human skeleton.

The axial skeleton is the part of the human skeleton that consists of bones of the head and trunk. It consists of 80 bones and is split into 8 different parts. Some are the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, the sternum, and the vertebral column.
Tarsals are NOT part of the axial skeleton. The axial skeleton includes the head and trunk. Tarsals would be part of the appendicular skeleton which consists of your appendages (arms and legs from the shoulder and hip joints out).
The skeleton you are referring to is the axial skeleton. It includes the skull, rib cage, and vertebral column (backbone), which provides structural support and protects vital organs such as the brain and heart.
The ribs, the thoracic vertebrae and the sternum, some would also consider the clavicle part of the thoracic cage.
This question doesn't really make sense... The clavicle is the collarbone. The sternum - usually people are referring to the manubrium when talking about the sternum - is the hard bone that looks like the body of a necktie protecting your heart in the front of the body. The ribs attach to the sternum in front, to the spine in back. The clavicle attaches to the sternum at the notch at the base of your neck. When you protract the shoulders (hunch them forward), the notch is more pronounced for ease of location. In fact, the sternoclavicular joint is the only skeletal attachment of the shoulder complex. So really, the clavicle doesn't join the sternum to anything. The clavicle is joined to the sternum, giving the shoulder girdle it's one attachment to the axial skeleton.
The term "endoskeleton" includes the others (skull, spine, and pelvis) because it refers to the internal framework of bones that provides support and protection to the body. The skull, spine, and pelvis are all examples of bones that make up the endoskeleton.
