Um...bone?
The substance that makes up the skeleton is called "calcium phosphate," which combines with other minerals and proteins to form bone tissue. Additionally, bone tissue is constantly being broken down and rebuilt in a process called remodeling.
Ligaments are connective tissues that connect bones to bones.
The appendicular skeleton is primarily made up of bone tissue (osseous tissue). This includes bones of the limbs (arms and legs), shoulder girdle, and pelvis. These bones provide structure, support, and attachment points for muscles.
its called the spongy bone
The bone marrow
Muscle tissue.

Osteoblast makes new bone tissue
Compact bone.
Cancellous bone makes up about 20 percent of the human skeleton, providing structural support and flexibility without the weight of compact bone. It is found in most areas of bone that are not subject to great mechanical stress
Cortical bone tissue makes up the dense hard outer layer of bone. It is also known as compact bone and provides structure and protection to the inner spongy bone tissue.
The skeleton of an embryo is originally made of cartilage, a flexible tissue that later undergoes ossification to become bone. During development, the cartilage is replaced by bone in a process known as endochondral ossification.
