Hint: A bone is a rigid organ that is a part of the vertebrate skeleton in animals. Bones protect the various organs of the body which produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility.
The adult human being consists of 206 bones.

Complete answer:
1st lets know briefly about bone and its functions
Bone: It is hard intercellular material.
The two main components of this material are collagen and calcium.
Bone tissue makes up the individual bones of the human skeletal system and the skeletons of other vertebrates.

Functions:
1. Provide structural support.
2. Protection of soft organs and tissues.
3. Blood forming system.
4. Mineral reservoir.

Adult humans consist of 206 bones.
Skull - including the jaw bone
Spine - cervical, thoracic and lumbar vertebrae, sacrum and tailbone (coccyx)
Chest - ribs and breastbone (sternum)
Arms - shoulder blade (scapula), collar bone (clavicle), humerus, radius and ulna
Hands - wrist bones (carpals), metacarpals and phalanges
Pelvis - hip bones
Legs - thigh bone (femur), kneecap (patella), shin bone (tibia) and fibula
Feet - tarsals, metatarsals and phalanges.

The longest bone in the human body is Femur or thigh bone.
The head of your femur fits into your hip socket and the bottom end connects to the knee.
Shortest bone in the human body is wormian bones.

Note: Joints are essential for all types of movement in the body.
Joints are points of contact between bones or between bones and cartilages.
Joints have been classified into three major structural forms:
1. Fibrous.
2. Cartilaginous.
3. Synovial.
Fibrous joints: Fibrous joints are joints connected by fibrous tissue, consisting mainly of collagen.
Cartilaginous joints: Cartilaginous joints are connected entirely by cartilage.
Synovial joints: Synovial joints allow for smooth movements between the adjacent bones.
