Bones provide the structure for our bodies. The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs. Bones are made of connective tissue reinforced with calcium and specialised bone cells. Most bones also contain bone marrow, where blood cells are made.

The skeleton of the human body is made up of bones, which provide support, protection, and shape to the body. It also helps in the movement of the body, along with other important functions such as producing blood cells and storing minerals.

The human skeleton is divided into two main parts: the axial skeleton and the appendicular skeleton.

Axial Skeleton:

1. Skull: The skull is made up of several bones that protect the brain and sensory organs such as the eyes and ears.

2. Spine: The spine, also known as the vertebral column, is made up of a series of small bones called vertebrae. It provides support to the body and protects the spinal cord.

3. Ribs: The ribs are long, curved bones that form a protective cage around the chest. They are attached to the spine at the back and to the sternum (breastbone) at the front.

4. Sternum: The sternum is a flat bone located in the middle of the chest. It connects the ribs and provides support to the chest.

Appendicular Skeleton:

1. Arms: The arm bones consist of the humerus in the upper arm, the radius and ulna in the forearm, and the carpals, metacarpals, and phalanges in the hand.

2. Legs: The leg bones consist of the femur in the thigh, the tibia and fibula in the lower leg, and the tarsals, metatarsals, and phalanges in the foot.

3. Pelvis: The pelvis is a ring-like structure formed by the hip bones. It connects the spine to the legs and supports the weight of the upper body.

4. Shoulder Girdle: The shoulder girdle consists of the clavicle (collarbone) and scapula (shoulder blade). It connects the arms to the axial skeleton.

Overall, the skeleton of the human body is a complex structure made up of bones that provide support, protection, and enable movement. It plays a crucial role in maintaining the body's shape and allowing various activities such as walking, running, and lifting objects.
