What is the skeleton inside our body
The skeleton is a framework of bones that supports the body, allows movement, and protects internal organs. It is made up of 206 bones, which are connected by joints. The skeleton is divided into two main parts: the axial skeleton and the appendicular skeleton.
The axial skeleton includes the bones of the head, neck, and trunk. The bones of the head are the skull, which protects the brain, and the facial bones, which support the face. The bones of the neck are the vertebrae, which protect the spinal cord. The bones of the trunk are the ribs, which protect the chest cavity, and the vertebrae, which protect the spinal cord.
The appendicular skeleton includes the bones of the limbs and the shoulder and hip girdles. The bones of the limbs are the humerus (upper arm bone), radius and ulna (forearm bones), carpals (wrist bones), metacarpals (hand bones), and phalanges (finger bones) in the upper limb; and the femur (thigh bone), patella (kneecap), tibia and fibula (lower leg bones), tarsals (ankle bones), metatarsals (foot bones), and phalanges (toe bones) in the lower limb. The shoulder girdle is made up of the clavicle (collarbone) and the scapula (shoulder blade). The hip girdle is made up of the pelvis (hip bone).
The skeleton is a complex and dynamic structure that plays a vital role in our movement, support, and protection. It is important to take care of our bones by eating a healthy diet, exercising regularly, and getting enough calcium and vitamin D.
