The human body consists of a bony skeleton and muscles. The three main parts of the body are: the head, the trunk and the limbs (extremities).
The head is composed of the cranial and facial parts. It contains the brain, the centre of the nervous system. The cranium is partly covered with hair. The parts of the face are the forehead, the temples, the ears, the eyes with eyebrows, the cheeks, the nose, the jaw, the mouth and the chin. The main parts of the mouth are lips, the tongue, the teeth, the palate and the gums. The eyes are protected by eyelids and eyelashes. The eyes are the organs of sight. The nose of smell, and the ears are the organs of hearing. The nerves of the skin are organs of touch. The five senses are: sight, hearing, smell, taste and touch.
The head is attached to the trunk by the neck. The trunk includes the chest (in front), the back, the shoulders and the abdomen. The internal organs which we cannot see, are the heart, the lungs, the stomach, the liver with the gall-bladder, the pancreas, the spleen, the kidneys and the small and large intestines (bowels).
The arms and legs are called the limbs. The upper extremity (arm) consists of the upper arm, the elbow, the forearm, the wrist and the hand with four fingers and one thumb. The inner side of the hand is called the palm. The finger nails protect the finger tips.
The lower extremity (leg) is attached to the pelvic girdle. It is composed of the thigh, the knee with patella, the shin, the calf, the ankle and the foot. Each foot has a heel, a sole and five toes.
The movement of the body is produced by the expansion and contraction of the muscles. The muscles are connected with the bones by sinews, the bones are bound together by ligaments. Organs of the body are positioned within spaces called cavities.There are these cavities in the human body: cranial, spinal, thoracic, abdominal and pelvic.
