Head
In anatomy, the head of an animal is the anterior part (from anatomical position) that comprises the mouth, the brain and various sensory organs (e.g. organs of sight, hearing, smell and taste).
The very simplest animals do not have a head, but many bilaterally symmetric forms do. In vertebrates the contents of the head are protected by an enclosure of bone called the skull, which is attached to the spine. The front of the human head is called the face.
The front (ventral) of the head, where the eyes and ears and mouth are located, is called the face. The area above the eyes is called the forehead (the front of the head). Below the mouth is the chin. Younger aged humans and some older humans heads have a continuing growing layer of hair covering the head. Most females of the human race do not lose this covering during the aging process, however some males can lose their head hair as they grow older.
Many animals have horns or tusks protruding from their head.
In most complex animals the head is joined to the rest of the body by the neck.
