In anatomy, the head of an animal is the rostral part (from anatomical position) that usually comprises the brain, eyes, ears, nose, and mouth (all of which aid in various sensory functions, such as sight, hearing, smell, and taste). Some very simple animals may not have a head, but many bilaterally symmetric forms do.Anatomically, the face stretches from the point of the chin to the roots of hair. The skin of the face is quite pliable and loose. Owing to the face's lack of deep fascia, facial wounds tend to bleed rather freely.There are five orifices on the face: two for the eyes, two nostrils, and the mouth.The blood supply to the face and indeed the most of the scalp comes mainly from the external carotid artery.
