Head has the following meanings in the field of medicine:
1. The upper or front part of an animal's body that contains
the brain, special sense organs for seeing (eyes), hearing
(ears), smelling (nose), and tasting (mouth), as well as
other structures. Most of the tissues in the head are
contained within the skull, which is a large bone that
covers and protects the brain. The skull is made of 22
bones. At birth, the skull is about half the size of an adult's
skull. Most of the changes in the skull after infancy are due
to growth of the face. The head is also known as a caput.
2. The top, front, or larger extremity, rounded or expanded, of any organ, body, or bodily
structure. An extremity is one of the ends of a long or pointed structure. This is also
known as a caput.
3. The end of a muscle that connects with the less moveable part of the skeleton. This is
also known as a caput.
4. The rounded end of a bone, usually long bones.
5. The top or front part of the body.
6. The part of a pimple, or other raised structure on the skin in which it is likely to break.
Head is also known as a caput. More than one head is known as capitis or capita. Head
comes from the Anglo Saxon word "heafod" meaning "head."
