The main part of the head and face is called the skull. The skull is composed of twenty-six bones. These bones form two basic parts of the skull, that is facial and cranial parts.
The bones of the skull are connected with the first cervical vertebra. The bones of the skull are connected together so firmly [ fa:mli] (крепко) that it is very difficult to separate them.
The bones of the skull form one large cavity and some smaller cavities. The large cavity is called the cranial cavity. The brain is in the cranial cavity. One of the smaller cavities is the cavity of the nose. The other two cavities are the orbits. The eyeballs are in the orbits.
Notes:

1. 
   cranial cavity — мозговая полость.
