Part 8: The head and neck

The cervical vertebrae and the back of the neck have already been described. In this part the skull is examined, followed by the brain, ear, and eye, and ending with the mouth, nose, pharynx, and larynx. Included in the head and neck are a number of important structures, the diseases of which form the subject matter of various specialties: neurology, neurosurgery, and neuroradiology (brain, nerves, and skull), ophthalmology (eye), otology (ear), rhinolaryngology (nose and throat), and dentistry and oral surgery (teeth and jaws).

Acquaintance with the parts of the brain and with the names of the cranial nerves is a necessary preliminary to a study of the head and neck.

The main divisions of the brain (encephalon) are the forebrain (prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon). Important subdivisions are listed in table 43-1 and illustrated in figure 43-1.

Cranial nerves are encountered in each of the chapters that follow. Their names are:

1. Olfactory

2. Optic

3. Oculomotor

4. Trochlear

5. Trigeminal: ophthalmic, maxillary, and mandibular nerves

6. Abducent

7. Facial (including the nervus intermedius)

8. Vestibulocochlear: vestibular and cochlear parts

9. Glossopharyngeal

10. Vagus

11. Accessory: internal branch (cranial part) and external branch (spinal part)

12. Hypoglossal

Further details are provided in table 43-2.
