RT Book, Section A1 Chandrasoma, Parakrama A1 Taylor, Clive R. SR Print(0) ID 194016 T1 Introduction T2 Concise Pathology, 3e YR 1998 FD 1998 PB The McGraw-Hill Companies PP New York, NY SN 9780838514993 LK accessphysiotherapy.mhmedical.com/content.aspx?aid=194016 RD 2024/04/19 AB This section deals with diseases of the head and neckā€”but not the brain, which is covered in the section on the nervous system (Section XV). The main rationale of including such diverse organs as the oral cavity, salivary glands, ear, nose, pharynx, and larynx in one section is that they are included in the surgical specialty of otolaryngology. Diseases of the teeth (dental pathology, Chapter 31: The Oral Cavity & Salivary Glands) and eyes (ophthalmic pathology, Chapter 33: The Eye) form the rest of this section. The oral cavity, nose, pharynx, and larynx form the common opening of the respiratory and gastrointestinal systems and are often collectively called the upper respiratory tract.
