Study Notes
Sinuses
- Sinuses are hollow spaces located in the skull around the nasal cavity.
- There are four sinuses in total.
- One of the main functions of sinuses is to make the skull lighter.
- The cells lining the sinuses produce mucus, which has a number of important functions.
- The mucus produced by the sinuses moistens and drains into the nasal cavity.

Palate Structure
- The hard palate is a bony plate forming the roof of the mouth, situated between the upper teeth.
- The hard palate has ridges that aid in manipulating and swallowing food, as well as facilitating taste and drinking water.
Soft Palate Characteristics
- The soft palate is a soft, muscular tissue located at the back of the mouth.
- It extends from the hard palate in a caudal direction.
- The soft palate serves as a divider between the oropharynx and nasopharynx.
Soft Palate in Brachycephalic Dogs
- Brachycephalic dogs often have an excessively long soft palate.
- This elongated soft palate can cover the airways when breathing, resulting in noisy breathing.

Pharynx (Throat)
- Composed of three regions: Nasopharynx, Oropharynx, and Laryngopharynx
Nasopharynx
- Located between the nasal cavity and the caudal end of the soft palate
- Above the soft palate
Oropharynx
- Located between the oral cavity and the caudal end of the soft palate
- Below the soft palate
Laryngopharynx
- Located in front of the larynx, behind the soft palate
- Pathway of food and air cross in this region
Epiglottis
- A “V” shaped cartilage
- Prevents food from entering the trachea
Pharyngeal Tonsils
- Located in the nasopharynx
