Fauces (throat)

Gray1014

Fauces (from the Latin word for "throat") refers to the region of the throat that is situated at the back of the mouth and leads into the pharynx. It is a crucial part of the human anatomy involved in both the respiratory and digestive systems.

Anatomy

The fauces is bordered by several important structures:

• The soft palate at the top
• The tongue at the bottom
• The palatoglossal arch (anterior pillar of the fauces) on the sides
• The palatopharyngeal arch (posterior pillar of the fauces) on the sides

The space between the palatoglossal and palatopharyngeal arches is known as the tonsillar fossa, which houses the palatine tonsils.

Function

The fauces play a significant role in both the respiratory and digestive systems. During swallowing, the soft palate elevates to close off the nasal passages, and the tongue pushes the food bolus into the pharynx. This coordinated action ensures that food is directed into the esophagus and not the respiratory tract.

Clinical Significance

The fauces can be involved in various medical conditions, including:

• Tonsillitis: Inflammation of the palatine tonsils, often causing sore throat and difficulty swallowing.
• Pharyngitis: Inflammation of the pharynx, which can extend to the fauces.
• Obstructive sleep apnea: The fauces can be a site of obstruction in this condition, leading to disrupted breathing during sleep.
