The superior pharyngeal constrictor is a muscle that forms part of the throat’s wall and plays an important role in swallowing and protecting the airway. An infection in this muscle can be painful and may affect your ability to swallow or speak. In this guide, we explain the basics—from the muscle’s structure and function to what causes its infection and how it is diagnosed and treated.
Anatomy of the Superior Pharyngeal Constrictor Muscle
Understanding the anatomy of the superior pharyngeal constrictor muscle is key to knowing how infections in this area can affect you.
Location and Structure
-
Location:
The superior pharyngeal constrictor is located in the upper part of the pharynx (throat), forming the outer wall that helps direct food and air. -
Structure:
It is a thin, flat muscle that curves along the back of the throat, contributing to the overall structure and function of the pharynx.
Origin and Insertion
-
Origin:
The muscle starts from several points including:-
The pterygomandibular raphe (a fibrous band in the mouth).
-
Parts of the medial pterygoid plate of the sphenoid bone.
-
The pterygoid hamulus (a hook-like projection).
-
-
Insertion:
The fibers of the muscle extend and merge into a midline raphe (a fibrous seam) along the back wall of the pharynx, allowing it to contract effectively during swallowing.
Blood Supply
-
The superior pharyngeal constrictor receives blood from small branches of the ascending pharyngeal artery and other nearby vessels. This rich blood supply is vital for healing and fighting infection.
Nerve Supply
-
This muscle is controlled by the pharyngeal plexus, a network of nerves that includes fibers from the vagus nerve (cranial nerve X) and the glossopharyngeal nerve (cranial nerve IX). These nerves help coordinate swallowing and other functions.
Key Functions
-
Swallowing:
It contracts in a coordinated wave (peristalsis) to help push food and liquid from the mouth to the esophagus. -
Speech Production:
Provides a stable platform that helps in articulating sounds. -
Airway Protection:
Works with other muscles to close off the airway during swallowing, reducing the risk of aspiration (food or liquid entering the lungs). -
Cough Reflex:
Participates in the forceful contraction during a cough, helping to expel irritants. -
Maintaining Throat Structure:
Contributes to the shape and function of the pharyngeal walls. -
Assisting in Breathing:
Although indirectly, it helps maintain the patency (openness) of the pharyngeal airway during respiration.
Types of Superior Pharyngeal Constrictor Muscle Infection
Infections in the superior pharyngeal constrictor muscle may vary based on their cause, severity, and duration. Some common types include:
-
Acute Bacterial Infection:
A sudden onset infection usually caused by bacteria. -
Viral Infection:

Fungal Infection:
Rare but possible in people with weakened immune systems. -
Abscess Formation:
A localized collection of pus within or near the muscle. -
Secondary Infection:
Infection that spreads from nearby areas such as the tonsils, teeth, or sinuses. -
