What is the velopharyngeal port?
What is the velopharyngeal port?
The velopharyngeal port is the opening between the nasopharynx (upper part of the throat) and the oropharynx (back of the mouth).
What is the velopharyngeal mechanism?
What is the velopharyngeal mechanism?
The velopharyngeal mechanism is the coordinated action of the velum (soft palate) and the pharynx (throat) that controls the opening and closing of the velopharyngeal port.

Study Notes
Articulation: Pharynx, Velum, and Nasal Cavities
- The pharynx has three cavities: nasopharynx, oropharynx, and laryngopharynx.
- The lower boundaries of these cavities are the hard palate (nasopharynx), hyoid bone (oropharynx), and the base of the larynx (laryngopharynx).
- The nasopharynx contains the auditory tubes and the nasopharyngeal tonsil.
Velopharyngeal Function
- The velopharyngeal mechanism involves the interaction of the velum (soft palate) and pharynx to control the opening/closing of the velopharyngeal port.
- This port connects the nasopharynx and oropharynx.
- Two main roles are:
- Managing airflow to produce oral consonant sounds (requiring closed or nearly closed velopharynx).
- Managing acoustic energy flow to the oral and nasal cavities for vowel and consonant production.
Skull and Facial Bones
- Cranial Bones: temporal (2), parietal (2), occipital (1), frontal (1), sphenoid (1), ethmoid (1)
- Facial Bones: maxillary (2), palatine (2), vomer (1), inferior nasal conchae (2), lacrimal (2), nasal (2), zygomatic (2), mandible (1)
Muscles of the Velum
- Palatal Levator: pulls the velum upward and backward.
- Uvula: adds structural support for closure of the velopharyngeal port.
- Glossopalatine: brings the velum down.
- Pharyngopalatine: pulls the lateral pharyngeal walls upwards and medially.
- Palatal Tensor (or Tensor veli palatini): acts to open the Eustachian tube during swallowing.
Muscles of the Pharynx
- Superior, Middle, and Inferior Constrictors: contract to narrow the pharynx and propel food downwards.
- Salpingopharyngeus: uplifts the pharynx and opens the Eustachian tube; aids in swallowing and speech.
- Stylopharyngeus: elevates and widens the pharynx for swallowing and speech.
- Palatopharyngeus: lifts the pharynx and constricts it during swallowing; also closes the nasopharynx.
Vocal Tract
- The vocal tract begins at the glottis and ends at the lips and includes the oral and nasal passages.
- Important regions and structures include: the nasal cavity, oral cavity, pharynx, larynx, velum (soft palate; uvula), glottis, epiglottis, vocal cords, esophagus, and trachea.
- The larynx contains the glottis (space between vocal folds), epiglottis, and vocal cords, important for generating sound (speech).
- Air flows through the vocal tract to shape sounds, starting from the lungs and passing through the larynx, pharynx, oral cavity, and/or nasal cavity.
Additional Details
