The buccopharyngeal fascia covers which muscle and is separated from the prevertebral fascia by which potential space?
- A Pharyngeal constrictors; retropharyngeal space ✓
- B Prevertebral muscles; retropharyngeal space
- C Pharyngeal constrictors; danger space
- D Longus colli; prevertebral space
Correct answer: A. Pharyngeal constrictors; retropharyngeal space
Explanation
The buccopharyngeal fascia is a thin fascia covering the outer surface of the pharyngeal constrictors. Between the buccopharyngeal fascia and the prevertebral fascia lies the retropharyngeal space, a potential space that allows movement of the pharynx during swallowing and is a route for spread of infection (retropharyngeal abscess). The danger space lies deep to the prevertebral fascia.
