cavity and oral cavity to communicate?
- Tensor veli palatini
- Blood supply to the external nose
- Pharyngeal recess
- a a groove between salpingopharyngeal fold and
posterior wall of nasopharynx
- b muscle that tenses the soft palate during swallowing. It runs from the medial pterygoid plate, sphenoid spine and auditory tube
to the soft palate. Its tendon loops around the pterygoid hamulus (of medial pterygoid plate). It is innervated by the Mandibular division of the
Trigeminal Nerve (V3).
