What nerve Innervates the palatopharyngeus muscle?
the vagus nerve
Both the palatinus and palatopharyngeus muscles receive efferent motor innervation from the pharyngeal branch of the vagus nerve.
What is the action of palatopharyngeus muscle?
The palatopharyngeus (palatopharyngeal or pharyngopalatinus) muscle is a small muscle in the roof of the mouth….
| Palatopharyngeus muscle | |
|---|---|
| Insertion | Upper border of thyroid cartilage (blends with constrictor fibers) |
| Artery | Facial artery |
| Nerve | Pharyngeal branch of vagus nerve |
| Actions | Pulls pharynx and larynx upward |
What nerve Innervates the palatoglossus muscle?
vagus nerve
This is the reason that all the other tongue muscles receive innervation from the twelfth cranial nerve (hypoglossal nerve) except the palatoglossus muscle, which is innervated by the tenth cranial nerve (vagus nerve).
What nerves innervate muscles soft palate?
The soft palate has five muscles that receive innervation by the pharyngeal plexus of the vagus nerve, except for the tensor veli palatini muscle, which is innervated by a branch of the trigeminal nerve called the medial pterygoid nerve.
What is the palatopharyngeus?
The palatopharyngeus is a muscle of both the soft palate and the pharynx. Anteriorly, the muscle fibers are attached to the hard palate, and posterior fibers are attached to the palatine aponeurosis. The anterior portion of the muscle is separated by the levator veli palatini (LVP).
What nerve Innervates levator veli palatini?
The Lesser Palatine Nerve Innervates the Levator Veli Palatini Muscle.
Where is palatopharyngeus muscle?
Where is Palatopharyngeus muscle?
Where is the Stylopharyngeus muscle located?
the pharynx
Stylopharyngeus is a paired muscle that participates in forming the lateral walls of the pharynx. It is one of three longitudinal pharyngeal muscles, the remaining ones being palatopharyngeus and salpingopharyngeus muscles. All three are located internally to the circular pharyngeal constrictor muscles.
