What nerve innervates the stylopharyngeus muscle? |
CN 12 Hypoglossal (All other pharyngeal are vagus) |
This is the only pharyngeal muscle not innervated by vagus nerve |
|
|
What are the suprahyoid muscles and what is their innervation? |
Muscles: Stylohyoid, mylohyoid, digastric, and geniohyoid. Innervation: CN7 Facial - Stylohyoid and post. Belly digastric. CN5 v2 nerve to mylohyoid - Mylohyoid and ant. Belly digastric CNXII Glossopharyneal - Geniohyoid |
There are 4 muscles and 3 nerves that innervate. |
|
|
What are the infrahyoids muscles and what innervates them? |
Muscles: Omohyoid, sternohyoid, sternothyroid, and thyrohyoid.
Innervation: Ansa cervicalis - ALL except thyrohyoid CNXII Hypoglossal - Thyrohyoid |
4 muscles and 2 nerves (one muscle is innervated separately from rest) |
|
|
Which laryngeal muscle is NOT innervated by the recurrent laryngeal nerve? |
The Cricothyroid muscle
(This is larynx not pharynx and cricothyroid is most superior/anterior) |
|
|
|
Which laryngeal muscle is NOT innervated by the recurrent laryngeal nerve? |
The Cricothyroid muscle
(This is larynx not pharynx and cricothyroid is most superior/anterior) |
|
|
|
What nerve innervates the laryngeal muscles and what is the exception? |
Laryngeal Innervation = Recurrent laryngeal nerve
Exception = Cricothyroid (superior laryngeal nerve) |
Consider the anatomy of the larynx |
|
|
Which laryngeal muscle is NOT innervated by the recurrent laryngeal nerve, and what does innervate it? |
The Cricothyroid muscle, innervated by the superior thyroid nerve (but still vagus)
(This is larynx not pharynx and cricothyroid is most superior/anterior) |
|
