Q

Where do the taste fibers end up?

A

The brainstem
A tract called the solitary tract, surrounding the solitary tract is the solitary nucleus sending stuff to the thalamus, then to the insulary cortex

20
Q

Where do the taste fibers from the lingual nerve have their cell bodies?

A

The geniculate ganglion

21
Q

Where do the central process from the geniculate ganglion go?

A

Solitary tract

From CN 9 also

22
Q

Where does the lymph for the anterior tongue drain?

A

The submental lymph nodes

23
Q

Where does the lymph from the sides of the tongue drain?

A

The submandibular nodes

24
Q

Where does lymphmfrom the center of the tongue drain?

A

Both sides

25
Q

Where does lymph drain from posterior tongue drain?

A

The internal jugular and corotid nodes

26
Q

What is the epiglottic valleculae?

A

Connects the epiglottis and hyoid

The saliva collects here and may find squamous cell carcinomas

27
Q

What is on the posterior side of the thyroid cartilage?

A

The arytenoid cartilage

Controls movements of the vocal cords
On top of the cricoid cartilage

28
Q

Where does the epiglottis attach?

A

The thyroid cartilage

29
Q

Where do the muscles of the vocal cord attach?

A

The muscular process of the arytenoid cartilage

30
Q

What is important about the internal branch of the superior laryngeal nerve?

A

It supplies sensory to the area above the true vocal cords

31
Q

What are the three areas of the larynx?

A

The vestibule
Middle part
Infraglottic region

32
Q

What is the false vocal cord?

A

The vestibular fold

33
Q

What nerve supplies the vocal cords of the larynx?

A

The reccurrent laryngeal branch of he vagus nerve

Also sensory to below the true vocal cord

34
Q

What is the one muscle at the larynx?

A

The cricothyroid supplied by the external branch of the superior laryngeal nerve

35
Q

What is the posterior cricoarytenoid muscle?

A

On the laminar process of the cricoid cartilage

ABDUCTS the vocal cords
Supplied by the recurrent branch of the laryngeal nerve of the vagus

36
Q

What nerve stimulates he cough reflex?

A

The internal branch of the superior laryngeal nerve

37
Q

What does the hypoglossal nerve pass over?

A

The hypoglossus muscle

38
Q

What is found in the floor of the tonsillar fossa?

A

Glossopharyngeal nerve
Styloglossus muscle
Superior pharyngeal constrictor

39
Q

What is responsible for protrusion of the tongue?

A

The genioglossus muscle

40
Q

What structure boarders the oral cavity and the Oropharynx?

A

The palatoglossal fold

41
Q

What nerve innervates stylopharyngeus?

A

The Glossopharyngeal

Also the tonsillar fossa

42
Q

A

The palatoglossus

Innervated by the vagus nerve

43
Q

Which nerve is responsible for referred pain from the middle ear infections involving the tonsillar fossa?

A

The Glossopharyngeal

44
Q

Which ganglion is responsible for the sensory nerve fibers innervating the taste buds associated with the circumvallate papillae?

A

The Glossopharyngeal ganglion
