Q

If the right genioglossus is paralysed how will the tongue deviate on protrusion?

A

To the right (because each genioglossus causes protrusion to the opposite side)

16
Q

What innervates the intrinsic/extrinsic tongue muscles?

A

Hypoglossal (XII) innervates all except the palatoglossus

17
Q

On a transverse section of tongue how do you pick out the various muscles?

A

by attachment but if thats difficult sup -> Inf:

  • Intrinsic muscles
  • Genioglossus
  • Geniohyoid
  • Mylohyoid
18
Q

What muscles divides the submandibular gland?

A

The mylohyoid divides it into superificial and deep lobes

19
Q

What nerve innervates the salivary glands?

A

Parotid is by the IX cranial nerve (Glossopharyngeal)

Submandibular and sublingual are chorda tympani (VII)

20
Q

Name the muscles of the soft palate?

A

Palatoglossus & Palatopharyngeus
Musculus Uvulae
Tensor Veli Palatini & Levator Veli Palatini

21
Q

What nerves innervate the soft palate muscles?

A

The pharyngeal plexus innervates all except the tensor veli palatini.

Its innervated by the Mandibular division of V (V3)

22
Q

What nerves make up the pharyngeal plexus?

A

Cranial Nerves IX & X

Plus sympathetic fibres from the superior cervical ganglion

23
Q

What do the soft palate muscles do?

A

Close off the nasopharynx during swallowing

24
Q

What structure lies between the palatine arches?

A

Palatine Tonsils

25
Q

What is the vallecula?

A

A space behind the tongue but in front of the epiglottis, it can become lodged with food

26
Q

What forms the roof of the pharynx (specfically the nasopharynx)

A

The sphenoid body and the pharyngeal tonsils (Adenoids)

27
Q

Describe the muscles of the pharynx

A

Comes in 2 layers:

  • outer circular layer is made of the sup/middle/inf pharyngeal constrictors
  • Inner Longitudinal Layer is made of the stylopharyngeus, salpingopharyngeus and palatopharyngeus,
28
Q

Whats the special function of the salpingopharyngeus

A

Opening the eustachian tube during swallowing to equalise middle ear pressure

29
Q

The pharyngeal muscles are supplied by the pharyngeal plexus, but which Cr N Supplies most of the sensory or motor fibres?

A

IX - Sensory

X - Motor

30
Q

Function of the Pharyngeal Constrictor Muscles?

A

Peristalsis to propel the bolus down into the oesophagus

31
Q

Function of the Longitudinal Pharyngeal Muscles?

A

(Stylopharyngeus/Salpingopharyngeus/Palatopharyngeus)

Shorten/Widen the Pharynx

32
Q

List the lymphoid tissues of the oral cavity/pharynx

A
  • Lingual Tonsils – Post 3rd tongue surface
  • Palatine Tonsils – Between palatine arches
  • Pharyngeal tonsils (Adenoids) – Roof of nasopharynx
  • Pharyngeal Lymphoid Ring (Waldeyer’s Ring) – Around Entrance to oropharynx
33
Q

Function of the Larynx?

A

Protective inlet to Resp System

Also Contains Voice Box

34
Q

Identify the cartilages of the larynx? (clue theres 9)

A
  • Thyroid
  • Cricoid
  • Epiglottis
  • 2x Arytenoid (Triangular at sup/post border of cricoid)
  • 2x Corniculate (horns on top of arytenoid)
  • 2x Cuneiform (doesnt matter)
35
Q

Which membrane is pierced during anaphylaxis and why?

A

Cricothyroid

Its inferior to the vocal chords which swell, constricting breathing, during anaphylaxis

36
Q

What structures form the laryngeal inlet?

A

Epiglottis
Arytenoids
Corniculates
Aryepiglottic Folds

37
Q

What are the sections of the larynx?

A

Vestibule – Laryngeal inlet to Vestibular folds
Middle – Vestibular folds to True vocal chords
Lower – True Vocal chords to lower border of cricoid

38
Q

What nerves innervate the instrinsic laryngeal muscles and whats their function?

A

They determine laryngeal inlet diameter
They also constrict, abduct and adduct the vocal chords.

All innervated by the recurrent laryngeal nerve except the cricothyroid which is the superior laryngeal nerve

39
Q

What nerve provides sensory innervation to the larynx?

A

Sup Laryngeal Nerve
