Q

What is the lingual nerve?

A

A branch of the mandibular division of the trigeminal nerve
It also carries the chorda tympani nerve of the facial nerve, which provides special sensation (taste) to the anterior 2/3 part of the tongue

17
Q

What is the nerve supply of the oropharynx?

A

Pharyngeal plexus (CN IX-X)

18
Q

What arteries and nerve supply the hypopharynx?

A

Superior Thyroid Artery, Lingual Artery & Ascending Pharyngeal Artery
Pharyngeal plexus

19
Q

What are the boundaries of the hypopharynx?

A

Superior margin of epiglottis to lower border of cricoid cartilage, it is continuous with the oesophagus & the anterior wall is bordered to the back of larynx

20
Q

What are the three subsites of the hypopharynx?

A

Pyriform sinus
Post-cricoid area
Posterior pharyngeal wall

21
Q

What are the three functions of the larynx?

A

Part of the respiratory tract
Voice
Swallowing

22
Q

Where is the supraglottis and what is present there?

A

Superior tip of the epiglottis to the floor of the ventricular fold Junction of respiratory and squamous epithelium

23
Q

Where is the glottis?

A

Begins superiorly at the true vocal fold and extends inferiorly to a horizontal plane 5mm inferior to the vocal cord

24
Q

Where is the subglottis?

A

Begins 5 mm below the free edge of the true vocal cord and proceeds to the inferior border of the cricoid cartilage

25
Q

What are the three phases of swallowing?

A

Oral phase
Pharyngeal phase
Oesophageal phase

26
Q

What plexus motor innervates both layers of the tunica muscularis in the pharynx?

A

Myenteric plexus - Auerbach’s plexus

27
Q

What do intrinsic muscle of the pharynx do?

A

Regulate vocal fold movement

28
Q

What does the left recurrent laryngeal nerve loop around?

A

Aortic arch

29
Q

What is the sensory innervation of the supraglottic and glottic/sublgottic areas?

A

Supraglottic - Internal laryngeal nerve

Glottic and subglottic – Recurrent laryngeal nerve

30
Q

What are the five principles of voice production?

A

Respiration – Source of energy: Air flow
Phonation – Flow of air through different VC position, tension, vibration & length
Resonation – Oral/nasal speech balance
Articulation – Production of speech, determined by action of lips, tongue and jaw
Prosody – Production of syllable stress and emphasis
