Q

What is the pathway of tears through the lacrimal ducts? If you put dye in your eye and then blow your nose, what should happen if all is normal with the ducts?

A

tears go into lacrimal puncta, then lacrimal canniculi, then lacrimal sac, then nasolacrimal duct then into inferior meatus of the nose.

Q

Kiesselbach area is located where? what is it? what supplies it? what damage occurs here?

A

rich supply of blood in the nose.
Sphenopalatine and palatine arteries, branches of the maxillary artery, superior labial artery, branch of facial artery and ethmoidal arteries and branches of opthalamic artery all supply this region. this is where nose bleeds tend to originate.

The two horns of the thyroid cartilage are called?

Q

Laryngeal prominence is also called? wider in males or females?

A

adams apple. wider in females giving a higher pitched voice.

21
Q

In males, the V of the thyroid cartilage is typically what? having what affect on their voice?

A

narrower, therefore steeper angle therefore deeper voice. opposite for females.

22
Q

the three paired cartilages in the larynx are?

A
  1. arytenoid
  2. corniculate
  3. cuneiform
23
Q

Arytenoid cartilage articulates at the top of what? most involved with moving what? Which nerve regulates this?

A

cricoid cartilage
vocal chords
CN 10 by way of recurrent laryngeal nerve (branch of vagus).

24
Q

Vocal chords stretch from?

A

thyroid cartilage in front to the arytenoid cartilage at the back.

25
Q

What is the only continuous ring of cartilage in the respiratory system? what shape are the others?

A

cricoid. others are horseshoe shaped.

26
Q

What are corniculate cartilages? what are cuneiform cartilages?

A

two small conical nodules consisting of yellow elastic cartilage.
two small elongated pieces of yellow elastic cartilages.

27
Q

What does the arytenoid cartilage sit on?

A

on top of cricoid cartilage.

28
Q

Thyroarytenoid muscle extends from what to what?

A

thyroid to arytenoid

29
Q

Vocal chords stretch from what to what?

A

thyroid to arytenoid

30
Q

cuneiform cartilage sits on top of what? corniculate cartilage sits on top of what?

A

thyroid cartilage.

arytenoid cartilage.

31
Q

opening between vocal cords is what?

A

glottis

32
Q

Which cartilage causes opening/closing of airway?

A

Arytenoid cartilage

33
Q

Two articulation points in the larynx are?

A

cricothyroid joint and cricoarytenoid joint

34
Q

What are the three blood vessels that supply the nose?

A

Ant/Post ethmoidal, Sphenopalatine and greater palatine.

35
Q

Opening into the larynx is called?

A

Vestibule

36
Q

Larynx is divided into what three areas?

A

vestibule, ventricle of larynx and infraglottic cavity (space below vocal cords, continuous with trachea).

37
Q

Innervation of larynx is done by? which is broken up into?

A

Vagus nerve.
branches into superior laryngeal nerve and inferior laryngeal (which branches off the recurrent laryngeal nerve). Superior further breaks into external and internal laryngeal nerve.

38
Q

Inferior laryngeal nerve innervates what?

A

all larynx muscles except cricothyroid muscle.

39
Q

superior laryngeal muscle innervates what?

A

only innervates cricothyroid muscle.

40
Q

Cricothyroid muscle does what in phonation? Thyroarytenoid muscle?

A

lengthens vocal cords (contracting them makes them tighter therefore higher pitch voice). shortens vocal cords (makes voice lower).

41
Q

What provides fine tuning of phonation?

A

vocalis (attached to vocal cords)

42
Q

Posterior cricoarytenoid muscle does what?

A

only one that opens gottis and only one that can cause abduction of arytenoids.

43
Q

Transverse arytenoid and lateral cricoarytenoid muscles can do what?

A

close glottis and cause adduction of arytenoids.

44
Q

What are the three phases of deglutition (swallowing)?

A
  1. Oral (food in mouth)
  2. Pharyngeal (food in throat)
  3. Esophageal (food descending toward stomach)
45
Q

Which of the three phases of deglutition is voluntary?

A

Oral

46
Q

When food reaches the pharyngeal stage (reflexive stage) what happens to epiglottis?

A

it moves downwards to block trachea (block food from getting into windpipe).

47
Q

Esophageal stage is under control of what?

A

brainstem and mysenteric plexus.

48
Q

Muscles of swallowing innervated by? what are the three muscles of swallowing?

A

Vagus nerve. (the external and internal branches of superior laryngeal nerve, inferior laryngeal and recurrent laryngeal nerves)
Superior constrictor, middle and inferior (contraction of these moves food down esophagus).
