Cribriform plate of the ethmoid bone.

25
Q

The holes in the cribriform plate of ethmoid bone allow passage for what nerves ?

A

Olfactory nerves from olfactory bulb on base of the brain.

What conchae is a separate bone ?

A

Inferior nasal conchae.

30
Q

The space between the roof and nasal cavity and the superior conchae is called …

A

Spheno-ethmoidal recess.

31
Q

What is the function of the nasal conchae ?

A

Moisturisation, purification and warming of the air.

32
Q

What are the 4 paranasal sinuses ?

A

Ethmoidal, maxillary, frontal, sphenoidal.

33
Q

What are paranasal sinuses ?

A

Hollow cavities in pneumatised bones.

A

Cricothyroid.

35
Q

What type of cartilage are the laryngeal cartilages made of ?

A

Hyaline (except epiglottis - elastic).

36
Q

What structure forms the boundary between the oropharynx and laryngopharynx ?

A

Epiglottis.

37
Q

What cartilage plays a role in phonation ?

A

Arytenoid - at cricoid-arytenoid joints where movement for vocal folds during voice production occurs.

38
Q

What are the three singular laryngeal cartilages ?

A

Epiglottis, thyroid, cricoid.

39
Q

What are the three paired laryngeal cartilages ?

A

Arytenoid, cuneiform, corniculate.

What joint results in change in length of vocal folds and plays role in phonation ?

A

Cricothyroid joint.

41
Q

What is the extrinsic ligament/membrane of the larynx ?

A

Thyrohyoid.
Has median and two lateral thickenings i.e. ligaments.

42
Q

What are the two intrinsic ligaments/membranes of the larynx ?

A

Quadrangular membrane i.e. vestibular ligament/fold and aryepiglottic ligament/fold.
Median cricothyroid membrane i.e. vocal ligament/fold.

43
Q

The superior free margin of the quadrangular membrane forms the … ligament/fold ?

Aryepiglottic ligament and fold.

44
Q

The inferior free margin of the quadrangular membrane forms the … ligament/fold ?

Cricothyroid (tensor) muscles.

52
Q

What is the group of intrinsic muscles of the larynx responsible for shortening the vocal folds i.e. creating lower pitch ?

A

Thyroarytenoid (relaxer) muscles.
