16
Q

2 arytenoids

A

Sits on top of cricoid, makes saddle joint. Open- close vocal folds

17
Q

2 corniculate

A

Sits on top of arytenoids (look like teeth)

18
Q

2 cuneiform

A

Floating, contained in aryepiglottic folds

19
Q

Cricothyroid joint

A

Pivot
Flat facets
Slightly concave/ complex
Slightly rotational - lengthens vocal folds

20
Q

Cricoarytenoid joint

A

Saddle
Oval facets
Rocking gliding movement- limited by tendinitis encapsulation

21
Q

Intrinsic membranes and ligaments

A

Affects movements of the cartilages
Elastic membrane that line all of the larynx
Membrane: connective tissue in the inside of the larynx

22
Q

Extrinsic membranes

A

Wrapping the outside cartilages
Major gap fillers
Do not govern movement
Thickened in middle

23
Q

Supra glottal

A

Above the glottis

24
Q

Vestibule

A

Open space at top of larynx, near epiglottis down to cuneiform

25
Ventricle
Right under ventricular folds. Space between true/ false folds
26
Subglottal
Below the glottis- bottom border of cricoid
27
Anterior commissure
Where TVF attach at front of cartilages
28
Posterior commissure
Arched space in back
29
Glottis
Open space between TVF
30
Extrinsic muscles of the larynx
Elevate it depress the larynx (move or fix larynx )
31
Suprahyoid
Muscles above hyoid bone | Elevators
32
Digastricus
"2 bellies" anterior/ posterior. Belly moves hyoid bone up and slightly forward
33
Mylohyoid
Forms floor of mouth- wide origin, deep ,helps drop jaw
34
Stylohyoid
Long/slender. Run along posterior belly Laterally Pulls back and up
35
Geniohyoid
Arises medial of mandible- anterior body of hyoid bone
36
Hyaline Cartilage
Glassy, rigid, found at end of bones. Attach ribs to sternum calcify when older
