Phonation Muscles and Other Structures Flashcards
Thyroid cartilage has both ___ and ___ horns
inferior; superior
Most inferior cartilage in larynx
cricoid
Arytenoids on the superior surface of the ____ cartilage
cricoid
The ____ cartilages sit on top of the arytenoid cartilages
Corniculate
goes from inferior portion of hyoid bone to superior portion of thyroid body
thyrohyoid membrane
goes from superior horn of thyroid cartilage to ends of hyoid bone
Lateral thyrohyoid ligament
runs down center of hyoid bone to near the thyroid notch
Median thyrohyoid ligament
this ligament connects epiglottis to hyoid bone
hypoepiglottic
connect inferior-most portion of epiglottis to inner surface of thyroid cartilage
Thryoepiglottic ligament
these ligaments connect the epiglottis to root of tongue
Lateral and median glossoepiglottic ligaments
This ligament attaches the trachea to the larynx
Cricotracheal ligament
This group of ligaments connect larynx cartilages and form support structure for cavity of larynx and vocal folds
intrinsic ligaments
These four things make up the fribroelastic membrane
quadrangular membranes
aryepiglottic folds
conus elasticus
vocal ligament
where is the thyroid gland in relation to the larynx?
hugging its side and inferior to it
false vocal folds made from
quadrangular membranes and vestibular ligament
the __ __ start at the epiglottis and thyroid, then go down in a cone shape at attach near the arytenoids
quadrangular membranes
cuneiform cartilage is inside the ___ ___
quadrangular membranes
The vocal ligament is made up of these two VF layers
ILP + DLP
what are the five layers of the vocal folds from superficial to deep?
1) squamous epithelium
2) SLP
3) ILP
4) DLP
5) TA muscle
this layer of the VF is made of epithelial tissue and helps with fluid retention
squamous epithelium
these two VF layers are cross-layered and made of elastin fibers
SLP and ILP
this layer of the VF is made of collagen fibers. Its role is to support the upper layers
DLP
in VF layers, what does SLP stand for?
superficial lamina propria
in VF layers, what does ILP stand for?
intermediate lamina propria
in VF layers, what does DLP stand for?
deep lamina propria
these two layers of the VF constitute the vocal ligament
ILP and DLP
what is the function of the vocal ligament?
stiffness and support to vocal folds
