|---|---|---|---|---|---|
| there are 2 groups of muscles in the larynx, what are the 2 groups, what does each group mean, and what does each group do | show 🗑
|
||||
| show | adductors, abductors, tenser, relaxer
🗑
|
||||
| show | lateral cricoarytenoid, originates on the superior lateral surface of the cricoid moves up and back and inserts on the muscular process of the arytenoid, when contracted muscular process moves forward and vocal process comes together
🗑
|
||||
| show | transverse arytenoid, originates on lateral surface of one arytenoid and inserts on lateral surface of other arytenoid, when contracted arytenoids and vocal folds come together, interarytenoid
🗑
|
||||
| show | oblique arytenoid found on top of the transverse arytenoid, originates on posterior base of muscular process and inserts to top of the opposite arytenoid, when it contracts arytenoids come together and vocal folds are almost completely together
🗑
|
||||
| show | important for medial compression- folds come together very tightly with a lot of pressure between the folds, examples of this would be coughing or speaking loudly
🗑
|
||||
| what muscles is used in abduction | show 🗑
|
||||
| show | posterior cricoarytenoid, originates on posterior surface of the cricoid and inserts on posterior muscular process of arytenoid, when contracted it pulls muscular process apart to open vocal folds
🗑
|
||||
| what are the two glottal tensors, which has 2 parts and what are the 2 parts | show 🗑
|
||||
| muscle that has 2 parts, what are the 2 parts and what does the muscle do and what is the primary function of this muscle | show 🗑
|
||||
| show | pars recta, slightly upright muscle
🗑
|
||||
| show | pars oblique, runs at angle
🗑
|
||||
| show | cricoid and thyroid pull together and vocal folds tense and lengthen
🗑
|
||||
| muscles of the vocal folds themselves, where do they originate and insert, what happens when they contract (tension and length), what is another name for them | show 🗑
|
||||
| show | thyromuscularis, when contracts the vocal folds come together and lengthen but when the medial fibers contract the vocal folds relax
🗑
|
||||
| relaxer that originates on the thyroid angle and inserts on the muscular process, what is unique about this muscle | show 🗑
|
||||
| show | diagoastric muscle, stylohypid, mylohyoid, geniohyoid, hyoglossus, and genioglossus- they all pull up the hyoid/larynx
🗑
|
||||
| what are the 2 types of extrinsic muscles, what does each type mean and what is another name for both groups | show 🗑
|
||||
| show | it moves up with high pitch and down with low pitch
🗑
|
||||
| show | diagastricus anterior goes from mandibular symphyis to the hyoid and diagasticus posterior goes from mastoid to hyoid, makes a sling in the middle where the 2 bellies attach
🗑
|
||||
| show | both-hyoid/larynx goes up anterior-larynx/hyoid goes forward posterior- larynx/hyoid moves back
🗑
|
||||
| muscle that takes almost the same path as the diagastic posterior and it goes medially downward from the styloid process to the hyoid corpus | show 🗑
|
||||
| show | styloid process
🗑
|
||||
| this is the floor of the oral cavity, originates on inner lateral surface of mandible and inserts on the corpus hyoid, is also known because it is "fanlike" | show 🗑
|
||||
| muscle that starts near the chin and goes back to connect to the hyoid at the corpus, found under the mylohyoid there are 2 of them | show 🗑
|
||||
| what do the mylohyoid and geniohyoid do when they contract | show 🗑
|
||||
| show | diagastric muscle, mylohyoid, geniohyoid
🗑
|
||||
| what does glossus mean | show 🗑
|
||||
| muscles that originates on superior surface of greater cornu of the hyoid then curves up and around into the sides of tongue | show 🗑
|
||||
| show | genioglossus
🗑
|
||||
| show | the suprahyoid muscles which are diagastiric, stylohyoid, mylohyoid, geniohyoid, hyoglossus, and genioglossus
🗑
|
||||
| show | lateral cricoarytenoid, transverse arytenoid, oblique arytenoid
🗑
|
||||
| show | posterior cricoarytenoid
🗑
|
||||
| what are the tensor muscles | show 🗑
|
||||
| show | thyromuscularis, superior thyroarytenoid
🗑
|
||||
| show | intrinsic-lateral cricoarytenoid, transverse arytenoid, oblique arytenoid, posterior cricoarytenoid, cricothyroid(pars recta & oblique), thyrovocalis, thyromuscularis, superior thyroarytenoid extrinsic-diagastric,stylo,mylo, genio,hyogolssus,genioglossus
🗑
|
||||
| show | diagastric, mylohyoid, stylohyoid, geniohyoid, hyoglossus, genioglossus
