|---|---|---|---|---|---|
| Thyromuscularis (Thyroartyenoid) | primarily serves as regulator of longitudinal tension, but can also act as a vocal fold adductor (Intrinsic Laryngeal Muscle, Relaxer)
🗑
|
||||
| Thyrovocalis (Thyroartyenoid) | Primarily serves as a regulator of longitudinal tension, but can also act as a vocal fold adductor (Intrinsic Laryngeal Muscle,Tensor)
🗑
|
||||
| Superior Thyroarytenoid | Tilts thyroid back to relax vocal folds; pulls muscular processes forward to aid in medial compression (Intrinsic Laryngeal muscles, auxiliary musculature)
🗑
|
||||
| posterior cricoarytenoid | the only abductor laryngeal muscle (Intrinsic Laryngeal muscle, abductor)
🗑
|
||||
| lateral cricoarytenoid | adducts the vocal folds; unopposed, will relax the folds (Intrinsic Laryngeal muscle, adductor)
🗑
|
||||
| oblique arytenoid | approximate the arytenoids for medial compression (Intrinsic Laryngeal muscle, adductor, part of "interarytenoids)
🗑
|
||||
| Transverse Arytenoid | approximate the arytenoids for medial compression (Intrinsic, adductor, "interarytenoids"
🗑
|
||||
| Cricothyroid | with thyroid anchored, elevates cricoid; with cricoid anchored, depresses thyroid; increases distance between thyroid and cricoid to increase vocal fold tension
🗑
|
||||
| Digrasticus: Anterior Belly | Elevates hyoid or depresses mandible (Extrinsic, Suprahyoid)
🗑
|
||||
| Digrasticus: Posterior Belly | Elevates hyoid or depresses mandible (Extrinsic, suprahyoid)
🗑
|
||||
| Stylohyoid | Elevates hyoid up and back (Extrinsic, suprahyoid)
🗑
|
||||
| Mylohyoid | Elevates hyoid or depresses mandible (Extrinsic, suprahyoid)
🗑
|
||||
| Geniohyoid | With mandible anchored, pulls hyoid up and forward (Extrinsic, suprahyoid)
🗑
|
||||
| Hyoglossus | Extrinsic tongue muscle; may help position larynx (Extrinsic, suprahyoid)
🗑
|
||||
| Genioglossus | Extrinsic tongue muscle; may help position larynx (Extrinsic, suprahyoid)
🗑
|
||||
| Thyrohyoid | Depresses hyoid or elevates thyroid (Extrinsic, infrahyoid)
🗑
|
||||
| Sternohyoid | Depresses hyoid; anchors hyoid when mandible is opened against resistance (Extrinsic, infrahyoid)
🗑
|
||||
| Omohyoid: Superior Belly | Prevents neck region from collapsing during deep inhalation (Extrinsic, infrahyoid)
🗑
|
||||
| Ommohyoid: Inferior Belly | Prevents neck region from collapsing during deep inhalation (Extrinsic, infrahyoid)
🗑
|
||||
| Sternothyoid | Depresses thyroid cartilage (extrinsic, misc.)
🗑
|
||||
| Inferior Pharyngeal Constrictor | Provide resonance characteristics to speech (extrinsic, misc.)
🗑
