| | Neurological Disorders of the Larynx (Apr.1998) |
| | Covering the larynx are the infrahyoid or strap muscles as well as superficial cervical fascia and skin. | | | Even though the hyoid is not a part of the larynx, it is involved in movement of the larynx and therefore needs to be discussed. | | | The intrinsic laryngeal muscles are those that have both their origin and insertion within the larynx, where they play an important role in respiration and phonation. |

| | Hurme & Sonninen: Position of Larynx in Singing |
| | From a biomechanical point of view such diverse behavior on the part of these structures is motivated: the extreme constellations guarantee the vital function of air flow when singing at extreme pitches (which require extreme maneuvers in the laryngeal region). | | | We study the vertical (superior-inferior) and sagittal (anterior-posterior) position of the larynx in relation to the cervical spine and to the mandible; our subjects are singers producing a series of vowels spanning the musical range. | | | It may be useful to massage the neck area in general, but a more detailed analysis of the contribution of external muscles to laryngeal movements would help in getting to the root of voice problems. |

| | Anatomy & Physiology of the Larynx |
| | The larynx is suspended from the hyoid bone, which is significant in that it is the only bone in the body that does not articulate with any other bone. | | | The extrinsic muscles are described as such because they attach to a site within the larynx and to a site outside of the larynx (such as the hyoid bone, jaw, etc.). | | | The infrahyoid extrinsic laryngeal muscles work together to lower the hyoid bone and larynx. |
