Arytenoid Chondritis   (Site not responding. Last check: 2007-10-29) Arytenoid chondritis or chondropathy is a disease affecting the upper airway of  the horse. Arytenoid chondritis is diagnosed using endoscopic examination in which a small camera enclosed in a tube is passed up the horse’s nasal passage in order to visualize the arytenoids. Arytenoid chondritis should be considered especially in performance horses that exhibit exercise intolerance and inspiratory noise. evrp.lsu.edu /healthtips/Arytenoid_Chondritis.htm   (850 words)

Larynx - ninemsn Encarta The skeletal structure of the larynx is made up of three large cartilaginous structures, the epiglottis, thyroid cartilage, and cricoid cartilage, and of several pairs of small cartilages, the most important of which are known as arytenoid cartilages. Below the false cords are the true vocal cords, extending from the arytenoid cartilages to the angle of the thyroid cartilage. The pitch of the sound is voluntarily controlled by muscles that rotate the arytenoid cartilages towards the centre of the body (slackening and lengthening the cords) for low tones, and towards the sides of the body (shortening the cords and pulling them taut) for high-pitched tones. au.encarta.msn.com /encyclopedia_761563511/Larynx.html   (630 words)

JNL 4: A CINEFLUOROGRAPHIC PILOT STUDY OF THE THROAT WHILE VIBRATO TONES ARE PLAYED ON FLUTE AND OBOE Within the cartilage structure are the arytenoid cartilages which are able to move in a variety of ways they can glide medially and laterally as well as rotate, and may slide forward and backward with restricted movements. They are opened and closed by action of the arytenoid cartilages and are used both as a "valve" to stop air from escaping from the trachea and to produce speaking and singing sounds. Arytenoid and aryepiglottic fold motion of subjects four and six was not shown on the tracings. www.zainea.com /vibrato.htm   (3371 words)

Larynx The thyrohyoid membrane was seen in the study of the neck and is pierced by the internal laryngeal nerve and superior laryngeal artery. It extends from the upper border of the thyroid cartilage to the greater wing of the hyoid bone.

Laryngeal Hemiplegia - The Merck Veterinary Manual Diagnosis is confirmed by endoscopic observation of reduced or absent mobility of the arytenoid cartilage and vocal fold. With laryngeal hemiplegia, the arytenoid cartilage and vocal fold are located in a median position within the laryngeal lumen and are immobile. The axial (medial) surface of the arytenoid cartilage may be distorted with granulation tissue protruding through the mucosa, and a contact (kissing) lesion may be present on the contralateral arytenoid cartilage. www.merckvetmanual.com /mvm/htm/bc/121313.htm   (645 words)

Left Recurrent Laryngeal Hemiplegia Roaring As a result, the arytenoid cartilage and vocal cord on the left side of the larynx collapse and are sucked into the airway during exercise. If the arytenoid cartilage and vocal cord are observed to collapse into the airway during strenuous exercise on a high speed treadmill, then a diagnosis of left recurrent laryngeal hemiplegia is confirmed. The laryngeal ventricles are outpouchings of mucosa bounded medially by the arytenoid cartilages and vocal cords. www.netpets.org /horses/reference/gencare/roar.html   (805 words)

Organs of Voice and Respiration The lower border of the cricoid cartilage is horizontal, and connected to the upper ring of the trachea by fibrous membrane. This cartilage is sometimes united to the arytenoid, and serves to prolong it backwards and inwards. The ligaments connecting the arytenoid cartilages to the cricoid, are two thin and loose capsular ligaments connecting together the articulating surfaces, lined internally by synovial membrane, and strengthened behind by a strong posterior crico-arytenoid ligament, which extends from the cricoid to the inner and back part of the base of the arytenoid cartilage. vr-organs.org /1a.php   (1346 words)

Glossary Arytenoid cartilages - Small cartilages that sit atop the back of the cricoid cartilage and hold the back end of the vocal folds. The arytenoid cartilages can rock, glide, and pivot, thus controlling the movement of the vocal folds. They pull the thyroid cartilage down and forward on its hinge, which increases the distance between the arytenoids and the thyroid notch, thereby lengthening and tightening the vocal folds; this causes them to vibrate faster, thus raising pitch. www.lionsvoiceclinic.umn.edu /page9.htm   (2757 words)

ARYTENOID, CORNICULATE, & CUNEIFORM CARTILAGES At the superior tip of each arytenoid cartilage is a small, corniculate cartilage. The movement of the arytenoid cartilages controls the length and position of the vocal folds, which are attached to the arytenoid cartilages. Two, small cuneiform cartilages support the soft tissues of the aryepiglottic folds that connects the arytenoid cartilages to the epiglottis. www.getbodysmart.com /ap/respiratorysystem/larynx/smallcartilages/tutorial.html   (72 words)

Medscape MEDLINE search: Arytenoid ... Arytenoid mucosal injury in young Thoroughbred horses--investigation of a proposed aetiology and clinical significance. Arytenoid adduction is a phonosurgical procedure in which the arytenoid cartilages are approximated to reduce posterior glottal gap size and improve voice. Arytenoid subluxation is a well-known cause of hoarseness due to incomplete glottic closure with intact inferior laryngeal nerves after severe laryngeal trauma. search.medscape.com /uslclient/searchMedline.do?queryText=Arytenoid+...   (1138 words)

Treatment of Unilateral Adductor Vocal Cord Paralysis The epiglottic cartilage forms the anterior wall of the larynx.  Its primary importance in protecting the airway during deglutition. The corniculate cartilages are cone shaped and sit directly on top of the arytenoid cartilages.  The cuneiforms are found in the aryepiglottic fold.  Their primary role is to provide elastic force to separate the medialized aryepiglottic folds.  If there is any fixation of the arytenoid cartilages, a nerve anastomosis should not be used.  This procedure cannot be performed on a patient who has had disruption of the ansa cervicalis, either by surgery, trauma, or neurological process. www.utmb.edu /otoref/Grnds/VC-paralysis-001108/VC-paralysis-001108.htm   (2459 words)

PHONATION - PRODUCTION OF VOICE SOUNDS   (Site not responding. Last check: 2007-10-29) The intrinsic muscles adjust the position and tension of the vocal folds by moving the arytenoid cartilages. Voice pitch is determined by the tension applied to the vocal folds by the arythenoid cartilages. Pitch decreases when the vocalis and thyroarytenoid muscles move the arytenoids forward and the vocal folds are loosened. getbodysmart.com /ap/respiratorysystem/larynx/phonation/tutorial.html   (151 words)

CFV - How the Larynx (Voice Box) Works   (Site not responding. Last check: 2007-10-29) There are several sets of muscles that attach to the arytenoid cartilages, and by their contraction, can move the arytenoids and along with them the posterior part of the vocal folds. The lateral cricoarytenoid and interarytenoid muscles pull the muscular processes of the arytenoids and the vocal folds to the center of the glottis, thus closing it (adduction). Because the arytenoid cartilages are attached to the back of the cricoid cartilage, and the vocal folds are attached to the thyroid and arytenoid cartilages, this rotational movement causes longitudinal stretching of the vocal folds. www.voice.northwestern.edu /howworks.html   (1567 words)

Intubation of the Feline   (Site not responding. Last check: 2007-10-29) Two percent lidocaine is used topically to facilitate relaxation of the arytenoid cartilages. After the cat is positioned in sternal recumbency with the tongue pulled out and the head and neck pointed toward the ceiling, place one drop of 2% lidocaine on each arytenoid cartilage using a tuberculin syringe without a needle. If the arytenoid cartilages are closed, gently rotate the tube using the bevel of the tube to open the cartilages. cvm.msu.edu /services/aneth/docs/cat-intu/index.htm   (1285 words)

D.C. Vets, Inc. - Laryngeal Paralysis The remaining muscle (cricoarytenoideus dorsalis) functions to open the laryngeal portion of the airway by abducting (pulling open) the arytenoid cartilages when we inspire. An arytenoid lateralization is a procedure that uses sutures to hold the laryngeal portion of the airway open. The suture is passed through the arytenoid cartilage to the outside of the larynx and tied. www.dcvets.org /surgical/LaryngealParalysis.htm   (585 words)

Larynx Summary The structure of the larynx is mainly composed of cartilage bound by ligaments and muscle. The inferior horns (protrusions at the bottom rear of the thyroid cartilage) of the thyroid cartilage rest on a ring-shaped cartilage called the cricoid cartilage which connects the larynx to the trachea. While articulation of the sound (the fine manipulation that creates the many different vowel and consonant sounds of the world's languages) is achieved by the use of the teeth, tongue, palate, and lips, sound is generated in the larynx, and that is where pitch and volume are manipulated. www.bookrags.com /Larynx   (1438 words)

[No title] Portions of the pharynx lie posterior to the nasal cavity (nasal pharynx), oral cavity (oral pharynx) and larynx (laryngeal pharynx). Since the vocal cords are attached to the arytenoid cartilages posteriorly and the thyroid cartilage anteriorly, regulation of vocal cord tension (and therefore pitch of the voice) is accomplished primarily by pivoting the thyroid cartilage forward or backward at the cricothyroid joint (Figure 51. Abduction of the vocal cords may be accomplished either by externally rotating the arytenoid cartilages on a pivot located at the angle of the "L" (center panel, Figure 6), or by sliding the 2 arytenoid cartilages apart slightly (right panel, Figure 6). www.emory.edu /ANATOMY/AnatomyManual/pharynx.html   (2077 words)

CHA 400/200 - The Larynx The thyroid cartilage has superior and inferior horns, which are attached to the hyoid bone and cricoid cartilage, respectively. These ligaments are attached to the medial edges of the thyroid cartilage laminae and to the vocal processes of the arytenoid cartilages. This inlet is bounded by the epiglottis, the aryepiglottic folds, the arytenoid cartilages, and the mucosa between the arytenoid cartilages. omeweb2.ucdavis.edu /QuarterCD/Fall05Q1/Anatomy/Lectures/Lec30-Larynx.htm   (1209 words)

Sound producing muscles The larger laryngeal cartilages are - the thyroid (shield shaped), cricoid (ring like) and arytenoid (pitcher shaped) cartilages. They are moved by several muscles and the position of cartilages is quite important in all modes of phonation. They are - intrinsic muscles that interconnect various cartilages of the larynx, and extrinsic muscles connecting larynx to other structures around the larynx. www.suite101.com /article.cfm/our_beautiful_bodies/97142   (409 words)
