| Abstract (English): | The larynx is an odd muscle-cartilaginous structure located in the sagittal plane, which belongs to the respiratory system. After analyzing the available literature, it was determined that, in the case of cattle, the thyroarytenoid muscle is poorly described and that there is no coincidence regarding its morphological characteristics. The objective of this work was to determine the origin, insertion and structure of the thyroarytenoid muscle in the bovine. Ten bovine larynges obtained at a slaughterhouse were used. The material was dissected fresh. The larynges were sectioned by the sagittal plane. The thyroarytenoid muscle was dissected to expose its origin, insertion and structure. The presence of three muscular bellies was observed on the lateral wall of the larynx. A rostral belly, fusiform, elongated which originated laterally at the base of the epiglottic cartilage and was inserted at the rostral end of the arcuate ridge of the arytenoid cartilage. A middle belly, intimately attached to the caudalbelly, flattened, quadrangular, which originated on the dorsal surface of the body of the thyroid cartilage and was inserted into the arcuate crest, lateral surface and vocal process of the arytenoid cartilage. A caudalbelly, wide and short that originated on the dorsal surface of the body of the thyroid cartilage and cricothyroid membrane and was inserted into the lateral surface and muscular process of the arytenoid cartilage. According to the results obtained, the thyroarytenoid muscle in the bovine has a more complex structure than that presented in the classical texts of comparative animal anatomy. The findings of this research provide valuable knowledge about the normal anatomy of the bovine larynx. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | La laringe es una estructura músculo-cartilaginosa, impar, situada en el plano sagital, que pertenece al sistema respiratorio. Luego de analizar la bibliografía disponible se pudo determinar que, en el caso del bovino, el músculo tiroaritenoideo se encuentra pobremente descrip-to y que no hay coincidencia respecto de sus características morfológicas. El objetivo de este trabajo fue determinar el origen, la inserción y la estructura del músculo tiroaritenoideo en el bovino. Se utilizaron 10 laringes de bovinos obtenidas en frigorífico. El material se disecó en fresco. Las laringes se seccionaron por el plano sagital. Se disecó el músculo tiroaritenoideo para exponer su origen, inserción y estructura. Se observó, en la pared lateral de la laringe, la presencia de tres vientres musculares. Un vientre rostral, fusiforme, alargado, que se originaba en lateral de la base del cartílago epiglótico y se insertaba en el extremo rostral de la cresta arqueada del cartílago aritenoides. Un vientre medio, íntimamente unido al vientre caudal, aplanado, con forma cuadrangular, que se originaba en la superficie dorsal del cuerpo del cartílago tiroides y se insertaba en la cresta arqueada, superficie lateral y proceso vocal del cartílago aritenoides. Un vientre caudal, ancho y corto que se originaba en la superficie dorsal del cuerpo del cartílago tiroides y membrana cricotiroidea y se insertaba en la superficie lateral y proceso muscular del cartílago aritenoides. Según los resultados que se obtuvieron, el músculo tiroaritenoideo en el bovino tiene una estructura más compleja que la que se presenta en los textos clásicos de anatomía animal comparada.
