Temporomandibular articulation is the highest feature that outlines the class of the mammalian and divorces mammals from further vertebra, it allows normal parting and departing of the jawbone and is needed for purposes such as mastication and speaking. Com ponents of this synovial joint between the condyle process of mandible and glenoid cavity of the temporal bone has been studied anatomically and histologically in 25 autopsies of adult males and female were examined at different Iraqi cities. Descriptions of TMJ related structures skin, parotid gland with its traversed facial nerve, all are related laterally the capsule of the joint, the fibrous connective tissue sac and lines with synovial membrane, containing synovial fluid, capsule is supported anteriorly by the fibers of the sphenomandibular ligaments and to the facial fibers of the masseter muscle .Also present study descri be rectangular masseter muscle with its dimensions (70±12mm) x (50 ±14) mm; contemporary no readings were recorded. In addition dimensions of the ovoid condyle process were 15 to 20 mm from side to side and 8to 10 mm from front to back Current study mentioned dimensions of the mandibular foss a which has been delimited by the attachment of joint capsule antereoposterior dimension was range from 24 – 38 mm and its lateral dimension from side to side was ranging from 19- 33mm, these differences between the condyle process and glenoid fossa inform us the free movement of the small condyle process within the fossa were it glide anteriorly furing protraction of the mandible and then its retraction. Measurements of different bones at different sex depict that the thickest trabeculae by its mean & standard deviation is founded in male in condyle process, 13.03+1.54, though the thinnest trabeculae is founded in female within the mandibular fossa of the temporal bone, 11.23 +0.90. Despite the fact for recorded algebraic data of the gaps, spaces were occupied by the tr abeculae displays that the widest gaps in dimension were seen in female mandibular fossa, 36.20 +0.71. While the narrowest spaces were seen between the trabeculae of condyle process bone of the mandible in male, 23.25+0.93. From current study anatomical features are grossly in agree with other anatomist descriptions, but dimensions of fossa and condyle are greater than other studies.

“…Ligaments and discal attachments are likely to be critical elements in TMJ function and dysfunction. These structures are responsible for the dynamic and static stabilization of the disc (Schmolke, 1994;Sato et al, 1996;Amor et al, 1998). Disc displacements may be a consequence of weak disc attachments and clearly involve their disruption (Osborn, 1995;McNeill, 1997).…”

Temporomandibular joint in miniature pigs: Anatomy, cell replication, and relation to loading

et al. 2002

View full text Add to dashboard Cite

The mechanical environment is a regulator of growth and adaptation of the musculoskeletal system, including joints. Although pigs (Sus scrofa) are used frequently as models for temporomandibular joint (TMJ) dysfunction, no systematic description of microanatomy exists for this species. We injected the thymidine analog 5-bromo-2Ј-deoxyuridine (BrdU) into 10-to 11-month-old miniature pigs that were undergoing measurements of TMJ bone strain. Ten hr later, the animals were sacrificed and their heads were perfused. Histological sections were used to map the distribution of replicating cells. Additional observations were made on gross dissections of jaw joints obtained from an abattoir. The pig TMJ is better supported than that of humans laterally and medially, but more vulnerable posteriorly. The posterior attachment area of the intra-articular disc is fibro-fatty rather than vascular, as in humans. Cartilage lines the articular eminence as well as the condylar surface. At the posterosuperior region of the condyle, the cartilage ends abruptly and is replaced by an invaginating, actively replicating periosteum. Almost all of the BrdU-labeled cells resided in the prechondroblastic zones. The condyle had more replicating cells than did the eminence (P Ͻ 0.02), but lateral and medial locations did not differ in either element. In sagittal sections, the condyle had more replicating cells posteriorly (P Ͻ 0.001), but no A-P differences were seen in the eminence. Comparisons of these data with data on bone strain indicate that increased loading is negatively associated with cell replication. Anat Rec 266: 152-166, 2002.

“…Con respecto al ligamento lateral, como es denominado en la TAI, en este caso coinciden con esta denominación (Langton & Eggleton;Sato et al, 1996;Buman & Lotzmann;Feneis & Dauber;Diaz Santana;Isberg;Okeson;Latarjet & Ruiz Liard;Alves & Candido;Schünke et al). Sin embargo, está muy extendido, sobre todo en artículos científicos y libros de especialidad en áreas clí-nicas y quirúrgicas de la ATM, a definir al ligamento lateral como ligamento temporomandibular (Helland; Langton & Eggleton; Feneis & Dauber; Buman & Lotzmann; Diaz Santana; Isberg; Okeson; Alves & Candido Con respecto a la zona bilaminar, esta es identificada por una variedad de autores (Parsons & Boucher; Hall et al; van der Kuijl et al; Hollender et al; Benigno et al; Zhang et al; Leonardi et al) quienes la ubican en el área retrodiscal, uniendo el disco articular a la cápsula.…”

Análisis de los Términos Utilizados en la Literatura Científica para Referirse a la Cápsula Articular y Ligamentos Articulares de la Articulación Temporomandibular

OTTONE, N. E.; BUCCHI, C. & CANTÍN, M. Análisis de los términos utilizados en la literatura científica para referirse a la cápsula articular y ligamentos articulares de la articulación temporomandibular. Int. J. Morphol., 34(1):342-350, 2016. RESUMEN:La identificación de las estructuras anatómicas con un término único, informativo y con ausencia de homónimos, entre otros principios, es la tarea primordial que lleva adelante la Federación Internacional de Programas de Terminologia Anatomica (FIPAT) perteneciente a la International Federation of Anatomical Associations (IFAA). Sin embargo, en la literatura científica, sobre todo con orientación clínica y quirúrgica, existen aún dificultades para adoptar la Terminologia Anatomica Internacional (TAI), generándose múltiples denominaciones para una misma estructura anatómica, complicando la comunicación científica. El objetivo de este trabajo fue analizar los términos utilizados en la literatura científica en relación a la cápsula articular y los ligamentos articulares de la articulación temporomandibular. Se revisaron artículos científicos y también libros de texto de anatomía general y específicos de la articulación temporomandibular. Se compararon los términos adoptados en la literatura especializada con la establecida en la TAI, identificándose los términos de la TAI más utilizados, como así también aquellos mencionados en artículos científicos y libros de texto pero no presentes en la TAI. El análisis realizado en esta investigación permitió identificar el uso de términos presentes y ausentes en la TAI, analizando su denominación, origen, inserción y función específica.PALABRAS CLAVE: Terminologia Anatomica; Cápsula articular; Ligamentos articulares; Articulación temporomandibular. INTRODUCCIÓNLa Terminologia Anatomica Internacional (TAI) (FICAT, 1998; FCAT, 2001) es la encargada de normalizar y estandarizar los términos que identifican a las estructuras anatómicas, estableciendo de esta manera un lenguaje común y uniforme que pueda ser utilizado por todos los morfólogos e investigadores en la enseñanza y la comunicación científica (Whitmore, 1999;Fuentes et al., 2014aFuentes et al., , 2014b. La TAI está en constante revisión en diversos ámbi-tos de reunión científica, como son los Simposios Iberolatinoamericanos de Terminologia Anatomica, Embryologica e Histologica (SILAT) iniciados en 2009 y continuados hasta la actualidad (Cruz Gutiérrez et al., 2010).En la literatura científica, la utilización de la TAI aún no se ha impuesto, y de esta manera surgen inconvenientes de denominación entre los distintos libros de anatomía, como así también en los artículos científicos publicados sobre la materia. Además, en la TAI también se encuentran ausentes algunos términos correspondientes a estructuras anatómi-cas cuyos hallazgos no son recientes y que son cada vez más aceptados por los investigadores y por lo tanto, necesitarían una posible incorporación a la TAI.El objetivo de esta investigación consistió en analizar la literatura científica, libros y artículos, en relaci...
