Yeni Zelanda tavşanında (Oryctolagus cuniculus L.) articulatio temporomandibularis ve çiğneme kaslarının anatomisi

Articulatio temporomandibularis’i oluşturan unsurları ve çiğneme kaslarının anatomisini belirlemek amacıyla yapılan bu çalışmada 2200- 2650 g ağırlığında 10 adet Yeni Zelanda tavşanı (Oryctolagus cuniculus L.) kullanıldı. Eklemi oluşturan kemiksel unsurların (caput mandibulae ve fossa mandibularis) eklem yüzlerinin latero-medial yönde olduğu görüldü. Eklemi iki bağımsız boşluğa ayrılan discus articularis’in merkezinin çok ince, kenarlarının ise kalın şekillendiği belirlendi. Çiğneme kaslarından m. masseter ve m. temporalis üç, m. pterygoideus lateralis ve m. pterygoideus medialis iki kısım olarak tespit edildi. Articulatio temporomandibularis’in lateral, medial ve cranial kısımlarının çiğneme kasları ile kuşatıldığı, caudal kısmının ise capsula articularis ile örtüldüğü belirlendi. Articulatio temporomandibularis ve çiğneme kasları anatomisinin detayları ile belirlendiği bu çalışmanın özellikle diş hekimliği alanında çalışacak araştırıcılara yardımcı olacağı düşünülmektedir.

The anatomy of articulatio temporomandibularis and masticatory muscles in New Zealand rabbit (Oryctolagus cuniculus L.)

This study was designed to determine the elements constituting articulatio temporomandibularis and the anatomy of masticatory muscles in New Zealand rabbits (Oryctolagus cuniculus) and 10 subjects weighing between 2200- 2650 g were used for this purpose. Facies articularis of the bony structures (caput mandibulae and fossa mandibularis) forming the joint were observed in the latero-medial direction. Discus articularis separating cavum articularis into two separate cavities had a very thin center and thick edges. The masticatory muscles, m. masseter and m. temporalis, were examined in three parts, and m. pterygoideus lateralis and m. pterygoideus medialis were examined in two parts. Cranial, lateral and medial parts of the art. temporomandibularis was surrounded with masticatory muscles. Caudal part of the joint was covered only with capsula articularis. In conclusion, anatomy of art. temporomandibularis and masticatory muscles were determined in detail. Our opinion is that these results will especially aid the investigators working in dentistry.
