Holstein ırkı sığırlarda sinus durae matris ve ekstrakranial ilişkileri üzerine makroanatomik araştırmalar

Macroanatomical investigations on the dural sinuses in Holstein bovine and their extracranial connections

Özet

Bu araştırmada, Holstein ırkı sığırlarda sinus durae matris ve extracranial ilişkileri incelendi. Bu amaçla 8 adet Holstein ırkı sığır başı materyal olarak kullanılmıştır. Materyallerin v. jugularis externa'sına mavi latex enjekte edildi. Dorsal ve ventral olarak iki sinus sisteminden oluştuğu belirlendi. Dorsal sinus sistemini: sinus transversus, sinus temporalis, sinus sigmoideus, confluens sinuum, sinus sagittalis dorsalis, sinus rectus; ventral sinus sistemini ise: sinus petrosus ventralis, sinus basilaris ve sinus cavernosus'lar oluşturduğu saptandı. V. emissaria occipitalis'in; v. vertebralis ile v. occipitalis'in extracranial ilişkisini sağladığı gözlendi. V.emissaria canalis n. hypoglossi'nin; sinus basilaris ile sinus petrosus ventralis'in extracranial ilişkisini oluşturduğu belirlendi. V. emissaria foraminis jugularis'in; sinus petrosus ventralis'in v. occipitalis ile extracranial ilişkisini sağladığı belirlendi. V. emissaria foraminis retroarticularis'in, sinus temporalis'in plexus pterygoideus ile ve dolayısıyla v. maxillaris ile extracranial ilişkisini meydana getirdiği tespit edildi.V. emissaria foraminis ovalis'in, sinus cavernosus'un plexus pterygoideus ile extracranial ilişkisini oluşturduğu gözlendi. V. emissaria foraminis orbitorotundi'nin, sinus cavernosus'un plexus ophthalmicus ile extracranial ilişkisini sağladığı belirlendi.

Abstract

In this study, the dural sinus extracranial connections, were investigated in Holstein cows. For this purpose, eight Holstein cows were used as a material. Blue latex were injected through the external juguler vein. It was determined that the dural sinus consisted of the ventral and dorsal systems. The dorsal system is composed of the transversal sinus, temporal sinus, sigmoid sinus, confluens sinuum, dorsal sagittal sinus and straight sinus. The ventral system of the dural sinus is consisted of the ventral petrosus sinus, basilar sinus and cavernosus sinus. It was observed that extracranial connection of vertebral vein and occipital vein is to be provided by occipital emissarial vein. It was determined that extracranial connection of basilar sinus and ventral petrosal sinus is to be provided hypoglossial n. canal emissarial vein. It was determined that extracranial connection of ventral petrosal sinus and occipital vein is to be provided by jugular foraminal emissarial vein. It was determined that extracranial connectioned of temporal sinus and pterygoideal plexus is to be provided by retroarticular foraminal emissarial vein. It was observed that extracranial vein connection of cavernosal sinus and pterygoideal plexus is to be provided by oval foraminal emissarial vein.It was determined that extracranial connection of cavernosal sinus and ophthalmic plexus is to be provided by orbitorotundi foraminal emissarial vein.
