The rostral epidural rete mirabile of the llama as a place of retrograde transport of various substances – anatomical basics

Abstract The aim of this study was to analyse the structure rostral epidural rete mirabile in llama. Some specimens were prepared by injecting stained chemically cured acrylic into bilateral common carotid arteries. After about 1 month received vascular corrosion casts on bone scaffold. made using red and blue latex introduced arteries external jugular vein. is a well-developed, composed numerous arteries, which are multiply anastomosed with each other. cranial section asymmetrical. Its lateral part much better developed, because there branches at point. arterial vessels not accompanied homonymous veins. However, venous cavernous sinus. That plays an important role selective brain cooling, conservation body water, retrograde transport neurotransmitters. CO, GnRH, beta-endorphin, progesterone, testosterone, oxytocin, LHRH dopamine diffuse from blood sinus mirabile.
