RETE MIRABILE CEREBRI

• It is a four sided arterial network enclosed in the diaphragma sella around the pituitary gland.
• It is formed by union of the branches of the vertebral, condyloid and meningeal arteries (anterior, middle and posterior).
• The medial branches of the cerebrospinal arteries (branches of vertebral arteries) unite, pass forwards and join the posterior end of the rete.
• The posterolateral angles of the rete mirabile cerebri receive the posterior meningeal arteries.
• Each anterolateral angle receives the anterior meningeal arteries and the middle of each lateral border receives the middle meningeal artery.
• The anastomosis of these arteries gives rise to a vascular network.
