2- The vertebral arteries.

The internal carotid artery (ICA) is formed from the division of common carotid artery (CCA) which on the Rt side arises from the innominate artery and on the left side arises from the arch of the aorta The vertebral arteries originate as the first branch of the subclavian artery on each side, they pierce the atlanto-occipital membrane and dura and enters the

posterior fossa through the foramen magnum (Fig. 1) (Carpenter, 1983) .
