Vertebral and basilar arteries

The vertebral artery, from the first part of the subclavian artery, climbs through the foramina transversaria of C1–C6 and enters the skull through the foramen magnum; the two join at the lower border of the pons to form the basilar artery.

اہم نکات

• 1st part of the subclavian → C6–C1 foramina transversaria → foramen magnum.
• Two vertebrals → basilar at the lower border of the pons.
• Basilar → pons, cerebellum, inner ear, posterior cerebrals.
• Vertebral: 7th cervical intersegmental + post-costal anastomoses + C1 spinal branch.
• Cerebral atherosclerosis → stroke.
• Artery: intima / media (smooth muscle) / adventitia.
