HSC 350 Lecture Notes - Lecture 1: Anterior Spinal Artery, Posterior Spinal Artery, Superior Sagittal Sinus
Document Summary
The brain must maintain tight regulatory control over the delivery of oxygen, glucose and other nutrients and the removal of co2, and other metabolic products. The cerebral vasculature has unique anatomical and physiological features that protect the brain from circulatory compromise. Circle of willis (anastomosis) left internal carotid right internal carotid. Posterior circulation left vertebral right vertebral internal carotid arteries before bifurcation middle cerebral arteries (proximal) anterior cerebral arteries (proximal) anterior communicating artery (single artery) posterior communicating arteries posterior cerebral arteries (proximal) basilar artery (single artery) Blood supply of the brain can be divided into arterial territories middle cerebral arteries mca has superior and inferior divisions of cortical branches. Takes an indirect course through the lateral sulcus, along the insular cortex, and over the inner opercular surface of the frontal, temporal and parietal lobes. Supply the cortex and white matter of the medial frontal and parietal lobes, and the anterior corpus callosum.
