Blood Vessels and Cerebrospinal Fluid

Overview

The brain’s blood supply and cerebrospinal fluid circulation support neural metabolism, protection and waste clearance. This section introduces the major arterial, venous and CSF pathways essential to central nervous system function.

Key Structures

Topics include arterial supply to the brain, venous drainage, dural venous sinuses, the cavernous sinus and the ventricular system.

Clinical Relevance and Learning Focus

Understanding neurovascular and CSF anatomy is essential for recognising stroke patterns, venous thrombosis, raised intracranial pressure and infections. The material supports clinical reasoning in neurology, neurosurgery and emergency care.
