    Area of Science:

    • Neurology
    • Human Anatomy
    • Physiology

    Background:

    • Cerebral circulation is vital for brain function.
    • Understanding its anatomy and physiology is crucial for healthcare professionals.
    • Alterations in cerebral blood supply can have significant clinical implications.

    Purpose of the Study:

    • To summarize basic concepts of cerebral circulation.
    • To describe the arterial and venous systems of the brain.
    • To apply these concepts to clinical nursing practice.

    Main Methods:

    • Review of fundamental anatomic and physiologic principles.
    • Tracing of arterial blood supply from origin to cerebral divisions.
    • Discussion of the circle of Willis, major vessels, territories, and venous peculiarities.

    Main Results:

    • Detailed overview of the anterior and posterior cerebral circulation.
    • Explanation of the circle of Willis and its significance.
    • Description of unique aspects of cerebral venous circulation.

    Conclusions:

    • Knowledge of cerebral circulation aids nurses in patient assessment.
    • Understanding blood flow helps in monitoring neurological status.
    • Predicting patient responses to cerebral blood supply alterations is enhanced.
