- Course: Medicine, Year 2, Semester 1
- Lecturer: Dr. Vijayalakshmi S B
- Learning Outcomes: Discuss blood supply to the brain and spinal cord, identify areas supplied by individual arteries, describe the Circle of Willis, define stroke, and explain the effects of focal lesions caused by strokes.
- Blood Supply to the Brain: Anterior system supplied by internal carotid arteries, posterior system supplied by vertebro-basilar arteries, connected via Circle of Willis.
- Internal carotid arteries and vertebral arteries are involved in the blood supply to the brain.
- Lecture covers the areas supplied by individual arteries and the Circle of Willis.
- Differentiation between ischaemic and haemorrhagic strokes is a key learning outcome.
- Lecture includes an explanation of the effects of focal lesions caused by strokes in major cortical functional areas.
- Detailed information on the blood supply to the brain, spinal cord, and individual brain regions is provided.
- Lecture aims to provide a comprehensive understanding of stroke causes and effects on cortical functional areas.
