Circle of Willis: What It Is, Anatomy, Function & Location

Circle of Willis: What It Is, Anatomy, Function & Location The Circle of Willis is a circular network of arteries located at the base of the brain, surrounding the pituitary gland and the optic chiasm. It plays a critical role in ensuring adequate blood flow within the brain by providing a collateral circulation system. This system can compensate if an artery becomes narrowed or blocked, thus helping to prevent ischemia. The Circle of Willis is formed by several major arteries: the anterior cerebral arteries, anterior communicating artery, internal carotid arteries (which continue as the middle cerebral arteries), posterior communicating arteries, and posterior cerebral arteries (which are branches of the basilar artery). Clinically, the Circle of Willis is a common site for cerebral aneurysms, which can lead to life-threatening hemorrhages if ruptured. It may also play a role in reducing the impact of strokes and can be affected by arteriovenous malformations, which can disrupt normal blood flow and increase bleeding risk. #CircleofWillis Join this channel to get access to perks:    / @learnmedicineasap   --------------------------------------------------------------------------------------------------------------------------------------------- Subscribe for more medical and health content:    / @learnmedicineasap   Check out our other helpful playlists Obstetrics and Gynecology    • Obstetrics and Gynecology   General Surgery Lessons    • General Surgery Lessons   Internal Medicine    • Internal Medicine   Child Health and Pediatrics    • Child Health and Pediatrics   Pharmacology Lecture Videos    • Pharmacology Lecture Videos   Anaesthesiology | Anesthesiology    • Anaesthesiology | Anesthesiology   Medical Parasitology    • Medical Parasitology   Infectious Diseases    • Infectious Diseases   Pathology    • Pathology   Microbiology    • Microbiology   Anatomy    • Anatomy   Ear Nose and Throat - ENT    • Ear Nose and Throat - ENT   Oral Health | Oral Hygiene | Dental Health    • Oral Health | Oral Hygiene | Dental Health   Ophthalmology | Eye Infections | Eye Diseases    • Ophthalmology | Eye Infections | Eye Diseases   Oncology    • Oncology   Sexually Transmitted Disease (STD) | Sexual Wellness & Health - Sexual Infection | STI    • Sexually Transmitted Disease (STD) | Sexua...   Women's Health    • Women's Health   Men's Health    • Men's Health   Vitamins, Minerals and their Deficiencies | Vitamin Deficiencies | Mineral Deficiencies    • Vitamins, Minerals and their Deficiencies ...   Clinical Skills | Clinical Techniques    • Clinical Skills | Clinical Techniques   Pharmacology Mnemonics    • Pharmacology Mnemonics   Internal Medicine Mnemonics    • Internal Medicine Mnemonics
