This is the Circle of Willis 🧠 a vital arterial ring at the base of the brain.
It’s nature’s backup plan: if one part gets blocked or narrowed (like in a stroke), this loop can reroute blood flow to protect brain tissue.
Want to know a cool fact? Despite its importance, less than half of people actually have a complete Circle of Willis!
This specimen shows just how intricate our neurovascular anatomy truly is.
