👉 The term "carotidal" refers to a specific type of nerve, known as the facial nerve, which is responsible for supplying the eyes with visual information. The facial nerve runs from the base of the brain to the face and is divided into two main branches: the facial branch and the glossopharyngeal nerve (also known as the vagus nerve). These nerves are essential for the function of our facial muscles and allow us to move our lips, cheeks, and eyes.
