👉 Peror is a term used in the context of human anatomy to describe the structure that connects the spinal cord and the brain. It refers to the area of the spine where the vertebral column meets the thoracic cavity, which contains the spinal cord and the brainstem. Peror can also refer to the process by which the brainstem communicates with the rest of the body through a series of neural pathways known as periorbital ganglia or paracordium.
