A cross-section of a human body specifically the pelvis and the brain stem. On the left side of the image there is a diagram of the aura which is a type of nerve that is responsible for regulating the flow of blood from the brain to the spinal cord. On the right side there are two nerves one labeled "Vessel 5-HT1B" and the other labeled "Trigeminal ganglion". The aura is located in the center of the body and is connected to the brain by a series of wires. The wires are labeled with the names of the nerves including "C1" "C2" and "Brain stem". The diagram also shows the trigeminal nerve which helps to regulate the blood flow in the brain. The nerve is located at the top of the head and neck and the nerve is attached to the neck and neck muscles. There is also a label on the image that explains the different types of nerves and how they interact with each other. The diagram also includes a label that explains how the nerve can be used to control the flow and regulate the flow rate of blood.
