The Intermediate Nerve Fibre (the adjustor or interneuron)‚ which interprets the signal and issues a response 4.) The Motor (efferent) Nerve‚ which then carries the response message from the spinal cord to the muscle or organ 5.)

vertebral arteries enter the cranium via the foramen magnum near the junction of the medulla and spinal cord. They run along the medulla just ventral to the olives and lateral to the pyramids. Each vertebral artery gives off an anterior spinal branch. These fuse at the midline forming the anterior spinal artery‚ which descends down the medulla onto the cervical spinal cord. The branches of the anterior spinal artery penetrate the pyramids‚ supplying a ventral wedge of the medulla that includes the pyramids

dermatome is an area of skin that is mainly supplied by a single spinal nerve. There are eight cervical nerves (C1 being an exception with no dermatome)‚ twelve thoracic nerves‚ five lumbar nerves and five sacral nerves. Each of these nerves relays sensation (including pain) from a particular region of skin to the brain. Along the thorax and abdomen the dermatomes are like a stack of discs forming a human‚ each supplied by a different spinal nerve. Along the arms and the legs‚ the pattern is different:
