The dog’s nervous system can be divided into the central nervous system and the autonomic nervous system.
The central nervous system includes the brain and spinal cord.

① The brain is located in the cranial cavity and is divided into cerebrum, cerebellum, pons and medulla oblongata. The brain is located at the forefront. Gray matter and white matter can be separated from the cross section of the brain. Gray matter is located on the periphery and is composed of many complex nerve cells. The white matter is located in the center and is mainly composed of nerve fiber bundles. The cerebellum is at the back of the brain and is smaller than the cerebrum. Its cross-section can also be divided into gray matter and white matter. There are many grooves and gyrus on the surface of the cerebellum. The pons is on the ventral side between the cerebrum and the cerebellum, and is a large white horizontal axis with a prominent center. The medulla oblongata is located in front of the spinal cord, and the lower part of the cerebellum is similar to a sphere, and connects with the spinal cord backward. There are 12 pairs of cranial nerves on the underside of the brain, mainly distributed in the head and neck.

The spinal cord is located behind the medulla oblongata and inside the spinal canal. It is a cylindrical cord and is divided into neck, chest, lumbar, and sacrum. The neck and waist of the spinal cord have spindle-shaped myelopathy, which are called cervical enlargement and lumbar enlargement, respectively. The nerves leading to the limbs are emitted from these enlargements.

The autonomic nervous system is composed of sympathetic nerves and parasympathetic nerves, distributed on the smooth muscles of the heart, blood vessels, various organs and glands, and innervates the activities of organs such as breathing, digestion, circulation and secretion.
