In addition, the brain and spinal cord are protected by bone wraps, which are the skull and spine respectively.
 
The cavities of these organs (ventricles in the case of the brain and ependimal duct in the case of the spinal cord) are filled with a colorless and transparent liquid, which is called cerebrospinal fluid.

It consists of the anterior forebrain or brain, the midbrain or the middle brain and the rhombencephalon or posterior brain. In turn the forebrain is formed by the Telencephalon, which corresponds to the cerebral hemispheres or brain, and the Dibrain, which consists of the thalamus, the hypothalamus, the Subthalamus, the Metathalamus and the Epithalamus. 


On the other hand the Rhombencephalon consists of the Metencephalon, which corresponds to the brain and the bulge or bridge, and of the myelencephalon corresponding to the bulb or medulla oblongata. 

Altogether the midbrain, the bulge and the spinal bulb make up the brain stem or brainstem that is related to the twelve pairs of cranial nerves that are in charge of innervate the different organs of the head.

In this way, it is the region in charge of communicating the brain with the body, the communication between organism and brain is carried out by two main transmission mechanisms: the afferent function that sends nervous impulses from the trunk, the neck and the Limbs to the brain, and the efferent function that transports signals from the brain to different regions of the body.

It is a necessary structure to integrate the bodily functions, communicate them with the brain functioning and relate them with the outside world.
For this reason, not only primates but all vertebrate beings are characterized by having a spinal cord in their organism.
In this sense, there are areas of the skin called Dermatomes, which are constituted as organized segments. These segments contain their representation in the spinal cord.
Thus, depending on the excitatory or inhibitory processes present in the spinal cord, the different segments of the skin originate primary responses or spinal reflexes. These reflexes are characterized by always producing the same response to the same stimuli, without requiring more processors.
