The brain, the central part of the nervous system, is the main organ of humans.

• sensory, thanks to which we see,

ness.
Information received and sent by the brain travels along the nerves. The brain is connected to the spinal cord, which runs inside the spine. Nerves that arise from the brain and spinal cord penetrate the entire body.
Nerves transmit information from organs to the brain and back. Thanks to the sensory nerves of the eyes and ears, we are able to see and hear. Other nerves carry commands from the brain to the muscles, resulting in movements of the legs and arms.
Integrated brain functions are more complex. We usually maintain a sense of orientation while in a state of alertness or consciousness. A sense of orientation actually means that we know who we are, where we are, what time and day it is, and what is happening around us at the moment. But the level of consciousness may be different. For example, a person who has suffered a head injury may be conscious but confused when asked to say their name or tell what happened.
