The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways, and parts of the brain involved in sensory perception.
How do sensory systems relate to the nervous system?
As a whole, the sensory nervous system detects and encodes stimuli and then sends signals from receptors, that is, sense organs or simple sensory nerve endings, to the central nervous system, that is, it transduces environmental signals into electrical signals that are propagated along nerve fibers.
Are sensory organs part of the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
What are parts of the nervous system?
The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
Are the 5 senses part of the nervous system?
The nervous system must receive and process information about the world outside in order to react, communicate, and keep the body healthy and safe. Much of this information comes through the sensory organs: the eyes, ears, nose, tongue, and skin.
What are the 5 sensory systems?
The five basic sensory systems:
- Olfactory (smell) System.
- Gustatory (taste) System.
- Tactile System.
- Tactile System (see above)
- Vestibular (sense of head movement in space) System.
- Proprioceptive (sensations from muscles and joints of body) System.
Why do we need the sensory system?
While the traditional importance of the sensory system lies in its ability to perceive external information about the world, emerging discoveries suggest that sensory perception has a greater impact on health and longevity than was previously appreciated. These effects are conserved across species.
What are the symptoms of a failure of the sensory system?
When sensory nerves have been damaged the following symptoms are common:
- Shooting pain or burning.
- Warm or cold sensations.
- Muscle weakness.
- Reduced or increased sensation.

What are the 6th Sense?
You’ve probably been taught that humans have five senses: taste, smell, vision, hearing, and touch. However, an under-appreciated “sixth sense,” called proprioception, allows us to keep track of where our body parts are in space.
What are the major subdivisions of the nervous system?
The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
What is the most important part of the nervous system?
The brain and the spinal cord make up the central nervous system. The nervous system is the most complex and highly organized body system. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.
What is the main function of nervous system?
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
What is nervous system and its function?
The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
What are two disorders of the nervous system?

What is human sixth sense?
Proprioception is sometimes called the “sixth sense,” apart from the well-known five basic senses: vision, hearing, touch, smell and taste. Proprioceptive sensations are a mystery because we are largely unaware of them.
Which body sense is most important?
By far the most important organs of sense are our eyes. We perceive up to 80% of all impressions by means of our sight. And if other senses such as taste or smell stop working, it’s the eyes that best protect us from danger.
