What Are the 4 Main Functions of the Nervous System? Sensory Information? ›

Summary. The brain and spinal cord make up the central nervous system. The peripheral nervous system is comprised of the somatic and autonomic nervous systems. The somatic nervous system transmits sensory and motor signals to and from the central nervous system.

The sensory system is the portion of the nervous system responsible for processing input from the environment. Beginning with detection through the transfer of stimuli to the central nervous system, the peripheral nerves and their associated receptors rapidly relay information.

Sensory neurons provide a bridge of changes in the outside world to the brain where the body can act consciously or unconsciously to respond to such environmental changes. Examples of sensory information include vision, smell, hearing, touch, temperature, pressure/vibration, and balance.

These are feeling safe and socially connected, energised to move in response to threat, and shutting down when we can't escape the danger; rest and digest, fight or flight, and freeze.

Fight, flight, freeze, and fawn are a broader collection of natural bodily reactions to stressful, frightening, or dangerous events. This sympathetic nervous system response dates back to our ancestors coming face-to-face with dangerous animals.

Nerves relay the signals to the brain, which interprets them as sight (vision), sound (hearing), smell (olfaction), taste (gustation), and touch (tactile perception).

Sensory system function allows organisms to perceive, respond to, and interact with their environments. Sensory perceptions include hearing, touch, taste, smell, and vision, which are known as the common five senses, but there are actually eight senses in the sensory system.

Both the brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by vertebrae , a set of ring-shaped bones. They're both cushioned by layers of membranes (called meninges) and cerebrospinal fluid.

What are the 4 pillars of CNS? ›

The four pillars of advanced practice are clinical practice, leadership and management, education, and research.

The central nervous system (CNS) is made up of the brain and spinal cord. It is part of the nervous system. The other part is the peripheral nervous system, which is made up of nerves that connect the brain and spinal cord to the rest of the body.

The central nervous system's responsibilities include receiving, processing, and responding to sensory information. See Image. Peripheral and Central Nervous Systems. The brain is an organ of nervous tissue that is responsible for responses, sensation, movement, emotions, communication, thought processing, and memory.
