What is the difference between the CNS and the peripheral nervous system?
Difference between the CNS and peripheral nervous system. The term peripheral nervous system (PNS) refers to any part of the nervous system that lies outside of the brain and spinal cord. The CNS is separate from the peripheral nervous system, although the two systems are interconnected. There are a number of differences between the CNS and PNS;
What is the CNS?
Share on Pinterest. The CNS is the brain and spinal cord. The CNS consists of the brain and spinal cord. The brain is protected by the skull (the cranial cavity) and the spinal cord travels from the back of the brain, down the center of the spine, stopping in the lumbar region of the lower back. The brain and spinal cord are both housed within ...
What are glial cells?
Also called neuroglia, glial cells are often called support cells for neurons. In the brain, they outnumber nerve cells 10 to 1. Without glial cells, developing nerves often lose their way and struggle to form functioning synapses. Glial cells are found in both the CNS and PNS but each system has different types.
How many spinal nerves are in the brain?
From the brainstem, where the spinal cord meets the brain, 31 spinal nerves enter the cord. Along its length, it connects with the nerves of the peripheral nervous system (PNS) that run in from the skin, muscles, and joints. Motor commands from the brain travel from the spine to the muscles and sensory information travels from ...
What is the membrane that controls the brain and spinal cord?
The brain and spinal cord are both housed within a protective triple-layered membrane called the meninges. The central nervous system has been thoroughly studied by anatomists and physiologists, but it still holds many secrets; it controls our thoughts, movements, emotions, and desires.
Which nerves are responsible for odors?
Of these 12 pairs, the olfactory and optic nerves arise from the forebrain and are considered part of the central nervous system: Olfactory nerves (cranial nerve I): transmit information about odors from the upper section of the nasal cavity to the olfactory bulbs on the base of the brain. Optic nerves (cranial nerve II): carry visual information ...

What is the central nervous system?
The central nervous system (CNS) is a division of the nervous system whose function is to analyze and integrate various intra- and extrapersonal information, as well as to generate a coordinated response to these stimuli. Put simply, the CNS is the supreme command center of the body.
What is the CNS?
Put simply, the CNS is the supreme command center of the body. The CNS consists of two organs which are continuous with each other; the brain and spinal cord. They are enveloped and protected by three layers of meninges, and encased within two bony structures; the skull and vertebral column, respectively.
What are the chief cells of the brain and spinal cord?
The chief cells of the brain and spinal cord are the neurons, which receive and transmit neural impulses . Each neuron has a body which is its micro-command center, and it has a gray color when observed microscopically. The neurons possess two or more neural processes that stem from the body and relay the neural information. The neural processes are divided into short ( dendrites) and long ( axons ). Most of the axons are ensheathed by a substance called myelin, which gives them a distinguishable white color.
How do the brain and spinal cord communicate?
While analyzing the information and preparing adequate body responses, the parts of the brain and spinal cord communicate with each other via many neural pathways. Once the final output is ready, they convey it to the rest of the body via nerves of the peripheral nervous system (PNS), which stem directly from them.
What is the function of the spinal cord?
The function of the spinal cord is to convey information between the brain and the rest of the body. In addition, the spinal cord regulates lower bodily functions independently from the brain, such as reflexes. The anatomy of the spinal cord is described in more detail below:
What is the supreme command center of the body?
The supreme command center of the body that receives, integrates, processes, and generates neural impulses that control all the bodily functions. Parts. Brain (cerebrum, cerebellum, brainstem, subcortical structures) Spinal cord.
How many parts does the cerebellum have?
The cerebellum consists of three parts; a middle vermis flanked by two hemispheres. The superior (tentorial) surface points superiorly and the inferior (occipital) surface faces inferiorly. The cerebellum is divided horizontally into three lobes (anterior, posterior, flocculonodular) and approximately ten lobules (I-X).
What is the central nervous system?
The central nervous system (CNS) consists of the brain and spinal cord. This body system is responsible for integrating and coordinating the activities of the entire body. Through these physical structures, thought, emotion, and sensation are experienced, and body movements are coordinated.
How does the CNS regulate the body?
For instance, long-term and short-term metabolism and homeostasis are regulated through close interaction between the central nervous system and the endocrine system.
What are the three membranous coverings that protect the spinal cord and brain?
These meninges are called pia mater, arachnoid mater and dura mater. Pia mater is the layer closest to the nervous tissue and dura mater lies next to the bone.
How many segments does the spinal cord have?
It can be divided into 31 segments, each giving rise to a pair of spinal nerves. Spinal nerves carry both sensory and motor signals between the body and the spinal cord. The central part of the spinal cord consists of an H-shaped grey column containing the cell bodies of spinal cord neurons.
How does the CNS affect the skeletal muscle?
Based on these stimuli, the CNS alters skeletal muscle contraction. Once infants learn to walk, this happens involuntarily, no longer requiring conscious thought or concentration. A similar process of receiving complex stimuli and generating a coordinated response is required for vastly varied activities – whether it is balancing a bicycle, maintaining a conversation or mounting an immune response.
What is the CNS response?
The CNS receives input from a variety of different sources, and implements an appropriate response to the stimuli, in a co hesive manner. For instance, in order to walk the CNS needs visual and integumentary cues – the texture of the surface, its incline, the presence of obstacles, and so forth.
Why is the CNS important?
The key to the work of the CNS is integration. It receives input from various sources and creates a cohesive response. This is particularly important for animals in complex social structures, like human beings. For instance, meeting an old friend and catching up over coffee can seem like a relaxing event.
