A function of the nervous system In this Blogs, I’m going to talk about some of the functions of the nervous system and how about these functions and organize them in my mind the nervous system performs many features that allow a person to experience their life and which create their behavior as well as any necessary.
functions of the nervous system
The high and mighty nervous system or the brain as most of us call it what makes this organ unique is that within it lies the ability for humans to know oneself this feature distinguishes and sets the human species apart from the rest of creation this ability is known as consciousness.
or intelligence to begin let’s look at the primary function of the nervous system the primary purpose is to coordinate all of the activities of the body it enables the body to respond and adapt to changes that occur both inside and outside the body now the nervous system is actually split into two parts the central nervous system and the peripheral nervous system will explore the peripheral later but first let’s look at the central nervous system the central nervous system is made up of two significant structures the brain and the spinal cord as most people know the brain is found within the cranium or skull and there are six main sections among other structures within it these six sections Function Of Nervous System
The cerebrum cerebellum diencephalon the midbrain pons and the medulla oblongata the first section is the cerebrum this is the most extensive section it’s divided into two significant hemispheres which are the right and left region and the cerebrum is further divided into four lobes these four lobes are the frontal the parietal the temporal and the occipital the frontal lobe is primarily responsible for reasoning and thought the parietal is mostly responsible for integrating sensory information.
The temporalis primarily responsible for processing auditory information from the ears and the occipitalis mostly accountable for preparing visual report from the eyes the second section of the brain is the cerebellum this is the section located in the back of the head below the cerebrum and above the first cervical of the neck it is responsible for muscle coordination balance posture and muscle tone the diencephalon section is found between the cerebrum in the midbrain it contains two structures the thalamus.
the hypothalamus the thalamus behaves much like a relay station indirect sensory impulses to the cerebrum and the hypothalamus controls and regulates autonomous nervous system functions such as temperature appetite water balance sleep and blood vessel constriction in dilation the hypothalamus also plays a role in emotions such as anger fear pleasure pain and defection the midbrain section is located below the cerebrum at the top of the brainstem it is responsible for specific eye and auditory reflexes the pons is situated below the midbrain and in the brain stem it is responsible for particular reflex actions such as chewing tasting and saliva production and the last section is the medulla oblongata it’s the lowest part of the brainstem and it connects with a spinal cord.
responsible for regulating heart and blood vessel function digestion respiration swallowing coughing sneezing and blood pressure it’s also known as the center for respiration now that we’ve covered the brain let’s take a look at the other half of the central nervous system the spinal cord the spinal cord is the link between the brain and the nerves and the rest of the body the spinal cord is divided into four different regions the cervical thoracic lumbar and the efferent and efferent spinal nerves which merge to form the peripheral nerves
The afferent spinal nerves are responsible for carrying information from the body to the brain, and the efferent spinal nerves are responsible for taking data from the mind to the body now within this elaborate system of nerves neurons and dendrites there is a system that regulates the functions of the central nervous system which lie outside its significant components such as the brain and the spinal cord this system is known as the peripheral nervous system and it’s subdivided into two smaller systems the somatic system and the autonomic nervous system the somatic nervous system is responsible for carrying motor and sensory information both to and from the central nervous system this system is made up of nerves that connect to the skin sensory organs and all skeletal muscles the somatic system is also responsible for nearly all voluntary muscle movements as well as for processing visual information that arrives via external stimuli including hearing touch and sight the structures that allow this communication to happen between the nerves throughout the body in the central nervous system are known as the afferent sensory neurons and the efferent motor neurons now afferent simply means conducting inward and efferent means conducting outward so just like in the spinal nerves the afferent neurons take information from the nerves to the central nervous system, and the efferent neurons take information from the central nervous system to the muscle fibers throughout the body the autonomic nervous system is further divided into the sympathetic nervous system, and the parasympathetic nervous system the sympathetic nervous system is vital to our survival have you ever heard of the fight-or-flight response to danger the sympathetic nervous system revs up the body when confronted with imminent danger to either defend yourself or to escape the threat the parasympathetic nervous system is the counterbalance to the sympathetic response to risk whether real or imagined once the threat is gone the parasympathetic brings all the methods of the body back to normal now at this point you should have a basic understanding of the nervous system but let’s do a quick recap the primary purpose of the nervous system is to coordinate all the activities of the body.
It enables the body to respond and adapt to changes that occur both inside and outside the body the two major parts to the nervous system are the central nervous system and the peripheral nervous system the central nervous system is also divided into two significant structures the brain and the spinal cord the brain is found within the skull or cranium and it is made up of six main sections these six sections are the cerebrum cerebellum diencephalon the midbrain pons and the medulla oblongata the other half of the central nervous system is the spinal cord, and the spinal cord is the link between the brain and the nerves and the rest of your body.
the spinal cord is divided into four different regions the cervical thoracic lumbar and afferent and efferent spinal nerves which merge to form the peripheral nerves now that we know the brain and spinal cord primarily make up the central nervous system let’s look at the peripheral nervous system the peripheral nervous system is necessarily the nervous system outside of the brain and spinal cord the peripheral nervous system is then subdivided into two smaller systems called the somatic nervous system and the autonomic nervous system so as you can see the nervous system is quite complex, and this is just the tip of the iceberg thanks for reading for more Article on the nervous system.
functions of the body for which a person is usually unaware and these functions can be categorized in different ways I like to think about the features of the nervous system is to first to divide them into two big categories that of as the basic elements of the nervous system and the higher functions of the nervous system and you could use whatever words you want it. here you could say that lower functions and the higher functions or the basic services and the complex functions but the reasons I like to use these words of it the basic features aren’t that simple they’re complex when you start to get into them and they’re not lower in a particular way either that you need the essential functions and the higher functions now dysfunction of different parts of the function of nervous system may cause different
