How does nervous system works

 The great and mighty nervous system or the brain is 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 basic 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. And we’ll explore the peripheral later, but first, let’s look at the central nervous system. The central nervous system is made up of two major structures. The brain and the spinal court, 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 are the cerebral Sarah bella. Diane Sephora, the midbrain ponds, and the medulla oblongata. The first section is the cerebral. This is the largest section. It’s divided into two major hemispheres, which are right and left hemisphere, and the cerebral is further divided into four lobes, these 4 lobes are the frontal, the paradigm, the temporal and the occipital. The frontal lobe is primarily responsible for reasoning and god the parietal is primarily responsible for integrating sensory information. The temporal is primarily responsible for processing auditory information from the years, and the occipital is primarily responsible for processing visual information from the ice, the second section of the brain is the cerebellum. This is the section located in the back of the head below the cerebral and above the first cervical of the neck. It is responsible for muscle coordination, balance, posture and muscle tone. The Diane suffer line section is found between the cerebral and the midbrain. It contains two structures, the thalamus and the hypothalamus the thalamus behaves much like a relay station and direct sensory impulses to the cerebral and the hypothalamus controls and regulates autonomic nervous system functions such as temperature, appetite, water balance, sleep and blood vessel constriction and dilation. The hypothalamus also plays a role in the emotions such as anger. Fear, pleasure, pain and affection, the midbrain section is located below the cerebral at the top of the brain stem. It is responsible for certain eye and auditory reflexes. The ponds is located below the midbrain. And in the brain stem it is responsible for certain reflex actions. Such as chewing, tasting and saliva production. And the last section is the medulla oblongata. It’s the lowest part of the brain stem, and it connects with the spinal cord and is responsible for regulating heart and blood vessel functions, digestion, respiration. Swallowing, coughing, sneezing and blood pressure, it’s also known as a sinner 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 the spinal cord is the link between the brain and the nerves and the rest of the the spinal cord is divided into four different regions. The server call the rustic lumbar and the African and effort spinal nerves, which merged to form the peripheral nerves. The affairs spinal nerves are responsible for carrying information from the body to the brain and the efforts final nerves are responsible for carrying information from the brain to the body. Now within this elaborate system of nerves. Neurons and bin d rights there is a system that regulates the functions of the central nervous system, which lie outside its major components, such as the brain and the spinal court. This system is known as the peripheral nervous system and is subdivided into two smaller systems and the semantic 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, and the semantic system is also responsible for nearly all voluntary muscle movements. As well as for processing sensory 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 and the central nervous system are known as the African sensory neurons and the effort motor neurons now effort simply means conducting inward and effort means conducting outward. So just like in the spinal nerves, the African neurons take information from the nerves to the central nervous system, and the effort 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 danger, whether real or imagined, once the threat is gone, the parasympathetic brings all the systems 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 basic 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 of the nervous system are the central nervous system and the peripheral nervous system. The central nervous system is also divided into two major 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 cerebral Sarah bella Diane, suffer the midbrain ponds, and the medulla oblongata, the other half of the central nervous system is a spinal court, and the spinal cord is the link between the brain and the nerves, and the rest of your the spinal cord is divided into four different ways the cervical harassment. Lumbar and effort and effort 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 essentially the nervous system outside of the brain and spinal cord. The peripheral nervous system has been subdivided into two smaller systems called the somatic nervous system and and the autonomic nervous system. So as you can see, the nervous system is quite complex. And this is just a tip of the iceberg.
