What is the nervous system simple definition?
The nervous system controls everything you do, including breathing, walking, thinking, and feeling.
This system is made up of your brain, spinal cord, and all the nerves of your body.
The nerves carry the messages to and from the body, so the brain can interpret them and take action..
What are the two major divisions 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 are the characteristics of the nervous system?
Characteristics Of Nervous TissueNervous tissue makes up for the CNS and PNS of the nervous system.Contains two distinct cells – neurons and glial cells.It consists of the dendrites, cell body, axon and nerve endings.More items…
What are the function of the nerves?
Nerves are cord-like structures whose primary role is to provide a pathway to conduct electrical impulses throughout the body. It essentially relays information from one part of the body to another.
What is nervous system parts and functions?
The nervous system transmits signals between the brain and the rest of the body, including internal organs. In this way, the nervous system’s activity controls the ability to move, breathe, see, think, and more. The basic unit of the nervous system is a nerve cell, or neuron.
What are the 3 major organs of the nervous system?
The nervous system in a human is made of the brain, spinal cord, sensory organs and all the neurons that serve as communication channels between the various organs of the body.
Which part of the brain controls the nervous system?
The pons and the medulla, along with the midbrain, are often called the brainstem. The brainstem takes in, sends out, and coordinates the brain’s messages. It also controls many of the body’s automatic functions, like breathing, heart rate, blood pressure, swallowing, digestion, and blinking.
What are the three main functions of a nervous system quizlet?
Terms in this set (3)sensory input. when sensory receptors monitor changes that occur both inside and outside of the body.integration. when sensory information is interpreted and the appropriate response is taken.motor output. response that is performed by effectors- muscles or glands.
What are the two types of nerves?
The main 2 types of nerves are sensory nerves and motor nerves.Sensory nerves also known as afferent nerves, carry impulses from sensory receptors towards the brain.Motor nerves also known as efferent nerves, carry impulses away from the brain to muscles and glands.
What diseases are related to the nervous system?
Nervous system diseasesAlzheimer’s disease. Alzheimer’s disease affects brain function, memory and behaviour. … Bell’s palsy. Bell’s palsy is a sudden weakness or paralysis of facial muscles on one side of the face. … Cerebral palsy. … Epilepsy. … Motor neurone disease (MND) … Multiple sclerosis (MS) … Neurofibromatosis. … Parkinson’s disease.More items…
What is the main function of the nervous system?
At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body. It does this by extracting information from the environment using sensory receptors. This sensory input is sent to the central nervous system, which determines an appropriate response.
What is the function of the nervous system quizlet?
The primary function of the nervous system is to collect a multitude of sensory information; process, interpret, and integrate that information; and initiate appropriate responses throughout the body. Name the main parts of the nervous system.
What is nervous system and its parts?
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 is nervous system short answer?
The nervous system is a body system which sends signals around the body. It lets animals respond to what is around them. The central nervous system is the brain, the spinal cord, and nerves. … The structure of the system includes the brain and spinal cord, which together are called the central nervous system.
How do nerves work in the human body?
The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
What are the 4 main functions of the nervous system?
The four main functions of the nervous system are:Control of body’s internal environment to maintain ‘homeostasis’ An example of this is the regulation of body temperature. … Programming of spinal cord reflexes. An example of this is the stretch reflex. … Memory and learning. … Voluntary control of movement.
Why nervous system is very important?
The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.
Is eye part of nervous system?
The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet.
