Nervous System The two types of the nervous system are the Central nervous system and the peripheral nervous system. They are responsible for integrating‚ processing‚ and coordinating Sensory data and motor commands the central nervous system‚ which interprets sensory input and carry information to maintain homeostasis. CNS can’t be regenerate because a CNS consists of the spinal cord that mean if it’s break the spinal cord is break also. The peripheral nervous system consists of the nerves

CENTRAL NERVOUS SYSTEM Every behavior begins with biology. Our behaviors‚ as well as our thoughts and feelings‚ are produced by the actions of our brains‚ nerves‚ muscles‚ and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being‚ including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it works

The nervous system consists of the brain‚ spinal cord‚ and a complex network of neurons. This system is responsible for sending‚ receiving‚ and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let ’s take a look at the central nervous system. Central Nervous System The

The Nervous System is the system of cells‚ tissues‚ and organs that regulates the body’s responses to internal and external stimuli. In vertebrates it consists of the brain‚ spinal cord‚ nerves‚ ganglia‚ and parts of the receptor and effector organs. Your nervous system is composed of the central nervous system‚ the cranial nerves‚ and the peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerves connect the brain to the head. The four groups of nerves

NERVOUS SYSTEM 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. The brain and spinal cord form the control center known as the central nervous system (CNS)‚ where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions

-We have 2 parts in our nervous system: The central nervous system (CNS) is the nerves in our brain and spinal chord. The peripheral nervous system (PNS) is a network of nerve cells in the rest of our body. -Our nervous system detects stimuli and allows us to react to them. -Stimulus: a change‚ action or occurrence in the environment that can cause an organism to respond. Eg. Light‚ noise‚ pressure… How do we detect stimuli? -We have sensory organs that detect particular stimuli eg. Skin What

Neurons and nervous systems Communication around the body Neurons - the basic building blocks of the nervous system‚ soecialised to communicate info around the body Three different types of neurons sensory neurons (afferent) : transfer info from the body to the brain Motor neurons (efferent) : transmit info from brain to the body Interneurins : communication b/w sensory and motor neurons Structure communication with a neuron Communication within neurons is an electrochemical process

The Nervous System The nervous system is the most complex part of the body‚ as they govern our thoughts‚ feelings‚ and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease‚ stroke‚ accidents‚ etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous

he nervous system is the communication network of the body. It consists of a complex collection of nerves and specialized cells‚ called neurons‚ that transmit messages across the different parts of the body in order for it to function and react correctly. They are known as the building blocks of the nervous system. Structurally they have long extensions that extend out from the cell body. There are two types of these extensions; dendrites‚ which are extensions of the neurons that receive signals
