function of the Autonomic Nervous System Introduction: The organs of our body are controlled by many systems in order to function correctly and efficiently in order to survive within the environment we live in. These include the heart‚ stomach and intestines and other vital organs and body systems. All of the systems in our body are regulated by a part of the nervous system called the autonomic nervous system (ANS). The ANS is part of the peripheral nervous system and it controls many organs

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

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

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

The nervous system is a very complex system in the body. It has many‚ many parts. The nervous system is divided into two main systems‚ the central nervous system (CNS) and the peripheral nervous system. The spinal cord and the brain make up the CNS. Its main job is to get the information from the body and send out instructions. The peripheral nervous system is made up of all of the nerves and the wiring. This system sends the messages from the brain to the rest of the body. The brain keeps the

NERVOUS SYSTEM The human body’s activities are regulated by two systems – the nervous system and the endocrine system. Although both systems control body functions‚ their methods differ. The nervous system is the body’s information gatherer‚ storage center and control system. Its primary function is to collect information about the external conditions in relation to the body’s external state‚ to analyze this information‚ and to initiate appropriate responses to satisfy certain needs; the most

-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

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
