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

1. Describe the general structure and function of the nervous system. The Nervous System is a "network" which delivers information and monitors the processes taking place in our bodies at all times. The nervous system in all its aspects allows us to function as a single controlled and coordinated unit. The basic nerve cell nerve cell is a neuron; a chain of neurons is actually a "communication cable "inside our bodies. Neuron structure is basically the cell nucleus‚ the dendrites which receive information

THE 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

Chapter 12: Nervous Tissue - The nervous system includes all nervous tissue in the body -Neural tissue contains two types of cells: 1) neurons (10% of all neurons‚ conduct nerve impulses) 2) neuroglia (support neurons) -We have 100 billion neurons -Organs of the nervous system: brain‚ spinal cord‚ sensory receptors of sense organs (eyes‚ ears‚ etc.)‚ and nerves (connects the nervous system with other systems‚ bundle of neurons that relay information) -Functions of the nervous system: 1) sensory

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

The Structure & 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

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
Premium Nervous system Spinal cord Peripheral nervous system
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

-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
