Nervous system

Introduction The nervous system serves the purposes of communication inside of the body, coordination, movement, and sensation. The primary components that make the nervous system carry out its functions include the brain, spinal cord, nerves, and ganglia (Saladin 2011 p. 10). Each component carries out its specific function through electrical and chemicals messages (Saladin 2011 p. 352). The cerebral cortex of the brain is made up of neurons that make connections with other parts of the brain. Different

maintain homeostasis. Homeostasis is the tendency of anatomical, behavioural and physiological systems to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function. (1) A major physiological system that works in maintaining homeostasis in animals, specifically humans, is the nervous system. The nervous system consists of a vast network of interconnecting neurons which transmit electronic signals throughout

The Neuron The central nervous system is one of the most important systems in the human body, and at its core is the neuron. Neurons are cells that facilitate the transmission of electrical signals throughout the body. They allow the nervous system to act as a communication network that runs throughout the entire body. Without neurons, the brain could not tell the rest of the body what to do. Neurons come in various shapes and sizes; however, they all share the same basic structure. Additionally

when we get ready to ride a bike we just get on the bike and go, because we have done it so many times that it just comes naturally to us. Another example is watching a scary movie and putting popcorn in our mouth at the same time. Well it is our nervous system that helps us to do these simple actions because it handles information. When our phone rings there are a number of functions that go on in our brain. The first thing would be our neurons in the auditory cortex which picks up the sound of the

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

from the clinical and electrophysiological point of view. In the present study, both components of the ANS were assessed including the sympathetic and the parasympathetic nervous systems. The sympathetic nervous system was assessed by using the BP changes in response to postural changes and SSR. The parasympathetic nervous system was assessed by HR changes in response to postural changes [18]. Orthostatic stress test assesses the BP and HR changes associated postural changes in the body position

Greetings class. I am Professor Valle and today we will discuss the development of the nervous system. Before we begin with the subject, I would like to share a small clip. Please focus on the signs and symptoms seen on the clip. (At this point I will show the clip on https://www.youtube.com/watch?v=b9R4cjdCGoY, it will last no more than 3 minutes). Did you see anything wrong between the couple? If so who was it? What were some of the signs and symptoms that you noticed throughout the clip? Yes

The two divisions of the autonomic nervous system (ANS), sympathetic (SNS) and parasympathetic (PNS), function in a complementary and integrated manner to maintain homeostasis. The output of the autonomic nervous system is quick in comparison to the endocrine system functions. In most cases, these systems have opposite effects, where one initiates a physiological response and the other inhibits. The nerves of this system regulate vital internal functions which are generally performed without conscious

Introduction The nervous and endocrine systems both function to maintain the stability of the internal environment. While both systems may work together as a single Neuroendocrine system, the systems may also work alone performing communications, integration and control within the body. (Patton and Thibodeau, 2010) The endocrine system consists of eight major glands; the hypothalamus, pituitary, thyroid, adrenals, pineal body, reproductive organs and the pancreas. These glands are widely separated

a person may feel. Discussing what happens in the brain as it reacts to different chemical build ups will help us as individuals better understand our body and communicate and respond to these experiences in a healthier way. The study of the nervous system is known as Neurochemistry. It 's the practice of observing
