Chapter 4 Neurons, Hormones, And The Brain - 1699 Words

Patrick Beninga Professor Hanretty PSY 202 Section 16 7 October 2015 Chapter 4: Neurons, Hormones, and the Brain The Nervous System: A Basic Blueprint The Central Nervous System Central Nervous System The par of the nervous system consisting of the brain and the spinal cord interprets information about the senses ex: Touch, Taste, Sound, Smell. Spinal Cord A collection of neurons and supportive tissue running from the base of the brain down the center of the back, protected by a column of bones (the spinal column) acts as a bridge between the brain and the rest of the body spinal reflexes are subconscious Because the brain and spinal cord are connected, reflexes can be influenced by thoughts and emotions example: increased heart rate when nervous Peripheral Nervous System Peripheral Nervous System All portions of the nervous system outside the brain and spinal cord; it includes sensory and motor nerves Sensory Nerves Carry messages from special receptors in the skin, muscles, and other internal and external sense organs to the spinal cord, which sends them to the brain Motor Nerves Carry orders from the central nervous system to muscles, glands, and internal organs Somatic Nervous System the subdivision of the peripheral nervous system that connects to sensory receptors and to skeletal muscles; sometimes called the skeletal nervous system Autonomic nervous system The subdivision of the peripheral nervous system that regulates the internal organs and glands SympatheticShow MoreRelatedMajor Divisions Of The Nervous System1514 Words   |  7 Pagesincludes the brain and spinal cord, the CNS processes information and send commands to the body. †¢ PNS - sensory (afferent nerves) senses stimulus inside and outside the body and send information about the stimulus to the CNS. The motor (efferent nerves) carry information from the CNS to the body’s systems. †¢ Autonomic (involuntary to visceral organs) and somatic (voluntary to skeletal muscle) Sympathetic and parasympathetic. 2. Name the different anatomical parts of a neuron and discussRead MoreIs Our Identity Of The Heart?1382 Words   |  6 PagesPsych Chapter Dos Is our identity in the heart? In the brain? In the whole body? Biological Psychologists explore the associations between body, mind, and behavior. Cell Body- The cell’s life- support center Dendrites- Receive messages from other cells Axon- passes messages away from the cell body to other neurons, muscles, or glands Neutral Impulse- (actin potential) electrical signal traveling down the axon Myelin Sheath- covers the axon of some neurons and helps speed neutral impulses TerminalRead MoreBiological Bases Of Mental Life And Behavior861 Words   |  4 PagesLearning objectives Set Reading: Chapter 3. Biological bases of mental life and behaviour Task A. Answer the following five learning objectives [maximum 100 words per objective] 1. Explain the structure of neurons. How do neurons communicate with each other? How does the Endocrine system communicate? A neuron consists of a cell body, axon and dendrites. The cell body has a neuron, which is the control centre that controls and regulates the activities of the neuron. The dendrites are extending inRead MoreLearning : Grow Your Brain Cells1202 Words   |  5 PagesLearning: Grow Your Brain Cells In the book Spark, written by Dr. John J. Ratey, he discusses how exercise can positively affect how your brain works. He provides studies and personal experiences to support the claims he makes. I always knew exercise would improve your life but never could have imagined how much it can affect your brain health as well. The chapter I thought spoke the most to me was chapter two, Learning: Grow Your Brain Cells. The chapter starts out by mentions Naperville, whichRead MoreInfluence on Behavior1104 Words   |  5 Pagesdealing with the nervious actions and the sensese mechanism. Evolutionary Evolutionary psychology is a relatively new discipline that applies the principles of Darwinian natural selection to the study of the human mind. A central claim is that the brain evolved to solve problems encountered by our hunter gatherer ancestors during the upper Pleistocene period over 10000 years ago, a time know as the Environment of Evolutionary Adaptation.

What are the two main functions of the sympathetic nervous system? (A) Activating system that arouses the body, mobilizing its energy in stressful situations – fight/flight (B) Regulates strong emotional reactions 2. What are the two main functions of the parasympathetic NS? â€Å"Rest and Digest,† Calming system that conserves energy. 3. How do the sympathetic and parasympathetic nervous systems work together (what are some images and metaphors used to describe them)?

Compare and contrast the Information Processing Approach, the Parallel Distributed Processing Model, the Levels of Processing Model, and the Traditional Three-stage Memory Model. Information Processing Approach- states that memory is a process, analogous to a computer, where information goes through three basic processes-encoding, storage, and retrieval Parallel Distributed Processing Model- states memory is distributed across a wide network of interconnected neuronsRead MoreHow Neurons Communicate With Each Other Through Electrical And Chemical Processes1845 Words   |  8 PagesDescribe how neurons communicate with each other through electrical and chemical processes. Neurons communicate with each other through an electrochemical process in three steps (Stufflebeam, 2008). An electrical impulse will travel down the axon to axon terminals. This causes the vesicles to open and neurotransmitter molecules are released into the synaptic gap. Neurotransmitter molecules then cross the synaptic gap and enters the receptor sites located on the dendrites of the receiving neuron. The informationRead MoreThe Central Nervous System14042 Words   |  57 PagesOur 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. We will see that the body is controlled by an informationRead Moreanatomy 11.21575 Words   |  7 PagesStudy chapter objectives, summaries, and reviews Review your lecture notes ANS Define: denervation hypersensitivity, ganglia, mass activation, sympathoadrenal system, dual innervation. What are the two divisions of the ANS? Where are the neurons for each division located, and what is the major function of each division? What type of neurons (sensory or motor) are in the ANS? What are the names for the two neurons in the ANS system? What size fibers make up the preganglionic neurons? The
