Chapter 3 of Introduction to Psychology is titled "Neuroscience and Behavior" and contains three different modules. Module seven contains information on Neurons and how they function. Module eight contains information about the nervous system and the endocrine system‚ and it also explains how the body communicates from within. Module nine is the last module and contains information on the brain. The different parts and functions of the brain are also found in module nine. Module 7 Neurons are the

much slower speed. d) What is d? Explain what happens when an action potential reaches d. The structures labeled d are synaptic knobs. When an action potential reaches the knobs‚ they release neurotransmitters that carry the signal across the synapse. These neurotransmitters usually work by binding to receptor proteins in the membrane of the receiving neuron. This binding opens gates that allow sodium ions to enter the cell. 3. Name two ways in which the structure of a neuron

Foundations of Psychology PSY300 September 4‚ 2011 Foundations of Psychology It is just another normal day for you. You were taking a leisurely stroll through the park before you decided to rest for a minute on a bench. And that is when you notice the man sitting next to you‚ singing quietly to himself. He seemed normal at first glance‚ but you begin to notice that he looks disheveled. Hair a little frazzled‚ and clothing a bit wrinkled. At first it seems no big deal. Then you

information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters. At this juncture‚ the neuron transmitting the information/signal is referred to as the presynaptic cell‚ while the cell receiving the signal is the postsynaptic cell. Glial cells‚ or glia‚ are support cells that nourish the neurons and insulate

week 1‚ we observed the basal rate of three different worms‚ and then placed the same three worms on different concentrations of caffeine and nicotine. “Caffeine is known to act as an inhibitory neurotransmitter in the brain; it promotes sleep and suppresses aurosal‚ binding to the adenosine neurotransmitter receptor to block its inhibitory action” (CCNY lab manual‚ 2014). Before our experiment was conducted we hypothesized that increasing the concentration of caffeine will increase the pulsation rate

M2 Similarities Social Learning Theory | Biological approach | The social learning theory is reductionist as it only focuses on one side of the aspect. It focuses on how behaviour is learned through observation in which they are imitating other people’s actions and behaviour. This can be explained as Albert Bandura (1977) states behaviour is learned from the environment through the process of observational learning. Individuals that are observed are named models. In society‚ people such as children

AP Psychology Midterm Study Guide #1 Unit 1: Psychology’s History and Approaches 1.Definition of Psychology? Disciplines it is rooted in? Psychology is the science of behavior and mental process; it seeks to answer how and why we think‚ feel‚ act as we do. Psychology is rooted in philosophy and biology. 2.What is the difference between nativism and empiricism? Which ancient philosophers/early psychologist were nativist? which were empiricist? Nativism is the argument that all our skills

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

- The Cell body makes the material necessary for the neuron’s growth and maintenance. - The Axon carries information from the cell body to other cells. Neurotransmitters Neurotransmitters carry information across the synaptic gap to the next neuron by opening the channel on the receptor site‚ triggering the neuron to fire. Neurotransmitters can also inhibit neurons from firing. - GABA keeps many neurons from firing‚ this helps to control the precision of the signal being carried from one neuron

Endorphins ("endogenous morphine") are endogenous opioid peptides that function as neurotransmitters.[1] They are produced by the pituitary gland and the hypothalamus in vertebrates during exercise‚[2] excitement‚ pain‚ consumption of spicy food‚ love and orgasm‚[3][4] and they resemble the opiates in their abilities to produce analgesia and a feeling of well-being. The term implies a pharmacological activity (analogous to the activity of the corticosteroid category of biochemicals) as opposed to
