PPT-Synapses and Neurotransmitters

HCS 2050 SLO 166 Describing impulse transmission at the synapse including the function of several neurotransmitters and the role of cellular receptors in the action of neurotransmission Synapse. IMPULSES SYNAPSES AND CIRCUITS A large part of neuroscience concerns the nut s and bolts of the s ubject how single cells work and how information is conveyed from cell to cell across synapses It should be obviou Synapses are a fundamental part of neural pathways as they regulate decision-making in terms of exciting or inhibiting the post-synaptic neurons. . Review: . Action potentials (AP) reach terminal bud of the pre-synaptic neuron. . Neurons . do. not . undergo mitosis!. The . Nervous System can transmit impulses as fast as 100 meters per . second!. If . we lined up all the neurons in our body it would be around 600 miles . long!. Chapter 48. YOU MUST KNOW. The anatomy of a neuron. . The role of active transport in establishing the membrane potential of a neuron. . How long-distance and short-distance signaling is done in neurons. . Nervous system. Dr. . Makarchuk. . Iryna. The nervous system enables the body to respond to continuous changes in its external and internal environment. It controls and integrates the functional activities of the organs and organ systems. . The cells of the nervous system and neurotransmitters at . synapses. (a) Structure and function of neurones. (c) Function of converging, diverging and reverberating pathways. NS cells and neurotransmitters at synapses. Ms. . Carmelitano. Introduction. Neurons are the building blocks of behavior. The 10 to 100 billion neurons make about 13 trillion connections with each other over the synapses. Essential Question: How do messages cross the synapses?. Spinal cord. Transmits messages from the brain to the other areas of the body.. Efferent – away from the brain out to the body. Produces muscle action. Afferent – from the periphery to the brain. Section 1 – Functions & Divisions of the Nervous System (pp. 386-387). This is your brain…. The Nervous System. And this is your brain – IN ANATOMY!!. Or better yet…. The Nervous System. Functions of the Nervous System. substances that are manufactured in the brain, . spinal cord, glands and other parts of the body that may act as neurotransmitters. . Excitatory effects & . Inhibitory . effects.  Excitatory neurotransmitters trigger a nerve impulses in the receiving cell (they speed up neuron communication) while inhibitory neurotransmitters act to prevent further transmission of an impulse.(they slow down neural communication) . Brain and Behavior. David Eagleman. Jonathan . Downar. Chapter Outline. The Cells of the Brain. Synaptic Transmission: Chemical Signaling in the Brain. Spikes: Electrical Signaling in the Brain. What Do Spikes Mean? The Neural Code. neurotransmitter . is a chemical compound that transmits an impulse from a nerve cell to a target cell. Target cells may be another nerve cell, a muscle cell, or a gland cell.. Learning Goal . Describe the role of amines as neurotransmitters.. How to get to the different . campus?. Information transfer between universities . Seminar online . Courses online . Social life in the university . Different sports. Cultural activities. Hybrid system . Key . Area . 4. Learning Intentions. Describe the structures and functions neurons. . Name the different types of neurons. . D. escribe the structure and function of the myelin sheath.. Explain how nerve impulses are transmitted between neurons..
