Control Systems Nervous Reflexes – Connecting afferent and efferent pathways Silverthorn Reading – Ch. 9 - 12 Learning Objectives 9 –12.1. Identify and Explain the Properties of Receptor Potential, Signal Transduction, Receptive Fields, Lateral Inhibition and Labeled Lines as they apply to understanding the afferent sensory pathways 9 – 12.2 Associate each Sense with the correct Afferent division (Somatic, Visceral and Special Senses) and order the events for each Sense as to stimulus – detection anatomy – transduction mechanism – labeled line routing and anatomical CNS processor 9 – 12.3 Explain Higher CNS processing of Consciousness, Memory and Learning, Behavior, and Language and apply how sensory information is influential 9 – 12.4 Describe the divisions of the autonomic motor system by each division’s purpose, relay, targets and adjusted physiology. 9 - 12.5 Describe the planning, initiation, relay and excitation events of the somatic motor division. Key Terms: Visceral Sensory, Somatic Sensory, Receptor Transduction, Nerve Energy, Labeled Line, First order, Second order, Third order, Receptor Field, Lateral inhibition, Noxious, Pain, Perception, Conscious and subconscious, Photon, Olfaction, Gustation, Hair cell, Stereocilia, Otolith, Visual field, Odorant, Visual and Sound energy, organ of corti, mitral cell, basal cell, Bipolar cell, Ganglion cell, Population coding, Frequency coding, Discrimination, Sensitivity, Topography. Accommodation, Reflection, Refraction, Tract, Association Area, Nuclei, Grey matter, White Matter, Blood-Brain Barrier, Cerebrum, Diencephalon, Brain Stem, Spinal Cord, Meninges, Doral horn, Ventral Horn, Lobe, Enlargement, Spinal Nerve, Ascending/Descending Tract, Cortex, Memory, Arousal, Plasticity, Memory, Learning, Behavior, sympathetic division, parasympathetic division, preganglionic, postganglionic, adnergic signal, cholinergic signal, fight or flight physiology, rest and replenish phsyiology, somatic motor division, motor plan, motor memory, motor activation and relay, muscle excitation I. Overview of concepts and KEY questions asked of a Nervous Reflex’s Physiology A. Sensory Detection What can be detected? How does it produce a graded potential? When is recognized? How much stimuli must be present? B. Afferent Relay What division does the labeled line belong to? Where does it terminate? How does the line discriminate Acuity from Intensity? C. CNS processing What anatomy processes specific information? What are association areas? Which information is conscious or subconscious? How is the information useful? When is the information stored for later purposes? How is the information linked to controlling body movements? D. Autonomic or Somatic Motor activation
