Unit 2 Exam Blueprint – Theme of Nervous System Control Lectures on cellular communication, neuronal impulse, afferent senses, CNS function and efferent control Silverthorn References – Chapters 6, 8-10 (IN-CLASS), Chapters 11 & Part 13 (CANVAS) Exam Breakdown – 60 Items, distributed over Three Levels of Challenge 30-35% on Level I Factual Knowledge; Undisputed truth, Named Processes, Definitions 40-45% on Level II Fundamental Principles, Concepts, & Theories; Themes, Laws, Relationships, Purpose, Mechanism, Sequential events, Cause/Effect, Structure/Function, Event/Time, Situation/Adaptation 20-25% on Level III Applied Problem Solving, Thinking, & Decisions; Predict Outcomes, Interpret Meaning, Calculations, Explanations, Determine Significance, Probability, Infer, Evaluate, Conclude Exam Topics Topic: Nervous System Organization (Ch. 6 & 8) ~Can you order the increasing complexity of nervous anatomy and physiology? (hint: which is more complex a nervous circuit or a pathway?) Topic: Neuron Physiology (Ch. 5 & 8) ~Can you order the procedural steps of neuron physiology? (i.e. stimulation through synaptic relay) ~Know the types of graded potentials and why is this known as transduction? ~Know the types of ionic channels in the dendritic, axonic, & synaptic terminals ~Know the names of and actions of neurotransmitters, each neurotransmitter’s receptor class, where to find the neurotransmitter, and how drugs and disease help to understand a neurotransmitter’s function. ~Relate neurotransmitters to neuropathies and drugs discussed in class Topic: Afferent Nervous Physiology ~For each sense, Know the Stimulus type & location, Sensory Organ & Transduction Mechanism, Relay Routing, CNS interpretive Center, and what the information is mostly used for. Examples: ~Gustation: Stimulus type and location-chemical stimuli; salt(Na+), Sweet (Glucose or other hexose sugar), Bitter (toxins), sour (acid), umami (monosodium glutamate) located in 3 types of gustatory hair cells in taste buds on tongue. Type 1: detects Na+, cleans taste pore of excess K+ and N.T. Type 2: sweet, umami, and bitter. Type 3: sour-only true pre-synaptic. Sensory Organ: Tongue. Transduction Mechanism: In the  gustatory system , our perception of five primary  taste  qualities  (sweet, salty, sour, bitter and umami [savoriness] ) depends on taste  transduction pathways, through taste receptor cells, G proteins, ion channels, and  effector enzymes.” (Wikipedia). Relay Routing: The front of tongue CN9, Further back CN7, Very back CN10. Relayed into medulla- nucleus solitaries area that activates gag and vomit reflexes. Sent from medulla to gustatory readers in insula-long term affects on memory. Alerts and stimulates ANS that food is on the way. Gets hormones ready and helps us swallow, and flavor. Tongue also has sterognosis.
