Nervous System Exam Study Guide YOURSELF Nervous System Exam Study Guide Nervous System Exam Sections: Multiple Choice (<100 Q) - Weds, May 23 Matching Structures with Functions & Numbering Steps of Action Potentials & Steps of Synaptic Transmission– Fri, May 25 Labeling diagrams & photos – Fri, May 25 Sheep Brain Practical Exam – Baaah, Humbug! (in other words, we’re skipping it)

Nervous System Exam Journal Due Fri., May 25 We will skip the remaining questions from the DVD – just the five we did in class. Checklist of journal assignments: Table of Contents Word of the Day Nervous Title Page Neuron Diagram Structural & Functional Organization of the Nervous System Human Brain Diagrams Spinal Cord Diagram & Reflex Arc Description Brain Structures & Functions Matching Neurophysiology Sheep Brain Diagrams Sheep Brain Photos (new on website) Synaptic Transmission Neurophysiology DVD questions #1-5 Neuropharmacology Make a new title page for our final unit: “The Viscera” New Journal Assignments for our final unit will be added each day! They need to be printed out IN COLOR and labeled

Label Major Brain Regions Views include lateral, inferior, mid-sagittal, transverse, & coronal using photos instead of diagrams Forebrain = Cerebral Cortex, Basal Ganglia1, Limbic System2, Corpus Callosum, Lateral Ventricles Midbrain = Thalamus, Hypothalamus, Colliculi, 3rd Ventricle, Pineal, Pituitary Hindbrain = Pons, Medulla, Peduncles, Cerebellum, 4th Ventricle 1Includes Caudate Nucleus, Putamen, Corpus Striatum, and more 2Includes Hippocampus, Fornix, and more “Brainstem” is a generalized term which is often limited to the hindbrain, but sometimes includes the midbrain.

A difficult view… Transverse Section, Looking down on top of head, eyes upward Hint for #1: Bridge between right and left sides of forebrain. The true “Information Superhighway!” 1 Yep, this arches over everything and connects with #1 at the top 2 3 5 6 4 Don’t try to label all these lines! Only label the red lines on the other side! Hint for #2, 3, & 4: Major parts of the basal ganglia Hint for #5: Named after cute sea creatures Hint for #6: Fluid-filled cavity on left & right sides of brain

Other Diagrams on Exam Neuron (dendrites, soma, axon, nucleus, axon hillock, axon terminal, myelin sheath, nodes of Ranvier, axon collateral, synapse) Action Potential Graph (label values, resting potential, EPSP, IPSP, sub-threshold stimulus, threshold, temporal summation, spatial summation, depolarization, peak, repolarization, hyperpolarization, overshoot) Synapse (pre- and post-synaptic cells, synaptic cleft, synaptic vesicles, AP, neurotransmitter, receptor, neurotransmitter deactivation enzyme, chemical gate)

PS : # 5 & 6 are interchangeable Putting Neurophysiological Events in Order (Part I) – TRY it for Practice NOW! 2 Voltage-gated sodium channels open. The membrane potential is repolarized. An excitatory stimulus depolarizes the axon hillock above the threshold. Voltage-gated potassium channels open. Sodium ions rush into the cell. Potassium ions flow out of the cell. Time-sensitive gates deactivate the sodium channels. The membrane potential is rapidly depolarized.   These events describe _____________________________________. 8 1 Please THINK for 3 minutes before clicking for the answers… 6 3 7 5 4 an Action Potential PS : # 5 & 6 are interchangeable

Synaptic Transmission Putting Neurophysiological Events in Order (Part II) – TRY it for Practice NOW! 4 Synaptic vesicles fuse with the cell membrane. Neurotransmitter diffuses across the synaptic cleft. Chemical gates open and change the membrane potential. Neurotransmitter binds with receptor molecules. Voltage-gated calcium channels open. An action potential arrives at the axon terminal. Calcium ions enter the cell. Neurotransmitter is released into the synaptic cleft.   These events describe _____________________________________. 6 8 Please THINK for 3 minutes before clicking for the answers… 7 2 1 3 5 Synaptic Transmission

Homunculus: Distorted map of body on somatosensory and motor cortex Homunculus: Distorted map of body on somatosensory and motor cortex. Larger body parts indicate that more neurons are dedicated to that body part.
