EXAM 2 STUDY GUIDE 2 9 15 Chapter 4 Study Hints Understand the breakdown of Central CNS vs Peripheral Nervous System PNS and the sub areas for PNS including the somatic nervous system motor for voluntary muscles and sensory and the autonomic nervous system controls involuntary muscles such as the heart intestines and other organs The autonomic nervous system breaks down further into the sympathetic fight or flight and parasympathetic vegetative systems Figure 4 1 is good for reviewing this material What is the difference between grey and white matter in the spinal cord Where are each found and why What is the Bell Magendie law Need to understand dorsal ventral orientation for this Pay particular attention to the following image which might appear on the exam Figure 4 3 What do our cranial nerves do for us in general To help out some I won t require you to be able to identify I XII on an diagram but you should be able to answer general questions about the names of the cranial nerves and whether they are for sensory or motor or both The major functions of each are in Table 4 4 or you can use the table with the mnemonics I provided in my PPT Know the 3 main areas of the hindbrain medulla pons and the little brain cerebellum What are the main functions of the cerebellum The hindbrain contains the reticular formation and the raphe system Know the importance of these There are 5 areas associated with the midbrain tectum superior and inferior colliculus tegmentum and the substantia nigra What is the main function of the two colliculi Sensory processing What is the substantia nigra important for We discussed 7 subcortical regions of the forebrain Know the major function of each Limbic System Thalamus Hypothalamus Pituitary Gland Basal Ganglia consists of the caudate putamen and globus pallidus Basal Forebrain nucleus basalis and Hippocampus Example I say hippocampus you say memory etc Ventricles are cerebrospinal fluid CSF filled cavities within the CNS and meninges are membranes that surround the brain and spinal cord What are the main functions of the ventricles and meninges What are the 4 cerebral lobes and what is are the MAJOR function s of each As noted above be able to identify them on a diagram Pay particular attention to the following image which might appear on the exam Figure 4 23 Figures 4 21 and 4 22 demonstrates the column and laminae organization of the cerebral cortex It would be good to understand this organization Know the specific importance of the motor cortex and the somatosensory cortex Figure 4 24 demonstrates the homunculus little man or the organization of the motor and somatosensory cortex Know that each location in the somatosensory cortex represents sensation from a different part of the contralateral body and each location in the motor cortex regulates movement of a different part of thecontralateral body What are the important functions of the prefrontal cortex While you should read and understand Table 4 5 don t stress over it in terms of the exam We will talk about some research methods in class and it is good to know HOW we get at some of this data but you won t be asked to tell me HOW fMRI works for example but you should be able to understand what fMRI is useful for Chapter 5 Study Hints The human central nervous system begins to form when the embryo is approximately 2 weeks old and by 24 days thedorsal surface thickens forming a neural tube surrounding a fluid filled cavity the forward end enlarges and differentiates into the hindbrain midbrain and forebrain and the rest of theneural tube becomes the spinal cord What does the fluid filled cavity of the neural tube become During development the brain starts with our three regions fore mid and hind brain but quickly moves from 3 to 5 main derivatives The forebrain divides into the endbrain and pairedbrain and the hindbrain divides into the afterbrain and the medullary brain The midbrain doesn t divide Who is Roger Sperry and what famous experiment did he perform What did the results of that teach us Understand and be able to answer conceptual or factual questions about the five stages of neurons during development Proliferation Migration Differentiation Myelination Synaptogenesis What are stem cells and in what parts of the mature nervous system do we see new neurons Growing axons reach their target area by following a gradient of chemicals in which they are attracted by some chemicals and repelled by others Define neurotrophin NGF apoptosis pruning and know the interaction between neurons and these chemicals What effect and by what mechanism does alcohol affect fetal development Cocaine Nicotine What are the effects of environment on brain development Can the shape of neurons change during adulthood Neuronal readjustments synapse formation and pruning continue throughout life based on experiences and the brain can change its anatomy over time within limits this is known as plasticity Understand the concepts associated with the effects of special experiences There are several important time sensitive treatments for brain damage such as a closed head injury or a stroke Know these and how they differ from later mechanisms of recovery What is sprouting Denervation supersensitivity Spouting Denervation super sensitivity Know the reorganized sensory representations and the phantom limb
