Unformatted text preview: AMY 10 STUDY GUIDE for EXAM 4 The fourth exam will be on the Nervous System II ( here the central nervous system and some autonomic nervous system ) and Blood. View PowerPoints Chapter 7 and Chapter 7 part II and Chapter 10. Many and the concepts for chapter 7 will be in the chapter readings and worksheets that we went over. You are responsible for the reading pages below . Also, for this exam you may bring in ONE 5 x 7 index card with notes written on both sides which may be used with exam. Chapter 7: You were tested on the First part of this chapter in Exam 3: There will be some overlap in Exam 4 as you are expected to know the Basics of CNS and PNS. Also I will test you again on neuron types. (multipolar, bipolar and unipolar) Text readings covered: Page 235 ‐262 ( stop at Nerve Plexuses), Page 270. Classification of Neurons ( again) in terms of their structure and function: are they sensory or motor or interneurons ? What about their direction? Afferent or efferent? Describe the composition of gray matter and white matter ( again) Describe the events that lead up to the generation of a nerve impulse and conduction from neuron to neuron. What are the properties of an action potential? ( i. e. ALL or Nothing) What do we mean by THRESHOLD? When on the neuron does this happen? What it the difference between Nerve Impulse and GRADED IMPULSE? What is the role of the Sodium‐Potassium Pump is the process of nerve impulses? What is a sodium ion channel? What happens during DEPOLARIZATION? What are neurotransmitters? Where are they found in the neuron? How are they released? What is their function? What is a reflex arc? Compare and contrast Somatic arc with Autonomic Arc. CNS: From what part of embryo does it develop? Know the structural anatomy of the brain: the gyri, sulci, fissures ( what are theses); How is the cerebrum separated in hemisphere? Lobes? Names and recognize lobes. Specialization of Cerebrum: Association , Sensory and Motor: Be Generally familiar with strips of sensory and motor ( how this works) ; Know the specifics areas for Broca, , Auditory, Vision, Olfactory, Language Comprehension. Know that the pathway for the cerebrum is opposite ( sensing right side of body with left side of brain and visa versa). What is the CORPUS COLLASUM? DIENCEPHALON; What is the THALAMUS? EPITHALAMUS? ( It forms part of _________) What are its two important parts? What is the HYPOTHALAMUS? Its Very important role? BRAIN STEM: Locate this on a sagittal section; Midbrain: Cerebral Aquiduct, cerebral peduncles and corpora quadrigemina PONS: , Medulla Oblongata, Reticular Formation ( Know basic functions) CEREBELLUM: Know where it is, and basic functions THE MENINGES: Know the structure ,location and function of these 3 layers. The VENTRICES: Know the flow. What flows ? Where is the fluid that flows produced? SPINAL CHORD: KNOW Basic structure of chord ( figures 7.20 and 7.21) on pgs. 255 and 256. Structure of Nerve ( figure 7.23, pg. 258). What are the cranial nerves? How many are there? Know the first 4 and the vagus (#10) only. Parasympathetic Vs. Sympathetic; know some of the differences we discussed ( see Powerpoint chart) Know Rest/Disgest….Fight or Flight. Read page in text. Chapter 10: BLOOD : Text Reading: Entire Chapter ( excluding focus on Career pages) What is the composition of blood? Role of Hemoglobin? What are formed elements Compare and contrast an embryonic and adult stem cell. What are the leukocytes? Know all types What is the ABO blood typing system? Rh factor? What is an antigen? Antibody? How are more blood cells formed when RBC count is low? ( KIDNEY influence?) What is role of oxygen in RBC count? What happens to blood when it is old? What do we need to make more blood? Organs involved in blood recycling? What are steps of HEMOSTASIS? Disorders of Hemostasis? Undesirable Clotting? Hemophilia ( we didn’t go over it look it up) What is Sickle cell Anemia? What causes this? ...
