THE NERVOUS SYSTEM

BREE STUDY GUIDE

MC (QUESTIONS)Answer
WHAT TWO SYSTEMS CONTROL THE BODY FUNCTIONS BY COMMUNCATION WITH THE BILLIONS OF CELLS IN THE HUMAN BODY IN ORDER TO KEEP IT ALIVE? NERVOUS AND ENDOCRINE SYSTEM
WHEN UR SLEEPING UR BRAIN IS STILL ACTIVE..AS A WAT?? AUTOMATIC PILOT
WAT IS THE NERVOUS SYSTEM MADE UP OF? BRAIN, SPINAL CORD, NUMEROUS NERVES OF THE BODY, AND SENSORY ORGANS
WHAT R THE TWO PARTS OF THE AUTONOMIC NERVOUS SYSTEM?? SYMPATHETIC AND THE PARASYMPATHETIC NERVOUS SYSTEMS
SENSORY OF AFFERENT FUNCTION SENSES OR RECOGNIZES THE EXTERNAL CHANGES IN THE ENVIRONMENT SUCH AS COLD OR HEAT OR INTERNAL CHANGES IN THE BODY SUCH AS A DECREASE IN POTASSIUM OR CALCIUM
INTEGRATIVE (OR CNS) FUNCTION PROCESSES THE PERCEIVED INFO. ABOUT THE CHANGES AND INTERPRETS OR EXPLAINS THE CHANGES IN THE EXTERNAL AND INTERNAL ENVIROMENTS.
MOTOR OR EFFERENT FUNCTION RESPONDS TO THE AFOREMENTIONED INTERPRETATION AND INTEGRATION OF THE EXTERNAL AND INTERNAL ENVIRONMENTS BY MAKING MUSCLES MOVE, GROUPS OF MUSCLES INTERACT, AND GLANDS SECRETE HORMONES OR OTHER CHEMICALS INTO THE BLOODSTREAM
HOW MANY NEURONS IS THE BRAIN MADE UP OF?? 100 BILLION NEURONS
DENDRITES BRING INFO TO THE CELL BODY FROM THE CNS
AXONS TAKE INFO AWAY FROM THE CELL BODY TO THE CNS
THE NEURONS PRODUCE ELECTROCHEMICAL HORMONES CALLED NEUROTRANSMITTERS
SIGNALS IN NEURONS TRANSFER INFO. TO OTHER NEURONS BY CROSSING THE SYNAPSES TO CONTROL GLANDS, ORGANS, OR MUSCLES
THE NERVOUS SYSTEM USES NEURONAL CIRCUITS THROUGHOUT THE BRAIN TO STORE MEMORY AND UNDERGOES CONTINUAL MODIFICATION SO THAT A PERSON CAN.... LEARN NEW THINGS
THE BRAIN CAN ACTUALLY_______ ITSELF WHEN NECESSARY. REWIRE
THE ACTION OF THE IMPULSE THAT TRIGGERS THE RELEASE OF A NEUROTRANSMITTER TO ANOTHER NEURON IS CALLED THE.... FIRING OF NEURONS AND IS BOTH ELECTRICAL AND CHEMICAL IN NATURE
HOW MANY NEUOTRANSMITTERS IN THE THE BRAIN 50
WHAT IS THE NAME FOR THE CONSTANT EXCHANGE OR FIRING OF CHEMICAL MESSAGES BETWEEN NEURONS IS.. NEUROTRANSMISSION
NEURONS RELEASE... NEUROTRANSMITTERS
POLARIZATION OF THE AXON POSITIVELY CHARGED SODIUM IONS ENTER THE AXON, SHIFTING THE CHARGE WITHIN THE AXON FROM NEGATIVE TO POSITIVE
REUPTAKE CARRYING PROTEINS TRANSPORT THE NEURTRANSMITTERS BACK TO THE AXON FROM WHICH THEY ORGINALLY CAME
THE CENTRAL NERVOUS SYSTEM IS COMPOSED OF THE BRAIN AND SPINAL CORD
THE BRAIN WEIGHS APPROXIMATELY 2.8 TO 3 POUNDS
THE SPINAL CORD IS THE MAIN PATHWAY FOR INFO CONNECTIN THE BRAIN TO THE PERIPHERAL NERVOUS SYSTEM
THE MAIN REGIONS OF THESE NERVES ARE CALLED THE SKULL THE CERVICAL VERTEBRAE, THE THORACIC VERTEBRAE, THE LUMBAR VERTEBRAE, AND TEH SACRAL VERTEBRAE(SACRUM)
PROTECTION THE CSF PROTEXTS THE BRAIN FROM DAMAGE BY ACTING LIKE A CUSHION TO LESSEN THE IMPACT IN THE EVENT OF A BLOW TO THE HEAD.
EXCRETION OF WASTE PRODUCTS DUE TO THE ONE-WAY DIRECTION OF THE FLOW OF CSF TO THE BLOOD, IT TAKES HARMFUL METABOLITES OF DRUGS AND OTHER TOXIC SUBSTANCES AWAY FROM THE BRAIN.
ENDOCRINE COMMUNICATION CSF SERVES AS THE VEHICLE TO TRANSPORT HORMONES RELEASED INTO THE CSF CAN BE XARRIED TO REMOTE SITES OF THE BRAIN
THE HEAD OR CEPHALIC REGION OF THE BODY HAS A _______ STRUCTURE, THE SKULL, TO PROTECT THE BRAIN FROM INJURY BONY
THE BRAIN CAN BE DIVIDED DOWN THE MIDDLE, LENGHTWISE, INTO TWO HALVES CALLED THE CEREBRAL HEMISPHERES
THE FRONTAL LOBE IS CONCERNED WITH HIGHER INTELLECT OR REASONING, PROBLEM SOLVING, PARTS OF SPEECH, MOVEMENT OR MOTOR CORTEX, AND EMOTION
THE PARIETAL LOBE IS RELATED TO THE STIMULI AND PERCEPTION OF TOUCH, PRESSURE, TEMPERATURE, AND PAIN.
THE TEMPORAL LOBE IS RELATED TO PERCEPTION AND RECOGNITION OF AUDITORY STIMULI FOR HEARING AND MEMORY (INVOLVING THE HIPPOCAMPUS)
THE OCCIPITAL LOBE IS RELATED TO STIMULI PERTAININ TO VISION
THE MAIN PURPOSE OF THE CEREBELLUM ARE TO COORDINATE THE MOVEMENT OF THE BODY AND MAINTAIN EQUILIBRIUM AND BALANCE.
THE CEREBRUM IS DIVIDED INTO TWO MAIN PARTS CEREBRAL CORTEX AND CEREBRAL MEDULLA
CEREBRAL CORTEX CONTAINS GREY MATTER MADE UP OF THE NERVE CELLS KNOW AS NEURONS THAT CONTROL VOLUNTARY ACTON OF THE BODY.
CEREBRAL MEDULLA CONTAINS WHITE MATTER MADE UP OF MYELINATED AXONS OF THE NEURONS, WHICH SERVE TO CONDUCT NERVE IMPULSES TO AND FROM DIFFERENT AREAS OF THE NERVOUS SYSTEM.
THE BASAL GANGLIA REGULATES MOTOR ACTIVITY OR MOVEMENT
PARKINSON'S DISEASE DAMAGE TO THE BASAL GANGLIA MAY RESULT IN DISORDERS
THE BRAIN STEM AN EXTENSION OF THE SPINAL CORD, IS DIVIDED INTO FOR MAIN PARTS: THALAMUS, HYPOTHALAMUS, PONS, AND MEDULLA OBLONGATA
THALAMUS SITS A TEH TOP OF THE BRAIN STEM AND REGULATES AND EVALUATES THE SENSORY IMPULSES OF PAIN, HOT, COLD, AND TOUCH.
HYPOTHALAMUS LOCATED JUST BELOW THE THALAMUS, CONTROLS BODY FUNCTIONS SUCH AS WATER BALANCE, BODY TEMPERATURE, SLEEP, HUNGER AND APPETITE, SEX DRIVE, THE AUTONOMIC NERVOUS SYSTEM, AND SOME EMOTIONAL AND BEHAVIORAL RESPONSES.
PONS LOCATED BELOW THE HYOTHALAMUS, REGULATES RESPIRATION AND IS CONSIDERED THE "RELAY" STATION FOR NERVE FIBERS THAT TRAVEL TO OTHER PARTS OF THE BRAIN
MEDULLA OBLONGATA THE FINAL PART OF THE BRAIN STEM, IS LOCATED AT THE BASE OF THE BRAIN STEM AND THE TOP OF THE SPINE
RETICULAR FORMATION EXCITATORY FIBERS AND INHIBITORY
EXCITATORY FIBERS WHEN STIMULATED BY EXTERNAL STIMULI SUCH AS NOISES(TRAFFIC), BRIGHT LIGHTS, OR DANGER, THE DEGREE OF ALERTNESS IS INCREASED
INHIBITORY FIBERS AN ABSENCE OF EXTERNAL STIMULI CAUSES THE INHIBITORY FIBERS TO BECOME MOR ACTIVE, WHICH DECREASES THE ACTIVITY OF THE EXCITATORY FIBERS AND, THEREFORE, THE DEGREE OF ALERTNESS
THE FIRST ANTIPSYCHOTIC DRUG, WAS INTRODUCED IN THE 1950S CHLORPROMAZINE
THE NATIONAL INSTITUE OF MENTAL HEALTH CLASSIFIES THE FOLLOWING FOUR TYPES OF PSYCHOTHERAPEUTIC AGENTS ANTIANXIETY, ANTIDEPRESSANT, ANTIMANIC, AND ANTIPSYCHOTIC MEDICATIONS
ANXIETY IS ASSOCIATED WITH THE FOLLOWING RISK FACTORS; GENETICS, BRAIN CHEMISTRY, LIFE EVENTS, AND PERSONALITY
THERE ARE MANY FORMS OF ANXIETY, CATEGORIZED AS FOLLOWS; GENERALIZED ANXIETY DISORDER(GAD), OBSESSIVECOMPULSIVE DISORDER(OCD), PANIC DISORDER OR PANIC ATTACK, POST-TRAUMATIC STRESS DISORDER(PTSD), SOCIAL ANXIETY DISORDER(SAD), AND SPECIFIC PHOBIAS
ANXIETY CAN HIT ANYONE AT ANY TIME, BUT IS USUALLY SLOWLY PROGRESSIVE
A LACK OF SPECIFIC NEUROTRANSMITTER, GAMMA-AMINOBUTYRIC ACID(GABA) IS ASSOCIATED WITH ANXIETY
ANOTHER ANTIDEPRSSANT___________IS A POTENT INHIBITOR OF THE REUPTAKE OF BOTH SEROTONIN AND NOREPINEPHRINE EFFEXOR XR
HIGH DOSES TAKEN WITH _________ PRODUCE LETHAL EFFECTS. ALCOHOL
BENZODIAZEPINES MAY CAUSE ______________OVER LONG-TERM USE, AND ARE THEREFORE CLASSIFIED AS ________ DEPENDENCE, CLASS IV
THERE ARE MANY TYPES OF DEPRESSION, INCLUDING SEASONAL MAJOR DEPRESSION(SEASONAL AFFECTIVE DISORDER), POSTPARTUM DEPRESSION, BIPOLAR DISORDER, AND DYSTHYMIA(MILD DEPRESSION ON MOST DAYS OF THE YEAR
GENETICS PLAY AN IMPRORTANT PART IN DEPRESSION
TRAUMA AND STRESS NEGATIVE ISSUES LIKE FINANCIAL PROBLEMS, THE BREAKUP OF A RELATIONSHIP, OR THE DEATH OF A LOVED ONE CAN BRING ON DEPRESSION
PESSIMISTIC PERSONALITY LOW SELF-ESTEEM OR A NEGATIVE OUTLOOK CAN CONTRIBUTE.
PHYSICAL CONDITONS SERIOUS MEDICAL CONDITIONS OR DESEASES SUCH AS CANCER, HIV, HEART DISEASE, AND UNWANTED STERILITY CAN CONTIRBUTE TO DEPRESSION, PARTLY B/C OF THE PHYSICAL WEAKNESS AND STRESS THEY BRING ON
OTHER PSYCHOLOGICAL DISORDERS ANXIETY DISORDERS; SCHIZOPHRENIA; ANOREXIA, BULIMIA, OR COMPULSIVE EATIN DISORDERS
THE BLUES ARE COSIDERED TRANSIENT AND SHORT-TERM, WHILE DEPRESSION IS A PROLONGED CONDITION LASTING LONGER THAN TWO WEEKS AND INTERFERING WITH OR INTERRUPTING A PERSON'S LIFE AND ABILITY TO CARRY OUT DAILY TASKS AND TO ENJOY ACTIVITIES THAT PREVIOUSLY BROUGHT PLEAS
