Term
WHAT ARE THE 7 MAJOR DIVISIONS OF THE CNS?
Definition
CEREBRAL HEMISPHERES, DIENCEPHALON, CEREBELLUM, [MIDBRAIN, PONS, AND MEDULLA WHICH CONSISTS OF THE BRAIN STEM] AND SPINAL CORD
Term
WHAT IS THE LARGEST DIVISION OF THE HUMAN BRAIN?
Definition
THE CEREBRUM.
Term
HOW MANY HEMISPHERES IS THE CEREBRUM COMPRISED OF?
Definition
2 HEMISPHERES
Term
WHAT ARE THE 2 HEMISPHERES OF THE CEREBRUM CONNECTED BY?
Definition
CORPUS CALLOSUM. THE CORPUS CALLOSUM FACILITATES INTERHEMISPHERIC COMMUNICATION.
Term
WHAT 3 PARTS ARE FROM THE CEREBRUM?
Definition
CORTEX, WHITE MATTER, AND BASAL GANGLIA
Term
LIST THE DIVISIONS OF THE CORTEX.
Definition
FRONTAL, PARIETAL, OCCIPITAL, AND TEMPORAL.
Term
WHAT IS THE CORTEX RESPONSIBLE FOR? (6 ANSWERS)
Definition
THE CORTEX IS RESPONSIBLE FOR HIGH LEVEL THOUGH PROCESS, SENSORY PERCEPTION, PLANNING MOTOR FUNCTIONS, ABSTRACT REASONING, COGNITION AND LANGUAGE.
Term
WHAT IS INCLUDED IN THE CEREBRAL WHITE MATTER AND WHAT DOES IT DO?
Definition
THE CEREBRAL WHITE MATTER INCLUDES THE CORPUS CALLOSUM WHICH CONNECTS THE HEMISPHERES. THE WHITE MATTER TRANSMITS SIGNALS TO OTHER PARTS OF THE CORTEX OR OTHER PARTS OF THE CNS.
Term
WHAT TYPE OF MATTER IS THE BASAL GANGLIA AND WHERE IS IT AT?
Definition
IT IS GRAY MATTER. LOCATED DEEP IN THE CEREBRUM.
Term
WHAT IS THE BASAL GANGLIA RESPONSIBLE FOR?
Definition
COORDINATING MOVEMENT AND INHIBITING UNWANTED MOVEMENT
Term
WHAT TYPE OF RECEPTORS ARE OF LARGE CONCENTRATION IN THE BASAL GANGLIA?
Definition
DOPAMINERGIC RECEPTORS
Term
THE DOPAMINERGIC RECEPTORS ON THE BASAL GANGLIA CAN BE AFFECTED BY WHAT DRUG? WHAT TYPE OF AFFECTS DOES IT CAUSE?
Definition
REGLAN. IT CAN CAUSE EXTRAPYRAMIDAL SIDE EFFECTS.
Term
THE BASAL GANGLIA CONSISTS OF 4 DIFFERENT TYPES OF NUCLEI. WHAT ARE THEY?
Definition
THE CAUDATE AND PUTAMEN WHICH ARE BOTH STRIATUM ALONG WITH THE GLOBUS PALLIDUS AND SUBSTANTIA NIGRA.
Term
WHERE IS THE LIMBIC SYSTEM LOCATED?
Definition
IT IS THE "RIM" AROUND THE CORTEX
Term
WHAT ARE THE FUNCTIONS OF THE LIMBIC SYSTEM? (5 ANSWERS)
Definition
PRIMARY FUNCTIONS INCLUDES: REWARD, SOCIAL BEHAVIOR, ROGUE MEMORY, EMOTION, AND SOME PAIN/AUTONOMIC FUNCTIONS
Term
WHAT THREE PARTS DOES THE LIMBIC SYSTEM CONSIST OF?
Definition
CINGULATE GYRUS, HIPPOCAMPUS, AMYGDALA
Term
WHAT DOES THE HIPPOCAMPUS DO?
Definition
ESSENTIAL TO MEMORY FORMATION AND RETRIEVAL
Term
WHERE IS THE CINGULATE CYRUS LOCATED AT?
Definition
IMMEDIATELY SUPERIOR TO CORPUS CALLOSUM
Term
WHAT DOES THE AMYGDALA DO?
Definition
MEMORY CONSOLIDATION, EMOTION, AND FEAR CONDITIONING.
Term
WHAT 2 STRUCTURE DOES THE DIENCEPHALON CONTAIN?
Definition
THALMUS AND HYPOTHALMUS
Term
WHAT DOES THE THALAMUS DO?
Definition
IT IS KNOWN AS THE RELAY POINT... IT FILTERS AND REGULATES. MAINLY IT DECIDES WHAT MAKES IT TO OUR CONSCIOUS THOUGHT PROCESS
Term
WHAT IS THE HYPOTHALMUS THE MAIN SITE OF?
Definition
ANS ORGANIZATION
Term
WHAT DOES THE HYPOTHALMUS CONTROL AND REGULATE?
Definition
IT CONTROLS THE SYMPATHETIC AND PARASYMPATHETIC FUNCTION ALONG WITH HUNGER, THIRST, TEMPERATURE REGULATION, SEXUAL REFLEXES, RESPONSE TO EMOTIONAL AND PHYSICAL STRESS, ETC.. IT REGULATES SOME HORMONE PRODUCTION AND SECRETION.
Term
HOW MANY REGIONS ARE PRESENT IN THE CEREBELLUM?
Definition
3
Term
WHAT ARE THE 3 REGIONS OF THE CEREBELLUM?
Definition
CEREBELLAR VERMIS (MEDIAL), CEREBELLAR HEMISPHERES (LATERALLY), AND FLOCCULONDULAR LOBE
Term
WHAT DOES THE CEREBELLUM DO?
Definition
COORDINATE VOLUNTARY MOVEMENTS, MAINTAIN BALANCE, CONTROL EYE MOVEMENT AND HELP WITH COGNITIVE FUNCTIONS SUCH AS LANGUAGE. (ETOH INTOXICATION AFFECTS THE CEREBELLUM).
Term
WHAT DOES THE BRAINSTEM CONNECT?
Definition
THE SPINAL CORD TO THE THALMUS AND CORTEX.
Term
WHERE DOES MOST CRANIAL NERVES ARISE FROM?
Definition
THE BRAINSTEM
Term
WHAT 3 STRUCTURES DOES THE BRAINSTEM CONSIST OF?
Definition
MIDBRAIN, PONS, AND MEDULLA
Term
WHAT IS IMPORTANT ABOUT THE MIDBRAIN?
Definition
IT CONTAINS PERIAQUEDUCTAL GREY MATTER WHICH IS IMPORTANT IN PAIN PERCEPTION.
Term
WHAT DOES THE MEDULLA AND PONS REGULATE?
Definition
THE MORE ACUTE FUNCTIONS OF THE ANS.
Term
WHAT 3 CATEGORIES DOES THE MEDULLA AND PONS REGULATE?
Definition
1) RESPONSIBLE FOR MOMENT TO MOMENT HEMODYNAMIC CHANGES, 2) CONTAINS CENTERS OR RESPIRATORY CONTROL, 3)VISCERAL ORGANS ARE KEPT IN A STATE OF INTERMEDIATE TONE WHICH CAN BE AUGMENTED OR DIMINISHED BASES ON RATE OF NERVE FIRING.
Term
THE MEDULLA AND PONS CONTAINS 3 CENTERS OR RESPIRATORY CONTROL. WHAT ARE THEY AND WHAT DO THEY DO?
Definition
1) VRG VENTRAL RESPIRATORY GROUP. INSPIRATION AND EXPIRATION; INITIATION OF INSPIRATION AFTER DRG. 2) DRG DORSAL RESPIRATORY GROUP, RHYTHM AND INSPIRATION. 3) PRG PONTINE RESPIRATORY GROUP, REFLEX COUGH
Term
WHERE DOES THE SPINAL CORD TRAVEL?
Definition
FROM THE BASE OF THE BRAINSTEM TO THE LUMBAR VERTEBRAE
Term
WHAT 2 MAIN NEURONS ARE ON THE SPINAL CORD?
Definition
MOTOR AND SENSORY
Term
WHERE IS THE SENSORY AND MOTOR NEURONS LOCATED ON THE SPINAL CORD?
Definition
SENSORY NEURONS ARE ON THE DORSAL (POSTERIOR) HORNS OF GRAY MATTER. THE MOTOR NEURONS ARE ON THE VENTAL (ANTERIOR) HORNS OF GRAY MATTER.
Term
