| Question | Answer |
|---|---|
| IN WHAT STRUCTURE OF THE BRAIN DO THE NERVSES CROSS | THE PONS |
| SENSORY NEURONS | SENSE INTERNAL & EXTERAL ENVIRONMENTAL INFLUENCES & CARRIES THE MESSAGE TO THE BRAIN. |
| MOTOR NEURONS | CARRIE RESPONSES BACK TO THE PART OF THE BODY THAT HAS TO REACT. |
| THREE MEMBRAINS THAT SERVE AS PROTECTIVE COVERINGS OF THE BRAIN AND SPINAL CORD. | DURA MATER; ARACHNOID MATER; PIA MATER |
| DURA MATER | TOUGH AND THICK OUTERMOST MEMBRANE OF THE BRAIN AND SPINAL CORD. |
| ARACHNOID MATER | THE MIDDLE PROTECTIVE MEMBRANE |
| PIA MATER | THE INNER PROTECTIVE MEMBRANES |
| DIFFERENTIATE BETWEEN THE SENSORY & MOTOR NEURONS. | SENSORY -SENSES AND CARRIES THE MESSAGE TO THE BRAIN AND THE MOTOR CARRIES RESPONSES BACK TO THE PART OF THE BODY THAT NEEDS TO REACT. |
| NAME THE NAME & NUMBER OF THE SPINAL NERVES IN ORDER FROM SUPERIOR TO INFERIOR. | 1. 8 PAIR OF CERVICAL;12 PAIR OF THORACIC;5 PAIR OF LUMBAR; 5 PAIR OF SACRAL;1 COCCYGEAL |
| THE CEREBRUM SORROUNDS THE __________________ | CEREBRAL CORTEX |
| CELL BODY | THE PART OF A NEURON CONTAINING ORGANELLES |
| AXON | THE PART OF A NEURON THAT TRANSMITS IMPULSES; SOME HAVE A FATTY MYELIN SHEATH. |
| DENDRITES | THE PART OF A NEURON THAT LOOKS LIKE BRANCHES OF A TREE; RESPONSIBLE FOR RECEIVING INFORMATION FROM THE INTERNAL & EXTERNAL ENVIRONMENTS & TRANSMITTING IT TO THE CELL BODY. |
| MYELIN SHEATH | MYELINATED AXONS |
| CEREBRAL CORTEX | GRAY MATER COVERING THE CEREBRUM |
| NEUROGLIA | PROTECTS THE NERVOUS SYSTEM; THEY ENGULF UNWANTED SUBTANCES |
| LONGITUDINAL FISSURE | DIVIDES THE CEREBRUM INTO RIGHT & LEFT HEMISPHERES |
| THALAMUS | ACTS AS A RELAY STATION FOR INCOMING SENSORY STIMULI |
| NEUROGLIA | PROVIDE PROTECTION & NUTRIENTS BY ATTACHING BLOOD VESSELS TO NEURONS. |
| HYPOTHALAMAS | MAINTAINS HOMEOSTATASIS OF APPETIE, THRIST,AND TEMPERATURE |
| NERVE PAIN | NEURALGIA |
| A SPECIALIST IN THE STUDY OF THE NERVOUS SYSTEM AND IT'S DISEASES | NEURALOGIST |
| NERVE DESTRUCTION | NEUROLYSIS |
| INFLAMMATION OF MANY NERVES | POLYNEURITIS |
| RECORD OF THE ELECTRICAL ACTIVITY OF THE BRAIN | ELECTROENCEPHALOGRAM |
| HERNIA OF THE MEANINGES | MENINGOCELE |
| HERNIA OF THE SPINAL CORD AND MENINGES | MYELOMENINGOCELE |
| LOSS OF SENSATION | ANESTHESIA |
| DECREASED SENSATION | HYPOESTHESIA |
| INCREASED SENSATION | HYPERESTHESIA |
| IRRITATING SENSATION IN RESPONSE TO NORMAL STIMULI | DYESESTHESIA |
| ABNORMAL SENSATION SUCH AS NUMBNESS AND TINGLING | PARESTHESIA |
| PARALYSIS OF LIKE EXTREMITIES ON BOTH SIDES OF THE BODY | DIPLEGIA |
| PARALYSIS OF ONE EXTREMITY | MONOPLEGIA |
| PARALYSIS OF THE RIGHT HALF OR THE LEFT HALF OF THE BODY | HEMIPLEGIA |
| PARAPLEGIA | PARALYSIS OF THE LOWER PART OF THE BODY AND LEGS |
| PARALYSIS OF ALL FOUR LIMBS | QUADRIPLEGIA |
| ENCEPHALITIS | INFLAMMATION OF THE BRAIN |
| SOFTENING OF THE BRAIN | ENCEPHALOMALACIA |
| ANY DISEASE OF THE BRAIN | ENCEPHALOPATHY |
| CEREBELLUM | UNDER THE OCCIPITAL LOBE;PROTRUDES DORSALLY;IMPORTANT IN MAINTAINING BALANCE,MUSCLE COORDINATION & EQUILIBRIUM. |
| GYRI (JIGH-rye) OR CONVOLUTIONS | ON THE SURFACE OF THE CEREBRUM HAS THE APPEARENCE OF LITTLE GRAY BULGES THAT LOOK LIKE SAUSAGES. |
| FISSURES | DEEP GROVES |
| SULCI (SUL-sigh) | SHALLOW GROVES |
| THE LOBES ARE DIVIDED BY | FISSURES |
| LOBES ARE NAMED AFTER | BONES OF THE SKULL |
| THE 4 LOBES OF THE CEREBRUM ARE | FRONTAL;PARIETAL;TEMPORAL; AND OCCIPITAL |
| THE BRAIN CONSISTS OF : | 1. CEREBRUM 2. THALAMUS 3. HYPOTHALAMUS 4. BRAIN STEM 5. CEREBELLUM |
| CEREBRUM | LARGEST PART OF THE BRAIN; COVERED BY THE CEREBRAL CORTEX, WHICH IS DIVIDED INTO RIGHT AND LEFT HEMISPHERES BY THE LONGITUDINAL FISSURES BUT JOINED BY THE CORPUS CALLOSUM |
| THALAMUS | A RELAY STATION FOR SENSORY & MOTOR IMPULSES |
| HYPOTHALAMUS | HELPS REGULATE APPETITE,THIRST,EMOTIONS,& BASIC BEHAVIOR PATTERNS |
| BRAIN STEM | MIDBRAIN, PONS, MEDULLA OBLONGATA; INVOLVED WITH VISUAL & AUDITORY REFLEXES, RESPIRATION, HEART RATE, BLOOD PRESSURE & AROUSAL |
| CEREBELLUM | INVOLVED WITH MAINTAINIING BALANCE,MUSCLE COORDINATION & EQUILIBRIUM |
| THE CEREBRUM IS COVERED BY THE | CEREBRAL CORTEX |
| THE CEREBRUM ISA DIVIDED INTO RIGHT & LEFT HEMISPHERES BY THE | LONGITUDINAL FISSURES |
| WHAT JOINS THE LEFT AND RIGHT HEMISPHERES OF THE CEREBRUM | THE CORPUS CALLOSUM |
| THE SPINAL CORD STARTS AT THE | MEDULLA OBLONGATA |
| THE SPINAL CORD ENDS AT THE | CONUS MEDULLARIS |
| CAUDA EQUINA (KAW-daH ee-KWI-nah) | LOOKS LIKE A HORSE'S TAIL; |
| THE CNS IS PROTECTED BY 4 THINGS: | BONE;MENINGES,CSF,AND BBB. |
| IN THE PNS THERE ARE | 12 PAIRS OF CRANIAL NERVES & 31 PAIR OF SPINAL NERVES |
| THE NERVOUS SYSTEM HAS THREE FUNCTIONS | 1. SENSORY 2. INTEGRATIVE 3. MOTOR |
| THE CNS CONSIST OF | SPINAL CORD & BRAIN |
| THE PNS CONISTS OF THE | SENSORY AND MOTOR NERVES |
| NEURONS ARE THE CELLS THAT MAKE UP | NERVES |
| SYNAPSE (SIN-apps) | A JUNCTION AREA BETWEEN THE NEURON AND ANOTHER NEURON OR MUSCLE |
| NEUROTRANSMITTER (NEW-ROH-TRANS-MIT-ER) | A CHEMICAL RELEASED FROM A LITTLE SAC AT THE END OF THE NERVE. |
| THE NEUROTRANSMITTER TRAVELS ACROSS THE SYNAPSE AND ACTS ON THE MUSCLE, CAUSING IT TO GENERATE IT'S OWN ELECTRICAL IMPULSE THAT PRODUCES: | MUSCLE MOVEMENT |
