CRNA:Neuroanatomy
Test 2 Physiology - Neuro -Terms & Concepts - for Test 2
| Question | Answer |
|---|---|
| *Type and location of unipolar neuron | sensory, in the PNS |
| *Bipolar neuron used in this AND WHERE ARE THEY LOCATED | special senses - vision, hearing, smell, and vestibule, in the PNS |
| Multipolar neuron (rare, average, greastest) | Greatest,most abundant neurons |
| Myelin Sheath found | around CNS and PNS axons |
| Myelin Sheath and the basement membrane produce by... | schwann cells |
| Myelin increases... | the speed of conduction down an axon |
| THE MOST COMMON CHEMICAL SYNAPSE | AXODENDRITIC |
| THE JUNCTION BETWEEN AN AXON AND SOMA (THE BODY) | AXOMSOMATIC |
| THIS IS WHERE THE MYELIN IS SEGMENTED | NODES OF RANVIER |
| NAME OF THE AXON TERMINAL | BOUTON |
| *NAME OF AXON ENLARGEMENT THAT STORES & RELEASES NEUROTRANSMITTER | VARICOSITY |
| THE MOST COMMON NEUROTRANMITTER | ACETYLCHOLINE |
| ACETYLCHOLINE IS RELEASED BY ...(3) | THE PRE AND POST SYNAPTIC PARASYMPATHETIC FIBERS AND PRESYNAPTIC SYMPATHETIC FIBERS |
| THIS ENZYME THAT BREAKS DOWN ACH | CHOLINESTERASE |
| *THE NEUROTRANSMITTER THAT THE POSTSYNAPTIC SYMPHATHETIC FIBERS SECRETE | NOREPI |
| *THIS ENZYME BREAKS DOWN NOREPI | MONOAMINE OXIDASE |
| THE SUPPORTIVE TISSUE THAT BRINGS NUTRIENTS IN/WASTE OUT | SATELLITE CELLS |
| THIS PHAGOCYTIZES DEGENERATED AXONS, PRODUCES MYELIN & BASEMENT MEMBRANE | SCHWANN CELLS |
| THIS TISSUE IS AROUND PNS NERVES ONLY | MYELINATION CONNECTIVE TISSUE |
| ENDONEURIUM IS FOUND AROUND... | 1 NEURON |
| PERINEURIUM IS FOUND AROUND... | AROUND A FASCICULUS |
| These are wavy for stretch. | PERINEURIUM & ENDONEURIUM |
| *NEUROLEMMA =BASEMENT MEMBRANE =ENDONEURIUM AND IT IS FOUND WHERE | IN PNS ONLY |
| DEFINE NERVE FASCICLES | BUNDLE OF NERVES |
| PURPOSE OF THE BLOOD-BRAIN BARRIER (2) | 1)PROTECT THE BRAIN CELLS 2)PREVENTS LARGE MOLECULES FROM PASSING INTO A NEURON |
| 3 SUPPORTIVE CELLS OF THE CNS | 1) ASTROCYTE 2)OLIGODENDROCYTE 3)MICROGLIA |
| THE DEVELOPMENT OF THE NEURAL PLATE OCCURS | BY THE 3RD WEEK |
| *NEURAL TUBE BECOMES... | THE CNS |
| *NEURAL CREST BECOMES... | THE PNS |
| NERVE IN THE PNS ARE CALLED ____ IN THE CNS, BOTH ARE ____. | TRACT. BOTH ARE MYELINATED. |
| GANGLIA IN THE PNS ARE CALLED ____ IN THE CNS | NUCLEUS |
| TRACT IN THE CNS ARE CALLED ____ IN THE PNS | NERVE |
| NUCLEI IN THE CNS ARE CALLED ____ IN THE PNS | GROUP OF CELL BODIES SERVE FOR A SPECIFIC FUNCTION |
| FRONTAL LOBE IS INVOLVED WITH... | MOTOR |
| PATIETAL LOBE IS INVOLVED WITH... | SENSORY |
| TEMPORAL LOBE IS INVOLVED WITH... | HEARING |
| OCCIPITAL LOBE IS INVOLVED WITH... | VISION |
| THE LIMBIC SYSTEM IS INVOLVED WITH... | EMOTIONS AND MEMORY |
| INSULA IS LOBE IS INVOLVED WITH... | SOMATIC AND VISCERAL FUNCTIONS |
| LOCATION AND PURPOSE OF BROCA'S AREA | ANTERIOR DOMINANT LEFT HEMISPHERESPEECH AND EXPRESSIVE LANGUAGE |
| DAMAGE TO BROCA'S AREA | EXPRESSIVE APHRASIA |
| DEFINE EXPRESSIVE APHASIA | THEY DO UNDERSTAND BUT THEY CAN'T SPEAK OR WRITE |
| LOCATION AND PURPOSE OF WERNICKE'S AREA | POSTERIOR DOMINANT LEFT HEMISPHERE, UNDERSTANDING |
| GANGLION IN THE PNS ARE CALLED ____ IN THE CNS | NUCLEUS |
| DAMAGE TO THE WERNICKE'S AREA | RECEPTIVE APHASIA |
| DEFINE RECEPTIVE APHASIA | THEY CAN'T SPEAK SENSIBLY NOR WRITE BECAUSE THEY DO NOT UNDERSTAND/COMPREHEND |
| SUBCORTICAL WHITE MATTER LOCATION/TYPE | FIBER BUNDLES UNDER THE GRAY MATTER IN THE CORTEX |
| TYPE/PURPOSE OF THE INTERNAL CAPSULE | GROUPS OF SENSORY AND MOTOR WHITE MATTER TRACTS THAT CONNECT THE CEREBRAL CORTEX TO THE BRAINSTEM AND CORD |
| MENINGES ARE FOUND.. | AROUND THE BRAIN AND CORD (SO THEY ARE ONLY IN THE CNS!) |
| LOCATION OF PIA MATER | INNERMOST MENINGE DIRECTLY AGAINST THE BRAIN & CORD |
| LOCATION OF ARACHNOID | MIDDLE MENINGE |
| LOCATION OF SUBARACHNOID SPACE | BWETWEEN PIA AND ARACHNOID |
| CSF IS FOUND IN... | SUBARACHNOID SPACE |
| CSF IS PRODUCED IN... | CHOROID PLEXUSES |
| CSF IS RESORBED INTO THE BLOOD THROUGH... | ARACHNOID VILLI |
| MOST STROKE OCCUR... | MIDDLE CEREBRAL ARTERY |
| VENOUS DRAINAGE OF THE FACE THAT CAN TRAVEL TO THE MENINGES AND CAUSE MENINGITIS | CAVERNOUS SINUS |
| 2 SUPPORTIVE CELLS OF PNS | SATELLITE CELL, schwann cell |
| THE ONLY SYNAPTIC FIBER THAT SECRETES NOREPI NEUROTRANSMITTER | 'POST'SYNAPTIC SYMPHATHETIC FIBERS |
| THIS AREA IS THE TRUE EPIDURAL SPACE IN THE CORD | DURAL SAC |
| SEGMENT OF SKIN INNERVATED BY A SINGLE SPINAL NERVE | DERMATOME |
| WHAT DO DENDRITIES NEVER HAVE | MYELIN |
| ASTROCYTES ARE FORM (2) | 1)BLOOD-BRAIN BARRIER 2)FORM SCAR TISSUE |
| PART OF THE BRAIN KNOW AS THE "SENSORY RELAY CENTER" | THALAMUS |
| VENTRAL =____ AND IS SENSORY/MOTOR | ANTERIOR, MOTOR |
| DORSAL =____ AND IS SENSORY/MOTOR | POSTERIOR, SENSORY |
| produce multiple myelin segments in the CNS | oligodendroglia |
| how does CSF travel? | in order 1)lateral ventricles 2)interventricular foramen 3)3rd ventricles 4)Cerebral Aqueduct 4)4th ventricle |
| A special function of *NEUROLEMMA =BASEMENT MEMBRANE =ENDONEURIUM | can regenerate injured/cute fibers. |
