NERVOUS SYSTEM EXAM EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED)

,NERVOUS SYSTEM EXAM EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED) 1. Study of nervous system correct answer neurology 2. Functions of nervous system correct answer sensation (internal and external), integration (interpretation and response to sensation), motor control (responses via muscular, glandular control) 3. Systems in body that control/adjust activities of other systems correct answer nervous system (rapid, transient response) and endocrine system (slower and of longer duration) 4. Organization of nervous system correct answer 1. Sensations= incoming calls 2. Associations made in cns= dispatch hq 3. Motor control of muscles, glands, etc. 5. Cns correct answer -consists of brain and spinal cord -neurons -where sensory info is interpreted (thoughts and emotions produced) -initiates motor impulses 6. Pns correct answer nerves between cns and receptors/effectors that emerge from the brain and spinal cord -afferent (sensory) and efferent (motor) divisions 7. Efferent division of pns correct answer divided into somatic nervous system (skeletal muscle) and autonomic nervous system (smooth muscle, cardiac muscle, and glands) 8. Ans divisions correct answer parasympathetic and sympathetic 9. Nervous tissue cell types correct answer derived from embryonic ectoderm -neurons (nerve cells) -neuroglia/glial cells (support and protect) -neuroglia outnumber neurons 5 to 1 10. Astrocytes (neuroglia) correct answer star shaped -wrap around neurons -form blood brain barrier provide scaffolding 11. Oligodendrocytes correct answer provide myelin sheathing around the axons of neurons improve nerve impulse -nodes of ranvier -myelin make white vs. Gray matter 12. Microglia correct answer "little eaters" 13. Ependymal cells correct answer ciliated glial cells lining the ventricles of the brain -help to create and circulate csf 14. Schwann cells correct answer neurolemmocytes -similar to oligodendrocytes -wrap themselves around axons -cell membrane= axolemma -superficial covering= neurolemma 15. Satellite cells correct answer similar to schwann cells, but enclose ganglia only 16. Neurons correct answer propagate and sustain action potential, or nerve impulse -many mitochondria; very active -cell body, axon, dendrite 17. Cell body of neuron correct answer nucleus -often in clusters 18. Dendrite of neuron correct answer protrudes from cell body and receives impulses 19. Axon (nerve fiber) of neuron correct answer myelinated -protrudes from cell body and has axon terminals with synaptic bulbs 20. Distal end of synaptic bulb correct answer telodendrites 21. Synapses correct answer specialized sites where neurons communicate with other cells 22. Anaxonic neuron classification correct answer without an axon -function: interneurons -found only in cns 23. Unipolar (pseudounipolar) neuron classification correct answer 1 fiber which lies alongside the cell body -sensory in function 24. Bipolar neuron classification correct answer 2 fibers
