Presentation Transcript

  1. Chapter 9 Part II Review

  2. To remove the CSF during a lumbar puncture (spinal tap), fluid is removed from the : • Central canal • Sacral plexus • Gray commissure • Subarachnoid space

  3. A student’s ability to think is directly controlled by the… cerebrum cerebellum Medulla oblongata

  4. The portion of the nervous system that is most closely associated with the contraction of cardiac muscle is the • somatic nervous system • b) Hypothalamus • c) autonomic nervous system • d) cerebrum

  5. The part of the brain stem that includes the cardiac, vasomotor, and respiratory centers is the...

  6. The network of islands of gray matter within the brain that activates the cerebral cortex to a state of wake- fullness is the • corpora quadrigemina • b) reticular formation • c) limbic system • d) dentate nucleus

  7. In the case of a subdural hematoma resulting from a blow to the head, blood accumulates between the • dura mater and the skull • b) arachnoid mater and brain • c) dura mater and arachnoid mater • d) pia mater and brain

  8. Arachnoid mater Sub = below

  9. Which best illustrates the pathway of an impulse in a reflex arc? • receptor –motor neuron-associative neuron-sensory neuron- effector • b) effector-sensory neuron-associative neuron-motor neuron-receptor • c) receptor-sensory neuron-associative neuron- motor neuron-effector

  10. Reflex arc

  11. The dorsal root contains what type of neurons? • sensory/afferent neurons • Association/interneurons • Motor/efferent neurons

  12. This nerve arises form the cervical plexus and innervates the diaphragm: • Sciatic nerve • Brachial nerve • Phrenic nerve • Axillary nerve

  13. Dorsal Roots Ventral Roots Cross section of spinal cord

  14. The part of the brain that functions to coordinate voluntary muscle movements is the… cerebrum cerebellum Medulla oblongata

  15. The somatic nervous system contains nerves that run from the central nervous system to the • endocrine glands • b) smooth muscles of the gastrointestinal tract • c) muscles of the skeleton • d) heart Soma = body

  16. In the diagram below, which region of the human brain maintains balance and coordinates motor activities? cerebrum cerebellum Medulla oblongata

  17. The spinothalamic tract conducts impulses • that stimulate movement in skeletal muscles • b) up the spinal cord to the thalamus • c) from the thalamus to the cerebral cortex • d) down the spinal cord from the thalamus

  18. Which of the following is most closely associated with the diencephalon? • cerebral aqueduct • b) Thalamus • c) red nucleus • d) cerebral peduncles

  19. Which malfunction is described by the inflammation of the membranes surrounding the brain and spinal cord? • cerebral palsy • b) Polio • c) Meningitis • d) stroke -itis = inflammation

  20. The interconnected fluid-filled cavities within the brain are called • Ventricles • b) Atria • c) sinus

  21. Injury to which part of the brain would most likely result in loss of memory? cerebrum cerebellum Medulla oblongata

  22. Bonus points: Which lobe of the cerebrum stores memories?

  23. Which part of the human central nervous system is correctly paired with its function? a) spinal cord – coordinates learning activities b) medulla – maintains muscular coordination c) cerebrum – serves as the center for memory and reasoning d) cerebellum – serves as the center for reflex actions

  24. What would normally be found within the central canal of the spinal cord? • Blood • b. Myelin • c. cerebrospinal fluid • d. air

  25. What would normally be found immediately surrounding the central canal of the spinal cord? • white matter • b. gray matter • c. cerebrospinal fluid • d. the pia mater

  26. Cross-section of the spinal cord

  27. The innermost layer of the meninges is the… • Dura mater • Arachnoid mater • Pia mater

  28. The middle layer of the meninges is the… a. Dura mater b. Arachnoid mater c. Pia mater

  29. The outermost layer of the meninges is the… a. Dura mater b. Arachnoid mater c. Pia mater

  30. Cerebrospinal fluid is normally circulates in the: • Epidural space • Subdural space • Subarachnoid space

  31. A “mixed” spinal nerve: • Contains both nerves and tracts • Contains gray matter and white matter • Has both afferent and efferent neurons • Uses multiple types of neurotransmitters

  32. The cauda equina is formed by: • Myelin • Blood vessels extending down from the end spinal cord • Spinal nerves extending down from the end of the spinal cord

  33. This lobe is for: touch, understanding speech

  34. This lobe is for: sight and visual memory

  35. This lobe is for: planning, emotions, contains the frontal eye field and Broca’s area.
