1. Chapter 11- Nervous System II PowerPoint Presentation to accompany Hole’s Human Anatomy and Physiology, 10 th edition , edited by S.C. Wache for Biol2064.01

2. You are responsible for the following figures and tables : Review Fig. 10.7. Differentiate CNS and PNS general tasks. Compare Fig. 11.5 - Structure of the CNS - the brain and spinal cord. Compare Tab. 11.9 and Fig. 11.29 - Components of the PNS Fig. 11.1 , 11.2 - meninges. Fig. 11.3, 11.4 - CSF. TB, blue box, p. 368 Clinical Applications 11.1 - Spinal tap. Fig. 11.6 - Structure of the spinal cord. Fig. 11.7 - Define 'reflex arc‘. Fig. 11.8, 11.9 - Examples: Knee-jerk reflex, withdrawal reflex. Tab. 11.2 - Study the parts of a reflex arc. Fig. 11.15, Tab. 11.7 - CNS/ Brain structure - Read p.388-391, endocrine functions. Fig. 11.16 - Note fissures, sulci, gyri. Fig. 11.17, 11.18 - Areas of the cerebrum. Tab. 11.5 - Functions of the cerebral lobes. Fig. 11.25. PNS / Cranial nerves . Fig. 11.26. The vagus nerve # X, is important. Fig. 11.6.- CNS/ Spinal cord structure. Fig. 11.29 - PNS/ Spinal nerves - (see table in the attached lecture handout). Fig. 11.35 - ANS innervates smooth muscle and glands. Fig. 11.40 - sympathetic / parasympathetic nerves (see diagram in the attached lecture).

11. Note dorsal and ventral roots.

14. Note the pathway that the impulse travels. neuron neuron neuron neuron

16. (Fig. 11.8) Note the pathway that the impulse travels. neuron neuron

18. Note the pathway that the impulse travels. neuron neuron neuron neuron

23. Note decussation area.

26. Note the lobes, fissures and sulci.

29. Brain Areas and Their Functions (Tab. 11.5) visual association area / perceptions occipital lobes Wernicke’s speech comprehension area; primary auditory / hearing association area temporal lobe gustatory area parietal lobe / along lateral sulcus primary olfactory area, Broca’s speech motor area frontal lobe concerned autonomic functions , limbic system hypothalamus integrates neurons for short-term memory thalamus is part of the diencephalon short-term memory processing, limbic system (emotions and motivation) lateral ventricle hippocampus / internal frontal lobe areas Function Region of Brain

30. Cerebral Functions (Fig. 11.16)

33. Cerebral Lobes (Figure 11.18)

50. Fig. 11.24 Epineurium : outer layer of connective tissue Perineurium : sleeve of looser connective tissue surrounding a fascicle Endoneurium : loose connective tissue surrounding each nerve fibers

56. Note : nerve cells are neurons. Note the spelling !!! Also note the pathway that the impulse travels !

57. Sympathetic Division of Motor Nerves Fig. 11.37 – note the dorsal and ventral roots.

58. Fig. 11.36 – note the meninges, dorsal and ventral roots. Note that the spinal nerves are mixed function nerves [AM-PS].

61. Fig. 11.38 – ANS preganglionic sympathetic fibers arise from the thoracic and lumbar regions of the spinal cord.

62. Fig. 11.40 – ANS preganglionic parasympathetic fibers arise from the brain and sacral region of the spinal cord.

64. Fig. 11.40 – note that most sympathetic fibers in the thoracic and lumbar regions are adrenergic and secrete norepinephrine / epinephrine
