  1. ObamaCare • 7 pm Wednesday, McMillan Theater • Dr. Moss will explain “Obamacare” Why should you know about Obamacare? Interviewers may ask you about Obamacare and your opinions of it!

  2. 1QQ#10 for 10:30 Choose two of the following false or misleading statements and make the appropriate corrections. Be sure to write the number of the questions you choose. • In a person with acromegaly, high levels of GH, IGF-1, and GHRH would indicate primary hyposecretion. • Endemic goiter is an example of secondary hyposecretion. • During times of stress, elevated levels of cortisol enhance inflammatory and immune responses. • Prolonged treatment with glucocorticoids can lead to atrophy of the adrenal medulla. • Pithing the brain of a frog eliminates the wiping reflex.

  3. 1QQ#10 for 11:30 Choose two of the following false or misleading statements and make the appropriate corrections. Be sure to write the number of the questions you choose. • In a person with acromegaly, high levels of GH, IGF-1, and GHRH would indicate primary hyposecretion. • Endemic goiter is an example of secondary hyposecretion. • During times of stress, elevated levels of cortisol enhance inflammatory and immune responses. • Prolonged treatment with glucocorticoids can lead to atrophy of the adrenal medulla. • Pithing the brain of a frog eliminates the wiping reflex.

  4. S 6 Why are NSAIDs preferable to Glucocorticoids for treating inflammation andarthritis? Consider the HPA axis and the effects of long-term dosing with glucocorticoids on ACTH secretion and the Adrenal Cortex.

  5. S 6 Neurons? Endocrine cells? Neuroendocrine cells? Neurons and endocrine cells are very involved in homeostasis. To Chapter 6!

  6. Neurulation

  7. Dorsal root ganglion sensory (afferent) neuron cell body Somatic motoneuron cell body Autonomic motoneuron cell body (preganglionic) Autonomic motoneuron cell body (ganglionic) Interneuron cell body (all within CNS) Role of Growth Cones

  8. S 10 Communication in The Vertebrate NS Reflexes require some part of the CNS (i.e. frog lab) Blood pressure Blood gases and pH Muscle stretchPain Skin temperature Hair movement Light, Taste, Odor Touch, Pain, Temperature, Etc. Peripheral nerves are “mixed” (have afferent & efferent axons) Signaling over short and long distances Dimensions of neurons

  9. Descending neurons (corticospinal interneurons) from brain to spinal cord Sensory (afferent) neurons from hoof to brain S 11 If Nodes of Ranvier are 1 mm apart: How many Schwann cells to myelinate the 2 meters of a sensory axon from hoof to dorsal root ganglion near spinal cord? How many oligodendries to myelinate the 2 meters of the sensory axon ascending in spinal cord to brain?

  10. S 12 Fig. 06.03 Orthograde =anterograde retrograde

  11. S 13 Axonal Transport • Orthograde = Anterograde = from soma to terminals • slow……1-2 mm/day • fast …..200-400 mm/day (kinesin) • Retrograde = from terminals to soma • fast….200-400 mm/day (dynein) • What gets transported and why? • Axonal transport is too slow for rapid signaling, so…
