20. Answer:True

21. Conscious perception of somatic sensory impulses occurs here: _______.

22. Answer: Postcentral gyrus, also called primary sensory cortex

23. Visceral sensory pathways begin in receptors of the ________.

24. Answer: visceral organs / ventral cavity organs

25. The site of integration for visceral sensory pathways is the: __________.

26. Answer: Solitary nucleus

27. True or False: Visceral motor impulses are only conducted to organs in the ventral cavity.

28. True or False: Visceral motor impulses are only conducted to organs in the ventral cavity. Answer: false, they are also conducted to sweat glands, arrector pili, adipose tissue, and blood vessels.

30. Visceral motor neuron somas are located here: ____and here: _____. Answer: Lateral horn of spinal cord and some cranial nerve nuclei

31. True or False: Referred pain is perceived when a visceral sensory pathway stimulates a spinothalamic pathway.

32. Answer: True

33. Name the four autonomic effectors.

34. Answer: Smooth muscle, cardiac muscle, glands, adipose tissue

35. Intramural ganglia are located along some of the pathways of the _______ division of the ANS.

36. Answer: parasympathetic

37. Sympathetic impulses to the body wall and limbs synapse in _________ ganglia.

38. Answer: sympathetic chain

39. True or false: Autonomic ganglionic fibers always secrete acetylcholine.

40. Answer: false, other neurotransmitters include NE and NO

41. Nicotinic Ach receptors are found at excitatory synapses in autonomic ________.

42. Answer: ganglia

43. True or false: Dual innervation means an effector is innervated by both the somatic and autonomic nervous systems.

44. Answer: false, it means the effector is innervated by both ANS divisions. (SYM and PARA)

45. True or False: Sympathetic nerves innervate all sympathetic effectors.

46. Answer: False, they innervate thoracic cavity effectors; splanchnic nerves innervate abdominopelvic viscera, and spinal nerves innervate effectors in the body wall and limbs.

47. True or False: The suprarenal medullae are dually innervated and secrete NE and EPI in response to ANS activity.

48. Answer: False, they are only innervated by the sympathetic division.

50. Answer: low

51. True or false: Alpha (  ) and beta (  ) receptors exert their effects on effectors by increasing membrane permeability to sodium.

52. Answer: False, via cAMP or activating intracellular enzymes.
