The document discusses different tissues in the body including bones, muscles, and nerves. It provides descriptions of key terms like diaphysis, periostium, spongy bone, intramembranous bones, lacuna, ATP, rigor mortis, all-or-none response, myofibril, latent period, dendrites, myelin, resting membrane potential, reflex arc, threshold, and sarcomere. It also includes questions about tissues, bones, muscles, nerves, and hormones.

9. The long, shaft-like middle portion of a bone such as the femur

10. Diaphysis

11. Bones are surrounded by a very thin, very tough outer covering called this

12. Periostium

13. Long bones have an epiphysis made of this type of bone; it is very porous and lightweight

14. Spongy Bone

15. Bones that develop between two sheet-like layers of connective tissue are called this

16. Intramembranous Bones

17. These microscopic chambers found in bone tissue are responsible for housing osteocytes and are often found in concentric circles surrounding a central canal containing blood vessels for nourishment

18. Lacuna

19. A muscle cramp can be caused by a lack of this all-important energy storing cellular molecule

20. Adenosine Triphosphate (ATP)

21. A condition that sets in shortly following death. It is caused by constant contact between myosin and actin due to lack of ATP

22. Rigor Mortis

23. The idea that when a muscle fiber contracts it will do so with all of its strength

24. All-or-none Response

25. A unit that extends the length of a muscle fiber and is composed primarily of actin and myosin is called this

26. Myofibril

27. The potion of this myogram labeled A is called A

28. Latent Period

29. The part of a typical neuron that receives incoming signals from other neurons or from sensory organs

30. Dendrites

31. Myelinated nervous tissue looks like this

32. White

33. The charge difference found across a neurons while at resting membrane potential

34. Positive outside, Negative inside

35. The cause for repolarization of a neuron following an action potential

36. Na ions diffusing into cell, K ions diffusion out of cell

37. The four types of neruoglial cells and their primarly function

38. Astrocytes - Blood brain barrier Oligodendrocytes - Myelination of CNS neurons Ependymal cells - Produce and circulate CSF Microglial cells - Phagocitize bacterial cells in CNS

39. Responsible for storing fat in your bone tissue

40. Yellow Bone Marrow

41. The primary function of red bone marrow is to form these

42. Red blood cells, White blood cells, Platelets

43. Within the nervous tissue known as the meninges, cerebrospinal fluid can be found in this space

44. Subarachnoid Space

45. In muscles, the layer of connective tissue that separates the muscle into fascicles

46. Perimysium

47. In the spinal cord, the anterior horns contain these kinds of axons

48. Motor

49. This neurotrasmitter is responsible for stimulating muscle fibers to contract

50. Acetylcholine

51. Following a fracture, these cells will help build new bone tissue

52. Osteoblasts

53. Movement of this ion across the neuron cell membrane results in depolarization during a action potential

54. Sodium

55. Muscle fibers that are likely to respond to intense, heavy loads

56. Fast-twitch

57. Daily Double!!

58. The correct order of its events are: Receptor Sensory neuron Interneuron Motor neuron Effector

59. Reflex Arc

60. The name of the part of an action potential at which the neuron’s potential in greatly reduced below that of resting membrane potential is called this

61. Hyperpolarization

62. Slow twitch fibers respond to this type of exercise

63. Light, prolonged exercise

64. Which channels are open at the point labeled A on this graph of An action potential? A

65. Sodium channels only

66. The part of an action potential that acts as the tipping point that sends the neuron through the sequence of depolarization and repolarization

67. Threshold

68. The repeating units of a myofibril

69. Sarcomere

70. Final Jeopardy What hormone does the liver make in response to low blood-oxygen levels?

71. Erythropoietin
