  10. Joint surface where one bone meets another covered with a layer of Hyaline cartilage is called:
    Articular cartilage
  11. Bone is covered with a sheath called:
  12. Growth plate is called
    Epiphyseal plate
  13. Two layers of compact bone with spongy middle layer is called
  14. Bone forming cells
  15. Former osteoblasts
  16. Stimulates insulin secretion by pancreas, increases sensitivity in adipocytes, and limits growth of adipose tissue
  17. Bone dissolving cells that develop from blood cells
  18. Osteoblasts secrete
  19. Inorganic calcium phosphate salt synthesized by osteoblasts

  21. Brittle bone disease "without collagen"
    Osteogenesis imperfecta
  22. Calcified hard bone, sponge-like appearance
    Spongy Bone
  23. Thin plates of spongy bone
  24. Soft tissue of marrow cavity
    Bone marrow
  25. Two types of bone marrow
    Yellow and Red
  26. Marrow found in axial skeleton
    Red Bone Marrow (myeloid tissue)
  27. Hemopoietic tissue (produces red blood cells)
    Red bone marrow
  28. Fatty Marrow
    Yellow Marrow
  29. Where is most red marrow found?
    In children
  30. Where is most yellow marrow found?
    In adults
  31. Formation of bone
    Osteogenesis (ossification)
  32. Bone develops by two methods:
    Intramembranous and endochondral ossification
  33. Produces flat bones of skull and most of clavicle
  34. Process in which bone is preceded by hyaline cartilage "model" that becomes replaced by osseous tissue; begins in fetal development and continues into 20's (most bones of body)
    Endochondral ossification
  35. Two directions bones grow:
    Length and width
  36. Growth in length:
  37. Cartilage growth from within
    interstitial growth
  38. Bone growth in width
    Appositional growth
  39. Condition where long bones of limbs stop growing in childhood:
    Acondroplastic dwarfism
  40. Condition where a deficiency of growth hormone stunts growth in all of bone
    Pituitary dwarfism
  41. States that the architecture of a bone is determined by the mechanical stresses placed upon it, and the bone thereby adapts to withstand these stresses:
    Wolfe's Law of Bone
  42. Bones are continually:
  43. Crystallization process in which calcium, phosphate, and other ions are taken from blood plasma and deposited in bone tissue
    Mineral deposition
  44. Abnormal calcification
    Ectopic ossification

    1,100; 99
  46. Calcium deficiency
  47. Blood calcium in excess
  48. Depends on a balance between dietary intake, urinary and fecal losses, and exchanges with the osseous tissue
