  1. 1What is not true regarding osteoclasts?
    1. Aprevent overgrowth/too much bone matrix depostion
    2. Bwork via HCL acid, proteolytic enzymes, and phagocytosis
    3. Crelease calcium into the blood
    4. Dhas RANK-L on it's surface and binds to RANK on osteoblasts
  2. 2Binding of RANK-L and RANK reduces osteoblast activity.
    1. ATrue
    2. BFalse
  3. 3[blank_start]OPG[blank_end], whose production is stimulated by estrogen, plays a big role in bone homeostasis. It inhibits RANK-L from binding to RANK by acting as a competitive inhibitor. Doing this disengages [blank_start]osteoclast[blank_end] activity, thus promoting [blank_start]osteoblast[blank_end] activity.
    1. AOPG
    2. Bosteoclast
    3. Costeoblast
  4. 4The parathyroid releases [blank_start]calcitonin[blank_end] (which is actually made in the thyroid) which [blank_start]decreases[blank_end] calcium concentration in the blood. This means there is increased [blank_start]osteoblast[blank_end] activity.

    The parathyroid releases [blank_start]parathyroid[blank_end] [blank_start]hormone[blank_end] ([blank_start]PTH[blank_end]) which [blank_start]increases[blank_end] calcium concentration in the blood. This eans there is increased [blank_start]osteoclast[blank_end] activity.
    1. Acalcitonin
    2. Bdecreases
    3. Costeoblast
    4. Dparathyroid
    5. Ehormone
    6. FPTH
    7. Gincreases
    8. Hosteoclast
  5. 5Bone Growth:

    3. [blank_start]Liver[blank_end]: [blank_start]Insulin-like[blank_end] [blank_start]Growth[blank_end] [blank_start]Factor[blank_end] [blank_start]1[blank_end]
    1. AGrowth
    2. BHormone
    3. CReleasing
    4. DHormone
    5. EGrowth
    6. FHormone
    7. GLiver
    8. HInsulin-like
    9. IGrowth
    10. JFactor
    11. K1
  6. 6Bone Growth pt. 2:

    Liver makes IGF-1 and will also produce more [blank_start]GH[blank_end]
    b/c
    IGF-1 has [blank_start]positive[blank_end] feedback loop on GH
    but
    IGF-1 has a [blank_start]negative[blank_end] feedback loop for GHRH, which maintains balance b/c it can shut down GH
    1. AGH
    2. Bpositive
    3. Cnegative
  7. 7Vitamin D helps with [blank_start]calcium[blank_end] [blank_start]absorption[blank_end]. That is, if you have low vitamin D, you might have a harder time depositing calcium into your bones, therefore having [blank_start]weaker[blank_end] bones. Vitamin D comes primarily from the sun but can also be obtained from the diet (eggs, dairy, [blank_start]seafood[blank_end].) Vitamin D specifically is metabolized in 3 different places: first, the [blank_start]skin[blank_end] where it is initially absorbed, then the [blank_start]liver[blank_end] where it's converted into a useable form, and finally the [blank_start]kidneys[blank_end] where it's activated for usage.
    1. Acalcium
    2. Babsorption
    3. Cweaker
    4. Dseafood
    5. Eskin
    6. Fliver
    7. Gkidneys
  8. 8Hormones in exercise:

    When you first begin exercise, most of your energy is from burning carbohydrates and lipids. This is because [blank_start]catecholamines[blank_end] (from the adrenal medulla and NOT steroids,) [blank_start]growth[blank_end] hormone (anterior pituitary gland), and [blank_start]cortisol[blank_end] (from zona fasiculata of adrenal cortex) promote breaking down of [blank_start]glycerol[blank_end] and fatty acids.

    (BTW:
    The pancreas stores [blank_start]insulin[blank_end]. [blank_start]Insulin[blank_end] decreases blood glucose levels by promoting cellular uptake of glucose from the blood.
    The liver stores [blank_start]glycogen[blank_end]. [blank_start]Glycogen[blank_end] increases blood glucose levels by having more glucose released into the blood.)

    During exercise, there is an [blank_start]increased[blank_end] muscle sensitivity to insulin due to the [blank_start]GLUT-4[blank_end] receptors which leads to [blank_start]increased[blank_end] glucose uptake by muscle cells.
    1. Acatecholamines
    2. Bgrowth
    3. Ccortisol
    4. Dglycerol
    5. Einsulin
    6. Fglycogen
    7. GInsulin
    8. HGlycogen
    9. Iincreased
    10. JGLUT-4
    11. Kincreased
