1Trabecular vs cortical bone. Trabecular AKA [blank_start]__________[blank_end]; Cortical AKA [blank_start]__________[blank_end].
- ACancellous
- BCompact
2Bone matrix composition. Which of the following [mainly] gives bones its TENSILE strength:
- ACollagen
- BNon-collagenous proteins
- CBone mineral (Calcium & Phosphate as hydroxyapatite)
3Bone matrix composition. Which of the following [mainly] gives bones its COMPRESSIVE strength:
- ACollagen
- BNon-collagenous protein
- CBone mineral (Calcium & Phosphate as hydroxyapatite)
490% of bone cells are [blank_start]__________[blank_end] and are [blank_start]__________[blank_end].
- AOsteocytes
- BOsteoblasts
- CLining Cells
- DCollagen
- ELong-lived
- FShort-lived
- GOsteoclasts
5Which of the following are involved in FORMING bone:
- AOsteoblasts
- BOsteocytes
- CLining Cells
- DOsteoclasts
- ECollagen
6Which of the following are involved in RESORBING bone:
- AOsteoblasts
- BOsteoclasts
- COsteocytes
- DLining Cells
- ECollagen
7Which bone cells are the ones that are embedded in the bone matrix and involved in sensing mechanical forces (and/or apoptosing to trigger resorption)?
- AOsteocytes
- BOsteoclasts
- COsteoblasts
- DLining Cells
8OPG = ??
- AOsteoProteGerin
- BOsteoProGeterin
- COsteoProGerin
- DOsteoProteGeterin
9Classical Wnt pathway in bone. Wnt pathway allows [blank_start]__________[blank_end] to control bone mass – e.g. more mechanical force, more bending of bone, sensed by [above], less production of Sclerostin, more bone added.
- AOsteocytes
- BOsteoclasts
- COsteoblasts
- DLining Cells
10RANKL = ??
- AReceptor Activator of Nuclear factor Kappa-B Ligand
- BReceptor Activator of Necrotic factor Kappa-B Ligand
- CReceptor Activator of Nuclear factor Kappa-A Ligand
- DReceptor Activator of Necrotic factor Kappa-A Ligand
11Bone formation depends [most directly] on [blank_start]__________[blank_end] (numbers, activity, lifespan); Bone resorption depends [most directly] on [blank_start]__________[blank_end] (numbers, activity, lifespan).
- AOsteoblast
- BOsteoclast
- COsteocyte
- DLining Cell
12Match the following bone* cells to their function:
Amelobasts = [blank_start]__________[blank_end];
Cementoblasts = [blank_start]__________[blank_end];
Odontoblasts = [blank_start]__________[blank_end];
Osteoblasts = [blank_start]__________[blank_end];- AEnamel
- BCementum
- CDentine
- DAlveolar bone
13Cells of teeth: Ameloblasts lay down [blank_start]__________[blank_end], are [blank_start]__________[blank_end]; and [blank_start]__________[blank_end] have (do?) regeneration.

- CBiopsy
- DHitting with a sledgehammer and seeing whether it breaks (hint: technically true)
16What are caries?
- ACavities, possibly arising from bacteria and/or food
- BNot “cavities”, but possibly arising from bacteria and/or food
