6As the blood clot disappears during healing by primary intention, what feature forms?
- ADermal scar
- BGranulatory bundle
- CFibrin mesh
7Healing by primary intention:
The wound edges are brought close together so that there is a narrow incision. The wounded area fills with a [blank_start]blood clot[blank_end] which has a [blank_start]fibrin[blank_end] mesh that acts as a framework for cell growth. The surface of the wound dehydrates which forms a [blank_start]scab[blank_end]. There is [blank_start]acute[blank_end] inflammation around the edges of the wound. The epidermis thickens and grows along the cut edge of the dermis to meet in the midline. [blank_start]Granulation[blank_end] tissue grows into the blood clot that filled the wound space and this produces a [blank_start]dermal[blank_end] scar.- Ablood clot
- Bfibrin
- Cscab
- Dacute
- EGranulation

8The inflammatory reaction is less intense in healing by primary intention.
- AVerdadeiro
- BFalso
9Wound contraction is higher in wounds healing by secondary intention.
- AVerdadeiro
- BFalso
10Wound contraction is due to cells specifically known as...

11If a wound is infected, surgeons will...
- ATry to close the wound so it heals by primary intention

13Healed wounds don't get any stronger after approximately...
- A3 months
- B1 week

16Vitamin C deficiency interferes with
- ACollagen synthesis

- AVerdadeiro
- BFalso
25A bone fracture disrupts blood vessels. This results in...
- AHaematoma
- BDermal scar
- CAngiogenesis
26Osteoblasts which help to deposit bone and repair fractures are sourced from where?
- ABone ends
- BPeriosteum
- CSpleen
- DThymus
27Deposition of the uncalcified matrix during bone healing anchors the bone ends but [blank_start]does not[blank_end] give structural rigidity. This is known as the [blank_start]soft[blank_end] tissue callus. When [blank_start]woven[blank_end] bone is deposited this forms teh [blank_start]bony[blank_end] callus and structural rigidity increases with time to allow weight to be put on the bone. Eventually the [blank_start]bony[blank_end] callus is remodelled and woven bone is replaced by [blank_start]lamellar[blank_end] bone with the m[blank_start]edullary[blank_end] cavity being restored (bone marrow chamber).
- Adoes not
- Bsoft
- Cwoven
- Dbony
- Ebony
- Flamellar
- Gedullary
28The soft tissue callus is associated with
- AWoven bone
- BLamellar bone
- CUncalcified bone matrix
29Select the statement that is true
- AWoven bone has collagen fibres randomly oriented whereas lamellar bone has collagen fibres arranged along lines of stress
- BWoven bone has collagen fibres oriented parallel whereas lamellar bone has collagen fibres arranged randomly
- CThe soft tissue callus is associated with lamellar bone
- DUncalcified bone matrix is deposited by osteoclasts which originate from the periosteum around the bone
30Uncalcified bone matrix is also known as...
- AOsteoid
- BOsteoclast
- COsteocyte
- DOsteoblast
- EOsteoma
- FOsteomatous matrix
31Select the correct order from fracture to the healing of a bone fracture.
- AHaematoma -> Osteoid -> Woven bone -> Lamellar bone
- BWoven bone -> Lamellar bone -> Haematoma -> Osteoid
- COsteoid -> Woven bone -> Haematoma -> Lamellar bone
- DOsteoid -> Haematoma -> Woven Bone -> Lamellar bone
32Woven bone is a similar strength to lamellar bone.
- AVerdadeiro
- BFalso
33Bone healing is quicker in
- AChildren
- BAdults
34Problems with bone healing:
D[blank_start]eformity[blank_end] - due to malalignment when repositioning fracture
Soft tissue getting in between broken bone
Delayed union progressing to [blank_start]Non[blank_end]-union - fracture ends keep moving
Pseudo[blank_start]arthrosis[blank_end] - [blank_start]synovial[blank_end] cavity at the site of the fracture
Avascular [blank_start]necrosis[blank_end] - death of a section of bone due to is[blank_start]chaemia[blank_end]
Osteo[blank_start]myelitis[blank_end] - especially in open fractures- Aeformity
- BNon
- Carthrosis
- Dsynovial
- Enecrosis
- Fchaemia
