1Granulation tissue appearance includes [blank_start]capillary sprouts[blank_end] from venular endothelium
--> perpendicular to the wound surface, leaky ([blank_start]oedema[blank_end], [blank_start]exudate[blank_end] (protein rich).
--> [blank_start]Fibroblasts[blank_end] growing in from sides and base of wound: makes collagen type 3 then 1, change phenotye to [blank_start]myofibroblast[blank_end] ( wound [blank_start]contraction[blank_end] ), hyaluronic acid and sulfated proteoglycans made.- Acapillary sprouts
- Boedema
- Cexudate
- DFibroblasts
- Emyofibroblast
- Fcontraction
2Bone fracture is a bone lesion which leads to bone discontinuity
- AVerdadeiro
- BFalso
3Bone repair depends on;
Type of [blank_start]break[blank_end] - Result of strength & direction of applied force --> [blank_start]axial[blank_end] force (compressional fracture), Torsion force ([blank_start]spiral[blank_end] fracture), Combined [blank_start]torsion[blank_end] and compressional force leads to an [blank_start]angel[blank_end] and displaced fracture
Adjacent tissue damage effects [blank_start]rate[blank_end] of repair. (e.g muscles)- Abreak
- Baxial
- Cspiral
- Dtorsion
- Eangled
- Frate
- Ggrowth
- Hdeterioration
4which one of these are bone repair host factors?
- AAge, nutrition & overall health
- BSite of injury
- Cimmobilisation of fracture
- Ddegree of damage
5healing of bone is triphasic
- AVerdadeiro
- BFalso
6Healing of bone phases
1: [blank_start]Inflammatory phase[blank_end]
2: Reparative
3: [blank_start]Remodelling[blank_end]- AInflammatory phase
- BRemodelling
7What would most likely to occur after 2 days of bone injury?
- ABlood clot formation
- BIngrowth of capillary sprouts & fibroblasts from wound edge
- CFibrocartilage formation
- Dtrabeculae of cancellous bone unite
8Callus formation into chondrocytes is in remodelling phase of bone repair.
- AVerdadeiro
- BFalso
9Bone Callus is a collar of [blank_start]osteogenic[blank_end] cells around a bone fracture. Has the same function as granulation tissue.
- Aosteogenic
10In the reparative phase (II) of bone repair, Trabeculae of [blank_start]cancellous[blank_end] bone slowly unite. There's [blank_start]capillary[blank_end] ingrowth from edge of marrow cavity. [blank_start]Osteoblasts[blank_end] differentiate, cancellous bone laid down. [blank_start]Fibrocartilage[blank_end] formed in less vascular areas. After long periods of time, [blank_start]osteoclasts[blank_end] start to remodel. Marrow slowly replaced.
- Acancellous
- Bdense
- Ccapillary
- Dveins
- EOsteoblasts
- Fchondroblasts
- GFibrocartilage
- HHyaline cartilage
- Iosteoclasts
11In [blank_start]Remodelling[blank_end] phase (III) of bone repair, it may take years. Bone contours are re-organised and excess [blank_start]callus[blank_end] removed.
- Acallus
- Bscar tissue
- CRemodelling
- DInflammatory
- EReparative
12What happens after weeks of bone repair?
- AChondrocytes multiply
- BAll cancellous bone converted of to lamellar bone
- CChondrocytes mineralises & dies after callus is vascularised
- DIt is the remodelling phase, callus is removed
13Surgical incisions in bone --> healing with minimal [blank_start]callus[blank_end] formation and minimal disruption to the bone's ordered structure
- Acallus
14Neuronal cells are mitotic and can be replaced
- AVerdadeiro
- BFalso
15What is Gliolisis?
- AProliferation of neuroglia repairing damage
- BGlial cells dying off
- CNeurons proliferating
- DDendrites proliferating
16In PNS (Peripheral nervous system), nerve axons can be [blank_start]replaced[blank_end]. If Basement membrane of [blank_start]Schwann[blank_end] is disrupted, resorbed axons may miss each other resulting in a traumatic [blank_start]neuroma[blank_end]. If they are [blank_start]intact[blank_end], axonal growth has path to follow.
- Areplaced
- BSchwann
- Cmyelin sheath
- Dneuroma
- Eneuroblastoma
- Fcarcinoma
- Gintact
- Hremoved
17When basement membrane is intact; (PNS)
- AGrowth of axonal sprouts from surviving stumps begin at 4mm/day
- BThere is no axonal sprout growth.
- CMyelin sheath breaks down around axonal tip
18Tissue healing in liver - acute injury heals by complete regeneration, whilst chronic is usually leading to collapse of reticulin framework, along with surrounding by fibrosis also known as CIRRHOSIS.
- AVerdadeiro
- BFalso
19Which one of these are correct in regards to tissue healing in kidneys?
- ATubular epithelium can regenerate after damage
- BGlomeruli can regenerate - No scar tissue
- CGlomeruli cannot regenerate - Scar tissue formed
20Metaplasia is a form of healing in epithelial surfaces
- AVerdadeiro
- BFalso
21An example of metaplasia includes replacement of ciliated columnar epithelium to squamous type that is resistant to trauma in chronic smoking damaged individuals.
- AVerdadeiro
- BFalso
22Cardiac muscle cells are permanent and does not regenerate. Repairs by fibrosis
- AVerdadeiro
- BFalso
23Skeletal muscle has no ability of healing/regeneration at all.
- AVerdadeiro
- BFalso
24Smooth muscle has limited regeneration - can regenerate if loss is minimal
- AVerdadeiro
- BFalso
25Respiratory epithelium [blank_start]can[blank_end] regenerate. However, basement membrane must be intact and CT framework minimally disrupted. If basement membrane disrupted, [blank_start]fibrosis[blank_end] occurs.
- Acan
- Bcannot
- Cfibrosis
- Dinflammation
26Which one(s) of these answers are true of cartilage healing?
- AWill replace itself by superficial ulceration if damage is small
- BCannot replace itself
- CExtensive damage may have resultant haematoma following fibrosis
- DUndergoes aplastic changes
27Regeneration is good in tendon healing
- AVerdadeiro
- BFalso
