MMED1007 EXAM QUESTIONS WITH
CORRECT ANSWERS
Acuity - CORRECT ANSWER✔✔-the ability to discriminate two objects that are close together
(25 micrometers)
Tissue processing - CORRECT ANSWER✔✔-- Fix
- Wash out fixative
- Dehydrate
- Wax
- Cut (microtome)
- Mount
- Rehydrate
- Stain
- Dehydrate
Eosin - CORRECT ANSWER✔✔-Acidic dye, stains pink, binds to basic groups like proteins,
cytoplasmic filaments and extracellular fibres
Haematoxylin - CORRECT ANSWER✔✔-basic dye, stains blue, binds to acid groups, like DNA and
RNA
PAS stain - CORRECT ANSWER✔✔-stains carbohydrates (basement membranes)
Pericytes - CORRECT ANSWER✔✔-help stabilize capillary walls and control permeability
,Myofibroblasts - CORRECT ANSWER✔✔-fibroblasts containing contractile fibers that are the
mechanism of wound contraction
myoepithelial cells - CORRECT ANSWER✔✔-Squeeze apocrine gland secretions onto skin surface
In response to hormonal or nervous signal
striated muscle - CORRECT ANSWER✔✔-A muscle that appears banded; also called skeletal
muscle, under voluntary control
Layers of Striated muscle - CORRECT ANSWER✔✔-- myofibril
- Muscle fibre
- Endomysium
- Fascicle
- Perimysium
- muscle
- Epimysium
striations of skeletal muscle - CORRECT ANSWER✔✔-Actin (thin)
Myosin (thick)
Made of repeating series of DARK ("A" bands) + LIGHT ("I" bands).
smooth muscle - CORRECT ANSWER✔✔-simple cigar shaped cells that are arranged in bundles
smooth muscle is found around most organs
innervated by motor neurones of autonomic motor system
,cardiac muscle - CORRECT ANSWER✔✔-Involuntary muscle tissue found only in the heart.
Has striations and intercalated discs
connective tissue - CORRECT ANSWER✔✔-It is an extracellular matrix of fibres running through
a gel substance called ground substance
Fibroblasts - CORRECT ANSWER✔✔-secrete extracellular fibres and ground substance
Myofibroblasts - CORRECT ANSWER✔✔-fibroblasts containing contractile fibers that are the
mechanism of wound contraction
Macrophages - CORRECT ANSWER✔✔-White blood cells that phagocytose damaged cells
stem cells - CORRECT ANSWER✔✔-unspecialized cells that retain the ability to become a wide
variety of specialized cells
Adipocytes - CORRECT ANSWER✔✔-fat cells
mast cells - CORRECT ANSWER✔✔-Cells that release chemicals (such as histamine) that
promote inflammation.
ground substance - CORRECT ANSWER✔✔-a gel like material, containing water and ions
- proteoglycans
- glyvosaminoglycans
- glycoproteins
they form a brush that hods on water to create the gel
supports cell migration and regulated metabolism, cell to cell signalling
, Collagen - CORRECT ANSWER✔✔-is the major form in most connective tissue, stains pink and is
laid down by fibroblasts
Reticulin - CORRECT ANSWER✔✔-Collagen type 3, does not Stain with H & E, found lots in
basement membranes
Elastin - CORRECT ANSWER✔✔-protein base similar to collagen that forms elastic tissue
central nervous system - CORRECT ANSWER✔✔-brain and spinal cord
periferal nervous system - CORRECT ANSWER✔✔-All other nerves in the body
Basic features of nerves - CORRECT ANSWER✔✔-- cell body
- Dendrites
- Axon
- Synapses
simple squamous epithelium - CORRECT ANSWER✔✔-single layer of flattened cells
simple cuboidal epithelium - CORRECT ANSWER✔✔-Made up of a single layer of cells that are
as tall as they are wide
simple columnar epithelium - CORRECT ANSWER✔✔-Made up of a single layer of tall cells that
fit closely together,
stratified squamous epithelium - CORRECT ANSWER✔✔-a thick layer of cells where the top
layer is squamous
