water black fat white
t2
water white fat black
PET uses
synctiography
synctiography
radioactive chemical
5 principles of density in X-ray
air adipose soft tissue bone metal
the higher the atomic number the
more attenuation/scatter (less of the beam passes through)
what does tropomysoin wrap around
actin
actin or myosin found in the middle part of sarcomere
myosin
middle line in sarcomere called
M line (think middle line)
tight junctions
create a water tight seal (found near the top) makes layer of cells impermeable barrier
adherens junction
role in adhesion
desmosome
adhesion of cells laterally
hemidesmosomes
adhesion of cells to ECM (basal)
can skeletal muscle regenerate
no , but hyperplasia of satelite cells follows muscle growth
can cardiac muscle cells regenrate
no
can smooth muscle cells rehenerarte
yes
layers of the GI
mucosa submucosa muscularis externa serosa
mucosa
epithelium lamina propria muscularis mucosa
submucosa and serosa
connective tissue with blood supply and glands etc
eosinophil
neutrophil
basophil- think bluberry
- full of heparin and histamine granules
monocyte–> macrophage
B/T cell cant distinguish
granulocytes
part of myeloid lineage
neutrophil
eosinophil
basophil
what stimulates erythropoiesis
erythropoetin
- produced by kidneys produced in response to hypoxia
reticulocytes have lots of
RNA but not nucleus
RBC production
proerythroblast
early erythroblast
intermediate erythroblast
late erythroblast
nuclear excision
reticulocyte
RBC
blood cells made by the bone get released via the
vena commitans (sinnosoidal)
during haemostasis (response for the prevention and stopping of bleeding/haemorrhage)
1) vasoconstriction
2) fibrin plug formation
3) blood clot
pathways for blood clottign
intrinsic -endothelial acitvation
extrinsic- trauma
common pathway (factor X)
production of fibrin
Prothrombin ——> (X) thrombin
fibrinogen (thrombin) —> fibrin
fibrin produces a fibrin mesh via cross linking
daily energy expenditure
basal metabolic rate + eating induce thermogenesis + physical activity level

inequity
unfair, avoidable differences arising from poor governance, corruption or cultural exlcusion
inequality
uneven distribution of healrh as a result of geents or other unavoidable factors
