what is Metaplasia?
Give this one a try later!
a reversible change in which one adult cell type is replaced by another
adult cell type)
Caused by what? Usually occurs as a response to chronic irritation and
inflammation
Example: if you smoke, the cells lining your respiratory tract may change
from their normal type into a different type that's more resistant to the
, harmful effects of smoke. While this change may help protect the tissue in
the short term, it can also increase the risk of other health problems in the
long run.
What is phenotype?
Give this one a try later!
(the cake) the physical and behavioral characteristics that result from the
combination of genes, can be influenced by both genes and environment.
the role of transcription
Give this one a try later!
the process tat copies the message in a gene and turns it into messenger
RNA (mRNA)
-mRNA molecules provide the instructions for making a protein molecule.
What are the causes of cell injury?
Give this one a try later!
physical--> fell down and broke a bone
chemical--> medications/drugs, environmental things like Lead
biologic--> viruses, bacteria
deficiencies--> iron (not getting enough red blood cells, not enough O2 or
protein that can recover tissues easily)
, free radicals --> things w/ unpaired electron that are floating around in
your body & if they come to interact things in your cells like lipids,
carbohydrates, they can damage the cell membrane & the cell DNA itself.
Neoplastic classification

uncontrolled proliferation (cancer)

caused by abnormalities in genes (down syndrome)
what does morbidity mean?
