Necrosis
Apoptosis
injury
naturally
where does Apoptosis in Embryonic Development Happen?
feet and frog
human`s & head
human`s hand and feet
In a healthy adult human, billions of cells die in the bone marrow and intestine?
every day

Mutations in p53 gene are found in more than ............. of human cancers
50%
60%
70%
80%
In normal in p53 gene cell division when DNA ..............
damage
division
development
Multiply
-Mechanical damage
-Exposure to toxic chemicals
Necrosis
Apoptosis
In Apoptosis: programmed cell death, occur naturally to respond to
a- External signals
b- Internal signals
a and b
Occur without energy (passive)
Necrosis
Apoptosis
Occur naturally / not - Pathogenic
Apoptosis
Necrosis
in which type its happened as a result of injury and caused an inflammatory response.
Necrosis
Apoptosis
The cell swell and burst, spill and harm the nearby cells.
Apoptosis
Necrosis
Ordered. Needs a cascade of enzymes that promote cell death
Apoptosis
Necrosis
Apoptosis in Embryonic Development
This happens to human fetus hand and feet to form our
fingers and toes
fingers
toes
In other cases, cells die when the structure they form is
no longer needed
needed
If the damage is too extensive then p53 Activated and this leads to
apoptosis (programmed cell death)
necrosis (uncontrolled cell death)
