Explanation:
Regeneration in planarians depends on the presence of stem cells called neoblasts. These cells are distributed throughout the body and, when part of the worm has been amputated, they are activated to reform the tissues that have been removed.
If there was a dramatic increase in skeletal muscle cell damage and apoptosis, I would not expect a change in blood myoglobin and CK levels, because these markers are linked to cardiac muscle damage.
<h3>What does high CK-MB mean?</h3>
Elevated CKMB can be a sign of cardiac (heart muscle) damage or chronic kidney failure. At the onset of acute symptoms, after cardiac peaks, CKMB values are elevated after 3-6 peaks after 12-24 hours between 12-24 hours, values at 24-48-48.
With this information, we can conclude that if there was a dramatic increase in skeletal muscle cell damage and apoptosis, we would not expect a change in blood myoglobin and CK levels, because these markers are linked to cardiac muscle damage.
