What else can I help you with?
The repair of cardiac muscle and nervous tissue occurs only by?
fibrosis
Which muscle cells can not regenerate?
Cardiac muscle cells cannot regenerate, meaning that they have limited ability to repair and replace damaged muscle tissue. This is because most cardiac muscle cells are terminally differentiated and do not undergo cell division.
What are the two types of tissue repair?
The two types of tissue repair are regeneration, where damaged tissue is replaced with new functional tissue, and fibrosis, where damaged tissue is replaced with scar tissue made of collagen fibers. Regeneration is ideal as it restores normal tissue function, while fibrosis can lead to loss of function depending on the extent of scarring.
Why cardiac tissue cannot repair itself after damage?
Briefly describe why cardiac tissue cannot repair itself after damage? Cardiac muscle lacks stem cells and mature cardiac muscle fibers cannot go through mitosis. This is a network of specialized cardiac muscle fibers that provide a path for each cycle of cardiac excitation to progress through the heart.
How do you repair fibrosis?
Fibrosis is repair. When a tissue is damaged fibroblasts repair the damage and this process is called Fibrosis.
Which muscle cells have the greatest ability to regenerate smooth muscles skeletal or cardiac?
Smooth Muscle has the greatest ablility to regenerate.
Muscle tissue that is lost is replaced with what non contractile tissue?
skeletal muscle is made up of permanent cells - ie they never divide. this means if it is lost then it will heal by repair with organisation and progressive fibrosis = scar formation.
Which cellular organelles are absent in the cardiac muscle cell?
Cardiac muscle cells, or cardiomyocytes, lack certain organelles typically found in other cell types. Notably, they have fewer mitochondria compared to skeletal muscle cells, but they do contain many due to their high energy demands. However, they generally do not have a well-developed smooth endoplasmic reticulum or large amounts of glycogen granules, which are more prevalent in other types of muscle cells. Additionally, cardiac muscle cells lack satellite cells, which are involved in muscle repair and regeneration in skeletal muscle.
Is it true that if tissue damage is very severe tissue repair is more likely to occur by fibrosis or scarring?
fibrosis
What is a cardiac erosion?
Cardiac erosion refers to a rare mechanical complication of transcatheter aortic valve replacement (TAVR) where the valve can erode into the heart tissue. This can cause problems such as bleeding and damage to the heart muscle. Treatment may involve surgical repair or replacement of the eroded valve.
What neurons does the nervous system repair?
Yoga is the body abel to repair damage to the parts of the nervous system
What is a satellite cell?
A satellite cell is a type of stem cell found in skeletal muscle tissue. These cells play a key role in muscle repair and growth by proliferating and differentiating into new muscle fibers in response to injury or exercise.
