What else can I help you with?
Is the repair of cardiac muscle and nervous tissue done by fibrosis?
true
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.
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.
What two types of human tissue that do not undergo mitosis?
The two types of human tissue that do not undergo mitosis are nervous tissue and cardiac muscle tissue. Neurons, the primary cells in nervous tissue, typically do not divide after reaching maturity, which limits their ability to regenerate. Similarly, cardiac muscle cells, or cardiomyocytes, have a very limited capacity for division and repair, making heart tissue less regenerative after injury compared to other tissues.
Which muscle cells have the greatest ability to regenerate smooth muscles skeletal or cardiac?
Smooth Muscle has the greatest ablility to regenerate.
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.
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 muscle tissue is a multincleate?
Skeletal muscle tissue is multinucleate, meaning that each muscle fiber contains multiple nuclei. This characteristic allows for greater control and coordination of muscle contractions, as well as the ability to manage the demands of increased protein synthesis required for muscle function and repair. In contrast, cardiac and smooth muscle tissues are usually uninucleate.
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.
What is an annuloplasty?
An annuloplasty is the use of plastic to repair a cardiac valve.
What is the medical term meaning surgical repair of a muscle?
my/o = muscle -plasty = surgical repair Myoplasty is the surgical repair. Myorhaphy is the procedure to suture together a torn muscle after an injury.
