Muscle fibres do not divide very often. So there are less chances of making mistakes in the chromosomes and formation of cancer cells. So you rarely get cancer of the muscles.

What is the description of a chromatin fiber?
A chromatin fiber is the point at which DNA in chromatin is higher then the nucleosome. Chromatin fibers occur when the linear array of the nucleosome fold into a tighter fiber.
Do hyperplasia of muscle cells occur in all muscle types?
Hyperplasia affects the all types of muscle cells.
What does uncontrolled cell division occur in?
cancer
Do wildfires occur in the UK?
Yes but very rarely. It is usually heathland or peat.
Why does ptosis occur?
Ptosis may occur because the levator muscle's attachment to the lid is weakening with age.
Does dairy cause joint pain?
No. Smoking causes lung cancer , Skin Disease, and teeth to rot, but there is no sign of it being able to cause joint pain.
Why metastasis does not occur in spleen and muscle?
Due to absense of lymph in spleen it is not affected by malignant cancer
The smallest functional unit of the muscle fiber?
The smallest functional unit of a muscle fiber is the sarcomere. Sarcomeres are composed of actin and myosin filaments arranged in a repeating pattern, allowing for muscle contraction and relaxation to occur. They are responsible for the striated appearance of skeletal muscle under a microscope.
Must skin cancer moderate dysplastic nevus be removed?
Dysplastic nevi are not actually considered cancer. Sometimes melanomas can occur within one, but rarely. The presence of dysplastic nevi are indicative of an increased risk for cancer in the future. The more in number you have, the more likely melanoma will occur, usually as a new "mole." Most doctors remove moderate to severe displastic nevi.
How do the nerve impulses get from the sarcolemma plasmalemma into the individual muscle fiber?
Nerve impulses travel down from the neuron and cause ACh to be released at the axon terminal. If enough Ach binds to the receptors on the plasmalemma the action potential is tranmitted through the whole muscle fiber because Na+ enters the cell and depolarize it. The action potential travels along the T-tubules. These transmit it to the Sarcoplasmatic Reticulum which releases Ca2+ into the muscle fiber (as do the T-tubules themselves). The Ca2+ frees the bindingsite for myosin on actin so that contraction can occur.
What can occur from secondhand smoke?
Lung cancer or just cancer.
Which parts of the body can you have cancer?
Cancer can occur anywhere in/on the body.
What time can you have cancer?
Cancer can occur at almost any age.
Do floods occur in Central America?
Very rarely
Does dietary fiber reduce the risk of cancer?
I know that I ate a very high fibre diet most of my life but was diagnosed with ovarian cancer, so I would say no to your question. Other factors could contribute to getting ovarian cancer, such as the other foods eaten and the environment. There are scientists who say that fibre can decrease the chance of cancer, so I guess that Fibre can help, but there is currently no definite answer. Hope this helps!
In what age do people have cancer?
Cancer can occur in the human body at any age.
How does metastasis occur?
Metastasis can occur during any type of cancer. It can happen early on or not at all. It is the spread of cancer through different organs.
