What is the function of muscles?

The muscle performs many important functions for the body. It produces movement, maintains posture and gives shape to your body, stabilizes joints, and generates heat. Muscles protect your internal organs as well. The visceral or smooth muscles assist in the circulation of blood. The skeletal muscles are responsible for uncontrolled motions, and your cardiac muscles make your heart beat automatically.

Does Mitosis occur in mature muscle tissue?

Even with age Mitosis continues. It is when mitosis ceases that the organism will die. Mitosis occurs only in eukaryotic cells (an organism whose cells contain complex structures enclosed within membranes. ), and the process varies in different species.The process of mitosis is fast and highly complex.

In animals, cytokinesis and mitosis may occur independently, such as in embryonic development. Errors in mitosis can either kill a cell through apoptosis or cause mutations that may lead to certain types of cancer.

If mitosis ceases, an organism will lose the first barrier against infections, such as cells of the immune system. Consequently, in absence of mitosis, the human body would be overrun by a legion of infectious diseases, or 'opportunistic' pathogens such as pseudomonas would assume control.

In terms of location, the pectinate muscle can be found in the atrium, while the trabeculae carnea can be found in the ventricles.

What process allows muscle cells to continue to release energy in the absence of sufficient oxygen?

When the muscle cells are deprived of oxygen, the cells produce ATP through the anaerobic fermentation. Glycolysis occurs in the cytoplasm and does not need oxygen. In the glycolysis pathway, two ATPs are produced as net products. Also, anaerobic fermentation occurs. The pyuvate is converted into lactic acid and regnerate NAD using this process.

What term is used in regards with the stiffening of muscles of a corpse usually used by police investigators in determining the estimate time of death?

Rigor mortis is one of the recognizable signs of death (Latin mors, mortis) that is caused by a chemical change in the muscles after death, causing the limbs of the corpse to become stiff (Latin rigor) and difficult to move or manipulate[1]

Do the lungs contains elastic muscle tissue to permit inhalation?

It actually contains smooth muscle tissue, and alveolar connective tissue. This connective tissue contains collagen fibers for flexibility and strength, and numerous elastic fibers that enable it to be stretched. Alveolar connective tissue is found in the skin and in most internal organs of vertebrates, where it allows the organs to expand, which is essential for the lungs.
