<span>Running releases painkilling chemicals in the brain called endorphins. Studies indicate that the level of endorphins in the blood increases during aerobic exercise causing a state called "runner's high" and reducing pain. Interestingly enough, drugs like morphine, heroin and opium have some similar characteristics to natural human endorphins,
Running produces these chemicals and they bind with opiod receptors in the nervious system to produce pain relief and mild euphoria during exercise. Running has been associated with increase endurance, injury resistance and the capacity to endure pain based on these characteristics.</span>
Tumors are caused due to uncontrolled growth of cells. Thus a mitosis inhibitor could be effective medication to treat tumor because it will inhibit cell proliferation and development of tumor.
Explanation:
- Tumors are mass of tissue that developed as a result of uncontrolled cell division.
- Cell division is a continuous process in our body and it replaces old and damaged cells with new one.
- But in case of tumors the cell division takes place in uncontrollable manner and continues to add cells to the tissue while the cell death do not take place.
- Ultimately an unwanted overgrown mass of cell develops that hinders with the normal functioning of the body.
- Tumor are classified as benign tumor and malignant tumors.
- Both these tumors need to be treated as they develop as an unwanted hindrance to the body metabolism.
- The best way to check the growth of tumor is to inhibit the cell division in the tumor tissue.
- Thus a mitotic inhibitor which will inhibit mitosis could be a good medication for treatment of tumors.
THis is absolutely false. It is often an action of hypermobility of the joints that helps to produce the limber effect that we see which is often termed as someone being double jointed while in fact they are singularly jointed not double jointed.
