What effect do the cells surrounding a normal cell have on the cell's growth and division?
A "normal" cell does not divide into daughter cells without taking account of its environment. If energy sources are low in a medium, it will start a signaling system to suspend or even arrest the processes of the cell cycle. And if it makes contact with other cells---determined by proteins on the cell surface which may interact (bind specifically or nonspecifically) with the surface of the other cell (or its cell surface proteins), it may send a signal to do many things. Possibilities include arresting or even initiating a cell cycle (mitosis), altering its cytoskeleton (formation/deformation of microfiilaments and microtubules) to make a better fit or increase cell motility, or even altering its basic metabolism to acquire nutrients in a different manner or from an open (apical or basal) surface. In many cells, there is an inhibition ("contact inhibition") of the cell cycle when cell surfaces contact each other, which is why in culture growth is restricted to monolayers. Not in all cases...cancer cells may form piles or multilayers of cells and not be contact-inhibited.
What else can I help you with?
Does cell division speed up when healing process nears completion?
The rate of cell division slows down,controls on growth are restored, and everything returns to normal.
Is masrurbation effect my growth or height?
No, masturbation does not have any effect on your growth or height. These factors are primarily determined by genetics and overall health. Masturbation is a normal and healthy sexual activity that does not have any negative impact on physical development.
How does mitosis affect the growth of tumor?
Mitosis is the process of cell division that allows for growth and repair in tissues, but in the case of tumors, it can lead to uncontrolled cell proliferation. Tumor cells often bypass the normal regulatory mechanisms that govern mitosis, resulting in rapid and unchecked division. This excessive mitotic activity contributes to tumor growth and can lead to the formation of masses that can invade surrounding tissues and metastasize to other parts of the body. Thus, understanding mitosis is crucial in developing treatments that target and inhibit tumor growth.
Cancer is uncontrolled cell growth called?
Cancer is characterized by uncontrolled cell growth, often referred to as "malignant" growth. This occurs when cells bypass the normal regulatory mechanisms that govern cell division and death, leading to the formation of tumors. These tumors can invade surrounding tissues and may spread to other parts of the body through a process called metastasis. Ultimately, this uncontrolled proliferation can disrupt normal bodily functions and pose serious health risks.
How are cancer cell growth differs from normal cell growth?
Cancer cell growth is uncontrolled, rapid, and does not respond to signals that typically regulate cell growth in normal cells. Normal cells have a regulated cell cycle with checks and balances to ensure controlled growth and division, whereas cancer cells have mutations that disrupt these regulatory mechanisms, allowing them to divide uncontrollably. Additionally, cancer cells can evade the body's immune system and can invade surrounding tissues or spread to distant organs, a process known as metastasis.
What are factors that can effect the normal body temperature?
illness, excerise, surrounding, stress
What is uncontrolled cell division in a multicelluar animal?
Uncontrolled cell division in a multicellular animal is known as cancer. It occurs when normal regulatory mechanisms that control cell growth and division are disrupted, allowing cells to multiply uncontrollably. This can lead to the formation of tumors and the invasion of surrounding tissues.
How does cancerous cell growth differ from normal cell growth, and can you explain the key distinctions between the two processes?
Cancerous cell growth is different from normal cell growth because cancer cells divide uncontrollably and can invade surrounding tissues. Normal cell growth is tightly regulated and stops when the body doesn't need more cells. The key distinctions between the two processes are the uncontrolled division of cancer cells, their ability to spread to other parts of the body, and their resistance to signals that would normally stop cell growth.
When cells are not responding to normal controls over growth and division they form a tissue mass known as?
tumor

What are proto-oncogenes and how do they differ from oncogenes?
Proto-oncogenes are normal genes that help regulate cell growth and division. When mutated or altered, they can become oncogenes, which promote uncontrolled cell growth and can lead to cancer. The main difference is that proto-oncogenes are normal genes that can become oncogenes through mutations.
When cells are not responding to normal controls over growth and division they form tissue mass known as?
When cells are not responding to normal controls over growth and division, they can form tissue masses known as tumors. Tumors can be either benign (not cancerous) or malignant (cancerous).
