What does inhibition mean in biology?
Inhibitory signals are signals that keep other cells in check. For example, the growth hormone from the pituitary gland acts on other cells to stimulate cell division. If the growth hormone is not produced or the pituitary is damaged, the other cells won’t grow. The brain is another example of an organ that produces an inhibitory signal to keep other brain cells from dividing. Inhibitory signals are involved in the maintenance of the body’s internal environment and the prevention
What does inhibition mean in genetics?
Inhibition is a negative effect that suppresses or reduces an organism’s normal development or growth. As the term implies, an inhibited growth can be in the form of reduced cell growth, reduced cell division or reduced growth of an organism. Inhibition can be caused by any number of factors, ranging from a chemical or physical agent to a genetic mutation. Inhibition can occur before a species even begins its life cycle, for example in the case of embryonic development in humans.
What does inhibition mean in cell biology?
Inhibitory signals are part of the cell communication system that helps cells to be in the right place at the right time. Signaling pathways are often triggered by cell surface receptors, which send a signal to the cell nucleus to alter gene activity and regulate cell growth, division, and movement. These receptors are sensitive to the environment and receive information about the external world. A cell can be inhibited by other cells, by substances in its environment, or by contact with other cells or the extrace’
What is inhibition mean in biology?
The concept of inhibition in biology is linked with the idea that the nervous system is a mechanism for carrying out actions or movements. An action can be studied at different levels: at the level of the single cell, at the level of a group of cells, or at the level of the whole organism. Neurotransmitters are chemical messengers that are involved in the control of action at all these levels. They can either stimulate or inhibit the contraction of muscles and be responsible for the coordination among the actions
What is inhibition mean in molecular biology?
When a signal transduction pathway is activated, a specific enzyme is produced and begins a process. If the level of the enzyme is too high, the pathway will not proceed as it should. The enzyme that produces the enzyme may have an inhibitory effect on the pathway. Inhibition is the action of a protein that stops the action of another protein. The “off” switch for the pathway is usually the inhibitory protein, and when it is deactivated the pathway will continue to function.
