What is regulation and homeostasis?
Homeostasis refers to stability, balance, or equilibrium within a cell or the body. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is called homeostatic regulation.
What is the role of the effector in homeostatic regulation *?
An effector is any organ or tissue that receives information from the integrating center and acts to bring about the changes needed to maintain homeostasis. One example is the kidney, which retains water if blood pressure is too low.
What is homeostatic regulation and how is it physiologically important?
Homeostatic regulation is an essential metabolic process of the body that maintains internal, physical, and chemical balances of all organ systems of all living organisms. Homeostatic regulation provides the optimal control and production of biomolecules essential for the growth and development of the organism.
What detects a particular stimulus?
Sensory receptors can receive information from outside the body, as in touch receptors found in the skin or light receptors in the eye, as well as from inside the body, as in chemoreceptors and mechanoreceptors. When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction.
What diseases are caused by homeostatic imbalance?
Diseases that result from a homeostatic imbalance include heart failure and diabetes, but many more examples exist. Diabetes occurs when the control mechanism for insulin becomes imbalanced, either because there is a deficiency of insulin or because cells have become resistant to insulin.
Why is homeostatic regulation important in humans?
Homeostasis plays a major role in the proper functioning of the body. The endocrine system has a regulatory effect on other organ systems in the human body. In the muscular system, hormones adjust muscle metabolism, energy production, and growth.
Which type of receptor is stimulated by sound waves?
4.4. The transmission of sound waves through the ear results in audition. Sounds travel from the outer ear to mechanoreceptors in the inner ear that excite the auditory nerve [7]. The inner ear also hosts vestibular mechanoreceptors that excite the vestibular neurons of the auditory nerve.

What are the three parts of homeostatic regulation?
Adjustment of physiological systems within the body is called homeostatic regulation, which involves three parts or mechanisms: (1) the receptor, (2) the control center, and (3) the effector. The receptor receives information that something in the environment is changing.
What are the mechanisms that control homeostasis in the body?
Homeostatic regulation usually involves A receptor, a control center, and an effector The mechanisms that control homeostasis are activated in response to A stimulus When the mechanisms that control homeostasis begin to fail… Our organs malfunction. We will become sick.
How does the effector work to maintain homeostasis?
The effector responds to the commands of the control center by either opposing or enhancing the stimulus. This ongoing process continually works to restore and maintain homeostasis.
How does the receptor respond to the control center?
The receptor receives information that something in the environment is changing. The control center or integration center receives and processes information from the receptor. The effector responds to the commands of the control center by either opposing or enhancing the stimulus.
