what are effectors in homeostasis?
3507
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.

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

Thus, stress is defined as a state in which homeostasis is actually threatened or perceived to be so; homeostasis is re-established by a complex repertoire of behavioral and physiological adaptive responses of the organism. The development of concepts of homeostasis and stress is summarized in Box 1.

The ANS helps to maintain homeostasis (internal stability and balance) through the coordination of various activities such as hormone secretion, circulation, respiration, digestion and excretion.

An effector acts in special ways in response to a nerve impulse. In humans, effectors may either be muscles, which contract in response to neural stimuli, or glands, which produce secretions.

Homeostasis is generally maintained by a negative feedback loop that includes a stimulus, sensor, control center, and effector. Negative feedback serves to reduce an excessive response and to keep a variable within the normal range. Negative feedback loops control body temperature and the blood glucose level.

Homeostatic imbalance occurs when cells in the body experience a deficiency, such as nutritional deficiencies resulting from an unhealthy diet or when cells are exposed to toxins. ... 3) Environmental influences such as exposure to toxins.

Within the process of homeostasis the nervous system detects and responds to adaptions within the body's internal and external environments by sending fast electrical impulses through nerves to the brain which instructs an effector and enables them to react quickly and return the body to a state of equilibrium.

the most accurate definition of homeostasis. The ability of an organism to maintain relatively constant internal conditions despite variability in external conditions.

The biological definition of homeostasis is “the tendency of an organism or cell to regulate its internal environment and maintain equilibrium, usually by a system of feedback controls, so as to stabilize health and functioning”. Generally, the body is in homeostasis when its needs are met and its functioning properly.

The nervous system maintains homeostasis by controlling and regulating the other parts of the body. A deviation from a normal set point acts as a stimulus to a receptor, which sends nerve impulses to a regulating center in the brain.

a. A homeostatic control reflex occurs in response to a stimulus that is produced from a sequence of events in the body. This reflex likely controls a variable throughout the body, where as a local homeostatic response occurs only in the area of the stimulus. 10.

Homeostatic control A negative feedback mechanism is an important type of control that is found in homeostasis. A negative feedback control system responds when conditions change from the ideal or set point and returns conditions to this set point. There is a continuous cycle of events in negative feedback.

How it aids in homeostasis: The Reproductive System doesn't do much to aid in the homeostasis of an organism; instead, it aids in the maintenance of the species itself. However, sex hormones do affect organs in the body. If there is a hormone imbalance in the body, it may lead to various disorders.

What do unicellular organisms do to maintain homeostasis? They maintain homeostasis by growing, responding to the environment, transforming energy, and reproducing.

Homeostasis and Stress Stress is a key factor in the disruption of homeostatic functional equilibrium, in that living systems are in a constant state of flux, incessantly adjusting to the effects of environmental stimuli, both external and internal (emotional, chemical or physical).
