What is extrinsic regulation?
What is extrinsic regulation?
Definition. Extrinsic Regulation: responses controlled by nervous or endocrine systems. These organ systems detect an environmental change and send an electrical signal (nervous system) or chemical messenger (endocrine system) to control or adjust the activities of another or many other systems simultaneously. Term.
What is the difference between intrinsic and extrinsic regulation of a homeostatic control system?
An intrinsic controlled system is inherent in an organ; the organ is capable of maintaining homeostasis within itself. For example, the heart can control its own heart rate. Extrinsic control systems (nervous and endocrine systems) exist outside of the organs they control; these systems can override intrinsic systems.
What is extrinsic control?
Extrinsic controls of the cardiovascular system include neuronal, humoral, reflex, and chemical regulatory mechanisms. These extrinsic controls regulate heart rate, myocardial contractility, and vascular smooth muscle to maintain cardiac output, blood flow distribution, and arterial blood pressure.
Which of the following organ systems are responsible for the preservation of homeostasis through extrinsic regulation?
The major function of the endocrine system is to maintain the body’s homeostasis.
What is an example of extrinsic control?
Extrinsic control systems (nervous and endocrine systems) exist outside of the organs they control; these systems can override intrinsic systems. For example, although the heart controls its own rate, a slamming door will prompt the nervous system to increase the heart rate externally.
Which of the following is an example of extrinsic regulation?
Which of the following is an example of extrinsic regulation? * Blood vessels release chemicals to increase platelet aggregation. * The brain maintains its own blood pressure by controlling the diameter of its blood vessels. * Tissues release chemicals to increase blood flow to their cells.
What are the intrinsic and extrinsic controls of the heart?
The heart has both intrinsic (situated within the heart) and extrinsic (originating outside the heart) regulation. Many myocardial cells have unique potential for spontaneous electrical activity (intrinsic rhythm). In normal heart, spontaneous electrical activity is limited to special region.
What is the intrinsic regulation of blood flow?
Tissues and organs within the body are able to intrinsically regulate, to varying degree, their own blood supply in order to meet their metabolic and functional needs. This is termed local or intrinsic regulation of blood flow. Several mechanisms are responsible for local blood flow regulation.
What systems are responsible for extrinsic control throughout the body?
Extrinsic. Most homeostatic systems are extrinsic: they are controlled from outside the body. Endocrine and nervous systems are the major control systems in higher animals. The nervous system depends on sensors in the skin or sensory organs to receive stimuli and transmit a message to the spinal cord or brain.
What is Introjected regulation?
Introjected regulation is considered to be a relatively controlling form of motivation in which behaviour is regulated by internal sanctions and/or pressures that are directed towards attaining reward (e.g., ego enhancement and pride) or avoiding punishment (e.g., guilt and shame) (Ryan & Deci, 2000).
What are extrinsic motivators?
Extrinsic motivation is reward-driven behavior. In extrinsic motivation, rewards or other incentives — like praise, fame, or money — are used as motivation for specific activities. Unlike intrinsic motivation, external factors drive this form of motivation. Being paid to do a job is an example of extrinsic motivation.
