What are antagonistic effectors quizlet?
Antagonistic Effector. Control by antagonistic effectors is described as push-pull, where the increasing activity of one effector is accompanied by decreasing activity of an antagonistic effector. Antagonistic- going against/opposite. Ex: Body Temp. Positive Feedback.
What are examples of antagonistic hormones?
Examples of Antagonistic Hormones
- Parathyroid hormone (PTH) and Calcitonin. Calcitonin and PTH are referred to as antagonistic hormones, as their actions are diametrically opposite.
- Glucagon and Insulin. Insulin and glucagon are antagonistic hormones.
How do antagonistic hormones maintain homeostasis?
The regulation of blood glucose levels (through negative feedback) exemplifies how antagonistic hormones help the endocrine system maintain homeostasis. Pancreatic islets, which are clumps of cells in the pancreas, comprise two types of cells: alpha cells and beta cells.
Why insulin and glucagon are called antagonistic hormones?
Assertion : Insulin is antagonistic to glucagon. Reason : It is an anabolic hormone. Assertion : Insulin is antagonistic to glucagon. Reason : It is an anabolic hormone….

What are effectors quizlet?
Definition of Effector. *An organ, cell or tissue that acts in response to a stimuli (muscle or gland)
What are antagonistic muscles?
In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.
What is antagonistic control?
In antagonistic control we find an input sequence that maximizes (or at least makes large) an objective that is minimized in typical control. Applications include designing inputs to attack a control system, worst-case analysis of a control system, and security assessment of a control system.
Which pair consists of antagonistic opposing hormones?
Insulin and glucagon make up an antagonistic hormone pair; the action of insulin is opposite that of glucagon.
What are insulin antagonists?
An insulin antagonist may be defined as any substance or firaction which can cither modify or combine with insulin to render it inactive, or counteract its effects in vivo or in vitro.
What is the following in an example of an effector?
Effectors are parts of the body – such as muscles and glands – that produce a response to a detected stimulus. For example: a muscle contracting to move an arm. muscle squeezing saliva from the salivary gland.
What is an effector What are two types of effectors quizlet?
What are two types of effectors? An effector causes an effect in response to directions from the nervous system. Types include muscles and glands.
What is a negative feedback loop give an example?
Negative feedback systems work to maintain relatively constant levels of output. For example, the body maintains its temperature, calorie consumption, blood pressure, pulse, and respiratory rate based on negative feedback loops.
What is an example of a negative feedback mechanism?
A typical example of a negative feedback mechanism in the human body is the regulation of body temperature via endotherms. When the body’s temperature rises above normal, the brain sends signals to various organs, including the skin, to release heat in the form of sweat.
What does antagonistic mean in nervous system?
a substance that blocks activity of a receptor, thus inhibiting the effects normally caused by endogenous ligands binding to that receptor.
Which of the following is not an example of antagonistic hormones?
Which of the following pairs of hormones are not antagonistic (having opposite effects) to each other? Explanation: Relaxin and Inhibin are not antagonistic and have different functions. Relaxin is secreted by the placenta and ovaries.
What is an antagonistic effect of a chemical interaction?
An antagonistic effect of a chemical interaction occurs when two or more chemicals combine to produce a chemical with a total effect that is less than the sum of the effects of each individual chemical.
What is the synergistic effect of a chemical interaction?
A synergistic effect of a chemical interaction occurs when two or more chemicals combine to produce a chemical with a total effect that is greater than the sum of the effects of each individual chemical. Moreover, a synergistic reaction or interaction occurs when two or more chemicals combine into a chemical with more than double the effect.
Do antipsychotic medications have antagonistic effects on dopamine levels in aquatic organisms?
The higher-potency antipsychotic medications exert more of this antagonistic effect, whereas those with a lower potency show less dopamine antagonism. An antagonistic effect was stated if the combination gave less inhibition (p < 0. It was found that D and Cd had antagonistic effect on each other in the aquatic environment.
What is an additive effect drug?
For additive effect drugs, the same concept occurs in that when two or more drugs are combined, the effect of the combination is the same as what would be expected from the sum of the effects of taking of each drug independently.
