Where a stimulus produces a response that opposes or negates the original stimulus?
Effector: a cell or organ that responds to the commands of the control center and whose activity either opposes or enhances the stimulus.
Which of the following results in a response that opposes the original stimulus?
Negative feedback results in a response that opposes that of the original deviation from normal. Blood clotting is an example of positive feedback since the action of the effector amplifies that of the stimulus.
What stimulus produces a response?
positive feedback a stimulus produces a response that amplifies or enhances the original stimulus.
When the response to a stimulus is to shut off the original stimulus?
Two Types of Feedback Loops: Negative and Positive. Negative feedback is a mechanism in which the effect of the response to the stimulus is to shut off the original stimulus or reduce its intensity. Negative feedback loops are the body’s most common mechanisms used to maintain homeostasis.
What is the cell or organ that directly carries out a response to a stimulus called?
What are the 3 types of stimuli?…What is the cell organ that directly carries out a response to a stimulus called?
| Front | Back |
|---|---|
| Structures within a cell that carry out specific functions for it are called | Organelles |
| A structure that carries out the body’s ultimate response to a stimulus is called an | Effector |
Which type of feedback continues the original stimulus?
Positive feedback mechanisms
Positive feedback mechanisms control self-perpetuating events that can be out of control and do not require continuous adjustment. In positive feedback mechanisms, the original stimulus is promoted rather than negated. Positive feedback increases the deviation from an ideal normal value.
What is positive feedback give an example?
Positive feedback occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly. Some examples of positive feedback are contractions in child birth and the ripening of fruit; negative feedback examples include the regulation of blood glucose levels and osmoregulation.
Which type of feedback occurs when the original stimulus is opposed?
Negative feedback
The type of response determines what the feedback is called. Negative feedback occurs when the response to a stimulus reduces the original stimulus. Positive feedback occurs when the response to a stimulus increases the original stimulus.
What are the types of stimulus?
There are two main types of stimulus –the external stimulus and the internal stimulus.
What is the behavior for a stimulus?
In psychology, a stimulus is any object or event that elicits a sensory or behavioral response in an organism. In behavioral psychology (i.e., classical and operant conditioning), a stimulus constitutes the basis for behavior.
When a stimulus is reinforced to continue in the same direction?
A homeostatic system may also be controlled by positive feedback. The stimulus here is reinforced to continue in the same direction until a climactic event occurs (figure 1.14). Following the climactic event, the body again returns to homeostasis.
How is a positive feedback loop normally stopped?
In these cases, the positive feedback loop always ends with counter-signaling that suppresses the original stimulus. A good example of positive feedback involves the amplification of labor contractions. The contractions are initiated as the baby moves into position, stretching the cervix beyond its normal position.
