Which feedback system structure provides output from the control center?

Which feedback system structure provides output from the control center?

Effector
Effector – a body structure that receives output from the control center and produces a response or effect that changes the controlled condition.

What is the control center in the feedback system?

The control center is the component in a feedback system that compares the value to the normal range. If the value deviates too much from the set point, then the control center activates an effector.

Which component serves as the control center?

Control Center: The hypothalamus controls a variety of effectors that respond to a decrease in body temperature. Effectors: There are several effectors controlled by the hypothalamus.

What is the component of a control system that provides the means for the control centers response?

effector. provides the means for the control center’s response (output) to the stimulus.

What are examples of positive feedback loops?

Examples of processes that utilise positive feedback loops include:

• Childbirth – stretching of uterine walls cause contractions that further stretch the walls (this continues until birthing occurs)
• Lactation – the child feeding stimulates milk production which causes further feeding (continues until baby stops feeding)

What are the three main components of a homeostatic control system?

Homeostatic control mechanisms have at least three interdependent components: a receptor, integrating center, and effector.

Which of the following is an example of a positive feedback control system?

Explanation: The only example of a positive feedback loop is labor contractions, since in that case, the output increases the original stimulus. In all of the other answer choices, the body is trying to maintain homeostasis by reversing the effect of the original stimulus.

What is the control center in childbirth?

The cervix contains stretch-sensitive cells (sensors) that monitor the degree of stretching. These nerve cells send messages to the brain (control center), which in turn causes the pituitary gland at the base of the brain to release the hormone oxytocin into the bloodstream.

What is the correct order of elements in a control system?

Justice ch1 test

Question	Answer

receptor	element of the control center that detects a change
anatomical position	forward

What are two positive feedback examples?

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.

What is an example of a positive feedback loop in the human body?

One example of biological positive feedback is at the onset of contractions in childbirth. When contraction occurs, oxytocin is released into the body stimulating more contractions. Thus, the result is an increased amplitude and frequency of contractions. Another example is during the process of blood clotting.

What are the components of a negative feedback system?

A negative feedback system has three basic components: a sensor, control center and an effector. ( Figure 1.3.2 a ). A sensor, also referred to a receptor, monitors a physiological value, which is then reported to the control center.

What is the goal of a feedback control system?

In a feedback control system, the goal is to control the output to a desired value and that value is referred as desired output. Other common terms are reference and setpoint. The object whose output you try to control is called the plant.

How is a modal closed in a feedback system?

This modal can be closed by pressing the Escape key or activating the close button. Discover the components of a feedback control system and how they interact with each other. Learn basic terminology by walking through examples that include driving a car manually and using cruise control.

What are the names of the components of a control system?

Other common terms are reference and setpoint. The object whose output you try to control is called the plant. The output of the plant is measured by the component called the sensor and the measured output is then compared to the desired output.
