What is affector neurons?
these have one or more receptors that detect change in either the external or internal environment, information that is detected is transmitted as an electrical impulse to the CNS by the affector neuron.
What do baroreceptors respond to?
They detect the blood pressure of the internal environment and send the results to the CNS, where it will react in several different ways
Cells that detect conditions in the body's environment?
white blood cells
How is the grasshopper adapted to detect moving objects in the environment?
the answer to that is by vibration. in the wind.
How does the body detect heat?
Our bodies have nerve cells called thermoreceptors that measure temperature of our internal body and the external environment. When these nerve cells are stimulated by changes inside our bodies and in the world outside, they send their information to the brain, where it is mostly the job of the medulla oblongata to make changes to keep our internal body temperature constant.

What is the function and structure of the nervous system?
The function is to detect and to try to control! The structure is three fold. First, the ANS controls internal functions. Second, the CNS controls the nervous systems. Third, the PNS conveys information about the environment and "output" functions.
What do baroreceptors respond to?
They detect the blood pressure of the internal environment and send the results to the CNS, where it will react in several different ways
What is a way that a sensor can be used in a car?
Various ways. Infra Red sensors can be used for alarm systems to detect doors being opened or motion inside the vehicle. Sensors can be used in doors to detect when the door is opened, and trigger the internal light.
What does PIR detect?
detect any changes in the environment (noise level, vibration, temperature)
What is stimulus with examples?
A stimulus is a DETECTECTABLE change in the environment. e.g. light is a stimulus to an animal or plant if it can detect the light with a sensing eye or chemical

Detect changes of internal or external stimulus?

What are Perimeter systems?
Perimeter systems typically consist of magnetic contacts that detect the opening of doors and windows
What characteristics in living organisms helps them to detect their environment?
shelter
