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.
How does the human body detect changes in its internal conditions?
Homeostasis. Regulation of the endocrine system.
What is the function of the cold receptor?
to detect stimulus
Which type of stimulus do mechanoreceptors detect?
Sound
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
How are stimulus and response related?
our senses will detect stimulus and send impulse into the integrating centre(brain) to interpret. the brain will produce appropriate response toward the stimulus to the effector. e.g when Telephone ring, the ears will detect the stimulus(sound) and the brain will produce the response to pick up the phone (copy from Yahoo answers)
What kind of stimulus can Krause's end bulbs detect?
They detect sensations of touch and low frequency vibration
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.
The level of sensory stimulus strength at which an individual can detect the stimulus at least 50 percent of the time is called?
an absolute threshold
The smallest intensity of a stimulus that you can detect 50 percent of the time is?
Absoulute threshold
A tap is used to?
A tap is used toA. cut internal threads.B. cut external threads.C. center punch before drilling.D. detect vibration.
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
