g the CNS. Phasic receptors adapt quickly to a stimulus. For that reason, they are good at detecting changes instead of constantly signaling the CNS. True False
Phasic receptors are sensory receptors that are fast acting in detecting changes in the strength of a particular stimulus or signal to the brain. They are fast adapting receptor cells that detect changes in the strength of a stimulus. Because of this fast adapting ability, they cannot be used by the CNS in constant signalling of stimulus. A different receptor called Tonic receptors are used by the brain for constant signalling because they are slow reacting cells are they continue to transmit signals to the CNS along as the stimulus remains and not to changes in the pressure or strength of the stimulus. Phasic receptors are so important in predicting the changes in the body fora given time and this helps to quantify how body can react to increase or release of a stimulus. because when stimulus is added it signals the brain for some time and it signals stops but when the stimulus is released, it also signals the brain detecting bodily deformations to various stimulus.
What is internal and external stimulus? What is an example of each?
Answer:A internal is situated or existing in the interior of something Example:No country should interfere in another country's internal<span> affairs
Answer:A external stimulus </span><span>is a detectable change in the internal or </span>external environment. Example: When a person sees a burger when hungry they s<span>tomach starts to growl</span>
