Pain, especially intense sensations, is unpleasant and sometimes difficult for a person to cope with. Nevertheless, pain detection is essential for human survival. Explain how pain detection is necessary for a person's survival

Which of the following statements is NOT true about the sensory systems?   Chemoreceptors are responsible for our senses of taste and smell   Mechanoreceptors respond to physical motion and changes in shape   A constant sensory stimulus may eventually lead to a decreased response thanks to sensory adaptation   All of our senses except for sight travel through the thalamus where they eventually go on to the primary sensory area of the cerebrum   Our sensory systems respond to external stimuli like sight and sound, but also internal stimuli like blood sugar levels or muscle contractions

When a person blinks, the part of the brain that interprets visual stimulation is suppressed. The spontaneous act of blinking is controlled by the area of the brain that controls involuntary movements such as breathing and blood pressure. To determine whether the lack of light or the act of blinking causes the suppression,  scientists had subjects close their eyes and then placed a bright flashing light in their mouth to stimulate the photoreceptors in the eyes through the palate. Visual stimulation was still suppressed.  So the photoreceptors in the retina were not stimulated even though they were exposed to light.  This study demonstrated that when a person blinks, it is the act of blinking and not the absence of light that causes the suppression of visual stimulation. In the diagram above, identify the part of the brain that is suppressed during blinking and the part of the brain that controls involuntary, spontaneous blinking. Select one: a. 3 and 8 b. 2 and 9 c. 5 and 6 d. 1…

What information does the pain receptor relay to the brain about stimuli BELOW threshold  1)The duration of the stimulation 2)The location of the stimulation 3)The membrane potential at the site of stimulation 4)none of the above
