28 Questions
What type of receptors in your skin detect the water temperature when you place your hand under the shower?
Thermoreceptors
What is the term for the electrical signals generated by the thermoreceptors based on the strength of the stimulus?
Graded potential
What triggers an electrical signal (action potential) that travels along nerves to the spinal cord?
Strong enough signal (crosses a threshold)
Where do the signals pass between neurons through chemical messengers, allowing the brain to consciously perceive the water temperature?
At the spinal cord and subsequently in the brain (thalamus, cerebral cortex)
What part of the brain allows for the conscious perception and processing of the water temperature?
Cerebral cortex
What is the final step in the pathway of nerve impulses when adjusting the shower temperature?
Signals are sent back from the brain through the spinal cord to activate muscles in the hand
