How are stimuli detected? -Answer By sensory receptors How does sensation occur? -Answer Electrochemical impulses arrive at cerebral cortex Sensory adaptation -Answer Process by which repeated, insignificant signals are filtered out What do photoreceptors do? -Answer Detect light (e.g. rods and cones in human eye) What do chemoreceptors do? -Answer Detect chemical signals (e.g. olfactory cells for smell, taste buds, internal detection of pH levels, etc.) What do mechanoreceptors do? -Answe...

Question 1 Not yet graded / 2.5 pts Your Answer: Describe how sensory information helps to sustain life. We need to be able to sense things like pain, hot or cold, etc for example: if I don't have the sensory imput for detecting hot or cold then I cannot sense when a pan is hot and I need to remove my hand from it. Sesnory information enables us to be able to recognize life harming things from the environment. Without these sensory inputs we would most certainly die or live a very short...
