- What are the stimuli for taste receptors?arrow_forwardWhich of the following statements about photoreceptors is true? A) There are more rod cells in the fovea of the eye, although overall there are more cones in the human eye. B) All of these options C) Photoreceptors are located near the front of the eye, in the cornea. D) There are two types of photoreceptors, rods and cones, that contain different photopigments.arrow_forwardHow does ear convert sound waves into neural impulses, which are sensed and processed by the brain enabling us to recognise a sound ?arrow_forward
- How many different odorants could a person distinguish if each odorant is bound by a single type of receptor and each receptor binds only a single odorant? How many if each odorant binds to two different odorant receptors? Three odorant receptors?arrow_forwardList the five major tastants Relate the relationship of taste to smell?arrow_forwardWhich of the following is an example of the process of transduction? Taste acceptance and rejection are processed in the hindbrain, while emotional reactions to taste are processed in forebrain. Different qualities of taste (sweet, salt, sour, bitter) activate different receptor cells in the taste buds. O A photon of light strikes a photopigment in a rod cell, changing the photopigment, which causes the close of ion channels, which reduces the rod's output of neurotransmitter. Molecules of alcohol evaporate from the surface of a liquid and get into your nasal passages.arrow_forward
- Include a 5-10 sentence explanation of how the sheep’s eye senses light and relays that data to the brain to interpret visual information. Some pieces to consider: What path does the light travel? What structures and pigments does it interact with? How does the signal travel to the brain? Where in the brain is the data processed? How is this different in the high light vs low light? How might the sheep’s vision differ from our own?arrow_forwardWhat are the similarities in how receptive fields are represented by the nervous system? What advantage does this give us with respect to senses?arrow_forwardList the five major tastants. Relate the relationship oftaste to smellarrow_forward

Explain in steps the process of tasting and the process of smellingarrow_forwardScent-free zones are important recommendations because some people are very sensitive to odorants. What is one reason that someone might be over-sensitive to odorants? higher threshold to activate the Golf cascade greater hyperpolarized resting potential in olfactory neurons reduced sensitivity of the Golf response lower threshold to activate the Golf cascadearrow_forward
