PRINTABLE VERSION Test 4 You scored 75.66 out of 108.99 Question 1 Your answer is CORRECT. Which is not a function of sensory receptor cells? A) To detect or receive stimuli from the external/internal environment. B) To transduce or convert stimuli from the external/internal environment into an action potential or into a release of neurotransmitter. C) To process and interpret stimuli from the environment. D) A, B, and C are all functions of sensory receptor cells. Question 2 Your answer is CORRECT. Which of the following statements about sensory receptor cells is false ? A) The type of stimulus a sensory receptor cell responds to depends on the type of membrane receptor proteins it possesses. B) Stimulation of a sensory receptor cell causes a change in its receptor potential. C) All sensory receptor cells can fire action potentials. D) All are true statements. Question 3 Your answer is CORRECT. Which of the following pairs is not correctly matched? A) Taste buds: chemoreceptors B) Rod cells: photoreceptor cells C) Mechanoreceptor: responds to movement D) Hearing: detection of sound involves mechanoreceptors in sensory cells of the ear E) All are correctly matched. Question 4 Your answer is CORRECT. Which of the following sensory pathways is correctly matched? 1) The movement of fluid through the vestibular canal and subsequent vibration of the basilar membrane causing the bending of hair cells. 2) Binding of a chemical by a sensory cell intiates a signal transduction response leading to the release of neurotransmitter. 3) Flexion of a muscle stimulates a sensory cell to form and transmit action potentials to the brain. 4) Light stimulates sensory cells in the retina causing them to not release inhibitory neurotransmitter. A) 1 this sensory pathway applies to stretch receptors B) 2 this sensory pathway applies to taste buds C) 3 this sensory pathway applies to vision D) 4 this sensory pathway applies to hearing

B) The lens does not need to accommodate and will maintain a thinner shape in bringing the object into focus. C) Cone cells of the fovea will hyperpolarize. D) Light will be focused on the fovea of the retina. E) None are false, all the above are true. Question 6 Your answer is CORRECT. Which statement is false about the protein-pigment complexes of photoreceptor cells? A) The light absorbing pigment is retinal and is formed from vitamin A. B)
