Biol 212 Worksheet: Leader: Caleb I Course: Bio 212 Practice Exam V Instructor: Kukday Supplemental Instruction Iowa University Date: 4/30/2017 What is the main difference between a strong and a weak stimulus? A strong stimulus causes a large action potential, while a weak stimulus causes a small action potential. A strong stimulus causes relatively few action potentials, while a weak stimulus causes many action potentials. Different sensory cells are responsible for strong stimuli than for weak ones. Stronger stimuli generate a higher frequency of action potentials than weak ones. Which of the following receptors is incorrectly matched with the sensory stimuli they detect? Nociceptors distortion by pressure – Thermoreceptors change in temperature – Chemoreceptor presence of a specific molecule – Photoreceptors wavelengths of light – Which one of the following is not a part of the human ear? Cochlea Sclera Oval Window Stapes What part of the ear contains hair cells that detect pressure waves? Cochlea Ossicles Pinna
