Certain cells in the retina respond differently to the direction in which objects move. To understand how cells in the retina respond to different visual stimuli, the activity of a retinal ganglion cell was measured while a square moved across its visual field. Which statement best explains the increases in voltage during the periodic spikes? A. Depolarization of a neuron past a threshold voltage causes sodium channels to close. B. Depolarization of a neuron past a threshold voltage causes sodium channels to open. C. Depolarization of a neuron past a threshold voltage causes potassium channels to close. D. Depolarization of a neuron past a threshold voltage causes potassium channels to open.

The transduction process of converting light into neural signals sent to the central nervous system involves which of these steps? A. Bipolar Cells collect signals from Rods and Cones. B. The Optic Nerve carries signals about light from the Lateral Geniculate Nuclues to the Retinal Ganglion Cells. C. Retinal Ganglion Cells relay information to Rods and Cones. D. Light that reaches the eyes passes first through the Retina which focuses that light onto the Cornea.
Each of the following statements is false. Correct each statement to make it true. a. Activation of rhodopsin depolarizes photoreceptors. b. Activated rhodopsin activates transducin which deactivates cGMP phosphodiesterase. c. Cyclic GMP binds sodium channels, keeping them open, leading to the depolarization of photoreceptor in light.
The dissociation of rhodopsin in the rods in response to light causes a.the Na+ channels to become blocked. b.the rods to secrete less neurotransmitter. c.the bipolar cells to become either stimulated or inhibited. d.all of these.
Hair cell vibrations that open and close ion channels in the membrane are the basis of which sensory process? a. hearing b. vision c. smell d. taste Which of the following is NOT associated with depression? a. Elevated angiotensin II b. Elevated glutamate c. Elevated glucocorticoids
This image is of the very back of the eye. Light would be coming in from the left towards the right side. WHich label indicates the photo receptor rod and cone cells? A. middle layer, red and green B. rods and cones are not in this image, they are much closer to the front of the eye ball C. far right side, purple and yellow D. far left side, gray
Which of the following are correct? Which one or more? a. Auditory fatigue is the increase in threshold after exposure to a loud sound. Auditory adaptation is a reduction in response of the auditory receptors to a sound over time followed by a steady state. b. The change in auditory thresholds is independent of the intensity, but dependent on the duration of the loud sound. c. Exposure to loud sounds is unable to damage the hair cells in the inner ear and therefore cannot lead to a permanent threshold shift. d. Auditory adaptation is the increase in threshold after exposure to a loud sound. Auditory fatigue is a reduction in response of the auditory receptors to a sound over time followed by a steady state.
Which of the following correctly describes receptors in the skin? Select one: O a. All receptor types are spread uniformly throughout dermal tissue. Ob.
