MCB 3209 Ch 10: nerve senses, touch and vision Study Guide Define : receptor types, receptor or generator potential, intensity-frequency coding, adaptation and lateral inhibition Know eye anatomy and be able to identify in a diagram retina, optic nerve, cornea, lens, pupil, and anterior cavity and vitreous chamber, rods and cones, amacrine, bipolar and horizontal cells and retinal pigment epithelium. Fovea is site of highest acuity (convergence vs no convergence of bipolar cells onto ganglion cells). In rods and cones, identify location of light sensitive pigments. Know light activates retinene of rhodopsin which is transduced to change in membrane voltage of rods, alteration (decrease) of release of inhibitory neurotransmitter, and subsequent activation of ganglion cells leading to optic nerve. Retina relay in brain occipital lobe in cerebrum (right visual field of both eyes goes to left visual cortex and left visual field of both eyes goes to right visual cortex). 1. T-F?
