Document Summary
Cns level- inhibitory neurons in the frontal lobe allows us to have scents fade away. Bitter takes very little to recognize because it is usually poisonous to us, sweet and salty are often craved because we need them for survival. More convex= more you can bend the light. Presbyopia- old age vision, loss of the ability to see a near object. Make flashcards for emotropia, hyperopia, myotropia, and astigmatism. Photoreceptors- rods and cones; adjacent to outer pigmented epithelial layer of retina. Bipolar cells- neurons that communicate with retinal ganglion cells. Ganglion cells- in most anterior region of retina; axons for the optic nerve. Right visual field is processed in the left occipital lobe. Temporal projects on the nasal (vice versa)they then pass each other and cross and everything is projected upside down and backward. Fovea centralis damage- loss of central vision aka macular degeneration. Auricle, external auditory canal, tympanic membrane, auditory ossicles, oval window, cochlea.
