Human vision and function/Part 1: Perception of objects/Introduction to anatomy & Physiology of the eye and visual pathway/revision questions

From the subject materials you have completed so far, consider the following:


 * 1) What do the prefixes  “ante” & “post” mean?
 * 2) So what do the terms anterior and posterior mean? Give examples of eye structures that are “anterior” and/or “posterior” to each other.
 * 3) Describe coronel, horizontal & sagittal sections.
 * 4) Why do we need additional “location” terminology for the eye, when describing  horizontal & sagittal sections?
 * 5) If an object absorbs ALL the wavelengths of light EXCEPT green, & reflects green from it’s surface, what colour will we perceive?
 * 6) What are the name of the photoreceptors that respond to coloured light?
 * 7) Which specific colours are they maximally receptive to? Why?
 * 8) Under which lighting conditions are these cells optimally active?
 * 9) Where are these cells found?
 * 10) What is the receptive field size in this region?
 * 11) What does this suggest, if we want to see something that’s coloured, as acutely (with as much definition), as possible?
 * 12) What are the name of the photoreceptors that respond to changes in light intensity?
 * 13) Under which lighting conditions are these cells optimally active?
 * 14) Where are these cells found?
 * 15) What is the receptive field size in this region?
 * 16) What does this suggest, if we want to see something that’s not coloured, as acutely (with as much definition), as possible?
