What is the meaning of vision and in which 3 steps can it be divided?

- objects in our environment reflect light, this light is translated into a mental image
- 3 steps:

1. An outer segment whose tip touches the pigment epithelium of the retina
2. An inner segment that contains the cell nucleus and organelles fo ATP and protein synthesis
3. A basal segment with a synaptic terminal that releases glutamate onto bipolar cells
