The visual system includes the eyes, the connecting pathways through to the visual cortex and other parts of the brain (human system shown).
27 lip 2023 · The visual pathway refers to the anatomical structures responsible for the conversion of light energy into electrical action potentials that can be interpreted by the brain. It begins at the retina and terminates at the primary visual cortex (with several intercortical tracts).
Learning Objectives. 6.1.1 Describe the region of the electromagnetic spectrum that is perceived by our visual system, and the relative energy of photons at long and short wavelengths. 6.1.2 Describe the major parts of the eye and their role in focusing light to create a clear image. In this section, we will meet the range of the ...
The brain directs our body’s internal functions. It also integrates sensory impulses and information to form perceptions, thoughts, and memories. The brain gives us self-awareness and the ability to speak and move in the world.
19 gru 2022 · The visual system consists of 2 primary parallel pathways: optic and pupillary reflex pathways. [2] [3] Optic Pathway. The optic pathway begins in the retina, a complex structure of 10 layers, each serving a distinct function.
Vision is the special sense of sight that is based on the transduction of light stimuli received through the eyes. The eyes are located within either orbit in the skull. The bony orbits surround the eyeballs, protecting them and anchoring the soft tissues of the eye (Figure 25.1).
The visual system includes the eye and retina, the optic nerves, and the visual pathways within the brain, where multiple visual centers process information about different aspects (shape and form, color, motion) of visual stimuli.
