This article describes the human visual system, which is representative of mammalian vision, and to a lesser extent the vertebrate visual system. System overview. This diagram linearly (unless otherwise mentioned) tracks the projections of all known structures that allow for vision to their relevant endpoints in the human brain.
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).
There are 12 major anatomy systems: Skeletal, Muscular, Cardiovascular, Digestive, Endocrine, Nervous, Respiratory, Immune/Lymphatic, Urinary, Female Reproductive, Male Reproductive, Integumentary. Select a system below to get started.
19 gru 2022 · Structure and Function. 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.
The human visual system can be regarded as consisting of two parts. The eyes act as image receptors which capture light and convert it into signals which are then transmit-ted to image processing centres in the brain.

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 electromagnetic energy spectrum ...
