16 gru 2014 · The anatomical course of the optic nerve describes the transmission of special sensory information from the retina of the eye to the primary visual cortex of the brain. It can be divided into extracranial (outside the cranial cavity) and intracranial components.
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.
17 maj 2024 · Learn the steps of the visual pathway of the eye from the retina to the brain, and the visual field defects that can result from lesions along the pathway
2 maj 2017 · The visual pathway is composed of four neuronal elements. Photoreceptors, bipolar cells, and retinal ganglion cells are found in the retina. Axons of ganglion cells pass through the optic nerve, optic chiasm, and optic tract.
23 sie 2023 · [Visual pathway diagram]The visual pathway begins with light entering the ocular bulb from the visual fields and being processed by the retina. Visual information is then passed on from the retina by the optic nerve (CN II) through the optic canal (not shown) to the optic chiasm in the middle cranial fossa.
Anatomy of the visual pathway. The visual pathway is made up of the retina, optic nerves, optic chiasma, optic tracts, lateral geniculate bodies, optic radiations and visual cortex (summarized in Fig. 1-66).
