Visual Pathway Anatomy

Click on a label to display the definition. The nerve fibers of the retina representing the axons of the ganglion cells collect together at the optic disc before passing out of the eye through the orbital bones and into the brain via the optic nerve the second cranial nerve.

At the chiasm fibres from the nasal medial half of each retina cross over to the contralateral optic tract while fibres from the temporal lateral halves remain ipsilateral.

Visual pathway anatomy. Gross anatomy below the visual pathway is. The visual system transmits visual information from the retina within the eyes to the primary visual cortex of the occipital lobe as well as the pretectal nuclei and superior colliculi of the midbrain. Intracranial the visual pathway within the middle cranial fossa the optic nerves from each eye unite to form the optic chiasm.

The visual pathway shows a precise retinotopical organization at all levels that gives the anatomical background for symptoms when some part of optic pathway is damaged. It begins at the retina and terminates at the primary visual cortex with several intercortical tracts. Choose from 500 different sets of visual pathways anatomy flashcards on quizlet.

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. Anatomy of visual pathway 1. Discover the worlds.
