Visual Pathway Anatomy

Click on a label to display the definition. 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.

Visual Pathways

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.

Visual pathway anatomy. Intracranial the visual pathway within the middle cranial fossa the optic nerves from each eye unite to form the optic chiasm. Choose from 500 different sets of visual pathways anatomy flashcards on quizlet. Discover the worlds.

It begins at the retina and terminates at the primary visual cortex with several intercortical tracts. Anatomy of visual pathway 1. Visual feld retinal quadrent head eye are maintained in a fixed posture one eye is closed area seen by the open eye constitute the visual field of that eye visual field of the two eye overlap to a great extent on either side there is a small area which is seen only by eye of that side.

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. Learn visual pathways anatomy with free interactive flashcards. 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. Sivateja challa sssihms anatomy of visual pathway 2. The visual pathway describes the anatomical pathway by which electrical signals generated by the retina are sent to the brain fig.
