Weboptic tract The part of the nerve pathway for visual impulses lying between the OPTIC CHIASMA and the first set of connections ( SYNAPSES) in the brain—the lateral geniculate … WebThe optic tract grows from the retina to the optic tectum. Because dorsal and ventral are inverted in the anterior head region, the tracts grow at first toward the ventral side, to meet in the midline to form a chiasma. Since the optic tectum lies on the dorsal midbrain, each tract then continues dorsally to the contralateral optic tectum. ...

WebOptic nerves project posteriorly to form the optic chiasm and continue as the optic tract. Axons from the temporal hemiretinas (nasal visual hemifields) project posteriorly in the IPSILATERAL optic tract (because it's contingent on the retina).

A chiral center is defined as an atom in a molecule that is bonded to four different chemical species, allowing for optical isomerism. It is a stereocenter that holds a set of atoms (ligands) in space such that the structure may not be superimposed on its mirror immage.
WebIn neuroanatomy, the optic chiasm, or optic chiasma ( / ɒptɪk kaɪæzəm /; from Greek χίασμα 'crossing', from Ancient Greek χιάζω 'to mark with an X '), is the part of the brain where the optic nerves cross.
