2023年5月1日 · The optic chiasm, or optic chiasma, is the part of the brain where the optic nerves cross and is therefore of primary importance to the visual pathway. It is located at the base of the brain inferior to the hypothalamus, and approximately 10 mm superior to the pituitary gland within the suprasellar cistern. It has important anatomical relationships with the third ventricle, …

In neuroanatomy, the optic chiasm, or optic chiasma (/ ɒ p t ɪ k k aɪ æ z əm /; from Greek χίασμα 'crossing', from Ancient Greek χιάζω 'to mark with an X'), is the part of the brain where the optic nerves cross.

2024年10月9日 · The optic chiasm, or optic chiasma, is an X-shaped structure at the base of the brain. The left and right eye’s optic nerves intersect here, combining visual information before moving further down the visual pathway to the brain.

2023年10月30日 · The optic chiasm is located at the base of the brain, just anterior and superior to the location of the pituitary gland. It is formed by merging fibers from the optic nerves. The optic chiasm contributes in conveying visual information from the eye to the cortex.

2024年9月30日 · By allowing information from both eyes to be processed by both hemispheres of the brain, the optic chiasm enables stereoscopic vision – our ability to perceive depth and see in three dimensions. This is why we have two eyes facing forward rather than on the sides of our head like many other animals.

2024年12月8日 · The optic chiasm is the x-shaped structure caused by the crossing of the optic nerves in the brain. Learn more about this structure and its diseases.

2021年5月11日 · The optic chiasm is located in the front part of the brain. It lies directly in front of the hypothalamus, the part of the brain that controls body temperature, hunger and mood. Long, threadlike nerve fibers, called axons, come together from …

2024年9月30日 · From the chiasm, the optic tract emerges as two distinct bundles, one on each side of the brain. These bundles curve around the cerebral peduncles, which are part of the midbrain, like ivy wrapping around a tree trunk.

2024年10月23日 · The optic chiasm or chiasma is the midline structure where the nasal (medial) fibers of the optic nerves decussate to continue posteriorly as the optic tracts. It lies in the chiasmatic cistern and along with the pituitary stalk, is completely encircled by the circle of Willis.

2023年5月1日 · The optic chiasm, or optic chiasma, is the part of the brain where the optic nerves cross and is therefore of primary importance to the visual pathway.
