单词 | chiasm |
例句 | The right medial retina then projects across the midline through the optic chiasm. Anatomy and Physiology 2013-06-19T00:00:00Z The same axons extend from the eye to the brain through these two bundles of fibers, but the chiasm represents the border between peripheral and central. Anatomy and Physiology 2013-06-19T00:00:00Z A growth of the pituitary gland presses against the optic chiasm and interferes with signal transmission. Anatomy and Physiology 2013-06-19T00:00:00Z In addition, a very small number of RGC axons project from the optic chiasm to the suprachiasmatic nucleus of the hypothalamus. Anatomy and Physiology 2013-06-19T00:00:00Z If the pituitary gland develops a tumor, it can press against the fibers crossing in the chiasm. Anatomy and Physiology 2013-06-19T00:00:00Z Though the chiasm is helping to sort right and left visual information, superior and inferior visual information is maintained topographically in the visual pathway. Anatomy and Physiology 2013-06-19T00:00:00Z For example, the axons from the medial retina of the left eye cross over to the right side of the brain at the optic chiasm. Anatomy and Physiology 2013-06-19T00:00:00Z Extending from the optic chiasm, the axons of the visual system are referred to as the optic tract instead of the optic nerve. Anatomy and Physiology 2013-06-19T00:00:00Z The visual field is projected onto the two retinae, as described above, with sorting at the optic chiasm. Anatomy and Physiology 2013-06-19T00:00:00Z The axons that decussate in the chiasm are from the medial retinae of either eye, and therefore carry information from the peripheral visual field.
