Where is the optic chiasm located in relation to the pituitary gland?

Relevant anatomy The optic chiasm is positioned over the diaphragm sellae in 75–85% of patients. Clinically, the most important anatomical relationship of the chiasm is with the pituitary gland. The chiasm lies approximately 1 cm above the pituitary fossa (Fig. 11.7).Click to see full answer. In this manner, where is the optic chiasm?pt?k ka?æz?m/; Greek: χίασμα, “crossing”, from the Greek χιάζω, “to mark with an X”, after the Greek letter “Chi”), is the part of the brain where the optic nerves cross. It is located at the bottom of the brain immediately inferior to the hypothalamus.Subsequently, question is, where is the pituitary gland in relation to the optic nerve? The pituitary gland sits in a space called the pituitary sella, which is just a few centimeters behind the eyes. In order to see normally, we rely on our eyes to send information through cables (called the optic nerves) that travel back to the brain. In this way, what is the optic chiasm function? Optic chiasm provides a site for the crossing over or desiccation of optic nerve fibers so that contralateral half of the visual field is perceived and processed by the visual cortex. Optic chiasm is surrounded by the circle of Willis and derives its blood from the vessels forming this circle.What happens at the optic chiasm quizlet?1) Neurons in the LGN send their axons through optic radiations to the primary visual cortex or striate cortex. 2) At the optic chiasm, ganglion cell axons’ serving the inner halves of the retina (nasal sides) cross through the optic chiasm and ascend to the LGN on the opposite side of the brain.
