PROBLEM: Passage: Figure 16.8 Pituitary Tumor The pituitary gland is located in the sella turcica of the sphenoid bone within the cranial floor, placing it immediately inferior to the optic chiasm. If the pituitary gland develops a tumor, it can press against the fibers crossing in the chiasm. Those fibers are conveying peripheral visual information to the opposite side of the brain, so the patient will experience "tunnel vision"meaning that only the central visual field will be perceived. Answer: pituitary gland

SOLUTION:
Which gland is located in the sella turcica of the sphenoid bone within the cranial floor?
