The image shows a plain X-ray film of a lateral view of a skull. The face and front of the head are towards the left of the image and the back of the head and the vertebral column are towards the right of the image. The maxillary sinuses are paranasal air sinuses found in the structure of the maxilla bilaterally. They are located more anterior and superficial compared to the structure indicated by the arrow. However, the blue arrow indicates the pituitary fossa, a marked depression at the level of the sphenoid bone of the skull base, which houses the pituitary gland of the brain.

QuestionChoice
The image shows a plain X-ray film of a lateral view of a skull. The face and front of the head are towards the left of the image and the back of the head and the vertebral column are towards the right of the image. The odontoid peg is a bony projection of the C2 cranial vertebra (axis) which articulates with the atlas (C1 vertebra), forming the atlanto-axial joint which allows head rotation. The odontoid peg is found posterior and inferior in the midline compared to the structure indicated by the arrow. However, the blue arrow indicates the pituitary fossa, a marked depression at the level of the sphenoid bone of the skull base, which houses the pituitary gland of the brain.
