About This Quiz

2.

Name the sinus
- Frontal
- Ethmoid
- Sphenoid
- Maxillary
Correct Answer

A. Frontal

Explanation

The correct answer is "Frontal" because it is one of the four main sinuses found in the human skull. The frontal sinus is located in the forehead, just above the eyebrows. It is a paired sinus, meaning there is one on each side of the forehead. The frontal sinus helps to lighten the weight of the skull and also plays a role in producing mucus that helps to moisten and protect the nasal passages.

Name the View
- Open mouth Waters
- Modified waters
- Waters
- Modified Townes
Correct Answer

A. Open mouth Waters

Explanation

The correct answer is "Open mouth Waters" because it is a specific type of radiographic view used to visualize the maxillary sinuses. It involves tilting the patient's head back so that the mouth is open, allowing for better visualization of the maxillary sinuses. This view is commonly used in dental and maxillofacial imaging to assess sinus pathology or to aid in the placement of dental implants in the posterior maxilla.

Explanation

The arrow is pointing to the Sella turcica. The Sella turcica is a depression in the sphenoid bone of the skull, located in the middle cranial fossa. It houses the pituitary gland and is shaped like a saddle, hence the name "Sella turcica" which means "Turkish saddle" in Latin.

Explanation

The arrow in the image is pointing to the posterior clinoid process. The posterior clinoid process is a bony projection located at the back of the sella turcica, which is a depression in the sphenoid bone of the skull. The posterior clinoid process serves as an attachment point for various structures, including the tentorium cerebelli, a fold of dura mater that separates the cerebrum from the cerebellum.
