B
Zygomatic bone
C
Maxilla
D
Frontal bone
Verified step by step guidance1
Step 1: Understand the concept of paranasal sinuses. Paranasal sinuses are air-filled spaces within certain bones of the skull that are lined with mucous membranes. They are connected to the nasal cavity and serve functions such as lightening the weight of the skull, humidifying and warming inhaled air, and enhancing voice resonance.
Step 2: Identify the bones that typically contain paranasal sinuses. The bones with paranasal sinuses include the frontal bone, ethmoid bone, sphenoid bone, and maxilla. These are collectively referred to as the 'sinus-containing bones.'
Step 3: Examine the options provided in the question. The options are: Ethmoid bone, Zygomatic bone, Maxilla, and Frontal bone. Compare each option to the list of bones known to contain paranasal sinuses.
Step 4: Recognize that the zygomatic bone does not contain paranasal sinuses. The zygomatic bone, also known as the cheekbone, is primarily involved in forming the lateral wall and floor of the orbit and does not have air-filled spaces connected to the nasal cavity.
Step 5: Conclude that the correct answer is the zygomatic bone, as it is the only bone listed that does not contain paranasal sinuses.
