Which bone, located at the base of the skull and forming part of the eye socket, is known as the sphenoid bone?
A
Mandible
B
Zygomatic bone
C
Maxilla
D
Sphenoid bone
Verified step by step guidance1
Understand the location and function of the sphenoid bone: It is a complex bone located at the base of the skull, forming part of the floor of the cranial cavity and contributing to the structure of the eye socket.
Compare the sphenoid bone to the other options provided: The mandible is the lower jawbone, the zygomatic bone forms the cheekbone, and the maxilla is the upper jawbone. None of these are located at the base of the skull or contribute to the eye socket.
Recognize the anatomical significance of the sphenoid bone: It serves as a central 'keystone' bone, connecting with multiple other bones in the skull, including the frontal, parietal, temporal, and occipital bones.
Identify the sphenoid bone's role in forming the eye socket: The sphenoid bone contributes to the posterior portion of the orbit (eye socket), specifically through its greater and lesser wings.
Conclude that the sphenoid bone is the correct answer based on its anatomical location and structural contributions to the skull and eye socket.
