Verified step by step guidance

Begin by understanding the anatomy of the cranium, which is the part of the skull that encloses the brain.

Identify the key bones that form the base of the cranium. These include the sphenoid bone, temporal bone, ethmoid bone, and occipital bone.

Focus on the sphenoid bone, which is known for its distinctive butterfly shape. It is located at the base of the skull and plays a crucial role in forming the floor of the cranium.

Consider the anatomical features of the sphenoid bone, such as its wings and central body, which contribute to its butterfly-like appearance.

Review the functions of the sphenoid bone, including its role in providing structural support and housing important foramina for nerves and blood vessels.
