Located centrally at the base of the skull, it articulates with all other cranial bones and houses critical neurovascular structures. Its butterfly-shaped architecture and intricate relationships with surrounding structures make it essential for medical professionals to understand its detailed anatomy for surgical approaches and pathological considerations.

The human skull is a fascinating anatomical structure composed of multiple bones that protect the brain and sensory organs while facilitating essential functions like eating and breathing. This detailed anatomical diagram presents both frontal and lateral views of the skull, highlighting 29 distinct anatomical features.
