Study Notes
Axial Skeleton
- The axial skeleton serves as the structural foundation for the body, providing attachment points for the limbs.
- Composed of four main components: skull, facial bones, thoracic cage, and vertebral column.
Cranium
- Formed by a fusion of several thick bones that create a protective shell for the brain above the eyes.
- Made up of four primary bones: occiput, temporal bones, parietal bones, and frontal bone.
Occiput
- Represents the posterior portion of the cranium, playing a critical role in the skull's structure.
Temporal Bones
- Located laterally on each side of the cranium; commonly known as the temples.
Parietal Bones
- Positioned between the temporal and occipital regions of the cranium, contributing to the skull's protective function.
Frontal Bone
- The bone that constitutes the forehead, providing a barrier for the frontal lobes of the brain.
Facial Bones
- Comprise 14 bones, forming the structure of the face and aiding in functions such as eating and breathing.
- Includes maxillae, zygomas, mandible, orbits, and small bones that create the bridge of the nose.
Maxillae
- Comprised of the upper, nonmovable jawbones, essential for facial structure and dental health.
Zygomas
- Known as the cheekbones, these bones contribute to facial contour and structure.
Mandible
- The lower jaw and only movable bone of the face, playing a crucial role in chewing and speaking.
Orbits
- Also known as eye sockets, formed by the zygomas, maxillae, and frontal bones; housing and protecting the eyes.
