3-EMT Ch.6 Axial Skeleton Flashcards

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.
