Study Notes

Frontal Bone

The frontal bone forms the forehead and upper eye sockets.
Contains the glabella, a smooth area between the eyes.

Ethmoid Bone

A critical structure in the skull, located between the eyes.
Contains the cribriform plate, which allows passage for olfactory nerves.
Features the crista galli, a ridge for attachment of meninges.
Includes the perpendicular plate, contributing to the nasal septum.
Houses ethmoidal air cells (sinus) that lighten the skull.
The superior and middle conchae are involved in air filtration and humidification.

Temporal Bone

Comprises several parts: squamous, petrous, and tympanic.
The mastoid process serves as a muscle attachment point.
Features the zygomatic process, contributing to the zygomatic arch.
Contains the external and internal acoustic meatus, which are pathways for sound and nerves.
The styloid process is a point for ligament and muscle attachment.
The mandibular fossa interacts with the jawbone.

Occipital Bone

Forms the back and base of the skull.
Contains occipital condyles, which articulate with the vertebrae.
The foramen magnum allows the spinal cord to connect with the brain.
Features internal and external occipital protuberances and nuchal lines for muscle attachment.

Sphenoid Bone

Central bone in the skull base, connects with multiple cranial bones.
Includes greater and lesser wings for structural support.
The optic canal transmits the optic nerve.
Contains the pterygoid processes with medial and lateral laminae for muscle attachment.
Features various foramina (ovale, rotundum, spinosum) that transmit nerves and blood vessels.

Zygomatic and Maxillary Bones

The zygomatic bone contributes to the cheek area and forms the zygomatic arch.
The maxillary bones form the upper jaw and contain the infraorbital foramen for nerve passage.

Palatine Bone

Forms part of the hard palate of the mouth.
Contains the greater palatine foramen for nerve and blood vessel passage.

Nasal Structures

Inferior nasal conchae and vomer bone are essential for nasal structure and function.
The nasal cavity is constituted by the ethmoid, frontal, and maxillary bones.

Mandible

Lower jaw composed of several features:
- Mental protuberance is the chin area.
- Alveolar process supports teeth.
- The mandibular notch and ramus are important for functionality.

Sutures and Landmarks

Coronal, lambdoid, squamosal, and sagittal sutures are fibrous joints between skull bones.
Anatomical landmarks include bregma, lambda, and pterion where multiple skull bones meet.

Fontanels

Flexible “soft spots” in a fetus' skull that allow for growth and passage during childbirth.

Dental Structure

Denotes types of teeth:
- Incisors: 2 per quadrant
- Canine: 1 per quadrant
- Pre-molars: 2 per quadrant
- Molars: 3 per quadrant

Additional Notes

Connections between bones are pivotal for structural integrity.
The skull houses important cavities and canals for sensory and neural function.
