Study Notes
Skull Structure
- The orbit encloses the eyeballs and supports the teeth of the upper and lower jaws.
Neurocranium Function
- The main function of the neurocranium is to protect the brain.
Neurocranium Composition
- The occipital bone is a part of the neurocranium.
Viscerocranium Function
- The main function of the viscerocranium is to form the facial skeleton.
Viscerocranium Composition
- The maxilla bone is a part of the viscerocranium.
Frontal Bone Function
- The frontal bone forms the forehead and has a slight depression called the glabella.
Orbital Structure
- The orbit is the bony socket that houses the eyeball and muscles that move the eyeball.
Temporal Bone Structure
- The temporal bone forms most of the upper lateral side of the skull.
Pterion Location
- The pterion is the area of junction of four bones (sphenoid, temporal, frontal, and parietal) located in the anterior part of the temporal fossa.
Temporal Fossa Structure
- The temporal fossa is the shallow space on the lateral side of the brain case above the level of the zygomatic arch.
Temporal Bone Composition
- The temporal bone is subdivided into several parts, including squamous portion, zygomatic process, mastoid portion, and petrous portion.
Infraorbital Foramen
- The infraorbital foramen is the opening for a sensory nerve that supplies the anterior face below the orbit.
Zygomatic Process
- The zygomatic process is the bony process formed by a short anterior temporal process of the zygomatic bone and zygomatic process of the temporal bone.
Nasal Conchae
- The nasal conchae are the 3 bony plates projecting from each lateral wall of the nasal cavity.
