Anatomy: Skull & Bone Tissue Flashcards
Cranial Vault
The upper, domed portion of the skull that encases the brain.
Cranial Base
The bottom part of the skull that supports the brain and connects to the cervical spine.
Posterior Cranial Fossa
The shallow depression at the back of the skull that houses the cerebellum.
Middle Cranial Fossa
The central depression of the skull base that contains the temporal lobes and pituitary gland.
Anterior Cranial Fossa
The front part of the skull base that supports the frontal lobes of the brain.
Orbit
The bony cavity that contains the eye and its associated structures.
Nasal Cavity
The internal space of the nose that filters, warms, and humidifies air.
Oral Cavity
The mouth space that includes the tongue, teeth, and mucous membranes involved in digestion and speech.
Paranasal Sinuses
Air-filled spaces within the bones surrounding the nasal cavity that reduce weight and contribute to voice resonance.
Maxillary Sinus
The largest paranasal sinus located in the maxilla.
Sphenoid Sinus
A sinus located within the sphenoid bone behind the nasal cavity.
Frontal Sinus
The sinus located in the frontal bone above the eyes.
Frontal Bone
The bone forming the forehead and the upper part of the eye sockets.
Parietal Bone
The bones forming the sides and roof of the cranial cavity.
Supraorbital Margin
The upper rim of the eye socket.
Coronal Suture
The fibrous joint connecting the frontal bone to the parietal bones.
Supraorbital Foramen
A notch or hole in the supraorbital margin allowing for the passage of nerves and blood vessels.
Sagittal Suture
The joint between the left and right parietal bones.
Sphenoid Bone
A complex bone that forms part of the base of the skull and parts of the orbits
Foramen Ovale
An opening for the mandibular nerve
Foramen Spinosum
Lateral to the foramen ovale and is part of the greater wing of the sphenoid bone.
Optic Foramen
The opening for the optic nerve.
Pterygoid Process
Projections that serve as attachment points for muscles.
Greater Wing
The larger lateral portion of the sphenoid bone.
Lesser Wing
The smaller upper portion of the sphenoid bone.
Inferior Orbital Fissure
lower part of the orbit, specifically between the maxilla (upper jawbone) and the greater wing of the sphenoid bone.
Sella Turcica
The depression that houses the pituitary gland.
