Study Notes
Bones of the Skull - Inferior View
-
Zygomatic Bone: Often referred to as the cheekbone, contributes to the lateral wall of the orbit.
-
Sphenoid Bone: A butterfly-shaped bone that connects various parts of the skull and houses the pituitary gland.
-
Vomer: Forms a significant part of the nasal septum, separating the left and right airways in the nasal cavity.
-
Occipital Condyle: Rounded projections located at the base of the skull, articulating with the first cervical vertebra to facilitate head movement.
-
Foramen Magnum: The large opening in the occipital bone allowing for the passage of the spinal cord into the skull.
-
Occipital Bone: The back and base of the skull, playing a key role in the structure and protection of the brain.
-
External Occipital Protuberance: A prominent bump on the back of the occipital bone, serving as an attachment point for ligaments and muscles.
-
Maxilla (Palatine process): Upper jaw bone that forms the hard palate’s anterior portion, facilitating chewing and speech.
-
Palatine Bone: L-shaped bone that forms part of the hard palate, the floor of the nasal cavity, and part of the orbit.
-
Choana: The openings behind the nose leading to the throat, important for airway passage and drainage.
-
Medial Pterygoid Plate: Part of the sphenoid bone, involved in the attachment of muscles for jaw movement.
-
Zygomatic Arch: The bony arch that forms the prominence of the cheek, created by the zygomatic and temporal bones.
-
Lateral Pterygoid Plate: Also part of the sphenoid bone, playing a role in the attachment of muscles that allow for jaw depression and forward movement.
-
Temporal Bone: Located at the sides and base of the skull, these bones house structures critical for hearing and balance.
-
Stylomastoid Foramen: A small opening between the mastoid and styloid processes, through which the facial nerve exits the skull.
-
Mastoid Process: A conical bony prominence located behind the ear, serving as an attachment point for neck muscles.
