Study Notes
Nasal Anatomy
- The nasal septum consists of the ethmoid and vomer bones.
Paranasal Sinuses
- The temporal bone does not contain a paranasal sinus.
Sutures and Cranial Fossa
- The lambdoid suture is formed between the parietal and occipital bones.
- The middle cranial fossa is made up of the sphenoid, temporal, and parietal bones.
Bone Visibility
- The external auditory meatus is not visible in a sagittal view of the skull.
Zygomatic Arch
- The zygomatic arch is characterized by the temporal process of the zygomatic bone.
Parietal Bone Articulations
- The parietal bone articulates with the sphenoid, temporal, and occipital bones.
Temporal Bone
- The temporal bone is unique for forming the only joint with the mandible.
Alveolar Processes
- The maxilla and mandible contain alveolar processes.
Skeletal System Divisions
- The skeletal system is divided into axial and appendicular categories.
Cranium Components
- The cranium is composed of the parietal, temporal, frontal, and occipital bones.
Sutural Boundaries
- The squamous suture marks the interface between the temporal and parietal bones.
Cranial Nerves
- The olfactory nerve (CN I) passes through the olfactory foramina in the cribriform plates, surrounding the crista galli.
Ethmoid Bone Functions
- The ethmoidal sinuses serve to reduce the weight of the skull.
- The perpendicular plate of the ethmoid bone forms part of the nasal septum.
Ethmoid Bone Classification
- The ethmoid bone is classified as part of the axial skeleton.
Occipital Bone Anatomy
- The occipital bone is located at the posterior base of the cranium and houses the foramen magnum, where the spinal cord passes.
- Occipital condyles are critical for articulation with the vertebral column.
Sphenoid Bone Characteristics
- The sphenoid bone is located at the skull's floor and features the sella turcica, which is an area where the pituitary gland rests.
- The lesser wings of the sphenoid bone contain the optic canal.
Trigeminal Nerve Pathway
- The foramen rotundum conveys a branch of the trigeminal nerve (CN V).
Temporal Bone Features
- The zygomatic process contributes to the zygomatic arch, while the mandibular fossa articulates with the lower jaw.
- The external auditory meatus marks the opening of the ear canal, and the styloid process is a pointed spine landmark on the temporal bone.
