Inferior View of Skull: Mandible Removed: Inferior View Of Skull Mandible Removed
The inferior view of the skull, with the mandible removed, provides a comprehensive perspective of the skull’s base. This view allows for the examination of various anatomical structures, including bony landmarks, foramina, muscle attachments, and more.
Bony Landmarks
- Occipital Condyles:Articulate with the first cervical vertebra (atlas) to allow for head movements.
- Foramen Magnum:Large opening in the occipital bone through which the spinal cord passes.
- Mastoid Processes:Projections of the temporal bone behind the ear, containing air cells and the mastoid antrum.
Foramina and Openings
- Jugular Foramen:Located at the base of the temporal bone, transmits the internal jugular vein, glossopharyngeal nerve (CN IX), vagus nerve (CN X), and accessory nerve (CN XI).
- Hypoglossal Canal:Located on the occipital bone, transmits the hypoglossal nerve (CN XII).
- Carotid Canal:Located in the temporal bone, transmits the internal carotid artery.
Muscle Attachments
- Digastric Groove:Groove on the temporal bone for the attachment of the digastric muscle.
- Styloid Process:Projection of the temporal bone for the attachment of muscles, including the stylohyoid, stylopharyngeus, and styloglossus.
- Jugular Process:Projection of the occipital bone for the attachment of the rectus capitis lateralis muscle.
Clinical Applications, Inferior view of skull mandible removed
- Cranial Nerve Assessment:Examination of the foramina on the inferior view of the skull can help assess the function of cranial nerves that pass through them.
- Skull Fracture Diagnosis:Fractures of the skull base can be visualized and assessed from this view.
- Surgical Planning:The inferior view of the skull is essential for planning surgical interventions involving the skull base, such as tumor removal or nerve decompression.
