  • What bones make up the skull region?
    The skull region consists of the cranium and the facial skeleton.
  • Name the four major sutures of the skull.
    • Sagittal suture
    • Coronal suture
    • Lambdoid suture
    • Squamous suture
  • List the four main sinuses in the skull.
    • Maxillary sinus
    • Frontal sinus
    • Ethmoidal sinus
    • Sphenoidal sinus
  • What is the function of the supraorbital foramen and which bone contains it?
    The supraorbital foramen allows passage of nerves and blood vessels above the orbit; it is located in the frontal bone.
  • Name four important features of the temporal bone.
    • External acoustic meatus
    • Mastoid process
    • Styloid process
    • Zygomatic process forming the zygomatic arch
  • What are the key features of the occipital bone?
    The foramen magnum allows spinal cord passage; occipital condyles articulate with the atlas vertebra.
  • Identify three important parts of the sphenoid bone.
    • Sella turcica
    • Greater wings
    • Lesser wings
  • What structures are part of the ethmoid bone?
    • Cribriform plates
    • Perpendicular plate
    • Superior and middle nasal conchae
    • Crista galli
  • What is the role of the alveolar processes in the maxillae and mandible?
    The alveolar processes contain the sockets for teeth in both the maxillae and mandible.
  • Name the four fontanels of the infant skull.
    • Anterior (frontal) fontanel
    • Posterior (lambdoidal) fontanel
    • Antero-lateral (sphenoidal) fontanel
    • Postero-lateral (mastoid) fontanel
  • What are the primary and secondary curvatures of the vertebral column?

    The atlas (C1) supports the skull and allows nodding; the axis (C2) has the dens which allows head rotation.
  • Name the three types of vertebrae in the spinal column.
    • Cervical vertebrae
    • Thoracic vertebrae
    • Lumbar vertebrae
  • What are the key features of the sacrum?
    The sacrum has the median sacral crest, sacral foramina, and the sacral canal.
