  • What are the two components of the skull? Which one is larger in infants?
  • Visceral component (viscerocranium) and Neural component (neurocranium)
  • Neurocranium is larger in infants
100
  • What bone(s) form the lateral border of the orbit?
  • Zygomatic bone
100
  • What muscles move the mandible and where do they attach?
  • Pterygoid muscles, attach to the medial and lateral pterygoid plates that project downward from the sphenoid bone
100
  • Where do we receive a dental block? What nerves is it affecting?
  • Mandibular foramen-inferior alveolar nerve initially and then mental nerve
100
  • True or false: caudal means toward the tail.

true

200
  • What are the bones associated with the viscerocranium?
  • Nasal bone, lacrimal bone, zygomatic bone, maxillae, inferior nasal conchae, unpaired vomer, and palatine bone
200
  • Where does an epidural hematoma occur and by damage to what artery?
  • It occurs at the pterion, and is caused by damage to the anterior branch of the middle meningeal artery. It occurs between the dura mater and inner table of the bone.
200

Which nerves runs though the internal acoustic meatus of the temporal bone?

  • CNVIII and CN VII
200
  • What does the “scalp” consist of?
  • Skin, connective tissue (dense-contains blood vessels and sensory nerve endings), aponeurotic layer (galea aponeurotica), loose connective tissue, periosteum
200
  • What are the three components of the brainstem?
  • Medulla, pons, and midbrain
300
  • What bones are associated with the neurocranium?
  • Frontal bone, parietal bone, ethmoid, sphenoid, temporal and occipital
300
  • What two structures are contained within the body of the sphenoid?
  • Hypophyseal fossa (sella turcica)-houses pituitary gland, and sphenoid sinus
300
  • What is the petrous portion a part of and what does it house?
  • Temporal bone, the inner ear which is essential for hearing (cochlea), balance (semicircular canals), and CNVIII (vestibulochohlear )
300
  • What are the components of the nervous system?
  • CNS, brain, spinal cord
300
  • Where does the anterior lobe of the cerebellum receive input form? Posterior lobe?
  • Spine, cerebral cortex
400
  • What is the function of emissary veins?
  • May pierce the skull and connect the veins of the scalp with diploic veins and internal venous sinuses
400
  • What are the foramina found in the orbit?
  • Optic canal, superior orbital fissure, inferior orbital fissure, infraorbital groove
400
  • What does the posterior cranial fossa contain? Middle cranial fossa? Anterior cranial fossa?
  • Cerebellum and brainstem
  • Temporal lobes
  • Frontal lobes
400
  • What are the components of the peripheral nervous system?
  • Nerves, ganglia
400
  • At what point was the vermis formed and what is its function?
  • Formed first, important for equilibrium and balance
500
  • True or false: the inner table is compact bone that attaches to the scalp.
  • False: the inner table is compact bone that attaches to the dura mater, the outer table is compact bone that attaches to the scalp.
500

What are the 5 sutures and what bones do they separate?

  • Sagittal suture-2 parietal bones
  • Coronal suture-frontal bone from parietal bones
  • Lambdoidal suture-occipital bone from parietal bones
  • Metopic suture-frontal bone from each other prior to fusion at about 6-8 months
  • Squamosal suture-parietal bone from squamous portion of temporal bone
500
  • What is the function of the crista galli?
  • It allows an attachment point for the dura mater
500
  • What are the different functions of the ascending reticular formation (RAS) vs. the descending reticular formation?
  • RAS regulates level of consciousness and awareness
  • The descending reticular formation drives respiration and cardiovascular reflexes, as well as maintaining muscle tone
500
  • The cerebellar peduncles consist of groups of axons that carry information back and forth between what?
  • Cerebellum and brainstem
