Neurocranium

Definition

  • The part of the skull that houses the brain
  • Contains three teirs:
    1. anterior cranial fossa - contains the frontal lobes of the brain
    2. middle cranial fossa - contains the temporal lobes
    3. posterior cranial fossa - contains the cerebellum and brain stem

Sutures

  • Coronal
  • Lambdoidal
  • Saggital

Meninges

Cranial nerves

  • See Cranial nerves
  • name the cranial nerves, state where they originate from the CNS, where they exit from the cranial cavity and their general functions


describe the intracranial course of the arteries supplying the brain, name their main branches and state their areas of supply

Define the term "Circle of Willis" and state its functional significance

outline the distribution of the anterior, middle and posterior cerebral arteries to the cerebral cortex

outline the distribution of the "central arteries" to the brain

state the origin and intracranial location of the middle meningeal artery and its significance in intracranial haemorrhage.
