• What is coronal section?

  Cut in a vertical plane from the crown of the head down > frontal view

• What is horizontal section?

  Cut is along the horizon > dorsal view looking down on the brain from above

• What is saggital section?

  Cut lengthways, front to back > reveals medial view from the side

• In which 4 ways are the brain and spinal cord supported?

  1. Skull body vertebrae > protects brain + spinal cord
  2. Triple-layered set of membranes > meninges consisting of dura mater, arachnoid membrane, pia mater
  3. CSF cerebrospinal fluid > shocks and pressure changes
  4. Blood brain barrier > protects brain + spinal cord by limiting movement of chemicals from the rest of the body into CNS

• What is dura mater?

  A tough double layer of tissue, on the outermost layer

• What is arachnoid membrane?

  Middle, is a very thin sheet of delicate tissue that follows the brain's contours

• What is Pia mater?

  Inner layer, that is moderately tough tissue that clings to the brain's surface

• Which 3 cerebral arteries are there?

  1. Anterior cerebral artery: gives blood supply to the medial and dorsal parts of the cortex. 
  2. Middle cerebral artery: gives blood supply to the lateral surface.
  3. Posterior cerebral artery: gives blood supply to the ventral and posterior surfaces. 

• To what leads a lesion in the anterior cerebral artery?

  It creates a very large chance that you will have a hemiplegia on the opposite side. Affects legs more than arms and hands > verlamming

• To what leads a lesion in the middle cerebral artery?

  It creates a very large chance that you will have a hemiplegia on the opposite side. Affects arms and hands more than legs. > verlamming 
  70% of the strokes happen in middle
