Protection of the Brain
    • Skull
    • Meninges
    • CSF
slide32
Ventricles of the Brain
    • Lateral Ventricles
slide36
Ventricles of the Brain
    • Lateral Ventricles
    • 3rd Ventricle
slide38
Ventricles of the Brain
    • Lateral Ventricles
    • 3rd Ventricle
slide39
Ventricles of the Brain
    • Lateral Ventricles
    • 3rd Ventricle
    • 4th Ventricle
slide42
Ventricles of the Brain
    • Lateral Ventricles
    • 3rd Ventricle
    • 4th Ventricle
      • The cerebral aqueduct links the 3rd and 4th ventricles
slide46
If the cerebral aqueduct were blocked:

CSF would build up in the lateral and 3rd ventricles

CSF would not be able to reach the subarachnoid space

Both

Neither

slide47

Correct!

  • If the cerebral aqueduct were blocked:

CSF would build up in the lateral and 3rd ventricles

CSF would not be able to reach the subarachnoid space

Both

Neither

slide51
Blood-Brain Barrier
    • Only lipid soluble substances can diffuse across capillary endothelium
slide52
Blood-Brain Barrier
    • Water soluble substances cross only by active or passive transport
      • selective
      • directional
slide53
Brain regions without a blood-brain barrier
    • portions of hypothalamus
    • pineal gland
    • choroid plexus
slide54
Organization of Neural Tissue
    • gray matter
      • arranged as nuclei; often around ventricles and cerebral aqueduct
slide57
Organization of Neural Tissue
    • gray matter
      • Arranged as nuclei, often around ventricles and cerebral aqueduct OR
      • As thin outer layer of cerebrum and cerebellum (cortex)
slide59
Organization of Neural Tissue
    • White matter
      • arranged as “tracts”
      • Found everywhere gray matter isn’t
