Ventricles

• What are the ventricles of the brain filled with?

  Cerebrospinal fluid (CSF)
• What is the function of the ventricles in the brain?

  They communicate and circulate cerebrospinal fluid
• What are the main components of the ventricular system in the brain?

  • Lateral ventricles (1st & 2nd)
  • Third ventricle
  • Fourth ventricle
  • Cerebral aqueduct
  • Central canal
• How are the lateral ventricles shaped?

  “C”-shaped
• What connects the two lateral ventricles?

  The septum pellucidum
• Where is the third ventricle located?

  Surrounded by the diencephalon
• What shape is the fourth ventricle?

  Triangular
• What connects the third and fourth ventricles?

  The narrow cerebral aqueduct
• What is the role of the choroid plexus in the ventricles?

  Production of cerebrospinal fluid (CSF)
• How does the ventricular system connect to the spinal cord?

  It is continuous with the central canal
• How does cerebrospinal fluid (CSF) circulate throughout the CNS?

  Through the ventricular system and central canal
