Vesicles and ventricles

• The neural canal is the lumen of the neural tube
• The primitive ventricles are cavitys developed in each primary vesicle
• The rhombencephalon becomes the fourth ventricle, which consist of the metacoel of the metencephalon and the myocoel of the myelencephalon
• The lumen of the mesencephalon is known as the aqueduct of sylvius or mesocoel
• That of the diencephalon is known as the third ventricle or diocoel
• The lumina of the cerebral hemispheres of the telencephalon are the lateral ventricles or telocoel
• Name the lumen

  A) telocoel

  B) telocoel

  C) diocoel

  D) mesocoel

  E) Myeocoel

  
• The connection between the lumen of the spinal cord with that of the brain vesicles allows for cerebrospinal fluid to circulate between the brain and spinal cord
• The choroid plexus produces cerbrospinal fluid
