The ventricles

·
- Are a network of cavities that are distributed throughout the brain
  - They are lined with a specialized membrane called the choroid plexus, made up of glial cells called ependymal cells.Ependymal cells are designed to secrete cerebrospinal fluid.
    - - Therefore the main function of the ventricles is the production and distribution of cerebrospinal fluid.
  - Lateral Ventricles (Left and Right)
    - Both are C-shaped and divided into four parts.
      - Central part of the lateral ventricle
        It is located in the parietal lobe. The roof is formed by the corpus callosum and is covered by the upper surface of the thalamus and the tail of the caudate nucleus.
      - Anterior horn
        It is located in front of the ventricular foramen medially, it will be related to the septum Pelcidum, laterally to the caudate nucleus and inferior to the peak of the corpus callosum.
      - Temporal horn
        It extends throughout the entire temporal lobe. Relationship with the tapetum, tail of the caudate nuvleo and with the terminal stria.
      - Occipital horn
        It is related to the tapetum of the corpus callosum and the calcar avis.
  - third ventricle
    - cavity located in the midline between both thalamus and presenting a perforation corresponding to the internallamic adherence that maintains the two thalamus communicated. Receive and send spianal brain fluid.
  - Fourth ventricle
    - Cavity located forward between the bridge and the holongated medulla, has a relationship with the floor of the fourth cerebellar ventricule, cerebellum and peduncle.
      - Tiene tres foramenes: 1 foramen medio y dos aberturas laterales.
