The ventricles

The ventricles

1. ·

   • 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.
