  2. Grey matter - Wikipedia

    en.wikipedia.org/wiki/Grey_matter

    Grey matter in the spinal cord is known as the grey column which travels down the spinal cord distributed in three grey columns that are presented in an "H" shape. The forward-facing column is the anterior grey column , the rear-facing one is the posterior grey column and the interlinking one is the lateral grey column .

  3. Oligodendrocyte - Wikipedia

    en.wikipedia.org/wiki/Oligodendrocyte

    They are the most widespread cell lineage, including oligodendrocyte progenitor cells, pre-myelinating cells, and mature myelinating oligodendrocytes in the CNS white matter. [3] Non-myelinating oligodendrocytes are found in the grey matter surrounding and lying next to neuronal cell bodies. They are known as neuronal satellite cells, and their ...

  4. Development of the cerebral cortex - Wikipedia

    en.wikipedia.org/wiki/Development_of_the...

    The process occurs from embryonic day 10 to 17 in mice and between gestational weeks seven to 18 in humans. [2] The cortex is the outermost layer of the brain and consists primarily of gray matter, or neuronal cell bodies. Interior areas of the brain consist of myelinated axons and appear as white matter.

  5. Gyrification - Wikipedia

    en.wikipedia.org/wiki/Gyrification

    Gyrification is the process of forming the characteristic folds of the cerebral cortex. [1] The peak of such a fold is called a gyrus (pl. gyri), and its trough is called a sulcus (pl. sulci). The neurons of the cerebral cortex reside in a thin layer of gray matter, only 2–4 mm thick, at the surface of the brain. [2]

  6. Midbrain tegmentum - Wikipedia

    en.wikipedia.org/wiki/Midbrain_tegmentum

    The general structures of midbrain tegmentum include red nucleus and the periaqueductal grey matter. Nigrostriatal Pathway and Mesolimbic Pathway in the Dopaminergic System Unlike the midbrain tectum (which is a sensory structure located posteriorly), the midbrain tegmentum, which locates anteriorly, is related to a number of motor functions.

  7. Thalamus - Wikipedia

    en.wikipedia.org/wiki/Thalamus

    The thalamus (pl.: thalami; from Greek θάλαμος, "chamber") is a large mass of gray matter on the lateral walls of the third ventricle forming the dorsal part of the diencephalon (a division of the forebrain).

  8. Spinal interneuron - Wikipedia

    en.wikipedia.org/wiki/Spinal_interneuron

    In particular, the cell bodies of the spinal interneurons are found in the grey matter of the spinal cord, which also contains the motor neurons. In 1952, the grey matter of the cat's spinal cord was investigated, and it was shown to have ten distinct zones referred to as Rexed laminae. Eventually, the lamination pattern was also observed in ...

  9. Brain cell - Wikipedia

    en.wikipedia.org/wiki/Brain_cell

    Brain cells make up the functional tissue of the brain.The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges, blood vessels, and ducts.
