Hind Brain

HIND BRAIN

The hind brain consists of cerebellum and medulla oblongata.

  • Cerebellum
    • It is developed as prominent dorsal outgrowths from the medulla. Its anterior part projects forwardly into the cavity of optic lobes and is known as valvula cerebelli which is composed of cortex and medulla.
  • Medulla oblongata
    • The medulla oblongata is the posterior most part of the brain, which can be distinguished from the spinal cord. The medulla is divisible into columns of nerve fibres based on the types of information transmitted.

Spinal cord

  • In transverse section of spinal cord two regions are clearly distinct, i.e., central and peripheral. The central region is composed of numerous nerve cells hence looks grey and called grey matter, which roughly resembles a letter ‘Y’ or ‘X’. The cerebrospinal fluid is occupied by a central canal, which is filled with cerebrospinal fluid. The cerebrospinal fluid is secreted by the brain.
