Structure of hindbrain:
1. Hindbrain includes cerebellum, pons varolii and medulla oblongata.
2. Cerebellum is 11% of the total brain and is the second largest part of the brain.
3. It has three lobes, median vermis and lateral two cerebral hemispheres. It has outer grey and inner white matter.
4. Cerebral cortex shows sulci and gyri. The inner white matter of cerebellar medulla shows arbor vitae or branching tree-like processes.
5. Pons is the part that connects the two cerebral hemispheres. It has outer white and inner grey matter. Pons is made up of nerve fibres which form bridges between cerebrum and medulla oblongata.
6. Medulla oblongata is the last part of the hindbrain which continues further as a spinal cord. It has outer white and inner grey matter.
7. Its roof shows has posterior choroid plexus.
8. Eight pairs of cranial nerves arise from medulla oblongata.
