Answers (1)

The hindbrain consists the cerebellum, pons varolii, and medulla oblongata:

Cerebellum:

  • It is located at the base of the cerebellum.
  • The outer cerebellar cortex is made of grey matter and the inner cerebellar medulla is made of white matter.
  • The white matter has fibre tracts which connect the cerebellum with the medulla oblongata and the cerebrum.
  • Functions:
    • It coordinates muscular activity and the balance of the body.
    • The impulse of performing muscular activity originates in the cerebrum.
    • It modulates the voluntary movements initiated in the cerebrum.

Pons Varolii:

  • It is made of a thick bundle of white nerve fibres.
  • It lies above the medulla oblongata.
  • Functions:
    • It coordinates the two lobes of the cerebellum.
    • The pneumotaxic centre which controls breathing is located in the pons varolii.

Medulla oblongata:

  • It is located at the base of the skull.
  • It is conical in shape.
  • It continues behind the brain as the spinal cord.
  • Injury to the medulla oblongata results in death.
  • Functions:
    • It acts as a pathway and conducts impulses from the spinal cord to the brain.
    • It controls the activities of the internal organs, heartbeat and breathing.
