Question

Write a short note on midbrain.

Answer 1

Midbrain is located between the thalamus region of the forebrain and pons region of the hindbrain. It helps in the relay of information from the hindbrain to the midbrain. The dorsal surface of midbrain consists of superior and inferior corpora bigemina and four round lobes called corpora quadrigemina. A canal known as cerebral aqueduct passes through the midbrain. The midbrain is concerned with the sense of sight and hearing.
