Question

Write short note on hindbrain.

Answer 1

Hindbrain consists of three regions pons, cerebellum, and medulla oblongata.

(i) Pons is a band of nerve fibres that lies between the medulla oblongata and midbrain. It helps to regulate several involuntary processes like respiration etc.

(ii) The cerebellum is a large and well-developed part of the hindbrain. It regulates motor movement which maintains posture, balance, coordination and speech.

(iii) The medulla oblongata is the posterior and simplest part of the brain. It is located beneath the cerebellum. Its lower end extends in the form of the spinal cord and leaves the skull through the foramen magnum.
