Answer 2

Answer:

The human brain is divided into three parts: Forebrain, midbrain and hindbrain.

Midbrain:

→ It is also called as mesencephalon.

→ It is located between the thalamus of the forebrain and the pons of the hindbrain.

→ A canal called as cerebral aqueduct passes through the midbrain.

→ The dorsal portion consists of four round swellings called as the corpora quadrigemina.

→ One pair of superior colliculus is associated with vision while one pair of inferior collliculus is associated with hearing.

Hind Brain:

→ It is also called as rhombencephalon.

→ Hind brain consist of cerebellum, pons and medulla oblongata

Cerebellum:

• It is the second largest part of the brain.
• It consist of three lobes, a central vermis and two lateral cerebellar hemispheres.
• Cerebellum with the help of nerve fibres called as cerebellar peduncles are conected to the midbrain, medulla oblongata and pons.
• The cerebellum contains centres for maintaining balance and orientation of the body.

Pons:

• It consist of pontine nuclei, apneustic area and pneumotaxic area.
• Pontine nuclei relays signals for voluntary movements to the cerebellum.
• Pneumotaxic area and apneustic area control respiration.

Medulla oblongata:

• The medulla oblongata is connected to the spinal cord.
• Medulla contains centres which controls respiration, cardio-vascular reflexes and gastric secretions.
