Which of the following parts of brain constitute the brain stem?

biology nervous system of man human nervous system the structure of brain the human brain

  1. Midbrain and hindbrain

  2. Hindbrain and forebrain

  3. Forebrain and midbrain

  4. forebrain only

Show answer
Correct Option: A
Explanation:

Brainstem connects the cerebrum to the spinal cord. It consists of the midbrain (mesencephelon), medulla oblongata and the pons (parts of the hind brain). It relays information between the cerebrum and the spinal cord.

So, the correct answer is 'Midbrain and hindbrain'

Involuntary action in the body is controlled by

biology nervous system of man human nervous system the structure of brain the human brain

  1. Medulla in fore brain

  2. Medulla in mid brain

  3. Medulla in hind brain

  4. Medulla in spinal cord

Show answer
Correct Option: C
Explanation:

The medulla oblongata is a cone shaped neuronal mass in the hindbrain which connects higher level of both brain and spinal cord. It serves in several functions of the autonomous nervous system (ANS) such as involuntary actions like heart rate, breathing, swallowing, sneezing and digestion by the sympathetic and parasympathetic response. 

So, the correct answer is option C.

Cerebrum is also known as cerebellum.

biology nervous system of man human nervous system the structure of brain the human brain

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Cerebrum is a part of forebrain and makes up about two third of the human brain, and consists of two cerebral hemispheres joined by a curved thick band of nerve fibres called corpus callosum whereas cerebellum is a part of hindbrain and is only 1/8th the size of the cerebrum and lies under occipital lobe, dorsal to brain stem.

Put a tick mark against the correct alternative in the following statements :
Balance of body is controlled by

biology nervous system of man human nervous system the structure of brain the human brain

  1. Spinal cord

  2. Cerebellum

  3. Cerebrum

  4. Medulla

Show answer
Correct Option: B
Explanation:

It's a lot smaller than the cerebrum at only 1/8 of its size It controls balance or equilibrium of the body.

So, the correct answer is 'Cerebellum'
