Brain stem is made of

  1. Mid brain, pons, cerebellum

  2. Mid brain, pons, medulla oblongata

  3. Diencephalon, medulla oblongata, cerebellum

  4. Cerebellum, cerebrum, medulla oblongata
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The brain stem is anatomically composed of the midbrain, the pons, and the medulla oblongata. It connects the cerebrum to the spinal cord.

Read the following and find the correct statements
() Mid brain, pons varoli and medulla oblongata are together called brain stem
(b) Paracoels, are connected to the diacoel through the iter
(c) Regulation centres of heart beat, respiration, swallowing, cough etc are located in medulla oblongata 
(d) Cerebellum is also called gyroscope of the body

  1. a, b, c

  3. b, c, d

  4. a, b, d
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Statement (a) is correct (midbrain, pons, medulla). Statement (c) is correct (medulla controls vital functions). Statement (d) is correct (cerebellum maintains balance/gyroscope). Statement (b) is often debated in nomenclature, but (a, c, d) are clearly correct.

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

  1. Midbrain and hindbrain

  2. Hindbrain and forebrain

  3. Forebrain and midbrain

  4. forebrain only
Reveal answer Fill a bubble to check yourself
A Correct answer
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

  1. Medulla in fore brain

  2. Medulla in mid brain

  3. Medulla in hind brain

  4. Medulla in spinal cord
Reveal answer Fill a bubble to check yourself
C Correct answer
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.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
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.
