Question

Which of the following parts makes up the forebrain?
A. Diencephalon and Cerebrum
B. Diencephalon and Cerebellum
C. Diencephalon and Medulla
D. Diencephalon and Pons

Answer 1

Hint: There are three parts to the human brain, forebrain or prosencephalon, midbrain or mesencephalon, and hindbrain or rhombencephalon.

Complete answer: Forebrain also known as prosencephalon is a region important for vertebrates. It includes the Telencephalon which contains the cerebral hemispheres and the diencephalon containing the thalamus, hypothalamus, epithalamus, and subthalamus. The forebrain is responsible for processing information related to complex cognitive activities, sensory and associative function, and voluntary motor activities.
The cerebellum is also present in the hindbrain along with reticular formation and brain stem.
So, option (b) is incorrect.
The medulla oblongata is located in the lower part of the brain stem which is present in the hindbrain.
So, option (c) is also incorrect.
Pons is located above the medulla oblongata in the brain stem. Thereby this is also the part of the hindbrain.
So, option (d) is also incorrect.
Therefore the diencephalon along with the cerebrum makes up the forebrain.
So, the correct answer is “Option A”.

Additional Information:
Cerebrum is the main thought and control center located beneath the cerebral cortex. The cerebrum is composed of grey matter and white matter.
The diencephalon is the region that appears in the upper end of the brain stem situated between the cerebrum and the brain stem. The thalamus is associated with relaying information from the sensory organs to the cerebral cortex. Hypothalamus is the part of the forebrain which is responsible for controlling fear, thirst, sexual drive, and aggression.

Note:
The hindbrain consists of the medulla oblongata, the pons, and the cerebellum, which controls respiration and movement. The forebrain consists of two parts- diencephalon containing the thalamus, hypothalamus which regulates emotions and motivated behaviors. The second part is the telencephalon consisting of the cerebrum.
