The correct option is
A Forebrain
The correct option is A
Explanation of the correct option:
- The forebrain is the largest part of the brain.
- The forebrain is composed of the cerebrum, corpus striatum, rhinencephalon, hypothalamus, epithalamus, thalamus, etc.
- The cerebrum is the centre for memory, intelligence, judgement, conscious thought, and other activities associated with thinking and feeling.
- Cerebrum also controls the perception of taste, smell, touch, pressure, pain, heat, and cold.
- The cerebrum controls our ability to speak and write.
Explanation of the incorrect options:
Option B:
- Midbrain is located between the diencephalon (Part of the forebrain) and the mid-region of the hindbrain.
- It is the smallest part of the human brain.
- It consists of two parts, namely- the tectum and cerebral peduncle.
- It coordinates the actions of different regions of the forebrain, hindbrain and midbrain.
- The tectum region of the midbrain coordinates the reflex actions related to visual perceptions and olfaction.
Option C:
- It is located at the posterior end of the midbrain.
- It consists of two parts- metencephalon and myelencephalon.
- Metencephalon has two parts -the cerebellum and pons.
- Mylencephalon is also known as the medulla oblongata.
- The cerebellum plays an important role in controlling body balance.
- Pons act as respiratory centers for the regulation of respiration.
- Medulla oblongata controls visceral reflexes such as sneezing, coughing, vomiting, secretion of saliva, etc.
Option D:
- Neurons are the structural and functional units of the nervous system.
- They are capable of sending and receiving nerve impulses.
- A typical neuron consists of a cell body and cellular processes called dendrons and axons.
Final answer: Cerebrum is the part of the forebrain.
