Question

Draw a well labelled diagram of the human brain.

Answer 1

Hint: Human brain is a part of the central nervous system of the human body. The human brain is the central information processing part of the human body. It acts as the ‘command and control’ system of the human body.

Complete answer:

Now we will discuss the human brain in detail.
First of all the human brain is well protected by the bony box called skull, and also by the ballooning effect of the CSF present between the skull and the brain.
The brain has been divided in three major parts, that are as follows
> Forebrain
> Midbrain
> Hindbrain
So first let us discuss a little about the parts of forebrain:
> Cerebrum
> Thalamus
> Hypothalamus
Now we will see the functions they perform in brief:
Cerebrum contains the motor and sensory areas and the association areas (these are responsible for complex functions like intersensory associations)
Thalamus is the major coordinating centre for motor and sensory signalling.
Hypothalamus controls body temperature, hunger, urge of drinking.

Note:
Now let’s see the midbrain, it is located between the thalamus or hypothalamus of the forebrain and the pons of the hindbrain. Now about the hindbrain, it basically consists of pons, cerebellum and medulla oblongata.
Cerebellum is responsible for maintaining the balance and precision of the movement.
Medulla controls respiration, cardiovascular reflexes and gastric secretions through various centres.
