What is the Structure and Functions of Human Brain Class 10 Science
In this article, we will study the Structure and Functions of the Human Brain from the topic Control and Coordination out of Class 10 Science.
The Brain is the command center for the nervous system. It receives input from the sensory organs and sends output to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains
The brain is enclosed in the brain box (Cranium) and protected by a cerebrospinal fluid which acts as a shock absorber. It has several layers called MENINGES.
Spinal Cord: Spinal Cord is enclosed in the Vertebral column.
The human brain has three major parts:
(a) Fore-brain
(b) Mid Brain
(c) Hind Brain.
(a) Fore-brain (CEREBRUM) – Forebrain is the most specialized/complex part of the brain.
Functions
- Thinking part of the brain
2. Control the voluntary actions.
3. Memory storage – Store information
4. Centre associated with HUNGER
5. Receives sensory impulses from various body parts and integrates it
(b) Mid Brain
It connects the hind-brain with the fore-brain. It is the part of the central nervous system associated with vision, arousal (alertness), motor control, sleep/wake, hearing, and temperature regulation.
(c) Hind-Brain – Consists – Cerebellum, Medulla, and Pons
- Maintains Posture and Balance of the body
- Control body movement
- Controls involuntary actions eg – salivation, blood pressure, vomiting
- Regulation of respiration

Now let discuss the important areas of the Human Brain –
| Area | Location | Function |
| Premotor area | Frontal lobe | The highest centre for involuntary movements of muscles and ANS. |
| Motor area | Frontal lobe | Controls voluntary movements of the muscle |
| Broca’s area | Frontal lobe | Motor speech area |
| Somesthetic area | Parietal lobe | Perception of general sensation like pain, touch and temperature |
| Auditory area | Temporal lobe | Hearing |
| Olfactory area | Temporal lobe | Sense of smell |
| Wernicke’s area | Temporal lobe | Understanding speech written and spoken |
| Gustatory area | Parietal lobe | Sense of taste |
| Visual area | Occipital lobe | Sensation of light |
