| Human Brain Diagram with Labels: Parts & Functions | Class 10 |
The human brain is the main control centre of the nervous system. It receives information from the body and environment, processes signals, and coordinates many activities of the body.
This article provides a simple explanation of the human brain diagram, major parts, and their functions, especially for Class 10 Biology students and exam revision.
Human Brain Diagram
A labelled diagram is one of the easiest ways to understand the organization of the human brain. Study the position of each major region along with its function.

Major Parts of the Human Brain
The brain can be broadly divided into the forebrain, midbrain, and hindbrain. Each region contains structures that perform specific functions.
1. Forebrain
The forebrain is involved in higher functions such as thinking, memory, reasoning, interpretation of sensory information, and voluntary activities.
Cerebrum
The cerebrum is the largest part of the human brain. It is associated with conscious activities, thinking, learning, memory, reasoning, intelligence, and interpretation of sensory information.
Thalamus
The thalamus acts as an important relay centre for sensory information travelling to the appropriate regions of the brain.
Hypothalamus
The hypothalamus helps regulate important homeostatic functions such as body temperature, hunger, thirst, and other internal conditions. It also has important connections with the endocrine system.
2. Midbrain
The midbrain forms a connection between parts of the forebrain and hindbrain and participates in the coordination of certain visual and auditory reflexes.
3. Hindbrain
The hindbrain includes the cerebellum, pons, and medulla oblongata. These structures are important for coordination, balance, and several involuntary functions.
Cerebellum
The cerebellum helps coordinate voluntary movements and maintain posture and balance.
Pons
The pons acts as a bridge between different parts of the brain and contributes to the coordination of neural activities, including functions related to breathing.
Medulla Oblongata
The medulla oblongata contains centres involved in several involuntary activities, including regulation of breathing, heartbeat, and other vital functions.
Brain Parts and Functions
| Brain Part | Major Function |
|---|---|
| Cerebrum | Thinking, memory, learning, reasoning and voluntary activities |
| Thalamus | Relay and processing centre for important sensory information |
| Hypothalamus | Homeostasis and regulation of several internal conditions |
| Midbrain | Coordinates certain visual and auditory reflexes |
| Cerebellum | Balance, posture and coordination of voluntary movements |
| Pons | Communication between brain regions and participation in respiratory control |
| Medulla oblongata | Regulation of several involuntary and vital activities |
Protection of the Human Brain
The brain is protected by the skull and by protective membranes called meninges. Cerebrospinal fluid also helps provide mechanical protection and supports the brain within the cranial cavity.
Brain and Nervous System
The brain works together with the spinal cord and peripheral nerves as part of the nervous system. Sensory information is transmitted to the central nervous system, where it is processed and appropriate responses are coordinated.
Human Brain: Important Class 10 Points
- The brain is the main control centre of the nervous system.
- The brain is protected by the skull.
- The major regions are forebrain, midbrain and hindbrain.
- The cerebrum is associated with higher mental functions and voluntary activities.
- The cerebellum helps maintain balance and coordinates voluntary movements.
- The medulla oblongata regulates several involuntary activities.
- The hypothalamus has an important role in maintaining homeostasis.
- The pons connects and coordinates activities between different brain regions.
Cerebrum → Thinking
Cerebellum → Balance & Coordination
Medulla → Involuntary Activities
Hypothalamus → Homeostasis
How to Draw a Human Brain Diagram in an Exam
- Draw the overall outline of the brain neatly.
- Mark the major regions clearly.
- Use straight label lines without crossing them unnecessarily.
- Write labels horizontally and legibly.
- Add a suitable title such as Human Brain.
- Revise the function of each labelled part.
Frequently Asked Questions
What is the main function of the human brain?
The brain receives and processes information and coordinates many voluntary and involuntary activities of the body.
Which part of the brain controls balance?
The cerebellum plays an important role in maintaining balance, posture and coordination of voluntary movements.
Which part of the brain controls involuntary activities?
The medulla oblongata contains centres involved in several important involuntary activities.
What are the three major regions of the brain?
The brain is commonly divided into the forebrain, midbrain and hindbrain for basic anatomical study.
What protects the brain?
The skull, meninges and cerebrospinal fluid provide protection and support for the brain.
Conclusion
The human brain is a highly organized control centre of the nervous system. For Class 10 Biology, focus on the labelled diagram and the functions of the cerebrum, cerebellum, hypothalamus, pons and medulla oblongata.
