What it does
The brain is the control centre of the body, and different parts do different jobs. This page shows a simple side view of the brain, with the front of the head on the left. The big wrinkled cerebrum is split into four lobes (frontal, parietal, temporal and occipital). Underneath sit smaller parts that run the body without you thinking: the hypothalamus, the pituitary gland, the midbrain, the pons, the medulla and the cerebellum, with the spinal cord leading down from them. Tap any part to read what it does. To see how a quick message travels when the brain is skipped, try the reaction time; to see what a nerve signal is, open the nerve impulse lab.
Using it
- Pick a Level. Class 10 gives each part’s main jobs. Class 11 adds more detail: the motor and sensory areas, the speech areas, the hippocampus, the hormones of the pituitary, and more.
- Explore: tap a part. Its name, its division (forebrain, midbrain or hindbrain) and its jobs appear under the picture.
- Find the part: the page names an everyday action, such as “You ride a bicycle without falling over”. Tap the part that handles it. A right answer turns green; a wrong one turns red and the right part is shown. Your score and your run of right answers are kept until you leave the page.
- Fore, mid, hind: the parts are coloured by division, so you can see which belong together.
Worked example
Suppose the action is “You sneeze when dust gets up your nose.” Sneezing is not something you decide to do; it is an involuntary action, and those are run by the hindbrain. Tap the medulla (under the pons, just above the spinal cord): it turns green, and its card says it controls heartbeat, breathing, swallowing, coughing, sneezing and vomiting. If you had tapped the frontal lobe instead, it would turn red and the card would explain that the frontal lobe is for thinking and voluntary actions.
Where this fits in school
Class 10 science (control and coordination) covers the human brain, its main parts and their jobs, voluntary and involuntary actions, and how the brain and spinal cord are protected. Class 11 biology (neural control and coordination) adds the regions of the cerebrum, the limbic system and more about each part. This page is an independent learning aid. It is not made by or connected with NCERT, and it does not copy any textbook.
Questions
Is the pituitary part of the brain? It hangs from the brain and is controlled by the hypothalamus, but it is a gland: it makes hormones. The page lists it so you can see where it is.
Are the lobes really separate? No. They are areas of one cerebrum, joined to each other and to the other side. Many tasks, like reading aloud, use several areas at once.
Is anything saved? No. Your Find the part score goes when you leave the page.
Where the numbers come from
- The parts of the human brain and their main jobs: standard school biology, written by fibub in its own words.
- The picture is fibub's own simplified drawing, not to scale; deep parts are drawn on top of the side view so they can be tapped.
- Every action in Find the part was checked in the tests to point to a part that exists. Nothing you tap is stored or sent anywhere.
Standard scientific values, such as constants, atomic weights and melting points, are facts found in every textbook; we name where ours were checked. If you are an author or publisher and want a value, a credit or a table changed or removed, tell us and we will act quickly.
