Ear Ossicles
When you learn about the ear, you will hear about the three bones in the middle ear. These are collectively called the ear ossicles. Each one of them has a unique name - the first one, the Malleus (commonly called 'hammer'), the Incus (the 'anvil') and the Stapes (the 'stirrup'). You would have learnt about how these are the smallest bones in the body, with the Stapes (last one) being the very smallest! This image shows you how small they really are in comparison to an individual's fingers!
Their function, in case you have forgotten it, is to amplify the sound vibrations and then pass these on to the inner ear! Of course, you knew it, didn't you? :P

Lobes of the Brain
The biggest part of the brain is the cerebrum. This helps in remembering, thinking, deciding, working out logic, planning etc. In terms of the tasks that it carries out, the cerebrum is said to be made up of four lobes, as shown in different colours in the figure alongside. A brief description of what task(s) each lobe is responsible for, follows.
- Frontal Lobe: involved in reasoning, planning, problem-solving (puzzles etc), emotions, speech etc.
- Parietal Lobe: involved in perceiving stimuli related to touch, pressure, temperature and pain.
- Temporal Lobe: involved in interpreting auditory stimuli (sounds and language), smell as well as in memory.
- Occipital Lobe: involved in vision.
Left Brain and Right Brain
The brain (and in particular, the cerebrum) is made up of two hemispheres: left and right. Each hemisphere is said to process different kind of information. For example, while the left hemisphere (or the "left brain") handles rational and sequential information, the right hemisphere (or the "right brain") is more intuitive and simultaneous. Individuals may have a tendency to be dominated by one of these sides of the brain, and therefore a person maybe referred to as right-brained or left-brained (that's assuming that he/she is not 'no-brained' ofcourse! :P). This would mean that the person whose left brain dominates his thinking processes would be logical in solving problems, while a person dominated by his right brain would be more intuitive and spontaneous in solving problems.
To read more about Left/Right brain characteristics, and also to find out whether you are right brained or left brained, visit the following sites:
The left brain and right brain work together and the information between these two get exchanged across a structure called the corpus callosum. Check out the image below, and try reading out the colour and not the word, and see the confusion your brain has to go through!!
