Pneumono-ultramicroscopic-silicovolcano-coniosis.

Yes, this is an actual word. What does it mean? Biology can be filled with words that sometimes seem incomprehensible. By "dissecting" these words into discrete units, even the most complex terms can be understood. To demonstrate this concept, let's begin by performing a biology word dissection on the word above.

To perform our word dissection, we'll need to proceed carefully.

First, we come to the prefix (pneu-), or (pneumo-) which means lung. Next, is ultra, meaning extreme, and microscopic, meaning small. Now we come to (silico-), which refers to silicon, and (volcano-) which refers to the mineral particles that make up a volcano. Then we have (coni-), a derivative of the Greek word konis meaning dust. Finally, we have the suffix (-osis) which means affected with. Now lets rebuild what we have dissected:

Considering the prefix (pneumo-) and the suffix (-osis), we can determine that the lungs are affected with something. But what? Breaking down the rest of the terms we get extremely small (ultramicroscopic) silicon (silico-) and volcanic (volcano-) dust (coni-) particles. Thus, pneumonoultramicroscopicsilicovolcanoconiosis is a disease of the lungs resulting from the inhalation of very fine silicate or quartz dust. That wasn't so difficult, now was it?

Biology Terms

Now that we've honed our dissection skills, let's try some frequently used biology terms.

For instance:

Arthritis
(Arth-) refers to joints and (-itis) means inflammation. Arthritis is the inflammation of a joint(s).

Bacteriostasis
(Bacterio-) refers to bacteria and (-stasis) means a slowing or stoppage of motion or activity. Bacteriostasis is the slowing down of bacterial growth.

Dactylogram
(Dactyl-) refers to a digit such as a finger or toe and (-gram) refers to a written record.

A dactylogram is another name for a fingerprint.

Epicardium
(Epi-) means upper or outermost and (-cardium) refers to the heart. Epicardium is the outer layer of the heart wall. It is also known as visceral pericardium as it forms the inner layer of the pericardium.

Erythrocyte
(Erythro-) means red and (-cyte) means cell. Erythrocytes are red blood cells.

Okay, let's move on to more difficult words. For instance:

Electroencephalogram
Dissecting, we have (electro-), pertaining to electricity, (encephal-) meaning brain, and (-gram) meaning record. Together we have an electric brain record or EEG. Thus, we have a record of brain wave activity using electrical contacts.

Hemangioma
(Hem-) refers to blood, (angio-) means vessel, and (-oma) refers to an abnormal growth, cyst, or tumor. Hemangioma is a type of cancer consisting primarily of newly formed blood vessels.

Schizophrenia
Individuals with this disorder suffer from delusions and hallucinations. (Schis-) means split and (phren-) means mind.

Thermoacidophiles
These are Archaeans that live in extremely hot and acidic environments. (Therm-) means heat, next you have (-acid), and finally (phil-) means love. Together we have heat and acid lovers.

Once you understand the commonly used prefixes and suffixes, obtuse words are a piece of cake!

Now that you know how to apply the word dissection technique, I'm sure you'll be able to determine the meaning of the word thigmotropism (thigmo - tropism).
