Scientific Terminology In this course students will have to learn and remember extensive lists of complex terminology. While each discipline will have terminology that is particular to it, there are some common principles that apply to scientific terminology generally. The purpose of this course is to is to help students understand the origins of scientific terms and the way these terms are formulated in order to remember them better

Scientific Terminology Many of the words used in science have their origins in Greek and Latin words. If you know the meanings of the Greek and Latin roots of words, it makes them easier to remember. Similarly, as scientific words are often made up of several components, knowing these components, and in particular the ones that are commonly used in your discipline, will help you remember them or help you to work out their meaning.

Structure of Medical Terms There are three basic parts to medical terms: 1. Prefix (comes at the beginning and usually identifies some subdivision or part of the central meaning). 2.Root (usually the middle of the word and gives the main meaning) 3.Suffix (comes at the end and modifies the central meaning as to what or who is interacting with it or what is happening to it)

Prefixes A prefix is a word segment placed at the beginning of a word. A prefix helps to change or define the meaning of the word. It is often an adjective or a description and can contribute its particular meaning to a word Examples: anti Hyper poly

Prefixes

Roots The Root often indicates a place or an organ. Most root words are derived from Greek or Latin. Examples: cardi — gastr — nephr — pseudo

suffixes Found at the end of a word. It cannot be used alone, when added after a root it completes the word. Its function is to describe or explain the meaning or what is done to the root. Examples: ectomy — itis — ology —

suffixes

Term Prefix Root Suffix Meaning bradycardia Brady-(slow) Cardia (heart) Slowness of the heart hepatitis Hepat (liver) Itis (inflammation) Inflammation of the liver ophthalmitis Ophthalm (eye) Itis (inflammation) Inflammation of the eye polycystic Poly (many) Cyst (abnormal sac) Many-cysts sublingual Sub-(under) Lingua (longue) Under the tongue pharmacology Pharmakon (pharmacy Ology (study of ) Study of the effects of drugs

Compound Medical Terms & words Are medical terms which is formed of Two or more roots. Examples: Cardioangiography = heart and blood vessels radiography Cardiomyopathy = heart muscle disease Postcardiotomy = after heart removal

Tumor Terminology Adding -- oma (a swelling) to organ and tissue word roots names tumors. Not all tumors are malignant (cancerous). Many are benign (not life-threatening). Aden/o= glandadenoma Lip/o= fatlipoma My/o= musclemyoma Lymph/o= lymph tissuelymphoma Carcin/o= malignantcarcinoma Osteo/o= boneosteoma

Common word structures In scientific terminology there are often common ways of forming words. While there are inconsistencies to general rules. knowing these common ways of structuring words can help you both learn and recall them. For example, the following are typical word endings that indicate singular or plural.

Exercise What is this? levator labii superioris alaeque nasi.
