LECTURE 2
Intended Learning Outcomes
By the end of this lecture, students will learn:
 Basic rules for remembering and forming scientific terms
Lecture content
• Structure of medical words.
• Word Roots
• Suffixes
• Prefixes
• Combining Forms
• Tumour terminology
• Singular and plural scientific terms
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
•
1.
There are three basic parts to medical terms:
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 —

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
= gland
adenoma
Lip/o
= fat
lipoma
My/o
= muscle
myoma
Lymph/o
= lymph tissue
lymphoma
Carcin/o
= malignant
carcinoma
Osteo/o
= bone
osteoma
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.
