Prefix/Suffix Meaning/Derivation Example
-oid – G, appearance glenoid – glen – means socket (review); oid – having the appearance of. Put them together – appears like a socket. Remember the ball and socket joint of the shoulder. Re-read past lectures so our puzzle can come together.
Omo- G, scapula, shoulder omohyoid – a muscle at the front of the neck that consists of two bellies separated by an intermediate tendon. This name gives a huge clue. One end of the muscle attaches at the shoulder and the other attaches at the hyoid bone. The more words or parts of words you know, the better student and professional you will become. Omo- comes from the Greek word ‘omos’ which means shoulder. I hope you are very comfortable with medical terms by now. Some can be big, but your knowledge is becoming bigger than any word you cannot pronounce.
-otomy G, to open craniotomy– a surgical procedure that opens the cranium (the brain’s housing).
Para- G, beside paravertebral- beside the vertebra. This adjective can be used to describe nerves, tumors, punctures, injuries, etc. Knowing grammar helps also! Remember to use every honest angle you have. Sometimes simply knowing the part of speech a word can help get the correct answer on a test. One word can change the meaning of a question or response. (Paralegals work beside attorneys, doing research and other technical legal work.)
Super- L, over superficial – superficial veins can be felt and sometimes seen, through the skin. The word superficial describes and is thus an adjective. Superficial wounds are on the skin or immediately beneath it. Another usage is shallow, such as polite conversations about the weather. I like to get to know people deeply. The idea is that if you know a person’s challenges and triumphs, you might get to know the true person. I hope you have a few relationships that move beyond the superficial. (Have fun while you learn.)
Supra- L, above supraorbital- orbital has to do with the eye. Supraorbital is above the eye; Infraorbital – beneath the eye.
Sym- G, growing together symphises – the uniting of bones by a layer of cartilage. (Example- Pubic symphises) Syn- also means together, as in synergy.
Teres L, round ligamentum teres uteri– (noun) – this ligament is attached to the uterus on either side in front of and below the opening of the Fallopian tube, and passing through the inguinal canal to the labia majora. (Also called round ligament of the uterus.)
Trans- L, across transfusion – Break it down – across and bringing together? Of course we have all heard of blood transfusions. But if you had never heard of it, you can break the word into parts. A transfusion is a process in which whole blood or blood components are taken from one person and delivered intravenously to another person. We will discuss transfusions in detail during the series on blood.
Tome- G, cutting dermatome – an instrument used for cutting thin slices of skin
Tuber- L, swelling tubercle – a round nodule on a bone. (We have seen this in detail on a previous lecture.)
Lecture 10 will consist of the final five prefixes or suffixes. There are many more to cover, but with the 80 that we have covered so far, I feel comfortable picking up the pace. You are no longer a novice. You should feel comfortable having an anatomical discussion with anyone.
