OBJECTIVES

ID and recognize the parts of a medical termDefine commonly used parts of medical term Analyze and understand basic medical termsPractice pronunciation of medical terms

WARM UP Any guesses?

Pneumonoultramicroscopicsilicovolcanoconiosis

BIG IDEA QUESTIONWhat are the major parts of a term?

VET TERMINOLOGY• Every word has main parts• Like a sandwich! • Parts of the “sandwich”• Prefix- bread• Root- meat• Combining Vowel – lettuce• Combining form – tomato• Suffix- bread

VET TERMS• Used every day• Current Vocabulary• Based on terms of Greek and Latin origin • Or Eponyms: words formed from a person’s name

• Better understanding of Latin and Greek = better understanding of medical terminology

PREFIXES Found at the beginningIndicates a #, location, time, or statusTwo types

ContrastingDirectional

Example: Ab- means away from

ACTIVITY 1 sheet of lined paperFold it in half (long like a hot dog)Put the prefixes on one half, definition on the other

Studying graphic organizerPerform this exercise for both types of prefixes

IS THERE A PREFIX?Pneumonoultramicroscopicsilicovolcanoconiosis

ROOT WORDSGive essential meaning to the wordIs there a root?

Pneumonoultramicroscopicsilicovolcanoconiosis

COMBINING VOWELNormally singleUsually an o

I and E also usedAdded to root word to make it easier to pronounce

When 2+ root words are joined Not used when the suffix begins with a vowel

Example:Gastro/o + enter/o = gasteroenteritis

How many? Pneumonoultramicroscopicsilicovolcanoconiosis

COMBINING FORMSRoot word + a combining vowelUsually describes part of the body New words are created when prefixes + combining forms and suffixesExamples

PanleukopeniaPan: prefix meaning allLeuk/o: combining forms meaning deficiency-penia: suffix meaning deficiencyAll together the word means:Deficiency of all types of white blood cells

COMBINING FORMS?Pneumonoultramicroscopicsilicovolcanoconiosis

SUFFIXESAttached to the end of wordsModify meaning Types:

“Pertaining to”Surgical ProceduralDouble rConditional and Structural

ANALYZING MEDICAL TERMS1. Dissect

1.Divide the word into basic components2. Begin at the end

1.Suffix first, then prefix, then root 2.2 root words? Divide and read left -> right

3. Anatomical Order1.How does it occur in the body?

PRACTICE TOGETHER Ovariohysterectomy

Ovari/o/hyster/ectomy

SUFFIX: ectomy – removal PREFIX: Ovari/o – ovaryROOT: Hysteri/o – uterus

What’s it mean? Complete removal of ovaries and uterus

DISSECT THE VOCABULARYWorksheet 20 wordsDissect and define common medical terminology

OBJECTIVESID body planes, positional terms, directional terms, and body

cavitiesDefine terms related to body cavitiesID body systems by their components

ESSENTIAL QUESTIONWhy is positional terminology critical in veterinary medicine?

LEARN-OLOGY-ology

“the study of”Anatomy: student of body structurePhysiology: study of body functionsPathology: study of the cause, nature and development of

abnormal conditionsPathophysiology: study of changes in function caused by

diseaseEtiology: study of disease

POSITIONAL TERMSImportant for accurately and concisely describing body

locations and relationships of structures

In/out, up/down, etcNot specific

ACTIVITY: DIRECTIONAL DE-CODER1 sheet of lined paperFold is in half (like a hotdog) Put the directional words on one half , definition on the other

half

Table 2-1 in your book

POSITIONAL PLANES ACTIVITY

VET DENTISTRY POSITIONAL TERMS Rising trend in vet careTeeth surfaces are identified by the area it is near

Lingual, Palatal, Buccal, Vestibular, Occlusal, Labial, Contact ( mesial and distal)

BODY CAVITIES Hole/hollow space that contains organs

Cranial, Spinal, Thoracic/chest, Abdominial/ peritoneal, Pelvic

Regional TermsAbdomen, Thorax, Groin/ inguinal

MEMBRANES: HOLD IT ALL TOGETHERThin layer of tissue

Cover a surface, line a cavity, divide space or organMembranes to remember

PeritoneumParietal, Visceral (Peritonitis= inflammation of

the…)Umbilicus/Navel

(belly button) umbilical chord enters the bodyMesentery

suspends the intestines in abdominal cavityholds blood supply

POSITIONS USED IN EXAMSRecumbent: lying down

Types:Dorsal: on the backVentral (sternal): on your belly Left Lateral: on left sideRight Lateral: on your right side

Prone: lying ventral or sternalSupine: lying on your back

MOVEMENTAdduction: movement toward midlineAbduction: movement away from the midline

JOINT MOVEMENT Flexion: close jointExtension: straightening of the joint

hyper: flex or extend too farSupination: rotate to palm upPronation: palm turn downRotation: circular movement around an axis

ACTIVITY: PRACTICE MOVEMENTS

CELLS AND ACTIVITY Cytology: study of cellsDraw and label your cell diagram as a review Use your book to describe what each organelle does

GLANDS: IMPORTANT CELL TYPESSpecialized cell that secrete material used else where in the

bodyTypes:

Endocrine: secrete directly into the blood streamExocrine: secrete into the duct system

TISSUE TYPES Epithelial: Covers in and external body structures

Types: Squamous, Cubodial, Columnar, StratifiedMesothelium: forms the lining of serious membranes

Connective TissueTypes

Loose, dense, cartilageMuscle: contains cell material that can relax and contract

TypesSkeletal, smooth, cardiac

Nervous: can react to stimuli and conduct electric impulses

ACTIVITY BREAKUse your book

On a separate sheet of paperRepresent the different types of tissue

Epithelial 4 typesConnective 4 typesMuscle 3 types

THINK ABOUT THE BIG PICTURE!Cells make up tissuesTissues make up structuresStructures make up organsOrgans perform functionsFunctions required for survival

REVIEWVocab you learned
