This subject enhances and reinforces an understanding of the different terms used in the clinical and classroom setting. Additionally, it includes an introduction to the basic nomenclature and general organization of the human body as detailed study of the different systems, its components structures, and functions. Course Outcomes: At the end of the course, the students should be able to: 1.Know the basic terminologies essential in understanding human structure and function. 2.Know the different levels of structural organization of the human body from cell to the different organ systems, their characteristics, components, and their relationship from each other. 3.Enhance student’s skills in identifying the different terms of the human body as well as their functions and relate it to the various pathologic conditions.  5 Chapter 1 Introduction to medical terminology This chapter comprises of the basic concepts and terms that will be widely used in the succeeding chapters and lessons. It will enable the learners to better understand the subject matter. Intended Learning Outcomes: 1.Explain the purpose of medical terminology 2.Name the languages from which most medical word parts are derived 3.Explain what combining forms are, why they are used 4.Determination of medical terms using roots, prefixes, and suffixes. 5.Medical terms and word part dissection Key Terms: Roots Suffixes Prefixes Elements Compound Words Let’s Begin! Medical terminologies Professional language of those who are directly or indirectly engaged in the art of healing Difficulties gradually disappear as students assimilate a working knowledge of the elements of medical terms, which in turn, enables them to analyze words etymologically and according to their meaning. Memorization – steppingstone to better understanding Primary Goal: to help develop the ability to read and understand the language of medicine Promoting knowledge on elements of medical terms, understanding standard abbreviations, being able to spell medical terms and appreciating the logical method found in analyzing medical terms A. Basic concepts Majority of medical terms came from Greek and Latin ancestry; some from modern language like German and French Study of medical terminology can enrich one’s understanding of history, language, and medicine Pronunciation of medical terms have no rigid rules flexibility different languages used  6 Many medical terminologies are combinations of components from these ancient languages As vocabulary grows notice patterns increased knowledge recall and recognize easily and quickly Word building misleading: take the word apart/break the word to better understand the word Not learned overnight Every industry has its fair share of jargon. While most of us don’t need to understand discipline-specific terminology outside of our own profession, medical vocabulary is a notable exception. Understanding and knowing the medical terminologies is one of the basic foundations of any health care profession. At the same time medical terminology helps us understand what is going on with our health. B. Key Concepts 1.root or base word Refers to the main body of the word May be accompanied by a prefix or suffix Example: adenoma Aden- (base/root) = gland -Oma (suffix) = tumor Adenoma = gland tumor 2. Prefix One or two syllables or word parts placed before a word to modify or alter its meaning Example: hemigastrectomy Hemi (prefix) = half Gastr (base/root) = stomach -ectomy = removal or excision Hemigastrectomy = removal of the half of the stomach 3. Suffix One or two syllables or word parts attached at the end of a word to modify or alter its meaning Example: hysterectomy Hyster-(base/root) = uterus -ectomy = removal or excision Hysterectomy = removal of uterus Suffix meaning one who – selected suffixes meaning one who include –er and –ist Example: Pathologist Path (root/base) – disease or morbid condition O (combining-form element, vowel) -logy (suffix) = science or study of  7 -ist (suffix) = one who Pathologist = one who studies disease or morbid conditions Suffix meaning pertaining to – selected suffixes include -ac, -ic, -al, -eal, -ary, and –ous Example: hemic Hem- (base/root) = blood -ic (suffix) = pertaining to Hemic = pertaining to blood 4. Combining-form element Results when a vowel, usually a, e, i, o, is added to a word root or base. The vowels used most commonly as combining-form elements are a, i, or o. The vowel is usually deleted from a combining-form when the next letter that follows is also a vowel Example: proctitis Procto- (combining form) = denoting relationship to the rectum -itis (suffix) = inflammation of Proctitis = correct combination Proctoitis = incorrect combination (o should be dropped) Proctitis = inflammation of the rectum 5. Compound words Result when two or more root or base-word elements are used to form a word Usually, adjectives or nouns are added to a root word to form compound words Compound words may include a combining form, a root or base word element, and a suffix or word ending Example: myocardiopathy Myo- (combining form element) = relationship to muscle Cardio- (combining-form element) = relationship to heart -pathy (suffix) = disease or morbid condition Myocardiopathy = disease of the heart muscle *Caution and flexibility are required in breaking down terms Example: anemia -emia (suffix) = blood An- (prefix) = without, not Anemia = without blood *In the strict sense, the term “anemia” may seem to mean no blood (absence or total lack of blood) rather than the attenuated quality of blood.  8 When breaking down terms, it is more helpful to start the process by: Beginning with the suffix Proceed to the root or root and prefix Root words Component Meaning Example Meaning Blast Germ/ immature cell Blastoma Cancer made of immature cell Carcin Cancer Carcinogenic Cancer causing Cardio Heart Cardiotoxicity Toxicity to the heart Cyto Cell Cytotoxic Toxic to the cell Derma Skin Dermatitis Inflammation of the skin Histio Tissue Histology Study of tissue Hepati Liver Hepatoblastoma Liver cancer Malign Bad/harmful Malignant Growing or spreading Nephron Kidney Nephrotoxic Harmful to the kidney Toxo Poison Toxicology Study of poison Suffixes Component Meaning Example Meaning aemia Condition of blood Leukaemia Cancer of the blood cell ectomy Excision or Nephrectomy Excision of the kidney removal itis Inflammation Hepatitis Inflammation of the liver logy Study/science of Cytology Study of cell oma Tumor Retinoblastoma Tumor of the eye pathy Disease Nephropathy Diseases of the kidney osis Disease condition Necrosis Dying cells Prefix Meaning Example Meaning An/A Without/absence or lack of anuria lack of urine output AB Away from abnormal a structure or process that is not normal AD Near/toward glands situated one upon the upper end of each kidney Bi Two or both ambidextrous using both hands Dys Difficulty/painful Dyspnoea difficulty in breathing  9 Ecto Outside Ectopic Pregnancy outside the uterine cavity Endo Inside Endoscope Instrument use to look inside the body cavities Epi Upon Epidermis Outer layer of the skin Hyper Excessive or above Hyperglycemia Increase blood sugar Hypo Beneath or below Hypodermis Below the skin Inter Between Intercostal Between the ribs Intra Within/ inside Intravenous Into the vein Para Beside/about/near Parathyroid Beside thyroid gland Peri Around Pericardium Membrane around the heart Pre Before Prenatal Before birth Post After Post-surgical Stage after surgery state Sub Below/under Submucosa Tissue below mucosa membrane Syn Together Syndrome Group of symptoms occurring together  10 CHAPTER 2 Body structures This chapter comprises of the basic concepts of structural organization of the body which includes anatomical positions, body planes and positions, body cavities and abdominal regions. Intended Learning Outcomes: 1. Explain the purpose of medical terminology 2. Name the languages from which most medical word parts are derived 3. Explain what combining forms are, why they are used 4. Determination of medical terms using roots, prefixes, and suffixes. 5. Medical terms and word part dissection Key Terms: Anatomical position Body planes Body positions Body cavities  11 Let’s Begin! Anatomical position of the body Body is erect Eyes look straight to the front Upper limbs hang at the sides with palms facing forward Lower limbs are parallel with the toes pointing forward Whether the body lies face upward or downward, or in any other positions, the relationships of structure are always described as if the body were in the anatomic position Figure 1 Anatomical Position of the body __________________________________________________________________________________  12 Planes of the body 1.Frontal or coronal – vertical plane parallel to coronal suture of the skull; divides body or structure into anterior and posterior portions 2.Horizontal – plane parallel to the horizon 3.Longitudinal – plane parallel to the long axis of the structure 4.Median – lengthwise plane that divides the body or structure into right and left halves 5.Sagittal – any vertical plane parallel to the sagittal suture of the skull and the median plane Figure 2 Planes of the body _______________________________________________________________________________________ Positions and direction terms Afferent – conducting toward a structure  13 Efferent – conducting away from a structure Anterior or ventral – toward the belly Posterior or dorsal – toward the back Caudal – Toward the back, toward the tail Lateral – toward the side Intermediate – between medial and lateral Medial – toward the median plane/ middle/midline Superficial – near the surface Deep – away from the surface Distal or peripheral – away from the beginning of a structure; away from the center Proximal – toward the beginning of a structure Inferior or caudal – away from the head; situated below another structure Superior or cephalic – toward the head; situated above the another structure Median – in the middle of the structure Central – toward the center Supine: When lying face downward Prone: When lying face downward Bilateral: Involving both sides of the body Unilateral: Involving one side of the body Ipsilateral: On the same side of the body Contralateral: On opposite sides of the body Parietal: Relating to a body cavity wall Visceral: Relating to organs within body cavities _________________________________________________________________________________ Position and directional terms of the body can affect the description of the body parts relative to each other. Thus, it is very vital that terms are defined and understood properly to better correlate it to different body parts. For an instance, in anatomical position, the elbow is above the hand, but in supine or prone position the elbow and hand are at the same level.  14 Body Cavities Human’s internal organs are called visceral organs; located within specific cavities Two main cavities 1. Dorsal Cavity Cranial cavity –holds the brain Spinal cavity – spinal cord and is protected by secretions of the vertebrae 2. Ventral Cavity Thoracic cavity – lungs, heart, esophagus, trachea, and thymus gland Abdominopelvic cavity –Abdominal cavity –stomach, liver, spleen, gallbladder, most of the large and small intestines – Pelvic cavity – remaining portions of the large and small intestines, rectum, urinary bladder, internal reproductive organs Oral cavity – teeth and tongue Nasal cavity – divided into left and right by the nasal septum Orbital cavity – contain the eyes and related muscles and nerves Middle ear cavities – middle ear bones Abdomen Figure 3 - Regions and Quadrants of the Abdomen  15 Anatomic divisions of the abdomen Hypochondriac region (upper lateral regions beneath the ribs) Epigastric region (region of the pit of the stomach) Lumbar region (middle lateral regions) Umbilical region (region of the navel) Inguinal region (lower lateral regions) Hypogastric region (region below the umbilicus) Clinical division of the abdomen Upper right quadrant – URQ Upper left quadrant – ULQ Lower right quadrant – LRQ Lower left quadrant – LLQ BACK Figure 4  16 Chapter 3 Integumentary system The integumentary system consists of the skin and accessory structures such as hair, nails, and glands. This chapter will also include general functions and different terminologies related to the integumentary system Intended Learning Outcomes: 1.Identify the general functions of integumentary system 2.Identify the different terminologies related to the anatomy of integumentary system 3.Give the terminologies needed for physical examination of the integumentary system 4.Recognize tests that help diagnose integumentary system disorder 5.Identify and define clinical symptoms and disorders of the Integumentary system and their treatments.  17 Key Terms: Integumentary System Skin Hair Nails Glands Let’s Begin!
