  • 1. The Pharmacy Technician 4E Chapter 4Medical Terminology
  • 2. Topic Outline Terminology  Nervous System Organ system  Skeletal System terminology  Female Reproductive Cardiovascular System System Endocrine System  Respiratory System Gastrointestinal System  Urinary System Integumentary System  Senses Lymph and Blood  Drug Classifications Systems  Medical Abbreviations Muscular System
  • 3. Basic Elements of a Medical WordMedical science terminology is made up of a smallnumber of ROOT words (mostly Greek and Latinwords). 1. Word Root 2. Combining Form Root 3. Suffix Prefix + 4. Prefix SuffixThese four parts of a word are known as C.V.ELEMENTS. E.g. Peri – o - dont – ic (Periodontic: around the teeth)
  • 4. Word Root Main part or foundation of a word. Identify what part of the body a term is related to. All words have at least one word root. A word root may be used alone or be combined with other elements to form a complete word.  E.g. Gastr (word root) + itis (suffix) = GASTRITIS (complete word).
  • 5. Terminology Most root words originate from either Greek or Latin words. Words developed from the Greek language are often used to refer to diagnosis and surgery. Words from the Latin language generally refer to the anatomy of the body.
  • 6. Root - Part of Body Card - heart  Pneum - lung Cyst - bladder  Ocul - eye Gastr - stomach  Derma - skin Hemat - blood  Ven - vein Hepat - liver  Mast - breast My - muscle  Oste - bone Pector – chest  Nephr - kidney Neur - nerve  Ot - ear
  • 7. Combining Forms Correct pronunciation of medical words is very important. In order to make the pronunciation of root words easier, sometimes it is necessary to insert a vowel after the root. The combination of a root word and a vowel is known as a COMBINING FORM. “O” is the most common combining vowels IE: gastr / o = pronounced as GASTRO Word root Combining vowel
  • 8. Combining Words When a word has more than one root, a combining vowel is used to link the root to each other. Slashes separate elementsE.g. osteoarthritis oste/ o / arthr/ itis Word root Word root suffix Combining vowel
  • 9. Suffixes A suffix is added to the END of a word root or combining form to modify its meaning. Adding a suffix to the end of a word root, creates a noun or adjective with a different meaning.
  • 10. Meanings of certain suffixes-al = pertaining to = dent/al (pertaining to teeth)-er = one who = speak/er (one who speaks)-able = capable of being = playable (capable of being played)
  • 11. Prefixes A syllable or syllables placed BEFORE a word or word root to alter its meaning or create a new word.Some prefixes: Hyper- (excessive) Pre- (before) Post- (after) Homo- (same) Hypo- (under)
  • 12. HypoinsulinemiaHypo / insulin / emia Notice that there is no combining vowel in this word because the prefix ends with a vowel and the suffix Prefix suffix Word root begins with aLOW INSULIN BLOOD vowel.
  • 13. Cardiovascular System The Cardiovascular System distributes blood throughout the body using blood vessels called arteries, capillaries, and veins.  Blood transports nutrients to the body’s cells and carries waste products away from them. Blood is made up of red blood cells, white blood cells, platelets, and plasma.  Erythrocytes (red blood cells) transport oxygen from the lungs to the body and carbon dioxide from the cells to the lungs.  Leukocytes (white blood cells) fight bacterial infections by producing antibodies.
  • 14. Cardiovascular System Cont. The heart pumps blood through the cardiovascular system.  Blood pressures are reported as systole/diastole, i.e., 120/80.  A sphygmomanometer is used to measure blood pressure.  Blood pressure is reported (in mm Hg) and includes two number sequence.  Systolic phase is the increased pressure when blood is forced out of the heart.  The diastolic phase, or relaxation phase, is the second number reported in blood pressure monitoring.
  • 15. Cardiovascular System angi = vessel  phleb = vein aort = aorta  stenosis = narrowing card = heart  thromb = clot oxy = oxygen  vas(cu) = blood vessel pector = chest  ven = vein
  • 16. Cardiovascular System Cardiomyopathy = disease of the heart muscle Myocardial = concerning heart muscle Tachycardia = abnormal rapid heart action Phlebitis = inflammation of a vein Thrombosis = blood clot Hypertension = high blood pressure
  • 17. The Endocrine System Consists of the glands that secrete hormones, chemicals that assist in regulating body functions. Includes the pituitary gland, the adrenal glands, the thyroid gland, and the gonads (ovaries and testes). Pituitary gland = produces multiple hormones and is located at the base of the brain. It controls the body’s growth and the activity of the other glands. Thyroid gland = located just below the larynx and releases hormones important for regulating body metabolism.
  • 18. The Endocrine System Cont. Parathyroid glands = located on the thyroid gland. Thymus gland = located beneath the sternum. Pancreas = known for its production of insulin and glucagon. Adrenal glands = located on top of the kidneys and produce such hormones as aldosterone, cortisol (hydrocortisone), androgens, and estrogens. Medulla region = adrenal glands produce the catecholamines adrenaline (epinephrine) and noradrenaline (norepinephrine).

  • 21. The Gastrointestinal (GI) Tract Located in the abdomen and contains the organs that are involved in the digestion of foods and the absorption of nutrients. Organs include the stomach, small and large intestine, gallbladder, liver, and pancreas. Alimentary tract refers to the system that goes from the mouth to the anus. It contains organs such as lips, tongue, teeth, salivary glands, pharynx, esophagus, rectum, and anus, in addition to the GI tract. Several organs contribute to the digestion of foods by secreting enzymes into the small intestine when food is present. Ducts carry bile from the liver (hepatic duct) and the gallbladder (cystic duct) to the duodenum.
  • 22. Gastrointestinal TractConsists of organs that are involved in digestion of foods and the absorption of nutrients Gastritis = inflammation of the stomach. Gastroenteritis = inflammation of the stomach and Hepatitis = inflammation of the liver. Appendicitis = inflammation of the appendix Colitis = inflamed or irritable the intestinal tract colon Hematemesis = vomiting of blood Diarrhea = liquid bowel movement

  • 24. The Integument System Refers to the covering of the body and is the body’s first line of defense, acting as a barrier against disease and physical hazards. Helps control body temperature by releasing heat through sweat or by constricting blood vessels to act as insulation. It includes the skin, hair, and nails. Hair is made of keratinized cells. Finger nails and toenails are also composed of keratin. The mammary glands, or breasts, are also considered part of the integumentary system. The skin is composed of the epidermis and dermis. The epidermis has no blood or nerves and is constantly discarding dead cells. The dermis, which is made of living cells, contains capillaries, nerves, and lymphatics. The dermis also contains the sebaceous glands, sweat glands, and hair. The subcutaneous layer of tissue is beneath the dermis but is closely interconnected to it. It separates the skin from the other organs (for example, the muscular system, as in the illustration).

  • 32. The Muscular System Fibromyalgia = chronic pain in the muscles Myoplasty = plastic surgery of muscle tissue Tendonitis = inflammation of a tendon
  • 33. The Nervous System The Nervous System is the most complex of the body organ systems because there are over 100 billion neurons in the brain alone. The neuron (nerve cell), the basic functional unit in this system, transmits information from the brain to the entire body. The primary parts of this system are the brain and the spinal cord, called the central nervous system (CNS). There are subdivisions of the peripheral nervous system called the autonomic nervous system and the somatic nervous system. The autonomic nervous system controls the automatic functions of the body, e.g., breathing, digestion, etc. The somatic nervous system controls the voluntary actions of the body, e.g., muscle movements.
  • 34. The Nervous System Cereb = cerebrum Encephal = brain Mening = menignes Myel = spinal cord Neur = nerve
  • 35. The Nervous System Encephalitis = inflammation of the brain Neuralgia = severe pain in a nerve Neuroma = tumor or nerve cells

  • 42. The Female Reproductive System Gynecology = the study of the female reproductive organs Amenorrhea = absence of menstruation Dysmenorrhea = menstrual pain Endometriosis = abnormal growth of uteral tissue Viginities = inflammation of the vagina
  • 43. The Male Reproductive System The Male Reproductive System produces sperm and secretes the hormone testosterone. The testes (also called testicles) are the primary male sex organs.  They are oval-shaped organs enclosed in the scrotum. The seminal glands, located at the base of the bladder, produce part of the seminal fluid. The Vas Deferens are ducts that allow the passage of the sperm from the testes. The prostate gland is located at the upper end of the urethra. The penis (glans penis) is the external organ for urination and sexual intercourse. The urethra, by which urine and semen leave the body, is inside the penis.
  • 44. The Male Reproductive System Andr = male test = testicle Prostat = prostate gland Sperm = sperm vas = duct, vessel Vasicul =seminal vesicles
  • 45. The Male Reproductive System Prostatitis = inflammation of prostate Aspermia = inability to produce semen
  • 46. The Respiratory System The Respiratory System brings oxygen into the body through inhalation and expels carbon dioxide gas through exhalation. It produces sound for speaking and helps cool the body. Respiratory muscles (especially the diaphragm) expand the lungs automatically, causing air to be inhaled into the upper respiratory tract. The pleural cavity surrounds the lungs and provides lubrication for respiration. The pharynx directs food into the esophagus and air into the trachea. The larynx contains the vocal cords. The trachea, or windpipe, connects to the two bronchi (bronchial tubes) that enter the lungs.  As air enters through the nose, it is warmed, moistened, and filtered. Inside the lungs, the bronchial tubes branch out and lead to the alveolar sacs that are the site of gas exchange within the lungs. Alveoli are specialized tissues that are responsible for the exchange of gases between the blood and inhaled air.
  • 47. The Respiratory System aer, aero = air, gas pneum, pulmon = lung pector = chest Bronch = bronchus ox = oxygen capnia = carbon dioxide
  • 48. The Respiratory System Apnea = temporary failure to breath Bronchitis = inflammation of the bronchial membrane Cynosis = blue discoloration of the skin Hypercapnia = excessive carbon dioxide in the blood Hypoxia = low blood oxygen level Pneumonia = inflammation of the lungs Sinusitits = inflammation of the sinuses
  • 49. The Urinary Tract The Urinary Tract is responsible for removing wastes from the blood and includes the kidneys, ureters, urinary bladder, and urethras. The Kidney is the primary organ of the urinary tract. The Nephron is the functional unit of the kidney. There are several million nephrons in the kidneys. Urine is produced as plasma water and is filtered through the glomerulus, the filtrate is then collected in the tubule.  Waste materials from the blood may also be filtered into the tubule or may be secreted into the tubule at sites other than the glomerulus. Urine is the filtrate that moves along the tubule. Urine leaves the kidney through the ureters and collects in the bladder. It is excreted from the bladder through the urethra.
  • 50. The Urinary Tract cyst = bladder vesic = bladder ren = kidney nephr = kidney uria = urine
  • 51. The Urinary Tract Anuria = inability to produce urine Cystitis = inflammation of the bladder Nephritis = inflammation of the kidney Polyuria = excessive urination Uremia = toxic blood condition caused by kidney failure
  • 52. The Ears The Ears perform hearing, as well as the maintenance of body equilibrium. The External ear functions to capture sound waves and channels them inside the ear. The tympanic membrane (eardrum) is a funnel-shaped structure with an opening to outside. It contains glands that make earwax (cerumen) that protects the external ear. Malleus, incus, and stapes are three bony structures that transmit sound from a vibrating tympanic membrane to the cochlea and located in the middle ear. The eustachian tube connects the middle ear to the nose and throat, serving to equalize the air pressure on both sides of the tympanic membrane. The labyrinth is the principal structure in the inner ear is which consists of the vestibule, the cochlea, and the semicircular canals. The cochlea contains the organ of hearing. When sound waves are transmitted to the cochlea, it converts them into nerve impulses that are sent to the brain for interpretation. The semicircular canals and the vestibule are primarily responsible for body equilibrium.
  • 53. Senses: HearingBelphar = eyelidcor = pupillacrim = tearcorne = cornearein = retinabi = twoopia = vision
  • 54. The Eyes The Eyes are the organs that provide sight. The eyelids protect the eye and assist in its lubrication. The conjunctiva is the blood-rich membrane between the eye and the eyelid. There are several glands that secrete fluids to protect and lubricate the eye; the lacrimal glands above each eye secrete tears and the meibomian glands produce sebum. Canalicula (tear ducts) drains excess fluid into the eye. The eye has three layers. The outer layer is composed of the sclera and the cornea. The sclera is the white part of the eye. The cornea is transparent so the iris (the color of the eye) and the pupil (the opening of the eye) are visible. The middle layer is called the choroid and contains blood vessels that nourish the entire eye. In the third layer, the lens focuses light rays on the retina. The vitreous humor (one of two fluids in the eye) fills the space between the retina and the lens. Rods and cones within the retina they are responsible for visual reception. The optic nerve within the retina transmits the nerve impulses to the brain for interpretation.
  • 55. Senses: Sight Blepharitis = inflammation of the eyelid Conjunctivitis = inflammation of the conjunctiva Retinitis = inflammation of the retina
