Medical Terminology and Anatomy Review

Intro: ● A thorough knowledge of human anatomy is essential to successful coding, as is the ability to understand medical terminology used to describe and document medical procedures and services ● This chapter introduces the basic elements of human anatomy and reviews medical vocabulary and terminology ● Objectives: ○ Understand the language of medicine ○ Review word elements such as combining forms, prefixes, and suffixes ○ Acquire an understanding of procedural and diagnostic terms ○ Understand anatomy as it relates to coding Medical Terminology ● To code medical procedures and diagnoses accurately, you first must learn the language of medicine ○ Many medical terms used today derive from the ancient Greeks and Romans ■ EX: latin phrase - pro re nata, which means when necessary- is the origin of the medical abbreviation PRN ● The best way to learn medical terminology is by understanding word parts and elements of medical language - root words, prefixes, and suffixes - which serve as the foundation of out medical vocabulary ○ When you understand the meanings of each word part, interpretation of tens of thousands of complex medical terms becomes easier Root ● The base of the word is the root ○ Root words are terms standing alone as the main portion of a medical term ○ A prefix, suffix, and combining vowel may accompany it ○ The root word is the word part holding the fundamental meaning of the medical term, and each medical term contains at least on root or base word ○ A word can have more than one root and a root may be used for different

meanings based on the body system referred to ● Combining vowels are attached to root words to link the root word with the suffix, or one root word to another root word ○ Combining vowels also make medical terms easier to pronounce ○ The most common vowels are O and I ○ Occasionally, these vowels are dropped altogether, such as when the suffix being with a vowel ■ However the combining vowel is always placed between two root words, even when the second root word begins with a vowel ● Combining forms are root words with a combining vowel ● Common root words and their combining forms associated with the body systems include: ○ Integumentary System Term Definition Derm/o Skin Dermat/o Skin Hidr/o Sweat, perspiration Kerat/o Keratin, horny layer of skin Melan/o Dark, black, melanin Onych/o Nail Seb/o Sebum, sebaceous gland Trich/o Hair ○ Musculoskeletal System Term Definition Arthr/o Joint Burs/o Bursa, sac of fluid near joint Chondr/o Cartilage Erg/o Work Fasci/o Fascia Kin/o, kinesi/o Movement

and divides the body into front (anterior) and back (posterior) sections ■ Transverse (horizontal) (axial) - cuts horizontally through the body and separates the body into upper (superior) and lower (inferior) sections Structure of the Human Body ● The structure of the human body is divided into four categories: ○ Cells ○ Tissues ○ Organs ○ Systems ● Each structure is a highly organized unit of smaller structures ● Cells: ○ The cell is the basic unit of all living things ■ Human anatomy is composed of cells varying in size and shape according to function: ● Cell membrane forms the boundary of the cell ● Cytoplasm makes up the body of the cell ● Nucleus is the small, round structure in the center of the cell ● Chromosomes are in the nucleus of the cell; they contain genes that determine hereditary characteristics ● Tissues ○ Tissue is a group of similar cells performing a specific task: ■ Muscle tissue produces movement ■ Nerve tissue conducts impulses to and from the brain ■ Connective tissue connects and supports various body structures: adipose (fat) and osseous (bone) ■ Epithelial tissue is found in the skin and lining of the blood vessels, respiratory, intestinal, urinary tracts, and other body systems ● Organs ○ Organs are two or more kinds of tissue, together performing special body functions ■ EX: skin is an organ composed of epithelial, connective, and nerve tissue ● Systems ○ Systems are groups of organs working together to perform complex body functions

■ EX: the nervous system is made up of the brain, spinal cord, and nerves ● Its function is to coordinate and control other body parts ● Medical Terms Related to Cells and Tissues ○ Cell membrane - surrounds and protects the individual cell ○ Nucleus - small, round structure within the cell containing chromosomes and nucleoplasm (DNA and RNA) ○ Chromosome - linear strand made of DNA carrying genetic information ○ Cytology - study of cells including the formation, structure, and function of cells ○ RNA - Contained within the nucleus, is transcribed from DNA by enzymes and plays a crucial role in protein synthesis ○ Gene - specific segment of base pairs in chromosomes; functional unit of heredity ○ Mitosis - cells divide and multiply to form two cells Body Cavities ● The body is not a solid structure ○ It has 5 cavities, each of which contains an orderly arrangement of internal organs ● Dorsal cavity includes: ○ Cranial Cavity: the space inside the skull, or cranium, containing the brain ○ Spinal (Vertebral Canal) Cavity: the space inside the spinal column containing the spinal cord ● Ventral Cavity includes ○ Thoracic, or Chest cavity: the space containing the heart, lungs, esophagus, trachea, bronchi, and thymus ○ Abdominal Cavity: the space containing the lower portion of the esophagus, the stomach, intestines (excluding the sigmoid colon and rectum), kidneys, liver, gallbladder, pancreas, spleen, and ureters ■ The abdomen can be divided into four sections: right upper quadrant (RUQ), left upper quadrant (LUQ), right lower quadrant (RLQ), and left lower quadrant (LLQ) ● EX: the spleen is located in the left upper quadrant of the abdomen ○ Pelvic Cavity: the space containing the urinary bladder, certain reproductive organs, part of the large interesting, and the rectum

body and consists of a thin layer of stratified squamous epithelium attached to a thicker underlying layer of connective tissue ● The cutaneous membrane is skin ● Connective Tissues support and connect tissues of the body ○ Connective tissue is divided into four general groups: connective tissue proper, cartilage, bone, and blood Integumentary System ● The largest organ system in the body is comprised of three structures: ○ Skin ○ Hair ○ Nails ● These structures work together to provide the following within the body: ○ Protection from injury, fluid loss, and microorganisms (bacteria, virus, fungus, yeast) ○ Temperature regulation ○ Fluid balance (excretion) ○ Sensation Skin ● Two layers make up human skin: dermis and epidermis ○ Each layer and its components are listed below ○ Be familiar with the various layers and be able to apply this knowledge when choosing the appropriate CPT code ● Epidermis ○ The epidermis is composed of four to five layers (depending on location) called stratum ■ The stratum lucidum layer is normally found only on the palms of the hands and the soles of the feet ○ The various strata are: ■ Stratum Corneum - also called the horny layer; outermost layer ■ Stratum Lucidum (Palms and soles) - clear layer ■ Stratum Granulosum -granular layer of cells ● It contains two types of granules: keratohyalin granules, and lamellated granules ■ Stratum Spinosum - composed of prickles cells that are interwoven for

protection ■ Stratum Basale (Stratum Germinativum) - deepest of the five layers and made of basal cells ● Dermis ○ The dermis is located deeper, just under the epidermis ■ It has two strata ● Stratum Papillare - thin superficial layer interlocked with the epidermis ● Stratum Reticulare - thick layer of dense, irregular connective tissue ○ The dermis contains many important structures nourishing and innervating the skin: ■ Vessels carrying blood and lymph ■ Nerves and nerve endings ■ Glands ■ Hair follicles ○ The dermis lies on the subcutaneous (beneath the skin) tissue ■ The subcutaneous tissue is known as the hypodermis and is not considered to be a layer of the skin ■ The subcutaneous tissues are mostly composed of fatty or adipose tissue, plus some areolar tissue (loose connective tissue consisting of a meshwork of collagen, elastic tissue, and reticular fibers) ■ The hypodermis serves to protect the underlying structures, prevent loss of body heat, and anchor the skin to the underlying musculature ■ The fibrous connective tissue, referred to as superficial fascia, is included in this layer ○ Understand the stratification of the tissue layer and the structures lying within when coding for surgical procedures throughout the body and, most particularly, for those procedures performed on the integument ■ When applying CPT codes found in the 10000 section, you must know on which layer the provider worked ● Medical Terms Relating to Skin ○ Allograft -a graft transplanted from one person to another who is not genetically identical; also called an allogenic skin graft

○ Inner and outer sheaths protect and mold the growing hair shaft surrounding the follicle ○ The inner sheath ends at the opening of the sebaceous gland, which secretes sebum; it may pocket, causing benign lesions on the scalp (report removal of these benign cysts using CPT codes 11400- ○ Muscles called the arrector pili attach to the outer sheath and cause hair to stand up when the muscles contract ○ The shaft is composed of keratin in three layers: the medulla, cortex, and cuticle ○ Pigment cells in the cortex and medulla give hair its characteristic color Nails ● The fingernail is made of keratin acting as a protective plate and as a counterforce to the fingertip to increase sensory input of touch ○ Nails grow all the time, but growth slows with age and poor circulation ○ Fingernails grow approximately three millimeters per month; toenails grow more slowly, at approximately one millimeter per month ● The nail is divided into six parts: the root, nail bed, nail plate, eponychium (cuticle), perionychium, and hyponychium ○ The root, or the germinal matrix, lies beneath the skin behind the finger nail and extends several millimeters into the finger ○ The root produces most of the volume of the nail and the nail bed: its edge is the white, crescent-shaped structure called the lunula ○ The nail bed, called the sterile matrix, extends from the edge of the lunula to the hyponychium ○ The nail bed contains the blood vessels, nerves, and melanocytes (melanin- producing cells) ○ The nail plate is the actual fingernail, made of translucent keratin ○ Blood vessels underneath give the nail its pink appearance; the grooves along the inner length of the nail plate anchor the nail to the nail bed ○ The cuticle, also called the eponychium, lies between the skin of the finger and the nail plate fusing the skin of the finger to the nail plate ○ The perionychium, also known as the paronychial edge, is the skin overlying the plate on its sides and is the site hangnails, ingrown nails, and an infection of the skin called paronychia ○ The hyponychium is the junction between the free edge of the nail and the skin

● Medical Terms Related to Hair and Nails ○ Alopecia - loss of hair ○ Follicles - specialized structures required for hair growth ○ Hair follicles - sacs holding the root of hair fibers ○ Hair Papilla - knoblike indentation at bottom of hair follicle containing the blood supply to hair root ○ Lunula - little moon area of nail ○ Nail body - visible part of nail ○ Nail Bed - skin below the nail, epidermis, and dermis (sterile matrix) ○ Onychitis - inflammation of nail matrix ● CPT Codes in the 10000 range address procedures and services relative to the integumentary system Musculoskeletal System ● The musculoskeletal System is a system of muscles, joints, tendons, and ligaments providing movement, form, strength, and protection ○ Various muscle and bone types work together in this body system ● Bones ○ Bones are composed of rigid connective tissue and provide the following functions: ■ Form the skeleton ■ Provide the chief means of support for the body ■ Provide the mechanism for motion ■ Protect vital organs ■ Serve as a production factory for blood cells (EX: marrow) ■ Store calcium, phosphorus, and magnesium ○ Bones, classified according to shape are: ■ Long- bones longer than they are wide and found in the limbs (eg. femur, humerus) ● These bones are named for their elongated shape, not their size ■ Tubular - long bones ■ Short - roughly cube-shaped bones such as carpal bones of the wrist and tarsal bones of the ankle ■ Sesamoid - a short bone (shaped like a sesame seed) formed within tendons, cartilaginous in early life and osseous (bony) in the adult

Medical Terminology
● To code medical procedures and diagnoses accurately, you first must learn the language
of medicine
○ Many medical terms used today derive from the ancient Greeks and Romans
■ EX: latin phrase - pro re nata, which means when necessary- is the origin
of the medical abbreviation PRN
● The best way to learn medical terminology is by understanding word parts and elements
of medical language - root words, prefixes, and suffixes - which serve as the foundation
of out medical vocabulary
○ When you understand the meanings of each word part, interpretation of tens of
thousands of complex medical terms becomes easier
Root
● The base of the word is the root
○ Root words are terms standing alone as the main portion of a medical term
○ A prefix, suffix, and combining vowel may accompany it
○ The root word is the word part holding the fundamental meaning of the medical
term, and each medical term contains at least on root or base word
