Integumentary System Disorders


Integumentary System Structure and Function



Integumentary System


The skin and its accessory organs (hair, nails, and glands) are the integumentary system of the body. Integument means covering.

Skin contains two types of glands that produce important secretions. These glands under the skin are the sebaceous and the sweat glands.

Sebaceous glands produce sebum, an oily secretion, and sweat glands produce sweat, a watery secretion.

Layers of the skin

  1. Epidermis : a thin, cellular membrane layer (Outermost layer of the skin).
  2. Dermis (Corium) : Middle layer of the skin. Dense, fibrous, connective tissue layer. (Sebaceous glands are located in dermal layer. They secrete an oily substance called sebum)
  3. Subcutaneous tissue: thick, fat-containing tissue. (Lipocytes are predominant in the subcutaneous layer)
Integumentary System - Vocabulary

Squamous epithelial cells are flat and scale-like. In the outer layer of the skin, these cells are arranged in several layers (strata) and are therefore called stratified squamous epithelium.

apocrine sweat gland: One of large dermal exocrine glands located in the axilla and genital areas.

Basal layer: The deepest region of the epidermis; it gives rise to all the epidermal cells.

collagen: Structual protein found in the skin and connective tissue.

Stratum corneum: The outermost layer of the epidermis, which consists of flattened, keratinized (horny) cells.

keratin: Hair protein material found in the epidermis, hair, and nails. Keratin means horn and is commonly found in the horns of the animals. The basal layer of the epidermis contains special cells called melanocytes. Melanocytes form and contain a brown-black pigment called melanin.

albino: Person with skin deficient in pigment (melanin)

lunula: is a semilunar (half-moon), white region at the base of the nail plate.

paronychium: is the soft tissue surrounding the nail border.

cuticle: a narrow, band of epidermis (layer of keratin)

epithelium: Layer of skin cells forming the outer and inner surfaces of the body.

hair follicle: Sac within which each har grows.

lipocyte: A fat cell.

melanin: Major pigment that gives the skin color. It is formed by melanocytes in the epidermis.

pors: Tiny opening on the surface of the skin.

sebum: Oily substance secreted by sebaceous glands.

squamous epithelium: Flat, scale-like composing the epidermis.

statified: Arranged in layers.

stratum (plural: strata) : A layer (of cells).

stratum corneum: The outermost layer of the epidermis, which consists of flattened, keratinized (horny) cells.

epidermis: Outer most layer of the skin.

dermis: Middle layer of the skin; also called corium.

subcutaneous tissue: The innermost layer of the skin, containing fat tissue.

Referencing Refinements


Because medical terminology uses so many Greek and Latin terms, the spellings are not always what you would expect in English.

Sound everything out and look up the sounds you are hearing based on many different ways of spelling the sounds, as in "f" or "ph," and as in "k" or "ch."

Remember, too, to work your way through the vowels after the main sound: if "ch" is the main sound you would then look up words with a-e-i-o-u-and y following "ch."

Examples:

> You hear --"a-k"--as in acanthosis; check ac, acc, ach, ak, aq

> You hear--"ace"--as in acebutolol; check ace, aci, ase, asy

> You hear--"acu"--as in acute; check in acu, accu

> You hear--"ad-e"--as in adenovirus; check ade, adi, ady

> You hear--"aero"--as in aerobic; check aro, arro, ary, ero, ery

> You hear--"alla"--as in allachesthesia; check alla, alle, allo, ala, ale, ali, allyl, alo

> You hear--"ambi"--as in ambient; check ambi, ambly, ambe

> You hear--"am-e"--as in ametropia; check ame, ami, amy

> You hear--"ank"--as in ankyloglossia; check anch, ank

> You hear--"ante"--as in antegrade; check ante, anti

> You hear--"a-f"--as in aphasia; check aph, af

> You hear--"apo"--as in apoplexy; check api, apo, ape, appe, appi, appo, apy

> You hear--"antree"--as in antresia; check antre, antri

Word Research Techniques


Word Research Techniques

The ability to research medical terms that you are not familiar with is the paramount skill that will be called on each day you practice medical transcription.

There will constantly be new terms that need to be researched in reference books, along with a need to look up potential words when the word has been dictated in a manner that makes it unclear, i.e. the physician cuts off either the first part or last part of a word.

1. Always look under the noun first.

In the following examples, the word to look up is in bold.

postsphenoidal bone / Unna's boot / tardive dystonia

submantle layer / appendiceal mass / suppurative mastitis

olivary nucleus / Hodgkin's sarcoma / growth quotient

2. If the term to be researched is a syndrome, also check under these terms: sign / disease / symptom / process / phenomenon

3. Don't forget to look up anatomical terms under their Latin names. Many physicians will give the Latin names for muscles, veins, arteries, etc. See below for a listing of several Latin names and their English equivalents.

LATIN

ENGLISH

vena

vein

musculus

muscle

arteria

artery

ligamentum

ligament

nervus

nerve

4. If you can't find the term you need under the noun, then look under each word you hear. You will eventually run into the term you are looking for. In time, this will be accomplished faster and easier with the use of Google or Yahoo opposed to the use of books.

5. A trick I have always used in researching a word is to work my way through the vowels (a, e, i, o, u, and y) in order to eventually locate the correct spelling of the word I need. In medicine, there are many words that might sound like they begin with an "a," but that really begin with another vowel. Use this trick of working your way through the vowels to eventually find the correct spelling of the word you are researching.

6. Always sound out what you are hearing and research according to every phonetic way possible of spelling the word.

For example:

If you hear "fima"... don't forget that "phy" has the same sound, so the word is "phyma."

If you hear "condro"... don't forget that this could also be "chondro" or "kondro."

If you hear "terigoid"... don't forget that in medicine, there are several terms that have the "t" sound that start with "pt." The word is "pterygoid
