hey everyone welcome back to another medical terminology lesson this lesson is on an introduction to the dermatologic system so more specifically we're going to look at different prefixes and suffixes to help describe certain skin lesions and certain skin conditions but this is only a brief broad overview if you want more information on specific terms used for certain skin conditions and skin lesions please check out my lesson on introduction to dermatology so before we get into the dermatologic system let's just talk about the word dermatologic so if we break down that word burmat or dermato means skin all lodge that part of the word comes from ology meaning study of and the suffix ich means pertaining to so when we actually put this all together dermatologic means pertaining to the study of skin and before we move into the different prefixes and suffixes i want to talk about the word integumentary so you might have heard of the integumentary system and it's actually a bodily system involving skin and related appendages so we're going to get into the different prefixes and suffixes describing different parts of the skin so the first prefix we're going to talk about is the prefix cutane which means referring to the skin and then i didn't mention this before but the prefix impegument or integumento refers to skin as well so that's where that part of the integumentary system comes from integument means skin so those both refer to the skin so we're going to look at different medical terms that describe the different layers of skin from most superficial down into deeper areas of the skin so the first one is the prefix epiderm which refers to epidermis so the epidermis is the first top layer of the skin and you can think of words like epidermal like an epidermal cyst the second is derm or dermato we looked at this word before it refers to the skin but it also refers to the dermis and the dermis it be the second layer of the skin broadly speaking so it's the layer deeper to the dermis and then there's also a related suffix derma which refers to the dermis as well but it usually refers to a condition of the dermis so different types of conditions like pioderma those types of words and then we can also see hypoderm so hypoderm refers to the hypodermis so below the dermis so if we actually broke down this prefix even more hypo means below or less than and derm refers to the dermis or the skin so hypodermis refers to the area below the dermis other parts of the dermatologic system include the nail so the suffix nikia refers to the area surrounding the nail but we can also see the prefix onico or onikio referring to the nail as well so you can think of words like onychomycosis a fungal infection of the nail and other words that describe the skin include the prefix carrot which refers to keratin so skin is made of keratin but it can also refer to hard or thickening so carrot the word you can think of a word like hyperkeratosis so hyperkeratosis is a thickening of the skin usually due to friction another prefix that is often used with regards to the skin is adino so you've probably seen this if you've looked at my other lessons adino means gland so you can think of words like adenitis so an inflammation of the gland other words that can also be used in the dermatologic system include adipo or adipo so this refers to fat you can think of words like adipocyte a fat cell and we can also think of words like lipo so lipo also refers to fat and you can think of words like liposuction other terms to describe the skin include fibro and the prefix fibro literally means fibrous so fibrous tissue another one would be call or calla referring to collagen and the prefix piyo refers to pus so we talked about pioderma as a possible word so pus in the skin we can also see prefixes like sibo which means or refers to sebum another prefix that can be used to describe a skin lesion more specifically is the prefix bowl which refers to bula ebola are fluid-filled raised skin lesions and you can think of a medical condition known as bolus penfagoid so bolus penfangoid is a skin condition that has ola so again fluid-filled raised lesions and then another prefix you might see is vesicule which refers to vesicles so you can think of things like herpes as a possible associated medical condition with this term and some other medical terms that can refer to conditions include edema or edem which refers to fluid filled or swelling so we can think of edematous so a part of the body or part of the skin that is swelling fluid filled another prefix is cellular and cellular really means cell but it really refers to a skin condition and you can think of medical conditions like cellulitis so itis meaning inflammation so inflammation of really cells but really its a skin condition and then another word you might see with regards to other dermatologic conditions includes tinea and tinea really refers to a fungal infection so i just wanted to add that here for completeness and it's also important for describing skin lesions in other skin conditions we need to use colors so you've probably seen these in other lessons but i just want to quickly go over them erythro or eryth means red milano means black so you can think of melanocyte xanth means yellow so xanthoma a yellow the positive cholesterol usually around the eyes jaund means yellow and you can think of words like jaundice and the prefix cyano means blue so you can think of words like cyanotic or cyanosis so when the skin appears blue so i just want to quickly go over those as well if you want more information on different colors please check out my lessons on those topics so again we learned about some of the prefixes and suffixes we can use to describe certain skin conditions so we talked about words like piyo referring to pus we talked about bowl referring to bula and we talked about vesicle referring to vesicles and we can also see here edem or edema referring to fluid filled or swelling cellular referring to cell but more specifically the condition cellulitis and tinia refers to fungal infections and then some of these colors can be used to describe certain types of cells but also certain types of conditions so now that we've learned those dermatologic terms let's put them to practice so the first word we're going to look at is perinekia so if we break down the word prefix pera means nearby so this would have been learned in a basics lesson and the suffix nikia we learned in this lesson refers to an area surrounding the nail so perinekia means nearby the area surrounding the nail that's what perinekia means so when you actually look at a finger in the perinekei is actually the area on the sides of the nail the next word we're going to look at is subcutaneous so again we break down the word the prefix sub sub means below and the suffix cutane or cutaneous means referring to the skin so when we put this together subcutaneous means referring to below the skin so the subcutaneous layer is often below the dermis or hypodermis and the next word we're going to look at is erythroderma so we break down the word erythroderma so erythro refers to the color red and the suffix derma refers to the skin so erythroderma means a red skin so it's actually a condition where we can see a reddened skin erythroderma so again perinekia we're breaking it down para meaning nearby nikkia area surrounding the nail so it's nearby the area surrounding the nail it's literally what that means subcutaneous sub meaning below cutaneous meaning referring to the skin so subcutaneous is referring to below the skin and then erythroderma erythro meaning red so you can think of words like erythrocyte so red blood cell and the suffix derma meaning skin so erythroderma means reddened skin so that was a quick lesson on medical terminology with regards to the dermatologic system if you
