Integumentary System Integumentary System OverviewOverview
Composed of skin (integument), and its appendages (hair, nails, sweat glands and sebaceous glands)
Protects body for injury or intrusion of microorganisms
Helps regulate body temperature
Houses receptors for sense of touch

SkinSkin Largest organ in the body
Divided into an outer layer and an inner layer: epidermis — outer layer dermis (corium) — inner layer
![Page 10: Integumentary System Chapter 5. Combining Forms for the Integumentary System adip/oadiposis lip/olipoma steat/osteatoma dermo/ohypodermic dermat/odermatology](https://reader036.vdocuments.site/reader036/viewer/2022062717/56649e2f5503460f94b1fe94/html5/thumbnails/10.jpg)

EpidermisEpidermis Consists of several layers of stratified
squamous (scale like) epithelium: basal layer — innermost layer
basal cells are constantly being pushed up, moving older cells to the surface
melanocytes — produce pigment (melanin) which gives color to the skin
squamous layer — outermost layer

Dermis (Corium)Dermis (Corium) Connective tissue layer
Contains: blood and lymphatic vessels nerve and nerve endings glands hair follicles network of elastic and collagen fibers (gives
skin elasticity and toughness)

Subcutaneous LayerSubcutaneous Layer Layer below the dermis
Composed of loose connective tissue and adipose (fatty) tissue

LesionsLesions Areas of pathologically altered tissue
Two types: Primary
Primary lesions are physical changes in the skin considered to be caused directly by the disease process. Types of primary lesions are rarely specific to a single disease entity.
Secondary Secondary lesions may evolve from primary lesions, or may
be caused by external forces such as scratching, trauma, infection, or the healing process. The distinction between a primary and secondary lesion is not always clear.

Primary Lesions: pg Primary Lesions: pg 111-112111-112
Lesions arising from previously normal skin Flat, nonpalpable changes in skin color: macule, patch
Elevated, palpable, solid mass: papule, wheal
Elevation formed by fluid within a cavity:
vesicle, bulla, pustule

Secondary Lesions: Secondary Lesions: pg112-114pg112-114
Lesions that result in changes in primary lesions
Types: Loss of skin surface: erosion, ulcer, excoriation, fissure
Material on skin surface: scale, crust
Other secondary lesions:
keloid, nevus, verruca
