Gross Anatomy- Integument And Dermatomes

Front 1

Human Integument Layers

Back 1

Epidermis and Dermis

Front 2

-Stratified squomous (flat) epithelium resting on a connective tissue base.
-Avascular
-Outer layer of human integument
-Cells are tightly adherent

Back 2

Epidermis

Front 3

Deepest layer of the epidermis composed of mitotically active cells (cells that are always dividing)

Back 3

Stratum Germinativum (stratum basale)

Front 4

-Outermost and visible layer of the epidermis containing dead keratinized cells
-High mitotic activity and layer most likely to contain malignant cells

Back 4

Stratum Corneum

Front 5

-Interface between epidermis and dermis
-Noncellular layer of glycoproteins found on epithelial/connective tissue interfaces
-Secretory product of eptihelium and connective tissue
-Nutrients and oxygen pass through from dermis to epiderms

Back 5

Basement Membrane

Front 6

Anchors the cells in the stratum germinativum to the basement membrane

Back 6

Hemidesmosomes

Front 7

Cell characterized for cell adhesion

Back 7

Desmosome

Front 8

-Deep layer of integument
-Dense irregular connective tissue composed primarily of tough collogen (protein fibers) and varying amounts of elatic fibers, which are arranged in irregular bundles
-what leather is derived from in animals

Back 8

Dermis

Front 9

Secrete and maintin collogen fibers in the dermis

Back 9

Fibrocytes

Front 10

Pigment-producing cells

Back 10

Melanocytes

Front 11

Scattered cells found in the Dermis

Back 11

Fibrocytes, Macrophages, and Melanocytes

Front 12

Other features of the Dermis

Back 12

-Vascularized with capillary plexus
-Contains epidermal derivatives:glands and hair folllicles

Front 13

-Epidermis + Dermis =
-Only found on palms of hand and soles of feet

Back 13

Skin Thickness

Front 14

-Layer of connective tissue on which the integument rests
-Consists of loose bundles of collogen and elastic fibers
-Site of aggregation of lipocytes
-Contains and supports cutaneous nerves and blood vessles

Back 14

Superficial Fascia, Subcutaneous Tissue,
subQ,
Hypodermis
