Anatomy Ch. 4&5

Front 1

Tissues

Back 1

groups of similar cells and extracellular products that carry out a common function, such as providing protection or facilitating body movement

Front 2

Histoloy

Back 2

study of tissues and their relationships within organs

Front 3

Four principle types of tissues in the body

Back 3

Epithelial, Connective, Muscle, and Nervous

Front 4

Three primary germ layers are

Back 4

Ectoderm, Mesoderm, and endoderm

Front 5

Epithelial Tissue

Back 5

lines every body surface and all body cavities

Front 6

Basement Membrane

Back 6

thin extracellular layer between the epithelium and the underlying connective tissue

Front 7

Basal Lamina

Back 7

contains collagen fibers as well as protein and carbohydrate macromolecules that are secreted by the cells of the epithelium

Front 8

Simple Epithelium

Back 8

one cell layer thick, and all of these epithelial cells are in direct contact with the basement membrane

Front 9

Stratified Epithelium

Back 9

two or more cell layers thick; only the deepest layer directly attaches to the basement membrane

Front 10

Pseudostratified Epithelium

Back 10

layered; cells nuclei are distributed at different levels between the apical and basal surfaces. Attached to basement membrane, although some do not reach its apical surface

Front 11

Squamous Cells

Back 11

flat, wide, and somewhat irregular in shape

Front 12

Cuboidal Cells

Back 12

about as tall as they are wide. Are not perfect cubes because edges are rounded

Front 13

Columnar Cells

Back 13

slender and taller than they are wide. look like a hexagon

Front 14

Simple Squamous Epithelium

Back 14

one layer of flattened, tightly bound cells

Front 15

Endothelium

Back 15

epithelium that lines the lumen of the blood and lymphatic vessels and that heart and its chambers

Front 16

Mesothelium

Back 16

simple squamous epithelium that lines the internal walls of the pericardial, pleural, and peritoneal cavities as well as external surfaces of the visceral organs of the cavities

Front 17

Simple Cuboidal Epithelium

Back 17

one layer of tightly bound, cube-shaped cells

Front 18

Simple Columnar Epithelium

Back 18

one layer of tightly bound, tall shaped cells

Front 19

Stratified Squamous Epithelium

Back 19

Many layers thick; cells in outer layers are dead, flat, and contain keratin. In nonkeratinized they are alive, flat, and moist

Front 20

Stratified Cuboidal Epithelium

Back 20

Two or more layers of cells; apical layer of cells is cube-shaped

Front 21

Stratified Columnar

Back 21

two or more layers of cells;cells in apical layer are columnar-shaped

Front 22

Pseudostratified Columnar Epithelium

Back 22

one layer of cells of varying heights; all cells attach to basement membrane; ciliated form contains cilia and goblet cells; nonciliated form lacks cilia and goblet cells

Front 23

Transitional Epithelium

Back 23

multiple layers of cuboidal and rounded cells, or flattened cells; some cells may be binucleated

Front 24

Glands

Back 24

individual cells or multicellular organs composed predominantly of epithelial tissue

Front 25

Endocrine Glands

Back 25

lack ducts and secrete their products directly into the interstitial fluid and bloodstream

Front 26

Exocrine Glands

Back 26

originate from an invagination of epithelium that burrows into deeper connective tissues. these glands usually maintain their contract with epithelial surface by means of a duct

Front 27

Duct

Back 27

an epithelium-lined tube through which secretions of the gland are discharged onto the epithelial surface

Front 28

Multicelluar Exocrine Glands may be classified according to three criteria:

Back 28

form and structure, type of secretion, or method of secretion
