Anatomy Chapter 3 Vocab - List #1

Tissues

groups of similar cells specialized to perform a specific function; primary tissue types are epithelial, connective, muscle, and nervous tissues

Apical surface

free (unattached) surface or edge; exposed to the body's exterior or to the cavity of an internal organ

epithelium

the lining, covering, and glandular tissue of the body

Basement membrane

a thin layer of extracellular material to which epithelial cells are attached in mucosa surfaces

Simple epithelium

one layer of cells

Stratified epithelium

more than one cell layer

Squamous epithelium

flat, scalelike cells; fit closely together like floor tiles

Serous membrane/ serosa

epithelial membrane that lines a cavity without an opening to the outside of the body

Simple cuboidal epithelium

one layer of cuboidal cells resting on a basement membrane; common in glands and their ducts

Simple columnar epithelium

a single layer of tall cells that fit closely together

Goblet cells

individual cells that produce mucus

mucosae/mucous membrane

epithelial membranes that line body cavities open to the body exterior

Pseudostratified columnar epithelium

nuclei appear at different heights which gives the false impression that it is stratified

Stratified squamous epithelium

several layers of squamous cells

Stratified squamous epithelium

typically has just two cell layers with the surface cells being cuboidal shape

Stratified columnar epithelium

columnar cells, but its base cells vary in size and shape

Transitional epithelium

highly modified, stratified squamous epithelium; forms the lining of unirany organs

Gland

one or more cells that make and secrete a particular product

Secretion

the product from a gland; typically contains protein molecules in an aqueous (water-based) fluid

endocrine glands

lose their connection to the surface, ductless glands; hormones

Exocrine glands

retain ducts to the epithelial surface; sweat, oil glands, liver, and pancreas

Connective tissue

connects body parts

Extracellular matrix

nonliving material in connective tissue consisting of ground substance and fibers that separate the living cells
