4 primary types of tissues - Answersconnective, epithelial, nervous, muscular
sheets of cells that cover exterior surface, line internal cavities, and form certain glands -
Answersepithelial tissue
binds cells and organs of the body together, protection, support and integration of all body parts
- Answersconnective tissue
excitable, responds to stimulation and contracting to provide movement - Answersmuscle
tissue
excitable, propagation of electrochemical signals in the form of nerve pulses... -
Answersnervous tissue
brain, spinal cord, and nerves - Answersnervous tissue
heart, stomach, and musculature - Answersmuscle tissue
fat, bone, tendons - Answersconnective tissue
lining of GI tract and surface of skin - Answersepithelial tissue
characteristics of epithelial tissues - Answersavascular,
innervated,
high mitotic rate,
closely joined cells,
minimal intercellular material
surface of epithelial cells exposed to body cavity, lumen, internal organ, or exterior of body -
Answersapical surfaces
surfaces of epithelial cells that connect to neighboring cells - Answersbasal and lateral surfaces
surfaces of epithelial cells connected to connective tissue below - Answersreticular and basal
lamina surfaces
tiny finger-like projections on epithelial cells that increase surface area and help with
secretion/absorption (lines inner surface in GI tract) - Answersmicrovilli
mobile epithelial projections that beat back and forth to promote the movement of substances
and found on the surface of respiratory epithelium (trachea and bronchi) - Answerscilia
single layer of flattened epithelial cells that allows materials to pass through w/ diffusion and
, secretes lubricating substances, found in lining of heart, blood and lymph vessles -
Answerssimple squamous
secretes and absorbs, found in ducts and secretory proteins of small glands and kidney tubules
- Answerssimple cuboidal
absorbs and secretes mucus and enzymes (hydrochloric acid); ciliated tissue in larger
bronchioles, uterine tubes, and uterus; smooth are in GI tract, intestines, and bladder -
Answerssimple columnar
secretes and moves mucus; ciliated tissue that lines bronchi, trachea and upper respiratory
tract - Answerspseudostratified
protects against abrasion, lines esophagus, mouth, and vagina; contains keratin on skin where
possible dehydration is an issue; non-keratinized present in moist areas inside the body (vagina)
- Answersstratified squamous
protective tissue, found in sweat glands, salivary glands, and mammary glands -
Answersstratified cuboidal
secretes and protects, found in male and female urethrae and ducts of some glands -
Answersstratified columnar
allows urinary organs to expand and stretch, lines bladder, urethra, and ureters; ; tolerates
stretch and recoil - Answerstransitional
provides spaces to allow chemical ions and molecules to move directly from one cell to another
- Answersgap junctions
prevent the movement of material between cells - Answerstight junctions
link epithelial cells to surrounding structures - Answersdesmosomes
link epithelial cells to other epithelial cells - Answersspot desmosomes
link epithelial cells to underlying basement membrane - Answershemidesmosomes
epithelial glands that secrete hormones into blood - Answersendocrine glands
epithelial glands that secrete substances thru a duct into or out of the body - Answersexocrine
glands
thyroid and adrenal glands are which type of epithelial glands - Answersendocrine glands
sweat glands are which type of epithelial glands - Answersexocrine glands
type of exocrine glands that pack secretions composed of water, ions, and small molecules into
vesicles and release thru exocytosis - Answersmerocrine glands
