Chapter 5 Tissue B.B.C.C.M Flashcards
epithelial tissue layers
-simple
-stratified
epithelial tissue shapes
-squamous
-cuboidal
-columnar
allows materials to cross surface via DIFFUSION OR FILTRATION
-blood vessels
-alveoli
-kidney
-endothelium
-serous membranes
simple squamous epithelial tissue
ABSORPTION & SECRETION
-Kidney tubules
-Glands ( mammary, liver, thyroid, salivary )
simple cuboidal
ABSORPTION & SECRETION OF MUCUS, ENZYMES
NON-CILIATED-digestive tract
CILIATED- bronchi, uterus
simple columnar
SECRETES & PROPELS MUCUS
-RESPIRATORY TRACT( nasal cavity to bronchi, trachea)
-male urethra
pseudostratified ciliated columnar epithelial tissue
Protects underlying tissues from abrasion
-KERATINIZED ( epidermis)
-NON KERATINIZED (oral mucosa, vagina, esophagus, anal canal
stratified squamous epithelial tissue
stretches to allow filling of the bladder
-urinary tract (bladder, urethra, ureter)
transitional epithelial tissue
give 1 location for simple squamous epithelial tissue
Kidney
or
B.A.K.E.S
-blood vessels
-alveoli
-kidney
-endothelium
-serous membranes
give 1 location for simple cuboidal epithelial tissue
Kidney tubules
or
K.G
-kidney tubules
-glands (malts: mammary, liver, thyroid, salivary)
give 1 location for simple columnar epithelial tissue
remember: colcil
non ciliated- digestive tract (small intestine)
ciliated- bronchi
give 1 location for stratified squamous epithelial tissue
remember: ss & k
keratinized- epidermis
non keratinized- vagina
give 1 location for pseudostratified ciliated columnar epithelial tissue
remember: colcil, pseudo always columnar
Respiratory tract
-trachea
-nasal cavity to bronchi
give 1 location for transitional epithelial tissue
Urinary tract
-urethra
-ureter
-bladder
internal spaces within organs
lumens
epithelial cells have polarity what are they
apical layer
basal layer
the epithelial cells are packed together tightly with little or no intercellular material between them
cellularity
epithelial cells are so tightly packed that blood vessels cannot pass between them
avascular
sheet like epithelial tissues which cover body and organ surfaces
covering and lining epithelia
clump of epithelial cells which form glands secreting various products
glandular epithelia
the sides of the tissues are different
the sides of the tissues are different
the exposed or unattached side of the tissue is called
apical surface
the side attached to deeper connective tissue
basal surface
thin layer of protein that connects the basal surface of the epithelial tissue to the connective tissue
basement membrane
epithelial cells are attached to adjacent epithelial cells
lateral surface
single celled exocrine glands which produce and secrete mucus
goblet cells
the cells of the squamous cell layers are filled with a tough protein (keratin)
keratinized
tough protein which provides an added protective benefit
keratin
water based substance containing inorganic and organic compounds
ground substance
composed of collagen, convey strength and flexibility to a tissue
collagen fibers
composed of elastin, convey elasticity
elastic fibers
composed of elastin, convey elasticity
composed of collagen, are branching fibers that provide internal support for soft tissues
reticular fibers
most abundant cell type in loose connective tissue
fibroblast
