Front Back
voluntary muscle tissue
skeletal muscle 
Forms inner lining of trachea
pseudostratified columnar
dry, dead cell material on skin surface
space inside a hollow organ or blood vessel
space in which chondrocytes or osteocytes reside
cell that produces mucus
goblet cell
hair-like tufts that sweep material along cell surface
forms lining of kidney tubules
simple cuboidal
specialized connections between cardiac muscle tissues
intercalated discs 
provides sturdy support for trachea, larynx, and nose
hyaline cartilage
Forms serous membranes
simple squamous
light and dark banding seen in some muscle tissue 
simple squamous epithelial characteristics
one layer thick, "fried egg" from apical view, irregular shape with nucleus hanging toward side
simple squamous epithelial locations found

absorption and secretion
simple cuboidal found 
kidney tubules
simple columnar characteristics
single layer of tall, narrow cells; elongated oval shaped nuclei found in basal half of cell
simple columnar functions
simple columnar found 
inner lining of stomach and intestines
pseudostratified columnar
looks multilayered, some cells don't reach free surface, but all reach basal membrane. Often with goblet cells and cilia
pseudostratified columnar found
respiratory tract
pseudostratified columnar functions
secrete and propel mucus
transitional epithelial characteristics 
"bunny ear," nucleus toward bottom with rounded tops, relaxes and stretches as transitions from one type to another
transitional epithelial functions
stretch to allow filling of urinary tract
transitional epithelial found
urinary tract, bladder
stratified squamous epithelial characteristics
multiple cell layers deep, increasingly flat and scaly toward surface; nonkeratinized same but without surface layer of dead cells
stratified squamous epithelial keratinized found
epidermis (palms and soles especially heavily keratinized)
stratified squamous epithelial keratinized function
resists abrasion, retards water loss through skin
stratified squamous epithelial nonkeratinized function
resist abrasion and penetration by pathogenic organisms
stratified squamous epithelial nonkeratinized found
tongue, vagina
stratified cuboidal epithelium characteristics
two or more layers of cube shaped cells
stratified cuboidal epithelium found
egg-producing vesicles of ovaries and sperm-producing ducts of testis
Areolar tissue characteristics
loose arrangement of collagenous and elastic fibers, scattered cells, many blood vessels
areolar tissue found
underlying epithelia
areolar tissue function
loosely bind epithelia to deeper tissue, allows passage of nerves and blood vessels through other tissues
reticular tissue characteristics
loose network of reticular fibers and cells, with leukocytes and other blood cells
reticular tissue found
lymph nodes, spleen
reticular tissue functions
framework for soft organs

adipose tissue function
energy storage, cushioning
adipose tissue found
subcutaneous fat beneath skin
dense regular connective tissue characteristics
densely packed wavy collagen fibers, with ground substance and some nuclei
dense regular connective tissue found
tendons and ligaments
dense regular connective tissue function
bind bones and muscles
dense irregular connective tissue characteristics
densely packed collagen fibers running in random direction, few visible cells, few blood vessels
dense irregular connective tissue found
deep portion of dermis
dense irregular connective tissue function
durable, withstand stresses to body
hyaline cartilage characteristics
clear, gassy matrix with 'hyena spots' and doubled nuclei clusters
hyaline cartilage found

skeletal muscle characteristics
striated, voluntary, long, unbranched with multiple nuclei
cardiac muscle characteristics
striated, interwoven, single nuclei per cell and intercalated discs, involuntary
smooth muscle characteristics
nonstriated, involuntary, overlapping cells with single nuclei elongated
goblet cell
cell that stores and secretes mucus 
cartilage cells
extracellular material in connective tissue
on the surface view from the top
at the bottom, view from below
basal or basement 
3 things to consider when classifying tissues
shape, layers, and location of nuclei
cartilage cell; former chondroblast that has become enclosed in a lacuna in the cartilage matrix
predominant fibers in reticular tissue
reticular fiber
ground substance
gelatinous fluid that absorbs compressive forces and protects delicate cells from injury. Found in space around cells and fibers in connective tissue
large cells that are thin and wispy, produce the fibers and ground substance that form matrix of tissue
