tissue

group of cells similar in structure & function

four

# of types of tissue

epithelial tissue

lines organs, cover bdoy surface & are found in glandular tissue

avascular

lacking blood vessels

true

epithelial tissue is avascular

one

# of layers of cells in simple epithelial

stratified epithelial tissue

epithelial tissue with two or more cell layers

pseudostratified epithelial tissue

tissue with cilia

respiratory system

where pseudostratified epithelium is found

squamous epithelial tissue

flattened cells with broad & thin nuclei

cuboidal epithelial tissue

cube-shaped cells with central nuclei

columnar epithelial tissue

column-shaped cells with nucleus near bottom of the membrane

transitional epithelial tissue

shape-changing cells found in urinary bladder

air sacs (alveoli) & blood vessels

where simple squamous epithelial tissue is found

ovaries, kidney tubules & gland ducts

where simple cuboidal epithelial tissue is found

uterus & digestive tract

where simple columnar epithelial tissue is found

mouth, esophagus, tongue & skin

where stratified squamous epithelial tissue is found

brain, spinal column & peripheral nerves

where nervous tissue is found

well vascularized

connective tissue is…

loose connective tissue

loosely arranged fibers; three types

areolar connective tissue

most abundant type of loose tissue

underlying tissues

what does areolar tissue bind skin to?

adipose connective tissue

fat tissue that cushions, insulates & energizes body

reticular connective tissue

loose tissue that supports walls of internal organs

dense connective tissue

tissue w/ strong collagenous fibers

tendons, ligaments, sclera & dermis

where dense connective tissue is found

true

bone is a rigid connective tissue

false

blood is not a connective tissue

cartilage

connective tissue made of collagen & elastic fibers

false

cartilage receives direct blood supply & is quick to heal

skeletal muscle tissue

multi-nucleated, striated, voluntary, heat-producing muscle tissue

smooth muscle tissue

small, cigar-shaped, uni-nucleated, un-striated muscle tissue found lining organs

cardiac muscle tissue

branching, striated, involuntary muscle tissue
