Chapter 4: The Tissue Level of Organization
Types of tissue
Connective tissue: fills internal space, provides structural support for other tissues , transport material within the body and stores energy
Muscle tissue: is specialized for contraction and includes the skeletal muscles of the body, the muscle of the heart , and the muscular was of hallow organs
Epithelial tissue: covers exposed surfaces , lines internal passageways and chambers, and forms glands
function
provide sensation
controls permeability
provides physical pretection
produce specialized secretion
characteristics
cellularity
attachment
avascularity
regeneration
polarity
Nervous tissue: carries information from one part of the body to another in the form of electrical impulses
Cell shape and numbering
simple epithelium
one layer of cells
stratified epithelium
more than one layer
cuboidal
box shaped
columnar
rectangle shaped
