Tissue Characteristics

Anatomy Lecture 9/22

what systems/organs does epithelial tissue line?

skin, trachea, bronchi, alveoli, digestive tract, esophagus, stomach, intestines, oral cavity, urinary and reproductive systems, surface of the eye, back of the eye, etc..

where would you find ET?

anywhere that comes into contact with fluid or air

describe ET tissue and it’s cells:

• very little extracellular fluid

• cells are packed tightly together

• the cells attach to the basement membrane

• some fibers

whats the purpose of Connective tissue?

to mechanically or functionally connect things; in most instances, it’s mechanical

give an example of functional CT:

blood

describe CT and it’s cells:

• cells are suspended in an extracellular matrix (ground substance)

• always has fibers

• some CT has no fluid (bone) and some are all fluid (blood)

describe Muscle tissue and it’s cells:

• very few fibers or fluid

• cells are packing tightly together

whats the purpose of muscle tissue?

change their shape and in doing so, create mechanical force

describe nervous tissue and it’s cells:

• very simplistic

• very little fiber or structure

• The cells are neurons and glia

• Cells are suspended in an aqueous puddle

whats the purpose of NT?

to generate and process information
