5 Flashcards
Tissue
One or more cells that work together to perform a specific function
Four main tissue types
Epithelial, connective, nervous, muscular
Apical
Outer surface, unattached
Basal
Inner surface, attached
Protection, secretion, absorption
Packed with sheets of cells (simple or stratified)
Squamous, cuboidal, columnar shapes
Epithelial tissue
Connect, support, protection
Most abundant tissue
Variable appearance
Very few cells, lots of ECM
Matrix has protein fibers (reticular, elastic, collagen)
Connective tissue
Movement
Packed with cells
Cells are either thin and long or thin and short
Excitable cells
Muscle tissue
Send and receive messages (communication) or support communication
Packed with cells, contain neurons or neuroglia (supporting cells)
Nervous tissue
Attaches epithelium to connective tissue
Basement membrane
Fibers found in connective tissue matrix
Reticular, elastic, collagen
Hwy does cartilage heal slow
Low blood flow
Cardiac muscle has
Striations and intercalated discs
