Flashcards in Tissues 1 Deck (25):
What 5 things are we made of?
What are the 4 tissue types?
What are the features of epithelia tissue?
Keeps cells connected
Good adaptive powers
Good regenerative powers
Define a desmosome (adhering junction).
Stick cells together and help keep the structure of the epithelia intact.
Define a tight junction (occulting junction).
Seal intercellular spaces and are waterproof so no space for water or other solutes.
Define a gap junction (communication junction).
For cell to cell communication.
Look like tight junctions but have a rosette of proteins called connectents which allows ions to travel through the cell.
Where does the epithelial sit?
On the connective tissue basement membrane.
What does BL and RL stand for?
Basal lamina and reticular lamina.
What is cilia?
Finger like projection from apical surface. Movement of mucas.
Where is the apical surface?
Opposite the basal lamina.
What is the tubulin skeleton arrangement?
9+2 arrangement of tubulin doublets.
What is microvilli?
Increased surface area of cell, are smaller than cilia and thinner. Supported by microfilaments and used for absorption.
What are the 3 types of simple epithelia?
What are the 3 types of stratified epithelia?
What is the odd type of epithelia?
What type of epithelia is the saliva gland made of?
Where is transitional stratified epithelia found?
Urinary bladder and uretha.
Link one cell to the extracellular matrix.
Collections of secretory epithelial cells and can be single or multicellular.
What are the features of connective tissue?
Structure/function defined by extracellular matrix
Liquid to solid matrix
What defines the tissues?
Extracellular matrix proteins.
Name 3 things made from connective tissue.
Blood (filled with alubins)
Adipose (mainly fat)
What are the features of muscle tissues?
Cytoplasm is packed with contractile apparatus
Long, thin cells
Shorten lengths, close down spaces
What are muscle tissues stuffed with?
Myosin, actin and mitochondria.
