Epithelial Tissue has three surfaces, they are:

________free smooth and reduce friction, have microvilli to increase surface area for ABSORPTION and SECRETION

________________specialized structures for sensation and absorption.

____________ membrane connects the basal surface to other tissues

• A.

  True

• B.

  False

___________ Membrances are: -composed of many things mainly collagen. -Surface marker guides cell migration during tissue repair. -Has several layers, depending on the organ. -Can act as a filter in the nephron (Kidney)

Epithelial Tissue: -Offers ______ and provides a barrier. -selective _________ of stubstances -__________ -__________

What are the four types of cell connections?

____________ disk shaped regions of adjacent cell membranes; found in areas that are subjected to stress. They are very tough to break.

____________: half of a desmosome; attaches an apithelial cell to the basement membrane

_____________ junctions joins the entire cirfumfrence of adjacent cells together, forms a permeability barrier.

________ junctions protein channels for intercellular communication. -allow ions and small molecules to pass through. -coordinate functions of cardiac and smooth muscle.

Where are cell connections found?

Cell _______ functions are to, form permeability layers, bind cells together, provide mechanism for intercellular communication.

The two basic types of glands are endorcrine and exocrine.

• A.

  True

• B.

  False

_________ glands have no ducts; produce hormones that diffuse through the basement membrane.

________ ducts form open contact with the exterior.
