SLCC Anatomy, histology flashcards

QuestionAnswer
What are the common characteristics of Epithelial Tissue? 1. Celularity - little ground substance, cells bound by cell junctions 2. Polarity - apical/basal surface 3. Attachment -- basement membrane 4. Avascularity --> nutrients obtained by diffusion or absorption. 5. Regeneration --> mitosis of stem cells
What are the common functions of Epithelial tissue? 1. physical protection 2. "gatekeepers" control permeability 3. Provide sensation --> large nerve supply 4. Produce specialized secretions (gland cells)
What is the basement membrane of an Epithelial cell and what is it composed of? Composition = 1. basal lamina: collagen fibers, protein and carbohydrates secreted by the basal surface of the epithelial cell. 2. reticular lamina = protein fibers and carbohydrates secretes by the connective tissue cells.
What is the function of the basement membrane of an epithelial tissue? 1. physical support, anchored to the conective tissue. 2. barrier - regulate movement of large molecules between epithelium and connective tissue.
What is a tight junction and its function? adjacent cell membranes are tightly bound at apical surface by interlocking membrane protiens (at lipid portions of membrane) Prevent passage of H2O and solutes between cells.
What is a desmosome and its function? CAM's and proteoglycons (protein fibers) link the opposing cell membranes--connected to cytoskeloton = really strong. hemidesmosomes = 1/2 desmosome that anchor cell to basal lamina
What is a Gap Junction and its function? two cells held together by a link of connexons (carrier proteins) allows a passage or pore to allow solutes and other nutrients to pass from cell to cell.
Simple Squamous Epithelium (structure, function, location) * this, flat, somewhat irregular --delicate * easy diffusion, osmois, or absorption/secretion * located in protected regions where diffusion/absorption takes place, alveoli, lining of ventral cavties, lining of heart and blood vessels.
Mesothelium: define Simple squamous epithelium that specifically lines the ventral body cavities: pleura, peritoneum, and pericardium
Endothelium: define simple squamous epithelium that specifically lines the inner surface of the heart and all the blood vessels. the lacunae of the vessels.
Simple Cuboidal Epithelium (Structure, function, location) * tall as wide, "hexagonal boxes"; distance between nuclei = height of cell. * limited protection, BUT good for secretion and absorption

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
