<p> Unit 2: Histology - Study Guide</p><p>Know these things:</p><p> The four basic tissue types</p><p> Distinguishing characteristics of epithelial tissues</p><p> How epithelial tissues are classified & named</p><p> Pay attention to special characteristics of transitional & pseudostratified epithelial tissues</p><p> Glands – if branched or unbranched (simple/compound) and their shape (tubular/acinar)</p><p> Be able to describe the characteristics of endocrine & exocrine glands (this will be a short answer question on the test). Ducts, where substances are secreted, what type of substance, and how exocrine glands are classified.)</p><p> Characteristics of connective tissue</p><p> Major components of extracellular matrix of connective tissue</p><p> Functional characteristics of blood, bone, & all three cartilage types (fluid, strong & rigid, recoils…)</p><p> Know the three muscle types & how to tell them apart</p><p> Mediators of inflammation (there are two)</p><p> Results of mediators of inflammation (vasodilation of blood vessels, etc.)</p><p> Major symptoms of inflammation</p><p> Replacement vs. regeneration of cells</p><p> The type of tissue that first replaces a clot during tissue repair</p><p> The purpose of stratification</p><p> The difference between merocrine, apocrine, & holocrine exocrine glands</p><p> Function of goblet cells</p><p> Main function of simple squamous epithelium</p><p> What type of epithelial tissues would be found:</p><p>. Urinary bladder . lining of small intestine</p><p>. alveoli of lungs . outer layer of skin</p><p>. kidney tubules</p><p> What type of connective tissue is found: . External ear . Vocal cords</p><p>. Tendons & ligaments . Tissue beneath skin</p><p>. Covering ends of bones at joints . Shock-absorption in knees, between vertebrae</p><p> Functions of cell connections: desmosomes, hemidesmosomes, gap junctions, tight junctions</p><p> What these cell types do: clast, blast, & cyte, mast cells, macrophages</p><p> Functions of fiber types: reticular, elastic, collagen</p><p> The difference between labile, stable, & permanent cell types (regarding division)</p><p> Be able to draw a neuron & label it (soma, dendrites, axon, nucleus , and which way an action potential flows through it ).</p><p> The two types of phagocytic cells involved in tissue repair - macrophages & neutrophils (WBC)</p><p> Heavy smoking damages the ciliated cells in the trachea – what would happen if cells that replace the damaged ones do not have cilia? (Buildup of mucus & foreign particles resulting in increased coughing).</p>
