Classification of Tissue

Name Lab Time/Date Key EXERCISE 5 Classification of Tissues Tissue Structure and Function: General Review 1. Define tissue: Groups of Cells that are Sterilue a Struchice and function 2. Use the key choices to identify the major tissue types described below. (Some choices may be used more than once.) Key connective epithelium muscular nervous Epitheliom 1. lines body cavities and covers the body's external surface muscle 2. pumps blood, flushes urine out of the body, allows one to swing a bat nenraus 3. transmits waves of excitation. Connective 4. anchors and packages body organs epithelium 5. cells may absorb, protect, or form a filtering membrane muscle 6. most involved in regulating body functions quickly Connective 7. major function is to contract Connective 8. the most durable tissue type 9. abundant nonliving extracellular matrix nervous 10. forms nerves REVIEW SHEET Epithelial Tissue 3. On what bases are epithelial tissues clasified? Arrangement (#ol layers) Shape 4. How is the function of an epithelium reflected in its arrangement? function to form linings. reflicted in arrangement of fitting closely tegithir to fum mtact sheets of cells 5. Where is ciliated epithelium found? Lines trachen, most of upore respicatory tract What role does it play? Cia helps mine sulastunts aluy the Surface of the cell 50 Review Sheet 5 6. Transitional epithelium is actually stratified squamous epithelium, but there is something special about it. How does it differ structurally from other stratified squamous epithelia? cf Looks mar cubredel on Columner at the bottom (basal layer) so that it can streton How does this structural difference refleet its function in the body? Has the ability to slide over te another to allow the eager to be stretchiel 7. Use the key choices to respond to the following. (Some choices may be used more than once.) Key pseudostratified ciliated columnar simple columnar simple cuboidal simple squamous stratified squamous transitional Stratified sq. 1. best suited for areas subject to friction Beudo. Strat 01 2 propels substances across its surface Simplu Sq. 3. most suited for rapid diffusion Simple cuba dul 4. tubules of the kidney Pseudo. Strut CIL 5. lines much of the respiratory trict transitione! 6. stretches Simplu Collar 1. lines the small and large intestines Stratified Sq. 8. lining of the esophagus trunsitiuncul 9. lining of the bladder Simple 39. 10. alveolar sacs (air sacs) of the lungs Connective Tissue 8. What is the makeup of the matrix in connective tisatins'? Non-lilang 11/07 material gramed Substance & H₂O, Proteins, Carbs) fibers (Collagen, elastic, reticularl 9. How are the functions of connective tissue reflected in its structure? Protection (Joints) support and to bind other tissues togethe matris for stregath and fibers for Support 10. Using the key, choose the best response to identify the connective tissues described below. Key: adipose connective tissue areolar connective tissue dense fibrous connective tissue dense fibrous ossears areolar hyaline Ryaline osseous 6. matrix hard; provides levers for muscles to act on adipuse 7. insulates against heat loss, provides reserve fuel fiorecartilage Muscle Tissue reticular connective tissue hyaline cartilage osseous tissue 1 attaches bones to bones and muscles to bones 2. forms your hip bore fibrocartilage blood 3. composes basement membranes, a soft packaging tissue with a jellylike matrix 4. forms the larynx and the costal cartilages of the ribs 5. firm matrix heavily invaded with fibers, appears glassy and smooth 8. makes up the intervertebral dises 11. The terms and phrases in the key relate to the muscle tissues. For each of the three muscle tissues, select the terms or phrases that characterize it, and write the corresponding letter of each term on the answer line. Key: a. striated f. voluntary b. branching cells g. involuntary c. spindle-shapod cells h. one nucleus d. cylindrical cells 1. many nuclei e. active during birth j. forms heart walls Skeletal muscle: a, d, f,i, k Cardiac muscle: a, b, d, e, g, h, I Smooth muscle: Ceghm, o Nervous Tissue 12. In what ways are nerve cells similar to other cells? How are they different? lang extensions (aven & dunclates) k. attached to boncs 1. intercalated dises m. in wall of bladder and stomach n. moves limbs, produces smiles . arranged in sheets nucleus containing cell w/ cyteplasm How does the special structure of a neuron relate to its fonction? Allows a single heures to conduct an impulse over ling distances.
