front 14 Describe five general characteristics of epithelial tissue. | back 14 Polarity, Cellularity, Supported by Connective tissue, Avascularity and Regeneration |
front 15 On what basis are epithelial tissues classified? | back 15 arrangement or relative number of layers and cell shape |
front 16 List five major functions of epithelium in the body, and give examples of each. | back 16 1. protection; epithelium covering body surface protects against bacterial invasion and chemical damage.
|
front 17 How does the function of stratified epithelia differ from the function of simple epithelia? | back 17 Simple means that there is only one layer of these cells, not as much protection as stratified which indicates several layers of cells. Stratified epithelia are named according to the cells at the apical surface of the epithelial membrane, not those resting on a basement membrane like the simple epithelia. |
front 18 Where is ciliated epithelium found? What role does it play? | back 18 Can be found in the lining of the trachea, most of the upper respiratory tract. There role is to keep mucus and any other debris from entering the lower reaches of the lung tissue by moving in a upward direction. |
front 19 Transitional epithelium is actually stratified squamous epithelium with special characteristics. How does it differ structurally from other stratified squamous epithelia? How does the structural difference support its function? | back 19 its structure is different in that it is rounded, or "plump" cells. Its structural difference supports in function in that it has the ability to slide over one another to allow the organ to be stretched. |
front 20 How do the endocrine and exocrine glands differ in structure and function? | back 20 Endocrine glands are ductless, and there function is to release all hormones into the extracellular fluid where they enter blood stream and lymphatic vessels. But Exocrine glands have ducts, and they secrete through the ducts to an epithelial surface. |
front 21 Lining of the esophagus | back 21 Stratified Squamous |
front 22 Lining of the stomach | back 22 Simple Columnar |
front 23 Alveolar Sac of Lungs | back 23 Simple squamous |
front 24 Tubules of the kidney | back 24 Simple Cuboidal |
front 25 Epidermis of the skin | back 25 Stratified squamous |
front 26 Lining of bladder; peculiar cells that have the ability to slide over each other | back 26 Transitional |
front 27 Forms the thin serous membranes; a single layer of flattened cells. | back 27 Simple squamous |
front 28 What are three general characteristics of connective tissues? | back 28 1. With a few exceptions, connective tissues have a rich supply of blood vessels.
|
front 29 What functions are performed by connective tissue? | back 29 protection, support, and bind together tissues of the body. |
front 30 How are the functions of connective tissue reflected in its structure? | back 30 there is a wide variety in the structures of connective tissue. This is relected in the wide variety of functions they perfrom. Also, the large amount of nonliving matrix seen provides the strength needed to protect the body and carry out the normal functions of the body. |
front 31 attaches bones to bones and muscles to bones | back 31 dense connective tissue |
front 32 acts as a storage depot for fat | back 32 adipose |
front 33 the dermis of the skin | back 33 dense |
front 34 makes up the intervertebral discs | back 34 fibrocartilage |
front 35 forms the hip bone | back 35 osseous |
front 36 composes basement membranes; a soft packaging tissue with a jellylike matrix | back 36 areolar |
front 37 forms the larynx the costal cartilages of the ribs and the embryonic skeleton | back 37 hyaline cartilage |
front 38 provides a flexible framework for the external ear | back 38 elastic cartilage |
front 39 firm structurally amorphous matrix heavily invaded with fibers; appears glassy and smooth | back 39 hyaline cartilage |
front 40 matrix hard owing to calcium salts; provides levers for muscles to act on | back 40 osseous |
front 41 insulates against heat loss | back 41 adipose connective tissue |
front 42 walls of large arteries | back 42 elastic |
front 43 Why do adipose cells remind people of a ring with a single jewel? | back 43 they contain a large fat-filled vacuole occupying most of the cell volume. The nucleus is pushed to the periphery, giving the cell a "signet ring" appearance. |
front 44 What two physiological characteristics are highly developed in neurons, nerve cells? | back 44 irritablility and conductivity |
front 45 In what ways are neurons similar to other cells? | back 45 they constain a nucleus and the usual organelles. |
front 46 How are neurons and other cells different? | back 46 their cytoplasm is drawn out into long processes. |
front 47 Describe how the unique structure of a neuron relates to its function in the body | back 47 neurons conduct impulses over relatively long distances in the body. This is facilitated by their long cytoplasmic extensions. |
