Given these characteristics:
1. capable of contraction
2. covers free body surfaces
3. lacks blood vessels
4. composes various glands
5. anchored to connective tissue by a basement membrane

Which of these are characterics of epithelial tissues?

e. 2,3,4,5

2

Which of these embryonic germ layers gives rise to muscle, bone, and blood vessels?

c. mesoderm

3

A tissue that covers a surface, is one cell layer thick, and is composed of flat cells is

a. simple squamous epithelium

4

Stratified epithelium is usually found in areas of the body where the principal activity is

b. protection

5

Which of these characteristics do NOT describe nonkeratinized stratified squamous epithelium?

d. found in the skin

so it has many layers of cells, flat surface cells, living surface cells, and outer layers covered by fluid

6

In parts of the body where considerable expansion occurs, such as the urinary bladder, which type of epithelium would you expect to find?

c. transitional

7

Epithelial cells with microvilli are most likely found

d. lining the small intestine.

8

Pseudostratified ciliated columnar epithelium can be found lining the

b. trachea

9

A type of cell connection whose only function is to prevent the cells from coming apart is a

a. desmosome

10

The glands that lose their connection with epithelium during embryonic development and secrete their cellular products into the bloodstream are called ____________ glands.

b. endocrine

11

A _____________ gland has a duct that branches repeatedly, and the ducts end in saclike structures.

e. merocrine

12

The fibers in dense connective tissue are produced by

a. fibroblasts

13

Mesenchymal cells

d. All of these are correct.

so they form ebryonic connective tissue, give rise to all adult connective tissues, in adults produce new connective tissue cells in response to injury.

14

A tissue with a large number of collagen fibers organized parallel to each other would most likely be found in

b. a tendon

15

Extremely delicate fibers that make up the framework for organs such as the liver, spleen, and lymph nodes are

b. reticular fibers

16

In which of these locations is dense irregular elastic connective tissue found?

d. large arteries

17

Which of these is NOT true of adipose tissue?

d. Brown adipose is found only in older adults.

so it is the site of energy storage, it is a type of connective tissue, it acts as a protective cushion, and it functions as a heat insulator.

18

Which of these types of connective tissue has the smalles amount of extracellular matrix?

a. adipose

19

Fibrocartilage is found

e. between vertebrae

20

A tissue composed of cells located in lacunae surrounded by a hard matrix of hydroxyapatite is

b. bone

21

Which of these characteristics apply to smooth muscle?

c. unstriated, involuntary

22

Which of these statements about nervous tissue is not true?

c. bipolar neurons have two axons.

so neurons have cytoplasmic extensions called axons, electrical signals are conducted along axons, neurons are nourished and protected by neuroglia, and dendrites receive electrical signals and conduct them toward the cell body.

23

The linings of the digestive, respiratory, excretory, and reproductive passages are composed of

b. mucous membranes.

24

Chemical mediators

c. initiate processes that lead to edema

25

Which of these types of cells are labile?

b. skin

26

Permanent cells

d. are usually replaced by a different cell type if they are destroyed.
