Which one of the following is not one of the four main tissue categories?

  1. A) muscle tissue
  2. B) neural tissue
  3. C) osseous tissue
  4. D) connective tissue
  5. E) epithelial tissue

Osseous tissue

2

Functions of epithelia include all of the following except

  1. A) providing physical protection.
  2. B) controlling permeability.
  3. C) absorption.
  4. D) producing specialized secretions.
  5. E) supporting muscle cells.

Supporting Muscle Cells

3

Epithelial cells that are adapted for absorption usually have ________ at their free surface.

microvilli

4

A type of intercellular junction that stops materials from crossing an epithelium between cells is called a(n)

tight junction.

5

Dead skin cells are shed in thin sheets because they are held together by "spots" of proteoglycan reinforced by intermediate filaments. Such strong intercellular connections are called

desmosomes

6

Epithelial cells exhibit modifications that adapt them for

secretion

7

Epithelium is connected to underlying connective tissue by

a basement membrane.

8

Epithelia specialized for providing sensations of smell, taste, sight, equilibrium, and hearing are known as

neuroepithelia

9

Transitional epithelium is found

lining the urinary bladder.

10

The heart and blood vessels are lined by ________ epithelium.

simple squamous

11

You would find pseudostratified columnar epithelium lining the

trachea

12

Secretions through a duct might provide ________, whereas ductless secretions act as ________.

enzymes; hormones

13

The function of simple cuboidal epithelium is

absorption and secretion.

14

The pancreas produces ________ secretions.

exocrine and endocrine

15

Which of the following connective tissue cells produces collagen?

fibroblasts

16

The color distinction between white fat and brown fat exists because brown fat

is highly vascular.

17

Cells that engulf bacteria or cell debris within loose connective tissue are

macrophages

18

Cells that respond to injury by dividing to assist in connective tissue repair are

mesenchymal cells.

19

Tissue that is specialized for the conduction of electrical impulses is ________ tissue.

neural

20

During an inflammatory response to injury, which of the following is the least likely in the region of the injury?

  1. A) increase in basophils
  2. B) increase in histamine
  3. C) increase in blood flow
  4. D) cold, pale skin
  5. E) swelling

Cold, pale skin

21

The body's first tissue response to any injury is

inflammation.

22

During the inflammatory process, blood vessels dilate. What does this accomplish?

It allows for increased blood flow for delivery of nutrients, oxygen, and defense cells and proteins and for the removal of waste products and debris from the site of injury.
