Chapter 4

Question 1

Name the function of epithelial tissue.

.

Answer 1

.Provide physical protection.Control permeability. Provide sensation. Produce specialized secretions

Question 2

Name the function of connective tissue.

Answer 2

Establishing a structural framework for the body. Transporting fluids and dissolved materials. Protecting delicate organs. Supporting, surrounding and interconnecting other types of tissue. Storing energy, especially in the form of triglycerides. Defending the body from invading microorganism

Question 3

Name and explain the three components of Connective tissue

Answer 3

Specialized cells = some function in local maintenance, repair, energy storage and defend and repair damaged tissues. Extracellular protein fibers = collagen fibers; most common fiber, reticular fiber; thinner than collagen fibers, stabilized the position of organs, elastic fibers; after stretching they return to their original length

Question 4

Glands

Answer 4

collections of epithelial cells (or structures derived from epithelial cells) that produce secretions

Question 5

Endocrine glands

Answer 5

produce endocrine secretions called hormones, hormones enter the bloodstream for distribution throughout the body

Question 6

Exocrine gland

Answer 6

produce exocrine secretions, which are discharged onto the epithelial surface, most exocrine secretions reach the surface through tubular ducts

Question 7

Loose connective tissue

Answer 7

are the packing materials of the body, they fill spaces between organs, cushion and stabilize specialized cells in many organs, and support epithelia, example, areolar tissue, adipose tissue, and reticular tissue

Question 8

are the packing materials of the body, they fill spaces between organs, cushion and stabilize specialized cells in many organs, and support epithelia, example, areolar tissue, adipose tissue, and reticular tissue

Answer 8

collagen fibers are the dominant type of fiber in them, three types of regular connective tissue, irregular connective tissue, and elastic tissue

Question 9

White fat

Answer 9

most of the adipose tissue in the body, it has a pale, yellow-white color

Question 10

Brown fat

Answer 10

deep, rich color, when these cells are stimulated lipid breakdown speeds up, heat is absorbed by surrounding tissue

Question 11

Tendon

Answer 11

the dense regular connective tissue that attaches skeletal muscle to bones

Question 12

Ligaments

Answer 12

connect one bone to another or stabilize the positions of internal organs

Question 13

Ulcer

Answer 13

breaks in the lining of the stomach (mainly caused by Helicobacter pylori) or in the small intestine

Question 14

hyaline cartilage

Answer 14

the most common type of cartilage, found in ribs and sternum, nasal cartilages and supporting cartilages along conducting passageways of the respiratory tract

Question 15

Elastic cartilage

Answer 15

extremely resilient and flexible because it contains numerous elastic fibers, found in auricle, epiglottis, windpipe

Question 16

Fibrocartilage

Answer 16

extremely durable and tough dominated by densely interwoven collagen fibers, found in intervertebral discs. Fibrocartilage resists compression, absorbs shocks, prevents damaging bone to bone contact, limits movement

Question 17

Mucous membrane

Answer 17

line passageways and chambers that open to exterior including those in the digestive, respiratory, urinary, and reproductive tract

Question 18

Serous membrane

Answer 18

line sealed, internal cavities of the trunk, cavities that are not open to the exterior

Question 19

Cutaneous membrane

Answer 19

skin that covers the surface of your body, is thick, relatively waterproof, and usually dry

Question 20

Synovial membranes

Answer 20

lines joint cavity, filled with synovial fluid

Question 21

Skeletal muscle

Answer 21

generates heat, protects internal organs, moves or stabilizes the position of skeletons.

Question 22

Cardiac muscle

Answer 22

found in heart, circulates blood, maintains blood pressure

Question 23

Smooth muscle

Answer 23

found in walls of blood vessels and in digestive, respiratory, urinary, and reproductive organs, move food, urine, and reproductive tract secretions

Question 24

Neurons

Answer 24

nerve cells, functional cell of the nervous system

Question 25

Neuroglia

Answer 25

supporting cells of the nervous system, helps neuron do its job

Question 26

inflammation

Answer 26

the process that isolates the injured area while damaged cells tissue components,

Question 27

Abscess

Answer 27

an accumulation of pus in an enclosed tissue space

Question 28

Celiac disease

Answer 28

the immune system responds to gluten protein, immune system damage the villi of the small intestine making hard to absorb nutrients

Question 29

Rheumatoid arthritis

Answer 29

the immune system attacks synovial membrane lining joints, causing pain, stiffness, warmth, and swelling of the joints and inflammation throughout the body
