Question 16

how do you classify Epithelial Tissue as cell arragement

Answer 16

simple and Stratified

Question 17

Simple epithelial tissue

Answer 17

is a single layer of cells with the same shape.

Question 18

Stratified epithelial tissue

Answer 18

are many layers of cells.

Question 19

Simple squamous epithelium consists of

Answer 19

a single layer of very thin and irregularly shaped cells.

Question 20

Simple cuboidal epithelium is a

Answer 20

single layers of cells that are, on average, about as high as they are wide.

Question 21

Stratified squamous epithelium consists of

Answer 21

several layers of closely packed cells.

Question 22

stratified squamous epithelial tissue protects

Answer 22

the body against invasion by microorganisms.

Question 23

Pseudostratified epithelium is

Answer 23

made up of cells that reach the basement membrane and appear to be stratified because their nuclei are at different levels.

Question 24

Transitional Epithelium

Answer 24

lines the organs of the urinary system and is known here as urothelium.

Question 25

Connective tissue is found in

Answer 25

skin, membranes, muscles, bones, nerves, and all internal organs.

Question 26

Loose fibrous connective tissue

Answer 26

is not particularly tough, but surrounds blood vessels and provides support to internal organs

Question 27

Fibrous connective tissue,

Answer 27

composed of parallel bundles of collagen fibers,

Question 28

Adipose

Answer 28

white fat stores lipids

Question 29

(triglycerides

Answer 29

a type of fat (lipid) found in your blood.

Question 30

Reticular tissue

Answer 30

delicate net of collagen fibers, as in bone marrow

Question 31

Dense fibrous tissue

Answer 31

bundles of strong collagen fibers, densely packed as in tendon

Question 32

Compact bone

Answer 32

The solid form of bone that makes up the outer walls of bones in the skeleton

Question 33

Cancellous bone

Answer 33

made up of thin, crisscrossing beams of bone

Question 34

Hyaline cartilage

Answer 34

moderate amount of collagen in matrix; forms a flexible gel.

Question 35

Fibrocartilage

Answer 35

matrix is very dense with collagen; forms very tough, hard gel.

Question 36

Elastic cartilage

Answer 36

matrix has some collagen with elastin; forms a soft, elastic gel.

Question 37

Blood tissue

Answer 37

matrix is fluid plasma;

Question 38

Hematopoietic tissue

Answer 38

blood-forming tissue with a liquid matrix. This type of tissue is responsible for the formation of blood cells and lymphatic system cells important in our defense against disease

Question 39

Muscle tissue types

Answer 39

Muscle cells are the movement specialists of the body. They have a higher degree of contractility (ability to shorten or contract)

Question 40

what are three kinds of muscle tissue

Answer 40

skeletal muscle tissue ,cardiac muscle tissue, and smooth muscle tissue

Question 41

Skeletal muscle tissue:

Answer 41

Attaches to bones; also called striated or voluntary;

Question 42

Cardiac muscle tissue

Answer 42

Also called striated involuntary; composes heart wall, and the regular but involuntary contractions of cardiac muscle produce the heartbeat

Question 43

Smooth muscle tissue

Answer 43

Also called nonstriated (visceral) or involuntary; no cross striations; found in blood vessels and other tube-shaped organs

Question 44

Nervous tissue consists of two types of cells what are they

Answer 44

Nerve cells (neurons),Glia or neuroglia

Question 45

Nerve cells (neurons)

Answer 45

are the conducting units of the system

Question 46

Glia or neuroglia

Answer 46

these are special connecting and supporting cells

Question 47

All neurons are characterized by cell body and two types of processes:

Answer 47

One axon,One or more dendrites

Question 48

One or more dendrites

Answer 48

The dendrites carry impulses toward the cell body.Copyright © 2016 by Elsevier Inc. All rights reserve

Question 49

One axon

Answer 49

axon transmits a nerve impulse away from the cell body.
