20
Q

Simple cuboidal epithelium is a

A

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

21
Q

Stratified squamous epithelium consists of

A

several layers of closely packed cells.

22
Q

stratified squamous epithelial tissue protects

A

the body against invasion by microorganisms.

23
Q

Pseudostratified epithelium is

A

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

24
Q

Transitional Epithelium

A

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

25
Q

Connective tissue is found in

A

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

26
Q

Loose fibrous connective tissue

A

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

27
Q

Fibrous connective tissue,

A

composed of parallel bundles of collagen fibers,

28
Q

Adipose

A

white fat stores lipids

29
Q

(triglycerides

A

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

30
Q

Reticular tissue

A

delicate net of collagen fibers, as in bone marrow

31
Q

Dense fibrous tissue

A

bundles of strong collagen fibers, densely packed as in tendon

32
Q

Compact bone

A

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

33
Q

Cancellous bone

A

made up of thin, crisscrossing beams of bone

34
Q

Hyaline cartilage

A

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

35
Q

Fibrocartilage

A

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

36
Q

Elastic cartilage

A

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

37
Q

Blood tissue

A

matrix is fluid plasma;

38
Q

Hematopoietic tissue

A

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

39
Q

Muscle tissue types

A

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

40
Q

what are three kinds of muscle tissue

A

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

41
Q

Skeletal muscle tissue:

A

Attaches to bones; also called striated or voluntary;

42
Q

Cardiac muscle tissue

A

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

43
Q

Smooth muscle tissue

A

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

44
Q

Nervous tissue consists of two types of cells what are they

A

Nerve cells (neurons),Glia or neuroglia

45
Q

Nerve cells (neurons)

A

are the conducting units of the system

46
Q

Glia or neuroglia

A

these are special connecting and supporting cells

47
Q

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

A

One axon,One or more dendrites

48
Q

One or more dendrites

A

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

49
Q

One axon

A

axon transmits a nerve impulse away from the cell body.
