27
Q

Avascular is quick to heal when damaged T | F

A

False

28
Q

What is the most unusual type of CT?

A

Blood–the matrix is fluid

29
Q

What is the function of blood CT?

A

transportation, body temp, pH, immunity.

30
Q

What is hematopoietic tissue?

A

Blood like connective tissue found in red marrow cavities. . Forms blood and lymphatic cells. Important in immunity. Called spongy bone because of appearance.

31
Q

Examples of hematopoietic tissue:

A

Blood, spleen, tonsils, and lymph nodes.

32
Q

What is muscle tissue?

A

Have the highest degree of contractability.

33
Q

Are muscle tissues quick or slow to heal?

A

Slow–scare form at sight of injury.

34
Q

What are the three types of muscle?

A

Skeletal, cardiac, and smooth.

35
Q

Skeletal Muscle:

A

Attaches to bones (via tendons).

36
Q

Control is _______ with skeletal muscle. (voluntary or involuntary)

A

Voluntary

37
Q

Ligament is _____ to ______

A

Bone to bone

38
Q

Tendon is _______ to _______

A

Muscle to bone

39
Q

Cardiac Muscle

A

Forms the walls of the heart. Produces regular, involuntary contractions of cardiac muscle for heartbeat. Has faint cross striation and thicker dark band called intercalated disks.

40
Q

Smooth Muscle

A

Has involuntary control. Appears smooth–without cross striations. Forms walls of blood vessels, hollow organs eg. intestines.

41
Q

Neurons can’t be repaired. T | F

A

True

42
Q

What are the 2 types of epithelial tissue?

A

Membraneous and glandular.

43
Q

What is membraneous epithelium?

A

Covers the body and some of it’s parts; lines the serous cavities, blood, and lymphatic vessels, and respiratory, digestive, and genitourinary tracts.

44
Q

What is the glandular epithelium?

A

Secretory units of endocrine and exocrine glands.

45
Q

What are functions of epithelial tissue?

A 
Protection
Sensory functions
Secretion
Absorption
Excretion
46
Q

Epithelial tissue is _________.

A

Avascular

47
Q

What are the 4 classifications of epithelial tissue (by shape)?

A

Squamous
Cubodial
Columnar
Pseudostratified Columnar

48
Q

What are the 4 classifications of epithelial tissue (by layers/arrangement of cells)?

A

Simple (single layer)
Stratified (multiple layers)
Transitional (shapes that can stretch)

49
Q 
True or False
Types of epithelial tissues:
Simple squamous 
Stratified squamous
Simple columnar 
Stratified transitional
Pseudostratified
A

True

50
Q

Simple Squamous:

A

Single layer of flat “scale” shaped cells. Structure is perfect for diffusion and is permeable to many substances.

51
Q

Where is simple squamous tissue located in the body?

A

Alveoli of lungs, lining of blood & lymphatic vessels

52
Q

Simple Cubodial:

A

Single layer of cube-shaped cells and are specialized in secretory activity (saliva, digestive juices, sweat, hormones).

53
Q

Simple cubodials are grouped into tubules and glands T | F

A

True

Tubules- urine producing tubules of kidneys.
Glands-With or without ducts.

54
Q

How does pseudostratified epithelium differ from stratified epithelium?

A

Each cell touches basement membrane.

55
Q

Simple Columnar:

A

Single layer of tall, narrow, column-shaped cells. Composes the surface of mucous membranes that line the stomach, intestines, parts of respiratory & reproductive systems. For absorption.

56
Q

What is the special function of simple columnar epithelium

A

Mucus production

57
Q

Pseudostratified Columnar:

A

Columnar cells of varying heights and they line the respiratory tract and reproductive system. It is a single layer that appears as if there is two or more layers.

58
Q

Stratified Squamous:

A

Several layers of closely packed cells and protection is its primary function. Can be keratinized and non-keratinized.

59
Q

Stratified Cubodial:

A

Two or more rows of cubodial cells arranged over a basement membrane. Its function is protection and is located in sweat glands, pharynx, etc.

60
Q

Stratified Columnar:

A

Multiple layers of columnar cells, and only the most superficial cells are typical in shape. They are protective and rare (located in male urethra).

61
Q

Stratified Transitional:

A

Up to 10 layers of roughly cubodial shaped cells that distort to a squamous shape when stretched. It is protective and found in the bladder.

62
Q

What are the 2 types of epithelial tissues?

A

Membraneous and Glandular.

63
Q

What are membranous epithelium?

A

Covers the body and some of its parts; lines the serous cavities, blood & lympathic vessels, and respiratory, digestive, and genitourinary tracts.
