Q

What are the subtypes of bone tissue

A

Compact and spongy

21
Q

What types of cells are found in bone tissue

A

Osteocytes and osteoblasts

22
Q

What types of fibers are found in bone tissue

A

Collagen

23
Q

What is the function of bone tissue

A

Offering support and resisting compression and tension

24
Q

What types of cells are found in blood

A

Erythrocytes (red blood cells), leukocytes (white blood cells), and platelets

25
Q

What types of fibers are found in blood

A

None

26
Q

What is the function of blood

A

To carry oxygen, carbon dioxide, nutrients, wastes, and other substances (e.g. hormones)

27
Q

What are the subtypes of loose connective tissue

A

Areolar, adipose, and reticular

28
Q

What are the subclasses of dense connective tissue

A

Regular, irregular, and elastic

29
Q

What are the 7 cellular components of areolar connective tissue

A

Mast cells, macrophages, neutrophils, plasma cells, fat cells (adipocytes), lymphocytes, and fibroblasts

30
Q

What is the function of areolar connective tissue

A

Supporting epithelial tissues and offering a barrier to pathogens

31
Q

What are the 3 characteristics and functions of adipose tissue

A

Good for protection and nutrient storage, has a high concentration of fats cells full of lipids, found in the hypodermis

32
Q

What are the characteristics of reticular connective tissue

A

It’s a network of reticular fibers found in organs like spleen where there is a high concentration of blood cells

33
Q

What are the characteristics of dense regular CT?

A

Collagen fibers run parallel to one another (e.g. in ligaments and tendons) when you can predict where the force is coming from

34
Q

What causes hyper extension?

A

Longer ligaments

35
Q

What are the characteristics of dense irregular CT?

A

Collagen fibers running in many directions (e.g. in joint capsule and muscle fascia)

36
Q

What are the characteristics of elastic CT

A

Lots of elastic fibers so common in organs stretching and quickly going back to their original shape (e.g. in large arteries helping heart relax and mediating high/low blood pressure)

37
Q

What happens in Fibrodysplasia Ossificans Progressiva (FOP)

A

Fibers are replaced by bone tissue

38
Q

What is a membrane

A

Epithelial tissue and CT proper

39
Q

What are the 3 kinds of membranes

A

Cutaneous, mucous, and serous

40
Q

What is the cutaneous membrane

A

And organ also known as the skin made up of the epidermis (epithelium) and the dermis (connective tissue)

41
Q

Where are mucous membranes

A

Lining organs that open to outside the body (e.g. in nasal cavity, mouth, esophagus, intestines, and lung bronchi)

42
Q

Where are serous membranes

A

Surrounding the outside of organs and lining body cavities to help anchor things (e.g. outer wall of stomach)

43
Q

In a mucous membrane, what part secretes the mucus coating

A

The epithelial cells

44
Q

What are the 2 layers of the serous membranes

A

Visceral layer surrounding organs and parietal layer lining the body cavity

45
Q

What is the function of serous membranes

A

Epithelial cells secrete lubrication fluid to prevent friction between organs

46
Q

Where are the 3 locations of serous membranes

A

Peritoneum, pleura, and pericardium

47
Q

Where is the peritoneum

A

Abdominopelvic cavity and surrounding abdominopelvic organs

48
Q

Where is the pleura

A

Pleural cavity surrounding lungs

49
Q

Where is the pericardium

A

Pericardial cavity surrounding heart
