Q

Where is Adipose found?

A

Found under skin, around kidneys, within abdomen, and in breasts

22
Q

What fibers are found in Adipose?

A

Collagen fibers

23
Q

What is Reticular?

A

Loose ground substance with reticular fibers; reticualr cell lie in a fiber network

24
Q

Where can Reticular be found?

A

Found in lymph nodes, bone marrow, and the spleen

25
Q

What are the two types of Dense connective tissue proper?

A

Dense Regular and Dense Irregular

26
Q

What is Dense Regular?

A

Parallel collagen fibers with a few elastic fibers (wave)

27
Q

What is the cell type found in Dense Regular?

A

Fibroblasts

28
Q

What is the function of Dense Regualr?

A

Attaches muscles to bone or to other muscles, and bone to bone

29
Q

Where is the Dense Regular found?

A

Found in tendons, ligaments, and aponeuroses

30
Q

What is Dense Irregular?

A

Irregular arranged collagen fibers with some elastic fibers

31
Q

What is the Dense Irregular cell?

A

Fibroblasts

32
Q

What is the function of Dense Irregular

A

Withstands tensions in many directions probiding structural strength

33
Q

Where is Dense Irregular found?

A

Found in the dermis, submucosa of the digestive tract, and fibrous organ capsules

34
Q

What are the three types of cartilage?

A

Hyaline, Elastic, and Fibrocartilage

35
Q

What is Hyaline?

A

Firm matrix with imperceptible network of collagen fibers; chondrocytes lie in lacunae

36
Q

What is the function of Hyaline?

A

Supports, reinforces, cushions, and resists compression; forms the costal cartilage

37
Q

Where is Hyaline found?

A

Found in embryonic skeleton, the end of lone bones, nose, trachea, and larynx

38
Q

What is Elastic C?

A

Similar to hyaline cartilage but with more elastic fibers

39
Q

What is the function of Elastic C?

A

Maintains shape and structure while allowing flexibility

40
Q

Where would you find Elastic C?

A

Supports external ear (pinna) and the epiglottis

41
Q

What is fibrocartilage?

A

Matrix similar to hyaline but less firm with thick collagen fibers

42
Q

What is the function of fibrocartilage?

A

Provides tensile strength and absorbs compression shock

43
Q

Where is fibrocartilage found?

A

Found in intercertebral discs, the pubic symphysis, and in discs of the knee joint

44
Q

What is bone called?

A

Osseous Tissue

45
Q

What is bone?

A

Hard, calcified matrix with collagen fibers found in bone

46
Q

Where can bone be found?

A

Osteocytes are found in lacunae and are well vascularized

47
Q

What is bones function?

A

Supports, protects, and provides levers for muscular action; stores calcium, minerals, and fats

48
Q

What is blood called?

A

Hematopoietic

49
Q

What is blood?

A

Red and white cells in a fluid matrix (plasma)

50
Q

What is the function of blood?

A

The transport of respiratory gases, nutrients and wastes

51
Q

What are red blood cells called?

A

Erythrocyte

52
Q
