Reticular

Elastic

13

Which Connective Tissue Fiber is the most common and where is it found? How many directions can it resist force in?

Collagen

Found in tendons and Ligaments

One

14

Which connective tissue fiber is known for stabilizing functional cells and structures? How many directions can it resist force in and how does it interlock?

Reticular

Network of interwoven fibers (Stroma)

Strong and flexible

Resist force in MANY directions

15

Which Connective tissue contains Elastic and where is it found?

Elastic Fibers

Branched and wavy

Return to original length after stretching

Elastic ligaments of vertebrae and aorta

16

Which loose CT Proper is least specialized and where can it be found?

Areolar

Elastic Fibers (fibroblast cells)

Holds blood vessels and capillary beds

I.E. subcutaneous layer

17

What secretes the protiens that produce the college fibers?

fibroblast cells (large, flat, irregularly shaped)

18

What is the dense irregular connective tissue outside the cartilage called?

Perocondrium

19

What is the connective tissue layer surrounding the outside of the bone?

Periostium

20

What makes up most of the liver?

Reticular

21

What CT Proper Loose provides padding, cushion shocks, store energy, and insulates?

Adipose Tissue

22

What is the name of the cells that make up CT Proper, Loose Adipose Tissue?

Adipocytes

23

What do adipocytes store as energy?

Tryglicerides

24

What shape are elastic fibers?

Wavey

25

Name Reticular Tissue organs

Liver

Spleen

Lymph nodes

Bone marrow

26

What are the formed elements of blood?

Platelets

RBC (most numerous)

WBC

27

Which CT makes up tendons, ligaments, and aponeuroses?

Dense Regular CT

28

What is the function of Dense Regular CT?

Provide firm attachment

Conducts pull of muscle

reduce friction

29

What is Aponeuroses?

Large sheets that attach to large flat muscles like abdominal muscles

30

Which CT Proper is made up of interwoven networks of collagen?

Dense Irregular CT

31

Where can you find Dense Irregular CT?

In skin

Around Cartilage and Bones

in Capsules around some organs like liver and Kidneys

32

What CT helps to prevent over extension in the urinary bladder?

Dense Irregular CT

33

Where is Elastic CT found and what is it made with?

Found in arteries, elastic ligaments of spinal vertebrea

Made with Elastin

34

Name the two main types of Fluid Connective Tissues

Blood and Lymph

35

What are the two kinds supporting Connective Tissue?

Cartilage ( for shock support)

Bone ( for weight support)

36

What are the three types of Cartilage?

Hyaline

Elastic

Fibrocartilage

37

What is the major cells of Cartilage?

Chondrocytes (cartilage cells) surrounded by lacuna (chambers).

38

What is the major difference between Elastic Cartalage and Elastic tissue?

Elastic cartatalage has chondrocytes.

39

What cartilage is found in synovial joints, rib tips, sternum, and trachea?

Hyaline

40

What cartilage reduces friction between bones, gives stiff, flexible support and has no visible collagen or elastic fibers?

Hyaline

41

Which cartilage is found in the external ear and epiglottis? Why are they good for those areas?

Elastic cartilage

Its supportive but bends easily

42

This cartilage limits movement, provides padding in the knee joint, and prevents bone to bone contact?

Fibrocartilage

43

Where are the three big areas that fibrocartilage is found?

Knee joint

Pubic bone

intervertebral discs

44

What is the tissue name for bone?

Osseous Tissue

45

What is a bone cell called?

Osteocyte

46

How are Osteocytes arranged in a bone?

Around central canals within a matrix

47

There are small channels through the bone matrix. What are they called and what are they for?

Canaliculi

To access blood supply

48

Name the three kinds of Muscle Tissue

Skeletal

Cardiac

Smooth

49

What is skeletal muscle responsible for?

Movement

50

Where do you find cardiac and smooth muscle tissue at?

Cardiac - in heart

Smooth - in the walls of hollow contracting organs (I.E. Respiratory or G.I. tract)
