25
Function of fibrous cartilage
* prevents bone to bone contact | * limits movement of joints
26
3 fibers in connective tissue
* collagen * reticular * elastic
27
Ground substance
Fills spaces between cells
28
Loose connective tissue function
Fills spaces within the body
29
Dense regular connective tissue function
Firm attachment
30
Dense irregular connective tissue function
Prevents over expansion of organs
31
Elastic connective tissue function
Stabilize vertebrae, shock absorption
32
Reticular connective tissue function
Supports functional cells
33
3 types of loose connective tissue
* areolar * adipose * reticular
34
3 types of dense connective tissue
* dense regular * dense irregular * elastic
35
Connective tissue proper
Connective tissue with many types of cells and extra cellular fibers
36
Supporting connective tissue
Less diverse cell population and has a matrix with more densely packed fibers
37
Areolar tissue
•Least specialized •separates skin from muscle •mostly ground substance •
38
What cell is always present in connective tissue
Fibroblast
39
Fibroblast function
Secrets fibers to build extralegal at matrix
40
Mucous membrane line
Passages and chambers exposed to the outside world
41
Serous membrane lines
Sealed inter subdivisions of the ventral (front) body cavity
42
Synovial membrane lines
Joints and cavities
43
Location of hyaline cartilage
* between ribs and joints | * covers ends of bones at joints
44
Where is fibrous cartilage found?
Between vertebrae
45
Where is elastic cartilage found
* ears and nose | * between vertebrae
46
Process that occurs after injury
* inflammation | * regeneration
47
Mast cell function
Stimulate inflammation
48
Microphages function
Blood cell that engulfs small bacteria
49
Lymphocytes function
Produce antibodies
50
Mesenchymal
Connective tissue stem cells that produce fibroblasts and macrophages
51
Macrophage function
Eat pathogens and damaged cells
52
Fibrocyte function
Maintain fibers and connective tissue
53
Where would stratified squamous epithelia be found
The outer layer of skin
54
Where would simple cuboidal be found
The ducts of glands
55
Where would simple columnar be found
The digestive tract
56
Where would pseudo stratified be found
Air passages
57
Where would simple squamous be found
Lining of air sacs in the lungs
58
3 categories of connective tissues
* connective tissue proper * fluid connective tissue * supporting connective tissue
58
Two types of fluid connective tissue
Blood and lymph
58
Adipose tissue function
Provides padding, absorbs shock, insulates
59
Adipocyte
Fat cells that store energy
59
Function if elastic cartilage
Provides support and tolerates distortion
59
Mucous membrane function
Line passages that open to the outside world
59
Serous membrane function
Line sealed internal cavities
59
Synovial membrane function
Creates synovial fluid that reduces friction between joints
59
Smooth muscle appearance, location, and control
* almond shaped, not striated, 1 nuclei in middle * surrounding hollow organs and blood vessels * involuntary
59
Cardiac muscle appearance, location, and control
* branched, striated, 1-2 nuclei * heart * involuntary
59
Skeletal muscle appearance, location, and control
* straight, many nuclei, striated * attached to tendon/bone * voluntary
