29
what is the appearance of osseous tissue?
1) osteocytes held in lacunae surrounded 2) central canals at the center of collagen fiber wheels
30
what is lacunae?
cavities in connective tissue that hold cells in place
31

32
what is the most abundant cartilage?
hyaline
33
what is the appearance of hyaline cartilage?

34
what is characteristics and location of fibrocartilage?
1) highly compressable 2) wavey collagen fibers in matrix 3) located in between vertibrae of spinal column
35
what is the function and location of elastic cartilage?
1) provides elasticity 2) found in the outter ear
36
what is the appearance and location of dense connective tissue?
1) matrix contains numerous collagen fibers and the fibroblast cells that create them 2) located in tendons, ligaments, and dermis
37
what are tendons, ligaments, and dermis?
1) tendons-attach muscle to bone 2) ligaments- attach bone to bone 3) dermis- is the lower layers of the skin

39
what connective tissue can soak up fluid and cause adema?
areolar loose connective tissue
40
what is the appearance and function of areolar loose connective tissue?
1) matrix contains all fibers and has a cobweb like appearance 2) used to hold organs in place
41
which connective tissue is known as the universal packing glue?
areolar loose connective tissue
42
what is lamina propria?
a layer of areolar connective tissue that underlies all membranes
43
what is the function of adipose connective tissue?
1) insulate body 2) protects some organs 3) stores fuel
44
where is adipose connective tissue located?
1) under skin 2) around kidneys 3) deposits in hips, breast, and belly
45
what is the function of reticular connective tisse?
forms internal framework (stroma) of organs

55
whats the locations of smooth (visceral) muscle?
hollow organs such as 1) stomach 2) uterus 3) blood vessels
56
what is the location and function of neuroglia?
1) located throughout the matrix between neurons 2) they insulate, protect, and support neurons
57
what are neuron processes?
the network of wires that connect neurons together
58
what are the 2 types of tissue repair?
1) regeneration 2) fibrosis
59
what is tissue regeneration?
destroyed tissue is replaced with the same type of cells that were destroyed
60
what is tissue fibrosis?
destroyed tissue is replaced with fibrous connective tissue
61
regeneration or fibrosis depends on what 2 factors?
1) severity of injury 2) type of tissue damaged
62
what are the stages of tissue repair?
1) inflamation sets in 2) granulation tissue forms 3) permanent repair
63
what happens in the first stage of tissue repair?
1) capillaries become permeable 2) clotting proteins migrate from bloodstream 3) clot walls off inuured area
64
what happens in the second stage of tissue repair?
1) new capillaries grow 2) phagocytes get rid of clot and fibroblasts 3) rebuilds collagen fibers
65
what happens in the third stage of tissue repair?
