24
Endocrine
Glands that have no duct and secrete hormones directly into blood
25
Exocrine
Glands that secrete by way if duct to body surface or body cavity
26
2 types of unicellular glands that secrete mucus
Mucus cells and goblet cells
27
Connective tissue is made up of
Extra cellular matrix
28
Three types of connective tissue
Collagen fibers Elastic fibers Reticular fibers
29
Collagen fibers
Give tensile strength (stretch)
30
Elastic fibers
allow stretch and recoil
31
Reticular fibers
Form supportive networks around blood vessels and other structures
32
Four main classes of connective tissue
Connective tissue proper Cartilage Bone Blood
33
2 kinda of connective tissue proper
Loose and dense connective tissue
34
Loose connective tissue
Areolar CT Adipose tissue Reticular CT
35
Areolar CT locations
Under epithelial, wraps organs
36
Adipose tissue locations
Under skin, around organs
37
Reticular CT locations

38
Areolar CT cell type
Fibroblast
39
Adipose tissue cell type
Adipocytes
40
Reticular CT cell type
Reticular cells
41
Dense connective tissue
Dense regular CT Dense irregular CT Elastic CT
42
Dense regular CT location
Tendon, ligament
43
Dense irregular CT location
Dermis, joint capsule
44
Elastic CT location
Aorta (walls of large arteries)
45
Dense regular CT cell type
Fibroblast
46
Dense irregular CT cell type
Fibroblast
47
Elastic CT cell type

59
Skeletal muscle nervous control
Voluntary
60
Cardiac muscle nervous control
Involuntary
61
Smooth muscle tissue locations
Wall of hollow organs, intestines, blood vessels
62
Smooth muscle tissue nervous control
Involuntary
63
Two types of nervous tissue
Neurons | Nuerolgicx
64
Neurons
Generate and conduct nerve impulses
65
Nuerolgic
Support, insulate, and protect neurons
66
3 membranes
Cutaneous membrane Mucous membrane Serous membrane
67
Cutaneous membrane
Largest membrane of the body, covers body surface, dry membrane
68
Mucous membrane
Line body cavities that are open to exterior; moist membranes
69
Serous membrane
Line body cavities that are closed to exterior and outer surface of some organs
70
Cutaneous membrane example
Skin
71
Mucous membrane example
Respiratory, digestive tracts
72
Serous membrane examples
Pericardium, pleura, peritoneumfunction
73
Cutaneous membrane function
Protects body
74
Mucous membrane function
Secrete lubricating mucus
75
Serous membrane function
Serous fluid to reduce friction
76
Parietal serosae
Lines internal body cavity walls
77
Visceral serosae
Covers internal organs
78
Tissue repair: regeneration
Replaced by original kind of tissue | Original function restored
79
Tissue repair: fibrosis
Replaced by connective tissue (scars) | Original function lost
