65
What is C.T.?
Cells and intercellular matrix that attaches (connects) anchors, and/or protects other tissues
*Matrix plays important role

75
What is collagen fibers?
Made from collagen, tri-helical structure, well-organized fibers, resist tensile loads (very little stretch)
76
What is elastic fibers?
Made from elastin, ability to stretch, develop tension and return to original length
77
What is reticular fibers?
Made from collagen fibrils (small fibers), poorly organized fibers
78
Loose C.T. consists of:
1) Areolar
2) Adipose
3) Reticular
79
Dense C.T. consists of:
1) Regular
2) Irregular
3) Elastic
80
Loose C.T. are:
Most abundant C.T., mostly collagen, filler tissue, holds vessels and nerves, poorly organized, found in subcutaneous areas
81
Dense C.T. are:
Primarily collagen in various organized arrangements
82
Areolar:
Gel-like matrix that wraps and cushions organs.
| Found under epithelium, (lamina propria) and surrounding capillaries and organs.
83
Adipose:
Cells=adipose cells are able to store large amounts of fat. Very little intercellular space.
84
Reticular:
Found within bone marrow, spleen, and lymph nodes. Similar appearance to areolar.
85
Regular:
Named b/c of its ordered arrangement of collagen fibers. Dense regular C.T.s are ideal at resisting tensile loads in one or few directions.
Tendons, ligaments, aponeuroses.
86
Irregular:
Collagen fibers have less ordered arrangements.
Although not as strong as regular dense C.T., they can withstand loads in numerous directions.
Fibrous joint capsules, skin dermis, periosteum.
87
Elastic:
Primarily consisting of elastic fibers (formed from protein elastin), ground in walls of arteries, trachea, and ligamentum nuchae (extension of supraspinous ligament)
88
Organs are...
Group of at least 2 tissues working cooperatively to perform a specific function.
Heart (Cardiovascular system)
Stomach (Digestive system)
89
Organ systems...
Group of organs and tissues functioning cooperatively to perform specific functions.
12 organ systems
90
What is cartilage?
```
Cells = Chondrocytes

```
91
What are the 3 types of cartilage?
1) Hyaline
2) Fibrous
3) Elastic
92
What is hyaline?
Strongest cartilage, approx. 40% collagen & 60% gel, articular cartilage, embryonic precursor to bone, forms synchondroses
93
What is fibrous?
70% collagen, 10% elastin, 20% gel, forms fibrocartilage pages and sympheses
94
What is elastic?
Mostly elastin, not found in joints, epiglottis and outer ears
95
Blood is...
Cells = erythrocytes, leukocytes, thrombocytes
Platelets = cell remnants
Contains cells, an intercellular fluid matrix plasma, and fibers albumin. Not typical b/c it doesn't really connect or support other tissues
96
Bones is...
Cells = osteoblast, osteocytes, osteoclasts
| Composed of organic and inorganic materials
