| Except for what? connective tissue has a nerve supply | show 🗑
|
||||
| highly what? | show 🗑
|
||||
| show | may be fluid, semifluid, gelatinous, fibrous or solid. -- determines tissues qualities
🗑
|
||||
| show | divide
🗑
|
||||
| show | elastic
collagen
reticular
🗑
|
||||
| show | 1.binding, attachment and support (bones, tendons and ligaments, organs)
2.protections- bones and adipose tissue
3.insulation- adipose tissue
4.storage-of energy and fat soluble substances
5.transportation-food
🗑

| Loose Connective Tissue or Areolar Connective Tissue | show 🗑
|
||||
| show | cells are adipocytes, and specialized in storing fat. Adipocytes are tightly packer and very little matrix. -- accumulate under the skin and yellow marrow of long bones. Functions in energy reserves, insulation, protections and support.
🗑
|
||||
| Reticular Connective Tissue | show 🗑
|
||||
| show | collagen fibers are arranged in parallel bundles which makes this tissue flexible, but resistant to stretching. Fibroblasts are found in rows btwn the fibers. Found in tendons and ligaments. Blood supply is POOR!
🗑
|
||||
| Elastic Connective Tissue | show 🗑
|
||||
| Specialized Connective Tissues | show 🗑
|
||||
| show | -very fine collagen fibers and a resilient gel as its ground substance
-found in: embryonic skeleton, reduced frictions, absorbs shock, provides support.
-important in bone growth and repair
🗑
|
||||
| show | Has cartilage in a network of elastic fibers. It maintains the shape of organs such as the epiglottus of the larynx, auditory tubes, and external ears.
🗑
|
||||
| show | Contains visible bundles of collagen fibers and combines strengths and rigidity. Also acts as a shock absorber. It is found in th epubic symphysis, intervertebral discs, and menisci in joints
-STRONGEST CARTILAGE!
🗑
|
||||
| show | Collagen fibers (flexibility), mineral salts (hardness) and cells called osteocytes,
Basic unit: Oasteon or Haverslan system
-supports, protects, provide movements, store mineral, and house blood-forming tissue
🗑
|
||||
| show | consists of plasma and formed elements (cells)
-transport oxygen and carbon dioxide, carry on phagocytosis, participate in allergic reactions , provide immunity, and bring about blood clotting.
-erythrocytes, leukocytes, thrombocytes
🗑
