|
|
Term
|
Definition
| Serves to bind or support organs; most widely distributed tissue in the body |
|
|
Term

|
Definition
1. Widely scattered cells in an extracellular matrix
2. presence of extracellular fibers
3. Vascular- Presence of capillaries |

Definition
adipose
loose/areolar
elastic
dense
bone
blood
cartilage |
|
|
Term
|
Definition
| Cells found in the areolar/loose connective tissue; Secretes a matrix that varies from being a liquid to a semisolid get |
|
|
Term
| Areolar/ loose connective tissue |
|
Definition
| found in the deeper layer of the skin and makes up the walls of blood vessels |
|
|
Term
| Adipose connective tissue |
|
Definition
| consists of fibroblasts that help in the storage of fat. The Fibroblasts have a large vacuole which stores fat. GIVES THE APPEARANCE OF A SIGNET RING |
|
|
Term
| Elastic Connective Tissue |
|
Definition
| Consists of more elastic (yellow) fibers which permit stretching; Found in the walls of arteries, the trachea, and vocal chords |
|
|
Term
|
Definition
| Categorized as irregular or regular. irregular= similar to areolar connective tissue, but contains fewer cells and more collagenous fibers. Regular (white)=has tightly packed parallel bundles of collagenous fibers; found in tendons, ligaments, and fascia |
|
|
Term
|
Definition
| Firm Matrix produced abd secreted by osteoblasts. Consists of: osteoblasts, lamella, cantral haversian canal, osteocytes, canaliculi, and osteoclasts |
|
|
Term
|
Definition
| bone-forming cells; produces bone matrix; housed on concentric rings (lamella) around the central haversian canal |
|
|
Term
| What runs through the Central (Haversian)canal |
|
Definition
| Blood Vessels, nerves, and lymphatic vessels |
|
|
Term
|
Definition
| trapped bone cells; located in lacunae similar to those found in cartilage |
|
|
Term
|
Definition
| A series of tiny channels that connect to lamallae |
|
|
Term
|
Definition
|
|
Term
|
Definition
| form of loose connective tissue; The matrix of blood is a liquid called plasma |
|
|
Term
|
Definition
| Specialized fibrous connective tissue; Within the matrix are numerous lacunea (depressions)that house cartilage producing cells called chondroblasts |
