Connective Tissues
3.5--Connective Tissues
Term | Definition |
---|---|
CONNECTIVE TISSUE | BINDS TOGETHER, SUPPORTS, AND STRENGTHENES OTHER BODY TISSUES. PROTECTS AND INSULATES ORGANS. COMPARTMENTALIZES STRUCTURES. VASCULAR. ADIPOSE = ENERGY. IMMUNITY |
EXTRACELLULAR MATRIX | CONTAINS PROTEIN FIBERS + GROUND SUBSTANCE. MATERIAL IN ECM DETERMINE'S CONNECTIVE TISSUE QUALITY |
FIBROBLAST | FOUND IN LOOSE AND DENSE CONNECTIVE TISSUE; SECRETE ECM OF TISSUE |
CHONDROBLAST | FOUND IN CARTILAGE |
OSTEOBLASTS | FOUND IN BONE |
TYPES OF CONNECTIVE TISSUE CELLS | INCLUDE EITHER: FIBROBLASTS, MACROPHAGES, PLASMA CELLS, MAST CELLS, ADIPOCYTES, WHITE BLOOD CELLS |
COLLAGEN FIBERS | VERY STRONG AND RESIST PULLING FORCES (TENSION); NOT STIFF, ALLOW FLEXIBILITY |
ELASTIC FIBERS | SMALLER THAN COLLAGEN; FORM FIBROUS NETWORK |
RETICULAR FIBERS | FORM A BRANCHING NETWORK; SUPPORT AND STRENGTH (FOUND IN LOOSE CONNECTIVE TISSUE) |
LOOSE CONNECTIVE TISSUE | AREOLAR CONNECTIVE TISSUE; LOOSELY ARRANGED; MORE ECM. ALL TYPES OF FIBERS. ALL TYPES OF CELLS |
LCT--ADIPOSE TISSUE | FAT STORAGE |
LCT--RETICULAR CONNECTIVE TISSUES | FINE INTERLACING NETWORK OF RETICULAR FIBERRS (THINNER COLLAGEN) AND RETICULAR CELLS |
DENSE CONNECTIVE TISSUE | CONTAINS MORE FIBERS THAN LOOSE, THICKER AND MORE DENSELY PACKED. LESS CELLS THOUGH |
DENSE REGULAR CONNECTIVE TISSUE | COLLAGEN ARRANGED IN BUNDLES WITH FIBROBLASTS PRESENT BETWEEN BUNDLES |
DENSE IRREGULAR CONNECTIVE TISSUE | TIGHTLY PACKED, WOVEN MESH USUALLY IRREGULARLY ARRANGED |
ELASTIC CONNECTIVE TISSUE | PRIMARILY ELASTIC FIBERS |
CARTILAGE (ALSO BONE QUALITIES) | DENSE NETWORK OF COLLAGEN FIBERS AND ELASTIC FIBERS. MORE GEL-LIKE GROUND SUBST. MORE DURABLE; RESILIENCE. |
CHONDROCYTES | MATURE CELLS OF CHONDROBLASTS. OCCUR IN LACUNAE |
PERICHONDRIUM | COVERING OF DENSE IRREGULAR CONNECTIVE TISSUE AROUND CARTILAGE WHICH CONTAINS BLOOD VESSELS AND NERVES AND NEW CELLS |
