Connective Tissue Flashcards
Three basic components of connective tissue
Cells, protein fibers, and ground substance
Connective tissue cell types
Fat – adipocytes
Cartilage - chondrocytes
Bone – osteocytes
Three protein fibers of connective tissue
Collagen, fibers – stretch resistant, unbranched
Elastic fibers – flexible, branched
Reticular, fiber, – interwoven, flexible, branched
Connective, tissue, ground substance
Nonliving material produced by the connected tissue cells. Maybe viscous, semi solid, or solid. The extracellular matrix is formed by protein fiber
Connective, tissues function
Physical protection
Support and structural framework
Binding of structures
Storage, transport, immune protection
Connective tissue classification
Fluid connective tissue
Connective tissue proper
Supporting connective tissue
Blood connective, tissue structure
Erythrocytes, leukocytes, and platelets
Blood connected tissue function
Erythrocytes, transport, gas
Leukocytes mount and adaptive immune response
Platelets involved with blood clotting
Plasma transports nutrients, waste and hormones
Blood connective tissue location
Primarily found within the blood vessels, the heart and lymphatic organs
Connective tissue proper, 2 types
Loose connective tissue
Dense, connective tissue
Loose connective tissue characteristics
Fewer cells and fibers
Protein fiber are loosely, arranged
Acts as bodies packing material
Loose connective tissue subtypes
1 Areolar
2 Adipose
3 reticular
Dense, connective tissue characteristics
Primarily protein fibers, less ground substance
Collagen fiber dominant
Dense connective tissue, three sub types
1 dense, regular
2 dense, irregular
3 Elastic
Areolar connective, tissue structure
Organized, collagen and elastic fibers, abundant blood vessels
Fibroblast predominant cell
Ground substance is viscous and gel like
Areolar, connective tissue function
Surrounds and protects tissues in organs
Loosely binds epithelia to deeper tissue
Provide nerve and blood vessel, packing
Areolar connective, tissue location
Papillary layers of dermis
Subcutaneous layer
Surrounds nerves, blood vessels, individual muscle cells, and organs
Reticular, connective, tissue structure
Meshwork of reticular, fibers, fibroblasts, and leukocytes
Ground substance is gel like
Reticular connected tissue function
Provides a support framework for spleen, lymph nodes, thymus, and bone marrow
Reticular, connective, tissue location
Forms, stroma of lymph nodes, spleen, thymus, and bone marrow
Adipose connected tissue structure
Specialized for fat storage, does not form ground substance or fibers
Cytoplasm and nucleus push to one side Center is fat, filled vacuole
Adipose connective tissue function
Stores energy
, Cushions, and insulates
Adipose connective, tissue location
Subcutaneous layer
Surrounds some organs
Dense, regular connective, tissue structure
Tightly packed, collagen fibers
Aligned parallel to an applied force
Fibroblast nuclei between layers of fibers
Limited substance
Dense regular connected tissue function
Muscle to bone – tendons
Bone to bone – ligaments
Resist stress applied in One Direction
Dense, regular connective tissue location
Found in tendons and ligaments
Elastic connective, tissue structure
Branching, elastic, fibers, packed, collagen, fibers, higher count of fibroblasts
Elastic connective tissue function
Elastic fibers, provide resilience, the ability to deform and return to normal shape
Allows stretching of some organs
Elastic connective tissue location
Walls of large and medium arteries
Trachea
Bronchial tubes
True vocal cords
Suspensory ligaments of the penis
