Connective tissue types
Flashcards do conjunto (16)
- 1Cell types varyfibroblasts, macrophages, adipocytes, red and white blood cells, chondrocytes.
- 2Extra cellular matrixGround substance and protein fibres
- 3Protein fibrescollagen - non-elastic, strong, flexible
elastic - rubbery, elastin, fibrillin
Reticular - thin and branched collagen with other proteins - 41. EmbryonicMesenchyme – forms all other kinds of connective tissue
- 52. Mature loose areolar- semifluid ground substance
- all 3 fibres types loosely dispersed
- fibroblasts predominate they secrete fibres and ground substance of CT - 63. Mature loose adipose- Adapted to store triglycerides (fat)
- adipocytes predominate
- acts as shock absorber and insulator in subcutaneous tissue - 74. Mature loose reticular- interwoven reticular fibres associate with reticular cells
- forms the stroma (supporting framework) in reticular organs (lymph nodes, spleen, bone marrow) - 85. Dense regular- closely packed parallel collagen fibres
- found in areas where tension is exerted in a single direction along axis of fibres
E.g. tendons and ligaments - 96. Dense irregularthick and irregular collagen fibres
found where tension is exerted in many different planes
E.g. dermis of skin - 107. Elasticdcombines strength with elasticity
recoils easily
E.g. artery walls - 118. Hyaline cartilage- most widely distributed
- firm support with flexibility
- forms articular cartilage at ends of long bones
- embryonic skeleton
Weakest of 3 kinds of cartilage. - 129. Elastic cartilage- has many more elastin fibres than hyaline cartilage
- found where strength and flexibility are needed
E.g. external ear - 1310. Fibrocartilage- Parallel collagen fibres - chondrocytes ‘squeezed’ in between
- Strong and rigid.
- Strongest of 3 kinds of cartilage
- Found where strong support is needed e.g. intervertebral discs. - 1411. Bone- Numerous collagen fibres with matrix of inorganic calcium salts
- Supports and protects soft tissues
- Fat storage and synthesis of blood cells - 1512. Blood- Atypical CT (a liquid connective tissue)
- Red and white blood cells surrounded by fluid plasma matrix
‘fibres’ are soluble proteins – become apparent on clotting - 1613. Lymph- Extracellular fluid
- Travels in lymphatic vessels
- Important in immune response
