Connective tissue
Cards in this deck (19)
- 1Name 3 categories of connective tissueConnective tissue proper (loose and dense connective tissues, fluid connective tissue and supporting connective tissue
- 2Describe functions of connective tissueStorage (energy, adipose), Defence (immunity, inflammation), Repair (scarring, regeneration), Communication and transport (nutrients, gases, wastes, messenger molecules)
- 3Describe structureSpecialised cells, fibres, extracellular matrix (abundant intracellular material, amorphous ground material)
- 4Describe classification of connective tissueFibres < Cells = loose
Fibres > cells = dense - 5Describe arrangement classification of CTparallel = regular
non-parallel = irregular - 6Describe function and location of Dense Regular CTFunction - bonds bones together, attaches muscle to bone, transfers force from muscle to bone
Location - tondons & ligaments - 7Describe function and location of Dense Irregular CTFunction - Protects organs from injury, provides protective capsules around many organs
Location - dermis of skin, capsules around liver, spleen, and other organs - 8Describe function and location of Loose CTFunction - nourishes and cushions epithelia, provides arena for immune defence against infection, binds organs together, allows passage for nerves and blood vessels through other tissues
Location - Underlines all epithelia, outer coverings of blood vessels, nerves, oesophagus, and other organs, fascia between muscles, pleural and pericardial sacs - 9Describe extracellular matrixProvides support to surrounding cells and fibres, regulates intercellular communication, transports substances through CT, clear colourless viscous (fluid), consists of glycans (carbohydrates), protein and water,
- 10Name fibers in CTReticular, collagen and elastic
- 11Describe collagen fibersMain structural protein, most abundant, amount and arrangement vary according to tissue function, provide strength and cushioning, cartilage, bone, tendon, ligament
- 12Describe elastin fibreshighly elastic protein, allows for coil and recoil, diminishes as we age, provides flexibility and elasticity, skin, arteries, bronchi
- 13Describe reticular fibresstructural proteins, forms a delicate irregular, flexible framework, inelastic, support cellular structures, spleen, liver, marrow
- 14Describe fibroblastsmost common CT cells, produce all fibres and ECM in CT, respond to injury by dividing and producing large amounts of collagen, form scar tissue
- 15Describe Adipocytesstore fat as source of energy, insulation (hypodermic), shock absorbers (palms, soles), protective padding (kidneys)
- 16Describe macrophagesscavenger defence cells, act by phagocytosis of cell debris, bacteria, cancer cells, intercellular components
- 17Plasma CellProduces antibodies (immunoglobulins)
- 18LeukocyteW
- 19Mast cellstore chemical mediators of the inflammatory response
