  • Connective tissue

    Connective tissue is the most diverse type of tissues – they are divided into connective tissues proper, resistive tissues (bone and cartilaginous tissues), blood and lymph.

    Characteristic of connective tissue is that fibres (collagen, resilient, reticuline fibres) are immersed in its basic substance. Of course, apart from the fibres there also are cells in the basic substance (of different kinds, depending on the tissue type).

    Fibres can be divided into three groups mentioned above, on account of their mechanical characteristics. Collagen fibres are the hardest, resistant to injuries, so they are part of tendons, bone and cartilaginous tissues. You can associate it with the knee, it will be easier to remember the name.

    Resilient fibres (called elastic), are less resistant to injuries, but they can be stretched. They can be found in blood vessel walls and resilient cartilaginous tissue.

    Reticuline fibres – most delicate; they can be found in lymph nodes (so in connective reticular tissue proper).

    Connective tissue proper – tissues of „inside environment”. They are divided into five different subtypes.

    Resistive connective tissue – they are bone tissue and cartilaginous tissue, they both have protective and support functions.

    Blood – the main type of liquid connective tissue, built of plasma and blood cells.
