However, the structural components of connective tissues are consistent. All connective tissue is derived from mesoderm, the middle germ cell layer in the embryo. Connective tissues perform many functions in the body, but most importantly, they support and connect other tissues; from the connective tissue sheath that surrounds muscle cells, to the tendons that attach muscles to bones, and to the skeleton that supports the positions of the body. The extracellular matrix is made up of a ground substance and protein fibers. This tissue has a spongy structure and stores water, glucose and salt. Tissues are groups of cells with a common structure (form) and function (job). A synovial membrane is a type of connective tissue membrane that lines the cavity of a freely movable joint. Along with epithelial tissue, muscle tissue, and nervous tissue, connective tissue is one of the four essential forms of animal tissue. Connective tissue is found between other tissue types and organs. The lungs and arteries have a layer of elastic connective tissue that allows the stretch and recoil of these organs. connective tissue. Connective tissue is classified into two subtypes which are soft and specialized connective tissue. Location. This type of tissue is the most abundant, widespread, and varied of all tissue types in the body. Connective tissue can further be broken down into three categories: loose connective tissue, dense connective tissue, and specialized connective tissue. Peter Takizawa.

This offers great diversity in the types of connective tissue. Knowledge of the development of the connective tissues is important, for the stages of repair in wound healing have considerable similarity to embryonic developmental stages. A few distinct cell types and densely packed fibers in a matrix characterize these tissues. Unlike other connective tissues, its extracellular components are mineralized giving it substantial strength and rigidity. Structure. Areolar connective tissue is made of cells and extracellular matrix ("extra-" means "outside", so the extracellular matrix is material that is outside of the cells). A whole skeletal muscle is considered an organ of the muscular system.Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue.. Skeletal muscles vary considerably in size, shape, and arrangement of fibers. In the images on this page, you can see the fibers very easily-they look like threads. Muscular tissue. Connective tissue can bind & support, protect, insulate, store reserve fuel, and transport substances within . mast cell. Today's Rank--0. The fibers can be arranged irregularly or regularly with the strands lined up in parallel. Reticular connective tissues are arranged along with different cells in various organs like bone marrow, lymph nodes, spleen, liver, kidneys, and even under the skin. Organs, such as the small intestine, are structurally weaker than tendon because they require connective tissue to provide metabolic and immune support so the connective tissue must contain blood vessels, macrophages, lymphocytes. A whole skeletal muscle is considered an organ of the muscular system.Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue.. Skeletal muscles vary considerably in size, shape, and arrangement of fibers.
