2. _Collagen Fiber___
3. _Elastic Fibers___
3-6: This slide shows a section of a tendon with regularly arranged closely packed collagen fibers running in the same direction. This results in a flexible tissue with great resistance to pulling forces. With its enormous tensile strength, this tissue forms cord like tendons, which join muscles to bones, sheet-like aponeuroses, which attach muscles to muscles or muscles to bones, and ligaments, which bind bones together at joints.
What classification of connective tissue is this? _Dense regular___
The nuclei of the cells that secrete the collagen fibers are indicated by the number 1. What type cells are these? _Collagen Fibers___
3-7: The cells of the connective tissue pictured below in a cross section from the trachea are specialized for fat storage and do not form ground substance or fibers. On prepared slides, this type tissue appears somewhat like a fish net with white spaces connected together in a network. The cytoplasm and nucleus have been pushed to one side by a single, large, fat-filled
