Experiment 1 Tendons and Ligaments Connective tissue plays a key role in the muscular system securing muscles to bones tendons and holding bones in place ligaments Materials Tendon Muscle Insertion Digital Slide Image Tendon Digital Slide Image Tendon Longitudinal Section Digital Slide Image Ligament Longitudinal Section Digital Slide Image Ligament Digital Slide Image Post Lab Questions 1 Label the arrows in the slide images below based on your observations from the experiment A Chondrocytes B Collagen C Collagen Fibers D Skeletal Muscle Fibers E Nuclei F Collagen Fibers 2013 eScience Labs LLC All Rights Reserved 2013 eScience Labs LLC All Rights Reserved 2 How does the extra cellular matrix of connective tissues contribute to its function The extra cellular matrix consists of proteins and carbohydrates that binds cells together or divides one tissue from another It separates different tissue types The extracellular matrix is found in bones 3 Why are tendons and ligament tissues difficult to heal They do not have a significant blood supply which is needed to bring the nutrients that are needed for healing 4 What difference do you see between the tendon muscle insertion image 2013 eScience Labs LLC All Rights Reserved and the tendon image The tendon muscle insertion has dense irregular connective tissue and the directions are scattered The tendon muscle insertion consists of chondrocytes and collagen The tendon image consists of more than one nucleus it looks smoother and all moves in one direction 5 What differences do you see between the tendon and ligament sections The ligaments appear to be closer together while the tendon section appears to be more separated 2013 eScience Labs LLC All Rights Reserved
