Study unit 5 71 Answer the following questions. 1. Distinguish between slow and fast muscle fibres on the grounds of the structure, occurrence, innervation, irritability, response, physiological activities and functions. 2. Briefly distinguish between the three types of muscle tissue in terms of function and place of occurrence. 3. Distinguish between the structural and functional nature of muscles. 4. The primary functions of connective tissue is to connect and support body parts. What structural characteristics must this type of tissue have to perform this function successfully? Control your answers using the listed sources. Report any problems that you experience at the contact sessions. Practical/ Microscope work 10 1.

Study unit 5 72 5.4 NERVOUS TISSUE Sources Prescribed sources: Mader and Windelspecht pp. 593-594 Ross & Wilson pp. 139-140 Appendix 3 Introductory remarks Muscle fibres contract when they are stimulated by the neurons of the nervous system to contract. The nervous tissue is the last of the four groups of tissue discussed in this study unit. Nervous tissue is constructed from special cells, the neurons, which possess the ability to conduct nerve impulses as well as a special connective tissue, which appears as support tissue. This support tissue consists of cells that are commonly known as the neuroglia. (Neuro = nerve, glia = glue). Study hint: One of the best ways to study tissues is by means of a comparative study. Make use of a table.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
