 Tissue Lab

          In this lab, we explored the four different types of tissues: muscle, nervous, epithelial, and connective. When looking at the different types of each of these tissues, we found that nervous tissue, pictured below, was a peripheral nerve and they transfer electrical signals from receptors. Each one of the tissue types are all different based on their locations and structures. For connective tissue it was either densely packed and parallel, like dense regular connective tissue, or were dense networks of fibers like dense irregular connective tissue. Epithelial tissue was layered and formed columnar and squamous shaped cells, as for the muscle tissue, the cardiac muscle tissue is found in the wall of the heart, uni-nucleate, and contracts to propel blood into the circulatory system. The smooth muscle, human, that was observed was consistent with what we had learned during class being that it was spindle-shaped and arranged closely to form sheets. As for the nervous tissue, pictured below, it was a peripheral nerve that has a cross section of nerve fibers. The nervous tissue is used to control and transmit electrical signals.
