Today in class there were several types of tissue on display under several different microscopes. The lesson taught the class the different types of tissues and how to identify them based off of their look and key features. For example, the lesson included a piece of cardiac tissue that included the disks in between the muscle as well as the branches the tissue makes. The lesson also helped us to look for distinct differences between the tissue types. Examples of the variations in tissues we looked at includes the fibrous strands found in muscle tissue and the difference in patterns between regular and irregular connective tissue. To further the classes understanding of the material, this lab challenged the class to identify where the tissue was located and how its anatomy affected its function. For example, the neuron cells located in nervous tissue are specialized with axons to relay messages to the next cell where the standard red blood cell uses fatty acids to communicate. The axon is specialized in the way that it conducts electrical impulses away from the cell body.
Another example of a type of tissue being specialized for its location and anatomy would be the muscular tissue. The muscular tissue is broken into three categories, each based off of location, anatomy, and function. One of the most fascinating, in my opinion, would be the cardiac tissue. The cardiac tissue's function is based off its anatomy and location as such. The cardiac tissue is only located in the heart, making it a very specialized tissue. The purpose of the tissue is to contract, pumping blood through the hearts vessels as it does. The anatomical component that allows the tissue to contract are the small disks that are intertwined within the tissue.
