Tissue Lab

This lab helped me learn about the different tissues and their structures. It was really interesting to see the different types of tissue under the microscope: epithelial, connective, muscular, and nervous tissue. After we looked at each tissue type, it's easier to understand their functions because form fits function and we could relate the tissues to the other types and look at their differences. This lab helped me understand the lecture notes more because in the lecture, we learned the different parts of the tissue and the functions. By observing the structure, its easier to understand how the tissue works in relation to the rest of the body. 

The differences between the different tissue types were obvious after looking at them through a microscope. For example, the connective tissue was tightly/ loosely backed with a bunch of tiny cells. Here is a picture of an epithelial cell from the microscope:

Here is a picture of the different types of connective tissue:

Here is a picture of the different nervous tissues:

Lastly, here is a picture I drew of the Human Skeletal Muscle (Muscle Tissue):

As you can see from the pictures, Epithelial Tissue looked like continuous sheets. The different shapes, such as simple squamous and stratified cuboidal, help account for the various functions of epithelial cells, like protection, absorption, secretion, and ion transport. The shape of the connective tissue was mainly tiny little fibers densely or loosely packed together. This shape helps fit the function of connective tissues, which is to bind together, support, and strengthen other body tissues. The shape of muscle tissues was either cylindrical (skeletal), branched (cardiac) or spindle shaped (smooth). The shape helps fit the function of each of the three muscle types.
