There are four types of tissues: epithelial, connective, muscular, and nervous, all that have their own function and are each unique and essential to the body. Being able to physically view the different types of tissues and their different types was helpful in better understanding the characteristics of the tissues and was really interesting. Epithelial tissue was either stratified or simple and although there are only three types- squamous, cuboidal, and columnar- each one was distinctly different. For example, in 400x magnification, the cilated columnar depicted a few columnar cells protruding from its base layer of cuboidal cells. Muscle cells were 'neater' since some showed parallel fibers with intercalated discs. There are three types of muscle tissue in the body: skeletal, smooth, and cardiac. Looking at the connective tissue, I could see the extracellular matrix and the specific cells. The dense collagenous bone was mostly parallel to allow for the high density of the tissue which makes it strong enough to be bone, and the collagen fibers were clearly seen. The nervous tissue was packed together with a large amount of cells that I could see through the microscope even at x400 magnification. However, I noticed the nerve fibers between the cells and the nuclei in each cell. The neurons are like this so they can easily and quickly transmit signals to different parts of the body. The tissues in our body all have a specific purpose to aid our body, whether we realize its purpose or not!
