Tissue Lab

In this lab, we observed twelve different kinds of tissue slides.  We got to look at slides through a microscope and figure out what kind of tissue it was and what type of cells they were. There were two connective, three epithelial, six muscle tissue, and one nervous tissue. During the lab I noticed that the bone cells look a lot different then all of the other cells, which are bundles of fibers which are held together by loose connective tissue. I also noticed that the connective tissue had a lot of individual cells spread out, rather than tightly layered together.  Mr. Orre taught us about the tissues and their functions, connective tissue fills spaces between organs and tissues, provides structural and metabolic support for other tissues and organs. Epithelial tissue covers a body surface or lines a body cavity. Muscle tissue helps with movement and is composed on actin and myosin fibers.  Nervous tissue transmits electrical signals from sensory receptors to effectors, it is found in the brain, spinal cord and nerves.
