ANATOMY/PHYSIOLOGY – HISTOLOGY LAB Tissues consist of the organized arrangement of cells together with intercellular substances produced by cells. Tissues are groups of cells having similar structural and functional characteristics. Tissues carry on one or more specialized functions for the body as a whole as well as meeting the requirements for their own survival. Tissues are made up of not only cells but the material between cells, interstitial fluid, as well. In this lab you will examine slides of various tissues in order to define the differences between tissues, their sizes, their shapes and their arrangements. PROCEDURE: For each of the 9 tissues below, you will be required to do four things: 1. 2. 3. 4. Draw a diagram of the tissues with labels. Draw a representation from a prepared slide of the tissue. Give the major function of the tissue (complete sentences). Give the location or locations of the tissue (complete sentences). TISSUES: 1. Ciliated Epithelium (AKA: pseudostratified epithelium) 2. Skeletal Muscle (AKA: striated muscle) 3. Hyaline Cartilage 4. Areolar Tissue (AKA: loose connective tissue) 5. Stratified Squamous Epithelium 6. Adipose Tissue 7. Giant Multipolar Neuron (AKA: nerve or neural tissue) 8. Tendon (AKA: dense connective tissue) 9. Simple Columnar Epithelium EXAMPLE: Use the example below as the format for each tissue. SIMPLE CUBOIDAL EPITHELIUM DIAGRAM PREPARED SLIDE Tissue Function: Simple cuboidal epithelial cells are equal in height and width. The cells are not actually cubed shaped. The name has been applied to them because of the way they appear through a cross section of the cell. Simple cuboidal cells consist of a single layer of cells, so they are capable of transporting materials. Tissue Location: Cuboidal epithelium is commonly found in the secretory portions of glands, or in the tubules of the kidneys and the tissue covering the ovary. Grading Guidelines: Each Tissue Labeled Diagram 3pts Colored Drawing 3pts Function 1pt Location 1pt 8pts X 9 Tissues = 72pts (1 page for each tissue) Cover page 3pts Total 72 + 3 = 75 points Grading Notes: There can be variations on this lab. For example if you don’t have prepared slide sets of all the tissues you can just have the students diagram the tissue with labels and eliminate the prepared slide drawing. The timing on my outline is based on the full project so your timing may be different. Another variation if you don’t have prepared slides is to add tissues to this list. This may also be done in a computer lab but will require several consecutive days. I have my students prepare the template on their own and then do the diagramming and drawing in class, I feel that having the students do the diagramming and drawing facilitates familiarity with the tissues instead of just downloading pictures from the internet. For my students if they don’t use a computer for the template the best grade they can get is a C.
