2 PRE hyphen.uc LAB EXERCISES Open the A&P app, and from the left-side menu, select Cells and Tissue and then choose Chapter 4. Tissues. Use the modules to guide your exploration of the tissue types in the body. Be sure to use the book icon to learn more about the cellular concepts that you are exploring. You are responsible for the identification of all bold terms and all answers to the questions. A. Explore the 3D anatomical view in Module 4.1 Tissue Types in the Body and answer the following questions. Downloaded by Nathaniel SAINT-FORT (nathanielsaintfort@gmail.com) lOMoARcPSD|30471583

3 1. In the following table, list the four major types of body tissue and provide a general description of each type. Type of body tissue General description Epithelial Tissue Epithelial tissue is one of the most abundant body tissue, that primarily function to provide protection via making covering on the internal and skin body organs Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules. Connective Tissue The connective tissue are specific form of body tissue that primarily function to associate or connect the nearby structures and provide them strength in different ways Connective tissue underlies and supports other tissue types. Muscular Tissue These involve skeletal, smooth, and cardiac muscles that have basis function to provide specific motility or movement to different body structures via their unique contraction ability Muscle tissue contracts to initiate movement in the body. Nervous Tissue Nervous tissue is most unique in its structure and function, because they composed of longest cells in the body and primarily function to carry or convey the sensory and motor information among the body organs. The brain and spinal cord are two major parts of the nervous system and have the function to control and coordination in the body. Nervous tissue transmits and integrates information through the central and peripheral nervous systems. Downloaded by Nathaniel SAINT-FORT (nathanielsaintfort@gmail.com) lOMoARcPSD|30471583

4 2. What are two types of specialized connective tissue that consist of cells in a fluid matrix (not a ground substance with fibers)? ______________________________ ______________________________ B. Explore the 3D anatomical views in Modules 4.2 Epithelial Tissue, 4.6 Connective Tissue, 4.17 Muscle Tissue, and 4.19 Nervous Tissue. Use these modules to answer the following questions about the structure and functions of the four major types of body tissues. Skin Glands Internal tracts Blood fluid connective tissue Lymph fluid connective tissue Downloaded by Nathaniel SAINT-FORT (nathanielsaintfort@gmail.com) lOMoARcPSD|30471583

5 2. Next, explore Module 4.6 Connective Tissue to learn about the four types of connective tissue, which have wildly different material properties. In the following table, provide examples of the different types of connective tissue. 1. First, explore Module 4.2 Epithelial Tissue to learn about the two types of epithelial tissue : epithelial sheets (including skin) and glands. What observations can you make about the unique characteristics of epithelial sheets and glands? Cartilage Lymph Bone Blood Characteristics of sheet Epithelia: They appear as continuous sheet of cells that cover the surface of the body. Epithelial sheets are attached to basement membrane that acts as sites of attachment and as a selective barrier. These cells also tend to show polarity and do not possess their own blood supply so termed as avascular. Sheets rely on diffusion for exchange of nutrients like O2 and metabolites. They communicate via cell-cell junctions called gap junctions that allow cells to communicate with adjacent cells. Epithelial Glands appear as collection of organised secretory epithelial cells formed during development by proliferation of epithelial cells underlying the connective tissue. These organs retain their communication via a duct sytem and are celled exocrine glands while those that lose this direct duct system are known as endocrine glands. These glands secrete various macromolecules like hormones. Downloaded by Nathaniel SAINT-FORT (nathanielsaintfort@gmail.com) lOMoARcPSD|30471583
