Body Tissues and the Integumentary System Your assignment is to answer the following questions. Describe the characteristics of epithelial tissue. (5 points) - Epithelial tissue covers surfaces like organs, lines cavities and forms glands. It lines the body surface. It is anchored to a basement membrane, made of tightly packed cells, lacks blood vessels, and contains minimal extracellular matrix material. The epithelial tissue is replaced frequently. The function of epithelial tissue is determined by the cell type and number of cell layers. There are two types of epithelial tissue: covering/lining epithelia and glandular epithelia. Functions of epithelial tissue are protection, secretion, absorption, excretion, and sensory reception. Describe the characteristics of connective tissue. (5 points) - Connective tissue is the most abundant tissue type in the body. It supports epithelial tissues. It forms tendons and ligaments, provides coverings that support and protect muscle and nervous tissue. The hardest connective tissue, bone, protects organs and provides a framework for movement of muscle. Adipose tissue insulates body and stores lipids. Connective tissue is not very cellular. Its extracellular matrix consists of fibers and ground substance that are made and secreted by different connective tissue. There are 3 different types of fiber that make up connective tissue: collagen fibers, elastin fibers, reticular fibers (produced by fibroblast). There are 5 types of mature connective tissue: loose connective tissue, dense connective tissue, cartilage, bone and bone Describe the characteristics of nervous tissue. (5 points) - Nervous tissue is the main component of the nervous system - the brain, spinal cord, and nerves-which regulates and controls body functions. It is composed of neurons, which transmit impulses, and the neuroglia cells, which
