It does not have fibers like Compare and contrast the construction of the bladder and ureter walls. lines every body surface and all body cavity; thus it forms both the external and internal lining of many organs, and it constitues the majority of glands. All types of connective tissues consist of immature cells called blast cells that retain their capacity for cell division and secretion of the extracellular matrix. These tissues lie below basement membrane, called lamina propia. How can you distinguish among the different types of epithelium? For example the alveoli of the lungs are lined with simple epithelium because carbon dioxide and oxygen need to diffuse from the alveoli into the bloodstream and vice versa. epethilial tissue- structure.

The blood cells, also called the formed elements, carried by plasma are the erythrocytes (red blood cells), leukocytes (white blood cells) and thrombocytes (platelets). These secretions have far-reaching effects because they are distributed throughout the body by the bloodstream. Connective tissue is vascular and thus are rich in blood vessels, except for cartilages and tendons. White adipose tissue distributes into visceral and parietal fats. Collagen fibers and reticular fibers both belong to the collagen family, of which there are over 20 different types. Both tissues play a role in maintaining homeostasis within the body. Muscle tissue is divided into three types based on location and function: skeletal, cardiac, and smooth.

However, the free surface of the cells lining the small intestine is covered with microvilli, which increases the surface area for absorption of nutrients from the small intestine. For instance which epithelial tissue is found in the lips. Both connective and epithelial tissues mainly have a structural function. Name and classify 10 types of connective tissue, describe their cellular components and matrix, and explain what distinguishes them from each other. The ground substance is made up of glycosaminoglycans(GAG), proteoglycan and adhesive glycoproteins. Cells of the connective tissue are developed form the mesodermal embryonic germ layer. How are they different? There are three types of protein fibers; collagen, elastic and reticular. The ECM is vast, rich in water bound to glycosaminoglycans. Muscle and nervous tissues are considered excitable tissues. brain and the spinal cord and other types of tissues. what is producing the matrix. This cookie is set by GDPR Cookie Consent plugin. As all connective tissue, it has cellular and extracellular components. The fibers are collagenous, reticular and elactic.

The large structure with a central nucleus is the cell body of the neuron. Epithelial tissue is capable of continuous repair and renewal as they have a high rate of cell division where dead or injured cells are sloughed off and replaced by new ones. The cells are connected by elastin and collagen fibers along with blood vessels. A few epithelial layers are constructed from cells that are said to have a transitional shape. 1. What are some examples These tissues combine to form organslike the skin or kidneythat have specific, specialized functions within the body. Epithelial tissue acts as a protective barrier against foreign invaders. Both these components preform specific functions in the body, which helps to carryout basic forms of life. Epithelial tissue forms the covering of various organs and thus is the outermost tissue in most organs. In nervous tissue, the electrical impulse can travel long distances and is used as a form of communication. Epithelial tissue is found in various organs like skin, buccal cavity, the lining of blood vessels, body cavities, glands, and their ducts. Learn the structure and function of loose connective tissue here: or you're feeling ready for a test already?

Anatomy and Physiology. Adipose tissue, present underneath the skin acts as a heat insulator and also helps in connecting the skin to the tissue underneath. epithelial appearance varies, depending on whether the tissue is stretched or relaxed; shape of cells at apical surface changes; some cells may be binucleated. These are all examples of different types of connective tissue and many of them provide These two tissue types have the common function of protection from foreign bodies and toxins, as well as mechanical damage. Bounded by special proteins, desmosomes and hemidesmosomes are epithelial tissues; connective tissues are bounded by blood capillaries and materials like elastin or collagen fibers. The connective tissue is composed of different cells and a larger amount of extracellular matrix. Reticular tissue supports the stroma of body organs, especially lymphoid.
