Types of Epithelial Tissue
Types of epithelial tissue
Connective tissue -Connective tissues are fibrous tissues. They are comprised of cells separated by non-living material, which is called extracellular matrix. Connective tissue holds other tissues together such as in the formation of organs, and has the ability to stretch and contract passively. Bone, often referred to as osseous tissue, and blood are examples of specialized connective tissues. Conective tissues are cells that are suspended in a matrix of their own secretions.
Muscle tissue -Muscle cells form the active contractile tissue of the body known as muscle tissue. Muscle tissue functions to produce force and cause motion, either locomotion or movement within internal organs. Muscle tissue is separated into three distinct categories: visceral or smooth muscle, which is found in the inner linings of organs; skeletal muscle, in which is found attached to bone providing for gross movement; and cardiac muscle which is found in the heart, allowing it to contract and pump blood throughout an organism.
Nervous tissue- Cells comprising the central nervous system and peripheral nervous system are classified as neural tissue. In the central nervous system, neural tissue forms the brain, cranial nerves and spinal cord and, in the peripheral nervous system forms the peripheral nerves, inclusive of the motor neurons.
Epithelial tissue- The epithelial tissues are formed by layers of cells that cover organ surfaces such as the surface of the skin, the airways, the reproductive tract, and the inner lining of the digestive tract. The cells comprising an epithelial layer are linked via semi-permeable, tight junctions; hence, this tissue provides a barrier between the external environment and the organism it covers. In addition to this protective function, epithelial tissue may also be specialized to function in secretion and absorption.
Squamous and cuboidal tissue - The simple squamous tissue looks like a geometric pattern when viewed from

    Epithelial tissues are the inside layer of internal and external surfaces and body cavities, including ducts carrying secretions from glands. They may be composed of some layers of cells, called compound epithelia or just a single layer which is known as simple epithelia. The lowest or bottom layer of cells is attached to the basement membrane for support and connection. Part of the basement membrane is concealed by the epithelia but they are supplied with oxygen and nutrients from deeper tissues by diffusion which is the passage of the molecules from a high concentration to a low concentration. As they are surface tissues and exposed to friction, their ability for growth and repair is greater than other tissues and generally occurs during sleep.…

    Due to its anatomical structure, this thin and permeable epithelium is found in areas of the body where protection is not important and where there is a high demand for filtration or exchange of substances by rapid diffusion. Along with rapid diffusion, simple squamous epithelium secretes lubricating substances in serosae which keeps the surface smooth and reduces the overall amount of surface friction. This highly permeable epithelium can be found in the kidney glomeruli; lining of heart, blood vessels, and lymphatic vessels; lining of the ventral body cavity (serosae) and the air sacs of the lungs. In Room 28’s case, simple squamous epithelium forms the walls of the alveoli where gas exchange occurs (Hoehn &Marieb, 2010b).…

    There are four different types of tissue. They are; nerve, epithelial, connective, and muscle. The nerve tissue is made up of neurons that receive and transmit electrical impulses, this is their function. There are several different types of epithelial tissue. First there is simple squamous epithelium tissue. This is a single layer of cells that is in the lining of blood vessels, the lining of the pulmonary alveoli, and the Bowman’s capsule in the kidneys. The function of this tissue is to separate blood from the fluid in tissues and to separate air from fluids in tissues and to filter substances from blood to form urine. The next type of epithelial tissue is stratified squamous epithelium. This is a tissue composed of two or more layers and the cells tend to be cuboidal. This type of tissue is found in the epidermis of the skin and the linings of the mouth, pharynx, esophagus and anus. The function of this tissue is to protect and secrete. Transitional epithelium is the next type of tissue and it varies in shape from cuboidal to squamous. It is located in the linings of the urinary bladder and other hollow structures. Its function is to allow stretching to expand the organ that it is in. The next type is simple cuboidal epithelium. It is cuboidal cells that are in glands and parts of the kidney tubule and outer covering of ovaries. The function of this tissue type is secretion. Simple columnar epithelium is next and it is in the lining of the digestive tract and in ducts of many glands. Its function is to secrete and absorb from the stomach to the anus. Ciliated simple columnar epithelium is in the linings of the bronchi of the lungs, nasal cavity and oviducts. Its function is to secrete, absorb and propel fluids and particles. Then there is stratified columnar epithelium and it is in the linings of the epiglottis, pharynx, anus and male urethra. Its function is protection.…
