Yes, sweat glands are made of modified epithelial tissue. They are formed by invaginations of the epidermis (outer layer of the skin) and consist of coiled tubular structures. These tubular structures are lined with specialized sweat gland epithelial cells that secrete sweat.
The cutaneous membrane is considered an epithelial membrane. It is composed of the outer epidermis (epithelial tissue) and the deeper dermis (connective tissue).

Epithelial cells cover the surface of the intestine.
Taste receptor cells are modified epithelial cells. These specialized cells are located within taste buds on the tongue and are responsible for detecting different tastes such as sweet, salty, sour, bitter, and umami.

It is because cells of epithelial tissues are found covering numerous internal and external surfaces of the body and may also be modified to form glandular structures.
A ciliated epithelial cell is modified with hair-like structures called cilia on its surface that help in moving substances along the cell surface. These cilia beat in a coordinated manner to generate a unidirectional flow of substances like mucus in the respiratory tract or egg in the fallopian tubes. The presence of cilia increases the surface area of the cell and enhances its function in moving materials efficiently.

Primary secretion of the liver is the raw secretion of substances by hepatocytes into the bile canaliculi. This kind of secretion has not yet been modified by the epithelial cells lining the bile ducts, which normally increase the amount of bicarbonate ions in the primary secretion as it passes by. A similar kind of primary secretion is that which is released by the end pieces of the salivary glands, which is later modified by epithelial cells lining the salivary ducts.
An epithelial membrane is a thin layer of tissue that covers organs, lines cavities, and forms the outer layer of the skin. It consists of epithelial cells attached to an underlying connective tissue layer. Epithelial membranes serve to protect, secrete, and absorb substances.
The cutaneous membrane is considered an epithelial membrane. It is composed of the outer epidermis (epithelial tissue) and the deeper dermis (connective tissue).
Epithelial tissue does not exhibit polarity.

Cerebrospinal fluid is produced by modified epithelial cells in the thin membrane that lines the ventricular system of the brain and the spinal cord. These modified epithelial cells are named the ependyma. Each of the cerebral ventricles has an associated choroid plexus (http://en.wikipedia.org/wiki/Ventricular_system) which produce and secrete cerebrospinal fluid. The cerebral ventricles are interconnected spaces within the brain that permit the fluid to circulate in a specific manner. (see http:/www.answers.com/topic/cerebrospinal-fluid?cat=health for an excellent diagram).
