what are the 3 types of epithelial layers?

['There are three principal cell shapes associated with epithelial cells: squamous epithelium, cuboidal epithelium, and columnar epithelium.', 'There are three ways of describing the layering of epithelium: simple, stratified, and pseudostratified.']

Nonkeratinized stratified squamous epithelium is in the superficial layers of lining mucosa, such as in the labial mucosa, buccal mucosa, and alveolar mucosa, as well as in the mucosa lining the floor of the mouth, the ventral surface of the tongue, and the soft palate (see Figure 9-2).

The corneal layers include epithelium, Bowman's layer, stroma, Descemet's membrane, and endothelium [Fig. 2].

['Epicardium (outer layer) consists of epithelium + connective tissue.', 'Myocardium (middle layer) cardiac muscle layer.', 'Endocardium (inner layer) consists of endothelium + connective tissue.']

Epidermis, the epithelial layer of skin, is primarily protective. This layer, consisting of keratinized stratified squamous epithelium, is tough, relatively impermeable, and self-replacing. These functional qualities are conferred by the epidermis' principal cell type, the keratinocyte.

['The epidermis provides a protective waterproof barrier that also keeps pathogens at bay and regulates body temperature.', 'The main layers of the epidermis are: stratum corneum, stratum lucidium, stratum granulosm, stratum spinosum, stratum germinativum (also called stratum basale).']

During embryonic development, the germ layers become differentiated into four kinds of tissues. These are epithelial, connective, muscular, and nervous tissues (Figure 9-3).

Oral mucosa lines the inside of the mouth and consists of stratified squamous epithelium as well as the connective tissue underneath. ... These tissues are formed by four layers: the basal layer, the spinous layer, the granular layer and the most superficial keratinized layer.

A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.

There are three main layers of the skin. Epidermis is the top layer of the skin, the part of the skin you see. Subcutaneous fat is the bottom layer.

The key difference between simple and compound epithelium is that simple epithelium has a single layer of cells while compound epithelium has more than one cell layer. There are two main types of epithelial tissue based on the number of cell layers. ...

In humans, there are four basic types of tissue: epithelial, connective, muscular, and nervous tissue. There may be various sub-tissues within each of the primary tissues. Epithelial tissue covers the body surface and forms the lining for most internal cavities.

Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane.

All segments of the GI tract are divided into four layers: the mucosa (epithelium, lamina propria, and muscular mucosae), the submucosa, the muscularis propria (inner circular muscle layer, intermuscular space, and outer longitudinal muscle layer), and the serosa (Figure 1).

The epidermis is the epithelial tissue layer of skin. Hair follicles, sebaceous glands, and sweat glands are epithelial invaginations from the epidermis.
