Simple columnar epithelium [1]
Simple columnar epithelium consists of a single layer of cells that are taller than they are wide, with an oval nucleus usually located towards the basal region of the cell. As its name suggests, the cells of this epithelium have a column-like appearance in sections perpendicular to the basement membrane
The ciliated simple columnar epithelium bears cilia (finger-like projections of the plasma membrane) on the apical surfaces of cells, with goblet cells usually scattered throughout the epithelium. Up to 300 cilia may be present on each cell, beating in a synchronized manner with adjacent cells to propel materials over the surface of the epithelium
Nonciliated simple columnar epithelium, on the other hand, has no cilia but typically has microvilli, which are small cytoplasmic projections on the apical surface of cells. As well, there are goblet cells interspersed within the epithelium
Overview and types of epithelial tissue [2]
Epithelium is one of only 4 types of human body tissues. Like all types, it is formed by cells within an extracellular matrix (ECM).
Forming sheets that cover the internal and external body surfaces (surface epithelium) and secreting organs (glandular epithelium). Functions of epithelial tissue are secretion, protection, absorption, transportation and special sensory receptive.
|Cell shape classification||Squamous, cuboidal, columnar|. |Cell layer classification||Simple, stratified, pseudostratified, transitional|
In what kind of tissue can goblet cells be found? [3]
Hint: Simple epithelia, such as cuboidal, columnar, and pseudostratified epithelia, contain goblet cells, which are unicellular intraepithelial mucin-secreting glands. Their name comes from the fact that they have a goblet-like shape, with narrow bases and a large tip
Goblet cells are protective, yet they can also be harmful.. There are four types of basic tissues in the body: Epithelial, Connective, Muscle and Nervous tissue
Goblet cells are simple columnar cells with an epithelial morphology that release mucins that create gels, such as MUC5AC. The merocrine mechanism of secretion is mostly used by goblet cells, which secrete vesicles into a duct.
Goblet cell [4]
|TH||H3.04.03.0.00009, H3.04.03.0.00016, H3.05.00.0.00006|. Goblet cells are simple columnar epithelial cells that secrete gel-forming mucins, like mucin 5AC.[1] The goblet cells mainly use the merocrine method of secretion, secreting vesicles into a duct, but may use apocrine methods, budding off their secretions, when under stress.[2] The term goblet refers to the cell’s goblet-like shape
The goblet cell is highly polarized with the nucleus and other organelles concentrated at the base of the cell and secretory granules containing mucin, at the apical surface.[1] The apical plasma membrane projects short microvilli to give an increased surface area for secretion.[3]. Goblet cells are typically found in the respiratory, reproductive and gastrointestinal tracts and are surrounded by other columnar cells.[1] Biased differentiation of airway basal cells in the respiratory epithelium, into goblet cells plays a key role in the excessive mucus production, known as mucus hypersecretion seen in many respiratory diseases, including chronic bronchitis, and asthma.[4][5]
In the conjunctiva goblet cells are a source of mucin in tears and they also secrete different types of mucins onto the ocular surface. In the lacrimal glands, mucus is synthesized by acinar cells instead.[7]
Epithelium: What It Is, Function & Types [5]
The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body, lines body cavities and hollow organs and is the major tissue in glands. Epithelial tissue has a variety of functions depending on where it’s located in your body, including protection, secretion and absorption.
All substances that enter or leave an organ must cross the epithelial tissue first.. You have many different kinds of epithelial tissue throughout your body
In biology, a cell is the smallest unit that can live on its own. Cells make up all living organisms and the tissues of your body
Epithelium [6]
OBJECTIVES: At the end of this laboratory you should be able to:. Recognize and correctly name the eight types of epithelium.
Distinguish whether an epithelial type contains cilia or microvilli.. Identify and distinguish between cilia and microvilli both in light and electron micrographs (based on the type of epithelium in the light microscope and based upon structure at the EM level).
Recognize the junctional complex and its components, the zonula occludens, the zonula adherens and the macula adherens in electron micrographs.. Distinguish between multicellular and unicellular glands.

Epithelia: The Histology Guide [8]
The cells in epithelia have different shapes, and different types of epithelia have different numbers of layers of cells (from one to many). The shape of the cells, and their organisation are important to the particular function of each type of epithelia.
If a specialisation is present, then the type of specialisation present is included in the classification.. Read the classification rules below, then have a go yourself.
When sectioned at right angles to their basement membrane the cells in different epithelia have a variety of shapes:. A special form of epithelium, in which the cells can alter their shape
Histology Guide [9]
Epithelium forms continuous sheets of cells that line internal surfaces and cover the external surface of the body. It acts as a selective barrier that protects tissues
– Shape of surface cells (squamous, cuboidal or columnar). – Apical domain – surface that faces the lumen or the external environment
– Tight junctions (zonula occludens), adherens junction (zonula adherens), desmosomes (macula adherens), gap junctions. – Basal domain – surface that attaches to the basement membrane

Epithelial Tissue [11]
– Know the structure of apical specializations and their functions.. – Be able to correlate different types of epithelia to their functions.
Be able to identify the classes of epithelia underlined in the text below, and give some thought to why these different classes of epithelia have such different morphologies. The glass slide sets occasionally contain different stains or even different slides of the same tissue in place of the slide that you have in your set
Please try to look at the alternates by borrowing from your lab mates. Certain stains are much more instructive than others and different (alternate) tissues often help to explain functional changes.
Epithelium Description [12]
(C9-13) Slide 51: Ileum – fast green, hematoxylin & PAS. Its surface is covered with finger-shaped structures, called villi (C9)
Next, look for any modifications that should be added to its name. Examining the epithelium at high power reveals two stripes at the apical surface, one pink stripe and one green stripe (C10)
The green stripe is the microvillous border, and at the base of the microvilli there is a darker green line, the terminal web. The terminal web is interrupted at every intercellular boundary by a slight thickening called the terminal bar, where a junctional complex exists between the cells

Microvillus | Description, Anatomy, & Function [14]
Our editors will review what you’ve submitted and determine whether to revise the article.. microvillus, plural microvilli, any of numerous microscopic bristlelike protrusions that occur on the surface of a wide variety of cell types, including intestinal epithelial cells, neurons, photoreceptors (light-sensitive cells), and certain cells of the immune system, such as dendritic cells and lymphocytes
The polymerization of actin filaments potentially drives the protrusion of microvilli from the cell surface and contributes to the unique highly curved form of the membranes on which microvilli occur.. The curvature of microvilli protrusions and their enrichment with a variety of proteins and lipids influence and contribute to the diverse functions of microvilli
Other types of microvilli are involved in the detection of sound in the ear, where their movement, caused by sound waves, sends an electrical signal to the brain. In the immune system, microvilli are thought to serve a role in the transmission of signals involved in the activation of immune responses.
Knowledge @ AMBOSS [15]
Tissues are formed by cells and can be differentiated into four different types: connective tissue, muscle tissue, nerve tissue, and epithelium (epithelial tissue). Epithelium is a component of almost every organ in the body
Connective, muscle, and nerve tissue are addressed in the respective articles. Epithelium covers all inner and outer surfaces of the body (except joint cavities), namely the skin (epidermis) and all mucous membranes
Surface epithelium is named and classified according to various criteria (layers, cell shape, surface characteristics). Glandular tissue can be classified according to its location, shape, secretory mechanism, and the type of secretion associated with it (serous or mucinous)
Atlante di istologia [16]
This epithelium is composed by a single layer of cells which are wider than they are tall. Their nucleus is flat and they are disposed in order to create a thin surface
Here are some examples of simple squamous epithelium: the endothelium (that constitutes the tunica intima of blood vessels), the mesothelium (that constitutes serous membranes: pericardium, pleura and peritoneum), the epithelium constituting the renal capsule (Bowman’s capsule) of the renal corpuscle and the epithelium constituting alveolar walls.. Schematic drawing of the simple squamous epithelium.
You can see extremely flattened, stretched cells with a central lengthened nucleus. Cytoplasm can be found in small or large amount and it is outlined in panel B.
