Ciliated pseudostratified columnar epithelia is the type of respiratory epithelium found in the linings of the trachea as well as the upper respiratory tract.

Ciliated pseudostratified columnar epithelia is the type of respiratory epithelium found in the linings of the trachea as well as the upper respiratory tract. ... Pseudostratified columnar epithelia are found forming the straight, tubular glands of the endometrium in females.

…cilia, pseudopodia are responsible for amoeboid movement, a sliding or crawlinglike form of locomotion. The formation of cytoplasmic projections, or pseudopodia, on the forward edge of the cell, pulling the cell along, is characteristic of the microscopic unicellular protozoans known as amoebas.

The majority of the respiratory tree, from the nasal cavity to the bronchi, is lined by pseudostratified columnar ciliated epithelium. The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.

Most of the respiratory passageways, from the nasal cavity through the bronchi, are lined by ciliated, pseudostratified columnar epithelium with goblet cells. Bronchioles are lined by simple cuboidal epithelium. (Lung alveoli, in contrast, are lined by very thin simple squamous epithelium.)

Ciliated Epithelium is a type of Epithelial Tissue. The ciliated epithelium is found in the inner liningsurface of the fallopian tubes, bronchioles etc. The ciliated epithelium cells are columnarepithelial cells with cilia. Their main function is to help in the movement of material in one direction.

Cilia and Flagella. Cilia and flagella are motile cellular appendages found in most microorganisms and animals, but not in higher plants. In multicellular organisms, cilia function to move a cell or group of cells or to help transport fluid or materials past them.

Pseudostratified Ciliated Columnar Epithelium. The cells that comprise the epithelial membranes are variously shaped and are named accordingly. As implied by their moniker, columnar epithelial cells are taller than they are wide, appearing like numerous miniature pillars.

STRATIFIED CUBOIDAL AND STRATIFIED COLUMNAR EPITHELIUM: Also observe some stratified cuboidal epithelium lining the larger ducts found in this section (typically lying within connective tissue septa).

The stomach wall, with simple columnar epithelium visible as a lining at the top. A simple columnar epithelium is a columnar epithelium that is uni-layered. In humans, a simple columnar epithelium lines most organs of the digestive tract including the stomach, small intestine, and large intestine.

Simple columnar epithelium consist of a single layer of cells that are taller than they are wide. This type of epithelia lines the small intestine where it absorbs nutrients from the lumen of the intestine. Simple columnar epithelia are also located in the stomach where it secretes acid, digestive enzymes and mucous.

A is correct. Cilia are found on eukaryotic cells. Prokaryotes, such as bacteria, have flagella for locomotion. Eukaryotic flagella are similar to cilia in both structure and function.

Simple columnar epithelium forms the lining of some sections of the digestive system and parts of the female reproductive tract. Ciliated columnar epithelium is composed of simple columnar epithelial cells with cilia on their apical surfaces.

Pseudocoelom refers to the false body cavity. It is filled with fluid and the members of protostomes are known to be pseudocoelomate in nature. Blastocolemomate is another term for pseudocoelomate. The absence or negligible mesodermal lining distinguishes the pseudocoelom from the true coelom.

A cilium is an organelle found in eukaryotic cells. Cilia are slender protuberances that project from the much larger cell body. ... A flagellum is a lash-like appendage that protrudes from the cell body of certain prokaryotic and eukaryotic cells.

The term pseudostratified is derived from the appearance of this epithelium in section which conveys the erroneous (pseudo means almost or approaching) impression that there is more than one layer of cells, when in fact this is a true simple epithelium since all the cells rest on the basement membrane.
