24 paź 2023 · The main classifications of epithelium are simple and stratified, each one being further divided into several subtypes according to two main factors: cell shape and apical surface specialization. This article will describe stratified (multi-layered) epithelium, focusing on its general characteristics and each major sub-type.
3 sie 2023 · Functions of the stratified columnar epithelium. The stratified epithelium has multiple layers of cells that aid in the protection of the underlying tissues. Additionally, based on the location of the tissues, they perform a function of limited secretion. Protection. The primary function of stratified epithelium is protection.

27 paź 2022 · Here we propose node-centric expression models (NCEM) to improve cell communication inference through the use of spatial graphs of cells to constrain axes of cellular communication.
Explain the general structure and function of epithelial tissue. Distinguish between tight junctions, anchoring junctions, and gap junctions. Distinguish between simple epithelia and stratified epithelia, as well as between squamous, cuboidal, and columnar epithelia. Describe the structure and function of endocrine and exocrine glands.
17 lut 2023 · Gap junctions are communicating junctions found throughout the lateral domain, creating channels that allow small molecules and ions to pass between adjacent cells.
These cells change morphology as they move toward the surface and are ultimately sloughed off. They are called "stratified" because there are multiple cell layers, and "squamous" because the outermost layer of cells is flattened. There are two subclasses: 1. Stratified squamous nonkeratinizing epithelium
