Epithelial Tissue: A Comprehensive Guide to Structure and Function
Epithelial tissue is one of the fundamental building blocks of the human body, playing a crucial role in protecting organs, facilitating absorption, and enabling secretion. Whether forming the outer layer of the skin or lining internal cavities and glands, epithelial tissues serve as the body’s first line of defense and a gateway for vital functions. […]
The post Epithelial Tissue: A Comprehensive Guide to Structure and Function appeared first on Cancer biology research.
This document was complied for the APES1000A course (WITS) but is comprehensive enough to serve as a valuable guide + supplement for any 1st year biology half course. The notes contain details and diagrams on the following sub sections: Tissue types & cell junctions Epithelial tissue Connective tissue Nervous tissue Muscle tissue Skin as an organ
Epithelial Tissue. Epithelial tissue covers the body’s outer surface and lines the internal closed cavities (including blood vessels) and body tubes that communicate with the exterior (gastrointestinal, respiratory, and genitourinary tracts). Epithelium also forms the secretory portion of glands and their ducts. Origin and Characteristics Epithelial tissue is derived from all three embryonic layers. Most epithelia of the skin, mouth, nose, and anus are derived from the ectoderm. Linings of…
Chronic Pain, Inflammation, Gluten, Autoimmunity, Dysbiosis, and the "Leakies"
If you've ever wondered about "The Leakies" (Leaky Gut, Leaky Lung, Leaky Brain, Leaky Cord, etc) or if you simply struggle with chronic pain or chronic health conditions, this post is for you.
Tissue Types: Connective, Muscle, Nervous Vector Image on VectorStock
Detailed depiction of various tissue types: connective, muscle, and nervous. Close-up views of cellular structures, including epithelial, muscle, and neuron components. Suitable for educational and scientific reference. Download a free preview or high-quality Adobe Illustrator (ai), EPS, PDF vectors and high-res JPEG and PNG images.
Epithelial tissues are classified by the number of cell layers (simple, stratified, pseudostratified), the cell shapes (squamous, cuboidal, columnar), and the functions of the cells.
Virtual histology lab where students learn how to identify basic types of tissue, and view slides of body tissues and cells that represent each type of tissue.
