There are three types of epithelial cells, which differ in their shape and function. Squamous- thin and flat cells Cuboidal- short cylindrical cells, which appear hexagonal in cross-section Columnar- long or column-like cylindrical cells, which have nucleus present at the base On the basis of the number of layers present, epithelial tissue is divided into the simple.

This epithelial layer has mucus producing goblet cells that are only visible at high magnification. Underneath the epithelium is the lamina propria that contains submucosal glands that also produce mucus. The next layer is the hyaline cartilage, followed by the smooth muscle layer in this video we're going to talk a little bit about cell junctions cell junctions are basically things that connect cells to other cells and they often occur in epithelial tissue we're going to talk about three major types of cell junctions today the first tight junctions the second desmosomes and the third gap junctions so starting off with tight junctions let's say we have two cells like this so tight junctions basically connect the two cells together and it's kind of like a glue that.

Simple epithelial tissue. Its cells are organized in one layer , such as Simple squamous tissue, Simple cuboidal tissue and Simple columnar , Simple squamous tissue consists of one layer of flattened cells such as the lining ( endothelium ) of the blood capillaries and the wall of alveoli in the lungs The epithelium of the gastrointestinal (GI) tract undergoes constant rapid renewal. This process is an important mechanism of mucosal protection throughout the GI tract because it maintains the functional integrity of the epithelium and is also necessary for the repair of mucosal injury

Glands consist of parenchyma of glandular epithelium, which forms the secretory portions of glands, surface epithelium, which forms the duct system, and a stroma of connective tissue. Glandular tissue can be divided into exocrine and endocrine glandular tissue. Exocrine glands produce secretions to free surfaces, whereas endocrine. Tight junctions, also known as Zonula Occludens, are cell-cell adhesion complexes that play a role in the organization of epithelial tissue. By forming a meshwork of membrane contacts around the cell, tight junctions demarcate the apical region from the basolateral region, thereby serving as a physical barrier within the membrane and contributing to the establishment of cell polarity

The epithelial cells from the cervical loop epithelium region were obtained from the porcine third molar tooth (Figure 27.4 a).

Tight junctions are required for cell adhesion in various tissues of the body. These structures are seen to be present on the epithelium cells that form the internal lining of the body. These are usually of one or two layers of cells. Recent studies have also highlighted their role in barrier function in the skin as well Shared by all layers of the skin and its cells to do the following vital functions: 1) protection from inflammation and fluid. leakage. 2) Save and regulate body temperature by sweating. 3) protection from the sun's rays. 4) protect the internal organs of the body. and improves the external appearance

While the trigeminal nerve (CN V) is largely a sensory nerve, it also mingles in the realm of motor supply Functions of testis. The testicle (testis) contributes to the synthesis of sex hormones (androgens such as testosterone) and is the production site of male gametes (sperm). The sperm cells produced in the testis are stored in the epididymis. During ejaculation, they are released through the urethra via the vas deferens together with a secretion from the prostate and the glandula vesiculosa
