Epithelium

Stem cell function Over the course of human history, medicine has come along way. Centuries ago, we thought that he body was composed of different liquids called humors and if you were unlucky to get sick during this time, your blood would have been withdrawn in a process known as "blood-letting". In modern time, we can give antibiotics, perform open-heart surgery and even operate on the brain. However, one of the newest advances in medicine is stem cell research, which is a promising new field…

The goblet cells of the intestinal epithelium secrete layers of mucus that prevent microbiota from contacting the epithelium too closely. The outer layer of mucus houses a large concentration of microbes whereas the inner mucus layer cannot be penetrated. However, because of the huge diversity and quantity of gut microbiota there…

requires three incisions to separate the pocket lining from the tooth surface. The initial incision dissects the pocket epithelium and portions of the subepithelial connective tissue. The gingiva is then reflected using the elevator, but only to the extent that the alveolar crest can be visualized. The second incision is sulcular around each tooth. This separates the pocket epithelium from the root surface to the base of the pocket. The final incision is horizontal and serves to atraumatically…

will test if the aromatherapy scents of jasmine and sandalwood help the brain’s speed and accuracy in completing a puzzle. The sense of smell begins in the back of the nose where millions of sensory neurons lie on a tissue called the the olfactory epithelium. As soon as an odor molecule binds to a receptor, it sends an electrical signal the olfactory bulb, which is where the smell is identified. Then, the thalamus which is the key relation station for sensory information sends the smell…

travels towards the stomach so that it can be broken down which then the body uses for energy. The nucleus controls the cell activities inside the cell. Mitochondria are needing to give energy to the cell and tissue. The columnar and squamous epithelium cell are found in the lining of the oesophagus.The mitochondria and lysosomes is used in the digestion system as an organelle is that the lysosome act as an enzyme which helps to break down the food or any of the…

Today is the best day! I went inside a giant’s respiratory system and it was awesome. I entered the respiratory system from the nasal cavity. The nasal cavity is part of the respiratory system. The nose is the primary opening for the respiratory system. Have you ever wondered how it works? The term "nasal cavity" can refer to each of the two sides of the nose or to the two sides combined. The two nasal cavities condition the air to be received by the other areas of the respiratory tract. Owing…

Epithelium cells are cells that line the body’s organs and when they are improperly functioning, this can lead to problems with the organs. Normal epithelial cells mucus that protects the body’s tissues. The epithelial cells in cystic fibrosis patients don’t…

humor, functions of the humors, origin and also pathology related to them. PHYSIOLOGY OF THE AQUEOUS HUMOR The aqueous humour is a transparent fluid similar to plasma, but containing low protein concentrations. It is secreted from the ciliary epithelium (a structure supporting the lens). It is located in the anterior and posterior chambers of the eye, the space between the lens and the cornea. It flows through the narrow cleft between the front of the lens and the back of the iris, to escape…

Cholesteatomatous otitis media is a special variety of chronic otitis media; it can be classified into several types: congenital, primary and secondary acquired, recurrent and residual types. The congenital cholesteatoma is a pearly white mass medial to an intact tympanic membrane with normal tympanic membrane, without any ear discharge or ear drum perforation or any otological procedure in the past [1]. Primary acquired cholesteatoma starts with an intact pars tensa and proceeds to the…

reversible when exposure to perchlorate ceases. Therefore, the negative impact is hypothyroidism (Urbansky, 2002). Perchlorate additionally influences other tissues in which NIS is known to be present inside the skin, gastrointestinal tract, breast epithelium, mammary gland, and placenta. The presence of perchlorate decreases the synthesis of circulating thyroid hormones within the adult and reduces their placental transfer to the fetus in pregnant ladies. Iodide uptake inhibition is taken into…
