During the bell stage, an extra layer of epithelium and stratum intermedium is added to the development of the tooth. Stratum intermedium contains coatings of flattened squamous cells that are held in the IEE and stellate reticulum They have, been described as originating through breakdown of the stellate reticulum of the enamel organs of developing teeth, but most of them probably are results of degenerative changes in reduced enamel epithelium.

The enamel organ is composed of inner and outer enamel epithelium, stratum intermedium and stellate reticulum. During the stages of odontogenesis, many physiological processes occur. These physiological processes include initiation, proliferation, differentiation, maturation and morphogenesis. Many of these processes overlap and are continuous.

It is generally seen in teenagers and only rarely after the age of 30 years. It is a well-circumscribed radiolucent tumor that has a predilection for the posterior jaws and malpositioned teeth. Treatment is enucleation and curettage

Lunt and Law concluded after reviewing the work of Kraus and Jordan and of Nomata that Table 9-1 should be modified. 4, 5 The sequence of calcification of the primary teeth should be changed to central incisor, first molar, lateral incisor, canine, and second molar. They determined that the times of initial calcification of the primary teeth are 2 to 6 weeks earlier than those given in Table 9-1 dental lamina slideshare.

Dentigerous cyst is the second most common odontogenic cyst. This develops within the normal dental follicle that surrounds an unerupted tooth, or from degeneration of the stellate reticulum, or an accumulation of fluid between the layers of the reduced enamel epithelium. The lining typically consists of flattened stratified epithelium

  1. Previously, stellate reticulum occupied this space. The inner and outer dental epithelia without the stellate reticulum is referred to as Hertwig epithelial root sheath, which is responsible for the size and shape of the root and eruption of the tooth (Fig. 13.31). 9. Figure 13.30
  2. stellate reticulum [5,6]. During intraosseous stage there is a coordinated translocation of the tooth into resorbed space, bone apposition at the DF fundus and simultaneous root elongation. Formation of the eruption pathway is completed soon after the cusps reach the alveolar crest and at this point the rate of eruption accelerates [7]

Inner enamel epithelium. Outer enamel epithelium. Stratum intermedium. Stellate reticulum. Together, these cell groups work to develop the enamel layer of the tooth. During the second event in this stage, the enamel epithelium folds into the future shape of the tooth crown, and the dental lamina starts to break down. 4 The FASEB Journal, FASEB's flagship publication, is highly cited and consistently ranked among the top biology journals globally. It features transdisciplinary original research covering all fields of biology at every level of organization: atomic, molecular, cell, tissue, organ, organismic, and population Tooth development is the complex process by which teeth form from embryonic cells, grow, and erupt into the mouth.

The dental papilla forms both the dental pulp (the soft tissue in the root chamber of the tooth that contains nerves, vessels, and connective tissue) and odontoblasts, which form the dentin of the tooth.

  4. The cells between the IEE and the stellate reticulum form a layer known as the stratum intermedium. The rim of the enamel organ where the outer and inner enamel epithelium join is called the cervical loop.[23] In summary, the layers in order of innermost to outermost consist of dentin, enamel (formed by IEE, or 'ameloblasts', as they move.
  5. The outer and inner epithelial layers become continuous (without stratum intermedium or stellate reticulum) in the area of the future cementoenamel junction and form a two-layered sheath, which grows into the underlying mesenchyme.

Saliva is a fluid secreted by the salivary glands that keeps the oral cavity moist and also coats the teeth along with mucosa. The salivary gland possesses tubuloacinar units, and these are merocrine. The functional unit of the salivary glands is the terminal secretory piece called acini with a roughly spherical or tubular shape. It also consists of branched ducts for the passage of the saliva. Injury to hepatocyte and bile duct cells lead to accumulation of bile acid inside the liver. This promotes further liver damage. Non-parenchymal cells such as Kupffer cells, fat storing stellate cells, and leukocytes (i.e. neutrophil and monocyte) also have a role in the mechanism [35]. Drug-related hepatotoxicity cannot be viewed as a single. At the same time, polygonal cells between outer and inner enamel epithelia begin to separate and form the delicate cellular network known as the stellate reticulum (SR), the spaces of which are filled with a mucoid fluid. Histologically, this material resembles Wharton jelly

Vascular Endothelium Is Well-Situated to Regulate Metabolic Homeostasis. Blood vessels are broadly divided into 2 categories, macrovasculature and microvasculature. 1 The macrovasculature is composed of large vessels, such as arteries and veins, and is responsible for carrying blood toward or away from organs. The microvasculature—small arterioles, capillaries, and venules—primarily. This article covers odontogenic tumours and cysts, which is a subset of oral pathology and can be grouped under the heading of head and neck pathology.. The general topic of head and neck pathology is covered in the head and neck pathology and head and neck cytopathology articles..

Enterohepatic recycling occurs by biliary excretion and intestinal reabsorption of a solute, sometimes with hepatic conjugation and intestinal deconjugation. Cycling is often associated with multiple peaks and a longer apparent half-life in a plasma concentration-time profile. Factors affecting biliary excretion include drug characteristics (chemical structure, polarity and molecular size. The pancreas is an organ of the digestive system and endocrine system of vertebrates.In humans, it is located in the abdomen behind the stomach and functions as a gland.The pancreas is a mixed or heterocrine gland, i.e. it has both an endocrine and a digestive exocrine function. 99% part of pancreas is exocrine and 1% part is endocrine. As an endocrine gland, it functions mostly to regulate. Summary. Regulation of the circulatory system to maintain a constant arterial pressure is critical in ensuring adequate perfusion to meet metabolic requirements of tissues. Blood pressure (BP) can be considered in the context of Ohm's law, whereby BP (analogous to voltage) is directly proportional to the product of cardiac output (current. Peripheral to the internal dental epithelium lie the stratum intermedium, stellate reticulum, and external dental epithelium, the last closely associated with the many blood vessels in the dental follicle.

Cataract in diabetic patients is a major cause of blindness in developed and developing countries. The pathogenesis of diabetic cataract development is still not fully understood.

[until a neuroscientist answers] it depends. the cortex has many different neuron types. and it has both big and small neurons of the same neuron type. so i think average loses too much info; the distribution is very important. e.g. pyramida.. The Liver. The human liver is both the largest internal organ (the skin being the largest organ overall) and the largest gland in the human body. It is a soft, pinkish-brown, triangular organ normally weighing 1.44-1.66 kg (3.2-3.7 lb). The liver has a wide range of functions including detoxification, protein synthesis, and the production. The cervical loop stem cell niche of incisors was first identified when label-retaining cells were found to be localized inside the stellate reticulum (Smith, 1980; Harada et al., 1999) and more recently by using in vivo genetic lineage tracing (Seidel et al., 2010; Juuri et al., 2012). This work also shows that the progeny of the stem cells.

the aquaporin family of water channels consists of 10 proteins cloned from mammals and many more from amphibians, plants, yeast, bacteria, and various lower organisms.
