Interrod enamel is histology histologically identified on microscopic views of tooth enamel . Because interrod enamel is located around enamel rod s, the areas of interrod enamel enhances the keyhole appearance of enamel rods by acting as its border. The location where the two areas of enamel meet is known as the rod sheath . All tooth enamel, including interrod enamel and enamel rods, is made by ameloblast s. However, interrod enamel is formed slightly sooner than enamel rods. Interrod enamel has the same composition as enamel rods. A distinction is made between the two because they differ in the direction of their crystalline patterns. References Cate, A.R. Ten. Oral Histology development, structure, and function. 5th ed. 1998.

Gnarled enamel is a description of tooth enamel enamel seen in histology histologic sections of a tooth underneath a cusp dentistry cusp . The appearance of enamel appears different and very complex under the cusp, but this is not due to a different arrangement of dental tissues. Instead, the enamel still has the same arrangement of enamel rod s. The strange appearance results from the lines of enamel rods directed vertically under a cusp and from their orientation in a small circumference. References Cate, A.R. Ten.

In actuality, there is no mesenchyme completely surrounded by dental lamina.

Tomes processes are a histology histologic landmark identified on an ameloblast , cells involved in the production of tooth enamel . During the synthesis of enamel, the ameloblast moves away from the Tooth enamel enamel , forming a projection surrounded by the developing enamel. Tomes processes are those projections and give the ameloblast a picket fence appearance under a microscope . They are located on the secretory, basal, end of the ameloblast. Terminal bar apparatus connects the Tomes Processes. Tonofilaments separate the developing enamel from the enamel organ. Gap junctions synchronise cell activation. The body of the cell between the processes first deposits enamel, which will become the periphery of the enamel prisms,then the tomes process will infill the main body of the enamel prism. More than one ameloblast contributes to a single prism. Tomes processes are distinctly different from Tomes fibers, which are odontoblastic processes that occupy dentinal tubules.

It lies above a condensation of ectomesenchymal cells called the dental papilla . Historically, enamel organ has been the term to describe this structure, but it was attempted unsuccessfully in recent years to change the name to dental organ in order to better represent its multiple functions apart from tooth enamel enamel formation.

mergeto Bronchiole date November 2009 The primary bronchioles arise from the tertiary bronchus tertiary bronchi . They are histologically distinct from the tertiary bronchi in that their walls do not have hyaline cartilage and they have Clara cell s in their epithelial lining. The epithelium starts as a simple columnar epithelium simple ciliated columnar epithelium and changes to simple cuboidal epithelium simple ciliated cuboidal epithelium as the primary bronchiole decreases in size. The diameter of the primary bronchioles is often said to be less than 1 mm, though this value can actually range from 5 mm to 0.3 mm. As stated, these bronchioles do not have hyaline cartilage to maintain their patency. Instead, they rely on elastic fiber s attached to the surrounding human lung lung tissue for support. The inner lining lamina propria of these bronchioles is thin with no glands present, and is surrounded by a layer of smooth muscle . As the primary bronchioles get smaller they divide into terminal bronchiole s. References Dudek, Ronald W. High Yield Histology , 3rd ed. 2004 . ISBN 0 7817 4763 5 Gartner, Leslie P. and James L.

The dental lamina is first evidence of tooth development and begins at the sixth week in utero or three weeks after the rupture of the buccopharyngeal membrane. It is formed when cells of the oral ectoderm proliferate faster than cells of other areas. Best described as an in growth of oral ectoderm , the dental lamina is frequently distinguished from the vestibular lamina , which develops concurrently. This dividing tissue is surrounded by and, some would argue, stimulated by ectomesenchymal growth. When it is present, the dental lamina connects the developing tooth bud to the epithelium of the oral cavity . Eventually, the dental lamina disintegrates into small clusters of epithelium and is resorbed. In situations when the clusters are not resorbed, this remnant of the dental lamina is sometimes known as the glands of Serres eruption cyst s are formed over the developing tooth and delay its eruption into the oral cavity. This invagination of ectodermal tissues is the progenitor to the later ameloblasts and Tooth enamel enamel while the ectomesenchyme is responsible for the dental papilla and later odontoblasts .
