Within the past decade it has become apparent that HVEM offers the biologist a means to explore the three-dimensional structure of cells and/or organelles. Stereo-imaging of thick sections (e.g. 0.25-10 μm) not only reveals anatomical features of cellular components, but also reduces errors of interpretation associated with overlap of structures seen in thick sections. Concomitant with stereo-imaging techniques conventional serial Sectioning methods developed with thin sections have been adopted to serial thick sections (≥ 0.25 μm). Three-dimensional reconstructions of the chondriome of several species of trypanosomatid flagellates have been made from tracings of mitochondrial profiles on cellulose acetate sheets. The sheets are flooded with acetone, gluing them together, and the model sawed from the composite and redrawn.The extensive mitochondrial reticulum can be seen in consecutive thick sections of (0.25 μm thick) Crithidia fasciculata (Figs. 1-2). Profiles of the mitochondrion are distinguishable from the anterior apex of the cell (small arrow, Fig. 1) to the posterior pole (small arrow, Fig. 2).

Mid Palatal Suture

Rapid Maxillary expansion or palatal expansion as it is sometimes called, occupies unique niche in dentofacial therapy. Rapid Maxillary expansion (RME) is a skeletal type of expansion that involves the separation of the mid-palatal suture and movement of the maxillary shelves away from each other. RME effects the maxillary complex, palatal vaults, maxillary anterior and posterior teeth, adjacent periodontal structures to bring about an expansion in the maxillary arch. Morphogenesis and anatomical features of the upper jaw determine the choice of the method of rapid palatal expansion with narrowing of the upper dentition, as an effective method for eliminating congenital deformities of the maxillofacial region. The majority of dental transverse measurements changed significantly as a result of RME. The maturity of the maxillofacial structures determines the timing and degree of success of rapid palatal dilatation treatment.

Surgical Anatomy of the Ocular Adnexa is a beautifully and thoughtfully illustrated anatomical text that provides the ophthalmic surgeon or any surgeon working in the eyelid/orbital region with detailed yet concise, easy to read and understand descriptions of the anatomy in any particular region of the eyelid, orbit or nasolacrimal system. Throughout the text are clinical pearls and vignettes to help the reader appreciate why certain anatomical features are important to understand. Key anatomical concepts are highlighted and easy to visualize with real cadaver photos as well as the artists rendition of the same region. This book: - Develops a thorough understanding of the anatomy in the eyelid, orbit, nasolacriaml and periocular regions. - Fosters an appreciation of how knowledge of the anatomy leads to a better understanding of the pathophysiology of various disease processes involving the eyelid, orbit, nasolacrimal and periocular region. - Conveys the importance of anatomy in the surgical approach to various disease processes in the eyelid, orbit, nasolacrimal and periocular regions. This second edition will be an invaluable guidel to all those working in the eyelid, orbital, and nasolacrimal areas including residents, fellows and staff in ophthalmology, otolaryngology/head and neck surgery, plastic surgery and neurosurgeons working in and around the orbit.

Anatomical Features

Two new specimens of Periastron reticulatum Unger emend. Beck have been collected from the Erin Slate, Talladega Slate Belt, southern Appalachians. Preserved anatomical features provide a basis for an expanded understanding of the genus and provide a biostratigraphic basis for dating the uppermost unit of the Talladega Slate Belt.
