When performing myoplastic operations and surgical interventions on the thyroid gland, trachea and esophagus, information on the variant anatomy of the infrahyoid muscles, the features of their innervation and blood supply are of great clinical importance. Moreover, when additional muscles are attached to the thyroid gland, intraoperative bleeding can occur resulting in hematoma and tissue scarring in the postoperative period. There are fragmentary data in the literature on the variants of the structure and topography of the human infrahyoid area muscles. The specificity of branching nerves and blood vessels, their vascular-nervous relationships in a separate part of the sternohyoid, sternothyroid, thyrohyoid, and omohyoid muscles should be taken into account when performing rational incisions in the neck, moving both the flaps and the above muscles in plastic surgery. The purpose of study was to establish the anatomical variability and features of innervation and blood supply of the infrahyoid muscles of the neck in human foetuses of 4 – 10 gestational months age. Material and methods. The study was performed on 36 human foetuses, whose parieto-coccygeal length was 81.0 – 375.0 mm, without visible signs of anatomical abnormalities or anomalies in the cervical region. Thin sections of the structures from the anterior and lateral parts of the neck were prepared under the control of binocular magnifier, vascular injection technique, and morphometry. Foetal preparations weighing over 500.0 g were studied directly at Chernivtsi Regional Paediatric Pathological Bureau. Foetal preparations were taken from the Museum of M.G. Turkevich Human Anatomy Department, Bukovinian State Medical University. Results and discussion. The study demonstrated anatomical variability of the infrahyoid area muscles during the foetal period of human ontogenesis. Human foetuses were mainly found to have loose extending intramuscular branching of the nerves of the cervical loop in the infrahyoid muscles. The only exception is the inferior belly of the omohyoid muscle, where main nerve branching is found out. The distribution of nerves in the thickness of the infrahyoid muscles is uneven. Macroscopic examination revealed the smallest number of nerve branches was found within the middle third of the sternohyoid and upper third of the sternothyroid muscles. Arteries and nerves enter the sternothyroid and thyrohyoid muscles through the anterior surface, and the omohyoid and sternohyoid muscles enter mainly through the posterior surface of these muscles. The infrahyoid muscles are characterized by the main form of intramuscular branching of the arteries. The data on the peculiarities of intramuscular branching of arteries and nerves in the infrahyoid muscles we obtained, as well as the variant anatomy of the infrahyoid area muscles must be taken into account when performing a surgical access to the neck, or when operating on in the anterior cervical region, in particular myoplastic and reconstructive operations, in order to avoid muscle injuries.

Parameterized Model

A dynamic simulation model of the contractile function of the heart is presented. The contractile function simulation is based on the modeling of the muscle fibers' structure according to the Atlas of human anatomy and the use of parameters of their geometric shape as parameters that control the contraction. The basic concepts of the architecture of muscle fibers of the myocardium and the structure of the blood supply to the heart are investigated. An algorithm is developed for local parameterization of the contractile function of the heart, which mimics blood flow and conduction disturbances via special control functions. The algorithm of the simulation model is shown in the example of only the left ventricle of the heart but is embedded in the full three-dimensional model of the ventricular complex of the heart. The simulation model is implemented as a solid-state parameterized model in the Autodesk Maya tool environment, managed by a program in the embedded Python language. The result is compared with the results of the OpenCMISS software in favor of the latter. It is planned to continue work with the implementation of the most advanced concept of the myocardial architecture of Torrent-Guasp together with the networks of electrical excitation and blood supply.

High Voltage Electron

The high voltage electron microscope has many advantageous features in comparison with the ordinary electron microscope. They are a higher penetrating efficiency of the electron, low chromatic aberration, high accuracy of the selected area diffraction and so on. Thus, the high voltage electron microscope becomes an indispensable instrument for the metallurgical, polymer and biological specimen studies. The application of the instrument involves today not only basic research but routine survey in the various fields. Particularly for the latter purpose, the performance, maintenance and reliability of the microscope should be same as those of commercial ones. The authors completed a 500 kV electron microscope in 1964 and a 1,000 kV one in 1966 taking these points into consideration. The construction of our 1,000 kV electron microscope is described below.

Nuclear Magnetic

Much progress in nuclear magnetic resonance microscope has been made in the last few years as a result of improved instrumentation and techniques being made available through basic research in magnetic resonance imaging (MRI) technologies for medicine. Nuclear magnetic resonance (NMR) was first observed in the hydrogen nucleus in water by Bloch, Purcell and Pound over 40 years ago. Today, in medicine, virtually all commercial MRI scans are made of water bound in tissue. This is also true for NMR microscopy, which has focussed mainly on biological applications. The reason water is the favored molecule for NMR is because water is,the most abundant molecule in biology. It is also the most NMR sensitive having the largest nuclear magnetic moment and having reasonable room temperature relaxation times (from 10 ms to 3 sec). The contrast seen in magnetic resonance images is due mostly to distribution of water relaxation times in sample which are extremely sensitive to the local environment.

Endoneurial Blood Flow

The blood supply (vasa nervorum) to peripheral nerves is composed of an interconnected dual circulation. The endoneurium of nerve fascicles is maintained by the intrinsic circulation which is composed of microvessels primarily of capillary caliber. Transperineurial arterioles link the intrinsic circulation with the extrinsic arterial supply located in the epineurium. Blood flow in the vasa nervorum is neurogenically influenced (1,2). Although a recent hypothesis proposes that endoneurial blood flow is controlled by the action of autonomic nerve fibers associated with epineurial arterioles (2), our recent studies (3) show that in addition to epineurial arterioles other segments of the vasa nervorum are also innervated. In this study, we examine blood vessels of the endoneurium for possible innervation.
