It lies anterior to the vertebral column and posterior to the sternum. 2. BASIC STRUCTURE OF ARTERY AND VEIN Blood vessels are channels which help blood to be distributed to the rest of the body. The vessels make up two systems which are closed that begins and ends at the heart. However, based on the structure and function, the vessels are put into categories such as arteries and veins.
There are two types of SASC interactions observed by Smart Home Health Care. A composition pattern of three sensor nodes with different duties; ECG, thermometer and Patient activities, which are composed only in one SASC with the patient role. Instead of addressing the subcomponents, the SAS Cells can contact with the Patient
3.8 NEPHROLOGY Nephrology refers to a branch in medicine, studying with the diagnosis of diseases of kidneys and the treatment of these diseases. Kidney anatomy ???? 3.8.1 The micro-structure of the Juxtaglomerular complex and its function. The Juxtaglomerular complex refers to a region of a nephron which is specialized, where the afferent arteriole as well as the Distal Convoluted Tube (DCT) meet each other directly and making contact. It consists of the following: The Juxtaglomerular complex is made up of Juxtaglomerular cells of the afferent arteriole, which is smooth muscle cells that’s modified which includes renin.
The roles are as follows for the bacterial cells, the structure flagella are the swimming movement of the cell, pili stabilizes the cells during DNA transfer, the capsules are used as protection for the cell when a method of killing or digestion is happening. The cell wall confers rigidity and the shape they have, the plasmic membranes are the barriers and the location for the enzyme systems which produces energy. The ribosomes like animal and plant is the factor for protein synthesis. The other functions like the Chromosomes and the plasmid make up the DNA of the cell. Explain how bacteria cells make energy for cellular processes.
Knowledge regarding point of bifurcation of sciatic nerve plays a novel role in clinical practice by neurologists, surgeons, anaesthetists and radiologists. The aim of this study is to find the level of division of sciatic nerve and its clinical importance. MATERIALS AND METHODS: The study was a cross sectional one conducted in 32 cadavers(totally 64 lower limbs) in the department of anatomy at Government Stanley medical college, chennai and Government mohan kumaramangalam medical college,salem. The cadavers were dissected from the gluteal region to the transverse popliteal crease to expose the nerve and the piriformis muscle to determine the route of exit of the sciatic nerve. RESULTS The sciatic nerve exited under the piriformis as an undivided nerve and divided at the upper angle of popliteal fossa in 60 lower limbs.
PHYSICO-CHEMICAL, MORPHOLOGICAL AND TOPOGRAPHICAL CHARACTERIZATION OF MATERIALS INTRODUCTION: Biological evaluation and identification of the medical device is done by checking the three properties, they are Physicochemical, morphological and topographical . The evaluated data is used in a) Assessing the overall biological evaluation of a medical device (ISO 10993); b) Screening of potential new materials and/or processes for suitability in a medical device for a proposed clinical application. The compositional characteristics of the materials of manufacture are mainly under the control of the suppliers of these materials. However, other characteristics are chiefly influenced by the requirements to be met by the finished medical device
The instructions for the order of amino acids are made by the genes in an organisms cell. A process called DNA transcription makes up the sequence of the amino acids and then a specific protein is produced. Each protein structure has a specific function in it. Changing the structure will then change its function since it rearranges everything in the protein structure. Proteins are there for an essential part of the body, since it helps form body tissues, like muscles, organs and is used within many biological processes as well.
Introduction: Physiology is that branch of biology which deals with the functions of living systems. It also seeks to understand the individual development of functions and their alternation and adaptation with the continuously changing environments. The microscopic organisms often rely on molecular diffusion to provide them with nutrients and to remove waste products from them, whereas large organisms require more efficient means of transporting materials within their bodies. This transportation is accomplished using flowing liquids and gases. For example, Oxygen is swept into the lungs through a network of airways wherein the Oxygen diffuses into blood across the walls of alveoli and is then pumped by the heart through an extensive network
Introduction: This part of ISO 10993 details sample preparation methods and gives requirements and guidance foe the selection of reference materials for the biological evaluation of medical devices. The methods of sample preparation should be appropriate for the biological evaluation and materials to be evaluated. The biological test method requires the extraction solvents, selection of materials and conditions. Scope: This part of ISO 10993 focuses on the following: Selection of test sample Selection of representative portions from a device Preparation of test sample Experimental control Selection and requirements, for reference materials Extract preparation General requirements: While designing and preparing the test samples as described
On the basis of Sensor Placement: Strip Sensors, Wearable Sensors, Implantable Sensors, Invasive/Non-Invasive sensors, Ingestible Sensors. Biomedical Sensors Kits Available in Market for Patients Diagnostics Biosensor is a kind of device which senses biomaterial and its concentration, and which converts the biosignal into electrical signal. Special features of biosensor are the following: 1. Biological active material immobilized is used as catalyst, and expensive reagents could be repeatedly used to detect same biological parameters. 2.
