An Introduction to Medical Biophysics by Parkash Parveen (1998) Edition : 1/e
DOI : 10.5005/jp/books/11603   ISBN:9788171795932

Medical Biophysics deals with applications of physical ideas and concepts enshrined in mechanics, hydrostatics, hydrodynamics, optics, acoustics, electrodynamics and radiological physics to medical sciences. Some aspects of biophysics are indistinguishable from biochemistry, physiology, medical physics, nuclear medicine, biomedical engineering and biotechnol... [More]

Chapter-01 Basic Concepts by Thayalan Kuppusamy (2017) Edition : 2/e

Physics is a science dealing with nature. It is concerned with the study of two concepts, matter and energy, and how they interact with each other. Matter is one, which occupies space and it is made up of molecules or atoms, e.g. copper, rubber, water and air. Matter exists in the form of solid, liquid, gas, liquid crystal and plasma state. Matter can be con... [More]

   Chapter DOI:10.5005/jp/books/11603_1      

The interaction between macromolecules, solutes, solvents, electrolytes and colloids in human body has been analysed in this chapter. The most important physical forces at work in living system include osmotic pressure, surface tension and viscosity. Any disturbance in the action of these forces inflicts illness that often comes to the attention of an astute... [More]

Chapter-02 Atomic Structure and Electronics by Thayalan Kuppusamy (2017) Edition : 2/e

The smallest particle of an element is an atom, which forms the fundamental unit of matter. The atoms are very small and its diameter is of the order of 10–10 m. Every atom possesses a central core called a nucleus, which is positively charged. The diameter of the nucleus is of the order of 10-15 m. This chapter discusses the atom, which includes atomic numb... [More]

Chapter-02 Pressure in Fluids: Its Measurement and Implications by Parkash Parveen (1998) Edition : 1/e
DOI:10.5005/jp/books/11603_2      

Pressure measurement has remained an important and feasible adjunct to clinical practice and scientists have sought better ways to measure it from desired points in the human body. Successful pressure monitoring has acquired an established role as it permits the accurate evaluation of the stage of the disease in heart, lung or other organ. This chapter is de... [More]

Chapter-03 Biomechanics of Muscle Contraction by Parkash Parveen (1998) Edition : 1/e
DOI:10.5005/jp/books/11603_3      

Muscle is the largest single tissue in human body, comprising more than 40% body mass in adults. The contraction of muscles is the most apparent and dramatic macroscopic signs of life and have therefore excited the imagination since the times of ancient. It is ironic that after using muscles day and night, for many thousands of years homo-sapiens still does ... [More]

Chapter-03 Electricity and Magnetism by Thayalan Kuppusamy (2017) Edition : 2/e

This chapter aims to introduce the electricity and magnetism. The term “electric” is derived from the Greek word “electron”. Any solid rubbed with suitable materials will attract light objects, e.g. an ebonite rod rubbed with fur or a glass rod rubbed with silk will attract small pits of paper. Therefore, the agency which is responsible for this property is ... [More]

Chapter-04 Electromagnetic Induction by Thayalan Kuppusamy (2017) Edition : 2/e

According to Faraday, current can be produced in a closed conductor, whenever there is a change in the magnetic flux passing through the conductor. The current exists only as long as the change takes place. The current produced in the conductor in this way is called an induced current. The electromotive force (emf) that produces the current is called an indu... [More]

   Chapter DOI:10.5005/jp/books/11603_4      

Membranes are asymmetric sheet like enclosed structures with an inside and an outside. These sheet like structures are thermodynamically stable but electrically and metabolically active. By forming closed compartments around cellular protoplasm, membranes separate one cell from another, thus permitting cellular individuality. Membranes act as barrier, with s... [More]
