Introduction: Sembulingam Physiology PDF
“Essentials of Medical Physiology” is a comprehensive textbook written by K. Sembulingam and Prema Sembulingam. The book provides a detailed understanding of the human body’s various physiological processes and their mechanisms. It is primarily designed for medical students and healthcare professionals who need to have a thorough knowledge of human physiology to diagnose and treat various diseases. This article will cover the essential topics covered in the book in detail.
Cellular Physiology:
This section of the book covers the basic fundamentals of cellular physiology, including the structure and function of cells, cell membrane physiology, membrane transport, and cell signaling. It explains the role of various organelles in the cell and how they function together to maintain the cell’s homeostasis. The book also discusses the numerous signaling pathways that regulate cellular functions, including intracellular signaling, extracellular signaling, and intercellular communication.
Nerve and Muscle Physiology:
This section of the book covers the nervous and muscular systems’ physiology, including the structure and function of neurons, action potentials, synaptic transmission, and neural integration. It also covers the anatomy and physiology of skeletal, smooth, and cardiac muscles, including muscle contraction, excitation-contraction coupling, and muscle metabolism. This section is essential for understanding how the nervous and muscular systems work together to control body movements and functions.
Cardiovascular Physiology:
The physiology of the cardiovascular system, including the structure and operation of the heart, blood arteries, and blood circulation, is covered in this book chapter. It describes how blood pressure regulation, cardiac output, peripheral resistance, and blood flow to various organs and tissues are affected by these factors. The physiology of the heart cycle, including the electrocardiogram (ECG), cardiac output, and stroke volume, is also covered in the book.
Respiratory Physiology:
This section of the book covers the anatomy and physiology of the respiratory system, as well as the structure and function of the lungs, airways, and alveoli. It explains the mechanics of ventilation, gas exchange, and the regulation of respiration by the nervous and endocrine systems. This section also covers the various respiratory diseases and disorders, including chronic obstructive pulmonary disease (COPD), asthma, and pneumonia.
Gastrointestinal Physiology:
This chapter of the book covers the physiology of the gastrointestinal system, including the make-up and function of the digestive organs such the liver, pancreas, intestines, stomach, and mouth. It explains how nutrients are digested, absorbed, and metabolised as well as how hormones and brain impulses control these processes. This section also discusses the many gastrointestinal illnesses and conditions, such as peptic ulcers, gastroesophageal reflux disease (GERD), and inflammatory bowel disease (IBD).
Renal Physiology:
This section of the book covers the physiology of the urinary system, including the structure and function of the kidneys, ureters, bladder, and urethra. It explains the processes of filtration, reabsorption, and secretion of various substances in the nephron and the regulation of these processes by hormones and neural signals. This section also covers the various renal diseases and disorders, including chronic kidney disease (CKD), nephrotic syndrome, and renal calculi.
Endocrine Physiology:
This section of the book covers the physiology of the endocrine system, including the anatomy and function of the various endocrine glands, such as the pituitary, thyroid, parathyroid, adrenal, and pancreas. It explains the regulation of hormone secretion, the role of hormones in maintaining homeostasis, and the feedback mechanisms that regulate hormone levels. This section also covers the various endocrine diseases and disorders, including diabetes mellitus, hypothyroidism, and hyperthyroidism.
Integrative Physiology:
This section of the book covers the integration of various physiological processes in the body, including fluid and electrolyte balance, acid-base balance, temperature regulation, and exercise physiology. It explains the various mechanisms that the body uses to maintain homeostasis, such as feedback loops, feedforward mechanisms, and reflexes. This section also covers the various factors that can disrupt homeostasis, such as dehydration, electrolyte imbalances, and hyperthermia.
Clinical Physiology:
This section of the book covers the application of physiological principles to clinical practice, including the diagnosis and treatment of various diseases and disorders. It explains the various diagnostic tests and procedures used in clinical practice, such as blood tests, imaging studies, and electrocardiography. It also covers the various treatment modalities, including pharmacotherapy, surgery, and lifestyle modifications.
Conclusion:
Overall, K. Sembulingam’s Essentials of Medical Physiology is an essential resource for those looking to gain a deeper understanding of the human body. In addition, the book’s illustrations and diagrams help bring the concepts to life and provide a better understanding of how the body works.
