  All About Muscles: Types, Structure, and Contractile Proteins Explained The act of movement , or changing position by one or more parts of the body, is a vital feature of living organisms. The study of movement is called Kinesiology , while the scientific study of muscles is known as Myology or Sarco-logy . Muscles are specialized tissues that help us perform different kinds of physical activity—from walking to heartbeat regulation. Let’s understand the types of muscles , structure of muscle fibers , and contractile proteins that make movement possible. Types of Muscles Muscles can be classified into three main types: Voluntary or Skeletal Muscles Visceral or Smooth Muscles Cardiac Muscles Let’s begin with voluntary muscles , which we can control by our will. 💪 Need Detailed Notes on Muscle Types & Proteins? Confused between skeletal, cardiac, and smooth muscles? Want clarity on actin, myosin, sarcomere structure and muscle contractions? Get conci...

Understanding Blood Components, Rh Factor, and Lymph: A Vital Look into Human Circulation The human body is a complex system, and one of the most essential components sustaining life is blood. Blood not only transports oxygen and nutrients to various parts of the body but also plays a crucial role in defense, waste removal, and temperature regulation. Let’s explore the vital components of blood, the significance of Rh factor in transfusions and pregnancy, and the role of lymph in maintaining body balance. What Is Blood? Blood is a special connective tissue composed of a liquid matrix called plasma and formed elements such as red blood cells (RBCs), white blood cells (WBCs), and platelets. Plasma: Plasma is a straw-colored liquid that constitutes about 90–92% water and 6–8% proteins . These proteins include fibrinogen , globulins , and albumin . Fibrinogen plays a key role in blood clotting . Globulins are involved in the defense mechanism of the body. Plasma also c...
