Welcome to Disabilities-R-Us! < Disabilities-R-Us Structure of a Muscle Cell (Muscle Fibre) This page follows on from the more general page about the structure of muscle. Skeletal muscles consist of 100,000s of muscle cells (also known as 'muscle fibers') that perform the functions of the specific muscle of which they are a part. The diagram above shows some detail of the structure of a muscle cell. It illustrates the distinctive structure of muscle cells, including striated myofibrils (components of muscle cells only). It is also important to remember that the components essential for all cells (not all of which are illustrated in the diagram above) are also present in muscle cells. General components of Muscle Fibres/cells: The components of skeletal muscle cells that are specific to muscle tissue are myofibrils. More specialised components of Muscle Fibres (Muscle Cells): The components of skeletal muscle cells that are specific to muscle tissue are called myofibrils. Each myofibril consists of two types of protein filaments called 'thick filaments', and 'thin filaments'.
MadSciNet: The 24-hour exploding laboratory. ActionBioscience - promoting bioscience literacy Fundamental Biosciences Life sciences include disciplines of science that are concerned with the scientific study of life – including microbes, plants, and animals, including humans. Biology is an umbrella term for the natural sciences that study life, with the other life sciences serving as subfields. In our holistic approaches to health, life and wellbeing, the area of Life Sciences complements all areas of our website with a more scientific point of view to better understand the advances in bioscience and their profound implications. Also, in the area of Life sciences, we aim to promote the understanding of biodiversity of life and improve bioscience literacy to increase global ecological consciousness and promote bioscience education. Goals and Features of Bioscience on ICWB.com To achieve the beforementioned aims, this section features articles written by scientists, scientific educators and science students on a variety of bioscience-related subjects.
Human Body: Explore the Human Anatomy in 3D Different organs can work together to perform a common function, like how the parts of your digestive system break down food. We refer to an integrated unit as an organ system. Groups of organ systems work together to make complete, functional organisms, like us! There are 11 major organ systems in the human body. The circulatory system is a body-wide network of blood, blood vessels, and lymph. Learn more about these body parts in the circulatory system: Every tissue within the body requires oxygen to function. Learn more about these body parts in the respiratory system: The skeletal system gives the body its basic framework, providing structure, protection, and movement. The muscular system is comprised of the sum total of muscles throughout the body that move the skeleton, maintain posture through steady contraction, and generate heat through cell metabolism. The nervous system allows us to perceive, comprehend, and respond to the world around us.
