DNA from the Beginning -animated experiments
DNA from the Beginning is organized around key concepts. The science behind each concept is explained by: animation, image gallery, video interviews, problem, biographies, and links. DNAftb blog: It's the season of hibernation, something I've always wished I could do.
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.

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.
