Coloured SEM of human striated muscle
Striated muscle. Coloured scanning electron micrograph (SEM) of human striated muscle. Striated muscle occurs in all skeletal muscles and its movement is under voluntary control. It is composed of long muscle fibres made up of cylindrical myofibrils (green) containing contractile proteins. The parallel arrangement of the myo- fibrils is seen here. The regular pattern of the contractile proteins in the myofibrils produces characteristic stripes or striations (not seen). Infiltrating the myofibrils at these regular intervals is sarcoplasmic reticulum (globose, orange), the muscles specialized membrane system. Magnification: unknown

EDITORS COMMENTS
This print showcases a coloured scanning electron micrograph (SEM) of human striated muscle, providing an intricate glimpse into the fascinating world of anatomy. Striated muscle is found in all skeletal muscles and is responsible for voluntary movement. The image reveals long muscle fibres composed of cylindrical myofibrils, which are highlighted in a vibrant green hue. These myofibrils contain contractile proteins that enable muscular contraction. The parallel arrangement of the myofibrils creates a visually striking pattern, reminiscent of delicate stripes or striations. However, these distinct markings are not visible in this particular SEM capture. Intriguingly, infiltrating the myofibrils at regular intervals is the sarcoplasmic reticulum depicted as globose structures glowing orange. This specialized membrane system plays a crucial role in supporting muscle function. While the exact magnification remains unknown, this photograph provides an extraordinary level of detail that allows us to appreciate the complexity and beauty inherent within our own bodies. It serves as a reminder of the incredible intricacies that exist within our skeletal muscles and how they work harmoniously to facilitate movement. This remarkable image from Science Photo Library offers both scientific insight and aesthetic appeal, making it an ideal addition to any collection exploring topics such as muscle anatomy, skeletal structure, or human physiology without mentioning commercial use or specific companies involved with its production.
