The advantage of these systems is that they can function as a remote third ear, one that can be located close to the source of the desired sound. Amplified Telephones Designed for hearing-impaired people, these are special telephone handsets that amplify sound.
The most striking feature of skeletal muscle fibers is the presence of striations that are conspicuous in longitudinally sectioned fibers. The striations are due to the presence of myofibrils, which are cylindrical bundles of thick and thin myofilaments, organized into units of contraction called sarcomeres.he most striking feature of skeletal muscle fibers is the presence of striations that are conspicuous in longitudinally sectioned fibers.
