This review uncovers motor endplate structure in different fiber types of vertebrate skeletal muscle, indicating distinctions across species.

To investigate the structure and localization of motor endplates in various vertebrate skeletal muscle fiber types across different species.
Review of morphological features of motor endplates in mammalian, avian, reptilian, amphibian, and fish skeletal muscles.
Utilization of high-resolution scanning electron microscopy to analyze motor endplate structure.
Classification of skeletal muscle fibers into twitch and slow types.
Twitch fibers are singly innervated with en plaque type endplates, whereas slow fibers are multiply innervated with en grappe type endplates.
The structure of motor endplates varies among the fiber types: large and complex in white fibers, small in red fibers, and intermediate in intermediate fibers.
Distinct morphological traits are observed across different species (mammals, birds, reptiles, amphibians, and fish).
