Fusiform Muscles | Spindle-shaped with a central belly that tapers to tendons on each end. Example: Brachialis/Brachioradialis |
Strap Muscles | Uniform in diameter; enables a focusing power on small, bony targets. Example: Sartorius |
Radiate Muscles | Triangular, fan-shaped, or convergent; combined arrangement of flat and fusiform; they originate on a broad surface and converge onto a tendon. Example: Pectoralis Major/Trapezius |
