hola buenas tus videos están muy interesantes, no se si ya tengas planeado alguno de: -Sistema Músculo esquelético superior -Sistema Músculo esquelético inferior ya sea que venga junto o separado músculos y esqueleto como en el caso de craneo, la verdad es que me sirve mucho de apoyo para mis clases 🙂
muy buenos videos, pero el volumen siempre es súper bajo, por más que alzo el volumen no se escucha, es frustrante, espero se pueda mejorar en esa situación

ME ENCANTO EL VIDEOOO❤️ aunque el audio al inicio se escucha muy suave :(
MUY BONITO VIDEO❤️ pero cómo haces todos esos dibujos? Usas una app? O los haces tú?
Hola podrías hacer un video de los músculos del abdomen?
