Son músculos antagonistas (unos realizan flexión y otros extensión) los siguientes: * 5 puntos Trapecio- deltoides Bíceps- tríce
Lena [83]

Answer:

Bíceps- tríceps

Explanation:

Los músculos trabajan para generar movimiento mediante la contracción de células musculares. El bíceps y el tríceps son músculos antagonistas presentes en el brazo. Cuando el brazo se acorta, el bíceps funciona como agonista (es decir, se contrae) y hace que los tendones que tiran de los huesos del antebrazo puedan doblarlo. Durante este movimento, el triceps funciona como antagonista, encontrándose en estado de relajamiento. Por otra parte, durante el estiramiento del brazo, las funciones de estos músculos se invierten, con lo cual el tríceps (agonista) se contrae  y el bíceps (antagonista) se relaja.
