Answer:
Acetilcolina
Explanation:
La acetilcolina es un neurotransmisor excitatorio producido por neuronas del sistema nervioso periférico, es decir, células nerviosas que conectan el sistema nervioso central (SNC) con los diferentes órganos. La unión de acetilcolina a receptores específicos localizados en células del músculo esquelético conocidos como 'receptores nicotínicos' desencadena la contracción del músculo. Los receptores nicotínicos pertenecen a una superfamilia de proteínas de canales iónicos activados a través de la unión a acetilcolina, lo cual desencadena la despolarización de células musculares esqueléticas. Por otra, parte, la acetilcolina también posee un rol inhibitorio en células musculares cardíacas, donde su unión a receptores especifícos llamados 'receptores muscarínicos' disminuye la frecuencia cardíaca.
