Muscle Physiology

Block II — Muscular Physiology

How it begins

El músculo esquelético representa aproximadamente el 40% de la masa corporal en el adulto y es responsable de toda la motilidad voluntaria, la postura y la generación de calor. Está formado por células multinucleadas llamadas fibras musculares (miocitos), que pueden medir varios centímetros de longitud. La comprensión de su funcionamiento es fundamental para la clínica: desde la anestesiología hasta la neurología,…
