A alternativa correta é a letra b) É formado por células grandes e polinucleadas com um retículo sarcoplasmático bem desenvolvido. As fibras musculares esqueléticas são multinucleadas e têm um arranjo paralelo, com estrias transversais que dão a aparência estriada. O retículo sarcoplasmático é uma organela importante para a contração muscular, pois armazena e libera íons de cálcio, que são necessários para a contração muscular.
