What are the characteristics, location, and function of striated cardiac muscle?
The striated cardiac muscle is present in the heart.
It acts in the contraction of this organ, allowing the pumping of blood throughout the body.
The striated cardiac muscle is composed of elongated and branched cells that present transverse striations, as in skeletal striated muscle tissue.
Unlike skeletal striated muscle tissue, these cells have one or two nuclei located in the center of the muscle fiber.
a) Only I and II are correct.
b) Only II, III, and IV are correct.
c) All statements are correct.

As características do músculo cardíaco estriado são as seguintes: - Ele está presente no coração. - Ele atua na contração desse órgão, permitindo o bombeamento de sangue por todo o corpo. - O músculo cardíaco estriado é composto por células alongadas e ramificadas que apresentam estriações transversais, assim como o tecido muscular estriado esquelético. - Ao contrário do tecido muscular estriado esquelético, essas células possuem um ou dois núcleos localizados no centro da fibra muscular. Portanto, todas as afirmações (I, II, III e IV) são corretas. A alternativa correta é a letra c) Todas as afirmações são corretas.
