Question
Which of the following sentences about human muscle tissue is INCORRECT? [2 marks]A Cardiac muscle is only found within the heartB Both cardiac and skeletal muscle are striated, which means that they have a stripedappearanceC Skeletal muscle cells are connected by intercalated disks, which allows electrical signalto pass from one cell to anotherD Skeletal muscle cells are long and thin, and also known as muscle fibresE Smooth muscle is found within the walls of blood vessels, lymphatic vessels and thereproductive tract
Solution
Para responder a la pregunta, revisemos cada una de las afirmaciones sobre el tejido muscular humano:
A. "Cardiac muscle is only found within the heart" - Esta afirmación es correcta. El músculo cardíaco se encuentra exclusivamente en el corazón.
B. "Both cardiac and skeletal muscle are striated, which means that they have a striped appearance" - Esta afirmación es correcta. Tanto el músculo cardíaco como el esquelético son estriados, lo que significa que tienen una apariencia rayada.
C. "Skeletal muscle cells are connected by intercalated disks, which allows electrical signal to pass from one cell to another" - Esta afirmación es incorrecta. Las células del músculo esquelético no están conectadas por discos intercalados; estos discos son característicos del músculo cardíaco.
D. "Skeletal muscle cells are long and thin, and also known as muscle fibres" - Esta afirmación es correcta. Las células del músculo esquelético son largas y delgadas, y también se conocen como fibras musculares.
E. "Smooth muscle is found within the walls of blood vessels, lymphatic vessels and the reproductive tract" - Esta afirmación es correcta. El músculo liso se encuentra en las paredes de los vasos sanguíneos, vasos linfáticos y el tracto reproductivo.
Por lo tanto, la afirmación incorrecta es la C.
