Question

9) The opposite graph represents the diameters of components of a skeletal muscle: Which of the following are surrounded by a membrane from outside? A) (1) and (5) B) (2) and (4) C) (3) and (4) D) (4) and (1) Diameter L.II. (1) (2) (3) (4) (5) S Components of the muscle​

Answer 1

The components surrounded by a membrane from outside are (2) and (4). Hence the correct option is b.

In the given graph representing the diameters of components of a skeletal muscle, components (2) and (4) are surrounded by a membrane from the outside. This likely refers to structures like muscle fibers or cells, which are encapsulated by a plasma membrane or sarcolemma. The sarcolemma surrounds the muscle fibers and is essential for maintaining the structural integrity of the muscle cell.

The other components, such as (1), (3), and (5), may represent structures like blood vessels or connective tissue elements, which are not typically encapsulated by a membrane in the same way as individual muscle fibers. The identification of (2) and (4) as components surrounded by a membrane emphasizes the importance of the cellular structure in the context of skeletal muscle. Hence the correct option is b.
