Muscle fibers can be arranged into two basic structural patterns, fusiform and pinnate. Most human muscles are fusiform, with the fibers largely arranged parallel along the muscle's longitudinal axis.
In many of the larger muscles the fibers are inserted obliquely into the tendon, and this arrangement resembles a feather. The fibers in a pinnate (feather) muscle are shorter than those of a fusiform muscle. The arrangement of pinnate muscle fibers can be single or double, as in muscles of the forearm, or multipinnate, as in the gluteus maximus or deltoid.
A nerve can stimulate impulses to several muscle fibers. When muscle fibers are grouped they form a single muscle group like the biceps.
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
Cardiac muscle fibers are arranged in a crisscross pattern, allowing for efficient contraction and relaxation of the heart. This arrangement helps coordinate the pumping action of the heart and ensures effective blood flow throughout the body.
This type of muscle arrangement is called pennate. Pennate muscles maximize the number of muscle fibers in a given space, allowing for greater force production. Examples of pennate muscles include the deltoid and gastrocnemius.
Skeletal muscles contain elongated muscle fibers arranged in sheets and have multiple nuclei. Smooth muscles and cardiac muscles also have elongated cells, but they are not arranged in sheets and do not have multiple nuclei in each cell.
Muscle cells are organized into bundles called fascicles. Within each fascicle, muscle cells are arranged in parallel to each other. Individual muscle cells, or muscle fibers, are long and cylindrical in shape. This arrangement allows for efficient contraction and force generation.

Yes, though all of them are not exactly strong.
In smooth muscle these transitionally alternating muscle fibers help to serve the actions of peristalsis. As the circular fibers contract the tube (lumen) constricts and as the longitudinal fibers contract it opens up the lumen.
short fibers, arranged obliquely to their tendons
The striations in muscle fibers are caused by the arrangement of contractile proteins within the fibers. These proteins, primarily actin and myosin, overlap and interlock in a regular pattern, giving the muscle fibers a striped appearance when viewed under a microscope.

In forming whole muscles, individual muscle fibers are arranged in bundles, or fascicles, held together by fibrous connective tissue.Answer is Fascicles.
