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 muscle in which the fibers are arranged at an angle to a central longitudinal tendon has a arrangement?
Pennate.
Does a nerve provided impulses for many muscle fibers or just few?
A nerve can stimulate impulses to several muscle fibers. When muscle fibers are grouped they form a single muscle group like the biceps.
What arrangement of cardiac muscle fibers make the heart efficient?
The cardiac muscle is arranged spirally around the heart to make it more efficient.
What type of muscle fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
What is the function of the muscle fibers?
muscle fibers contract the muscles when stimulated.
How are the muscle cells arranged with respect to one another?
Muscle fibers are grouped into fascicles, these fascicles form a muscle. The fascicles are arranged in 3 basic patterns. Parallel fascicles are arranged length wise in a parallel form. Circular fascicles are arranged in rings in a concentric pattern. Pennate fascicles are arranged in a feather pattern, with muscles arranged like a feather attached to a tendon along its length.

Why are muscles arranged in circular and longitudinal layer?
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.
Are skeletal muscle fibers long and strong and arranged in bundles?
Yes, though all of them are not exactly strong.
What arrangement of cardiac muscle fibers make the heart efficient?
The cardiac muscle is arranged spirally around the heart to make it more efficient.
What is the muscle fiber arrangement in a pennate muscle?
short fibers, arranged obliquely to their tendons
What type of muscle fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
What gives muscle fibers their striations?
The units of contraction called sarcomeres give striated muscle this appearance. Smooth muscle also has sarcomeres but they are not as neatly arranged so they appear smooth.
What types of fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.

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