Smooth muscle tissue has longitudinally and circularly arranged layers.

smooth muscle
Smooth muscle in the intestines.
The tunica interna of a muscular vein consists of an endothelium with a basal lamina, a thin subendothelial layer with smooth muscle cells, and a thin internal elastic membrane. Its tunica media has several layers of circularly arranged smooth muscle cells dispersed with collagen and elastic fibres. The smooth muscle cells may be arranged longitudinally in its tunica media. Its externa is generally thicker than its tunica media and has collagen fibres and a network of elastic fibres.
cardic
The middle layer of a vein is called the tunica media. It is made of circularly arranged smooth muscle and connective tissue (with a lot of elastin and collagen).
You have three layers in the heart. Outer layer is pericardium, middle layer is myocardium and inner layer is endocardium. Myocardium is composed mainly of cardiac muscles, connective tissue and blood vessels.
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.
Muscle fiber along the ventral surface of the frog is arranged in a very specific way. They are arranged in antagonistic pairs or groups that have opposing actions.

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.
