Is smooth muscle branched or unbranched?
Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles. Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks. Its contraction is not under voluntary control.Click to see full answer.

Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles. Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks. Its contraction is not under voluntary control.Click to see full answer. Similarly, you may ask, is smooth muscle branched?Smooth muscle has no striations, is not under voluntary control, has only one nucleus per cell, is tapered at both ends, and is called involuntary muscle. It has one nucleus per cell, is branched, and is distinguished by the presence of intercalated disks.Additionally, what is the function of smooth muscle? Functions of Smooth Muscles Smooth muscles move food through the digestive tract. In one’s eye the pupillary sphincter muscles is responsible for shrinking the size of the pupil. In arteries, smooth muscle movements maintain the arteries’ diameter. Smooth muscle regulates air flow in lungs. Subsequently, question is, are muscle cells branched? Answers for Critical Thinking Questions Cardiac and skeletal muscle cells both contain ordered myofibrils and are striated. Cardiac muscle cells are branched and contain intercalated discs, which skeletal muscles do not have.What are the basic structural differences between skeletal cardiac and smooth muscle?Figure 1: Muscle Types. Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not. Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary.
