These are about 8 nm in diameter and, being the thinnest of the cytoskeletal filaments, are also called microfilaments. (In skeletal muscle fibers they are called thin filaments.) Some functions of actin filaments: 1  form a band just beneath the plasma membrane that.  provides mechanical strength to the cell.
The microfilaments are arranged so that the fibers appear to have stripes (striations) in them. These are also called voluntary muscles.. Smooth muscle is involuntary, and is not under conscious control; the muscles in your digestive system are smooth muscles.The cells are individual and are found in sheets instead of long fibers. (Cardiac muscle has characteristics of both, but are not referred to in the question).here skeletal muscle is voluntary, cardiac muscle is autorhythmic (beats involuntarily; generates its own action potentials). 3. Smooth muscle: refers to the muscles that are controlled involuntarily by the brain, like those attached to the base of hair follicles or in the walls of the gastro-intestinal tract.
Best Answer: voluntary muscles allow you to move them in voluntary muscles you have no control of voluntary muscle is muscle that we have control of.. skeletal muscles are voluntary muscle.. they are the reason you can flex your bicep, tricep, or any other movement..involuntary muscle is muscle that we have no control of.. cardiac and smooth muscle are involuntary muscles.. the muscle of the heart is involuntary.. you dont have to make your heart beat..it beats by itself..The voluntary muscles also called as skeletal muscles or striated muscles (presence of striation due to regular black and white bands).eport Abuse. voluntary muscle is muscle that we have control of.. skeletal muscles are voluntary muscle.. they are the reason you can flex your bicep, tricep, or any other movement.. involuntary muscle is muscle that we have no control of..
