E2a–E2c). At the outside of each section is a layer of muscle fibers extending longitudinally along the gut; these fibers are cut transversely giving this region a granular appearance when viewed under low power. The fibers are arranged in bundles imperfectly outlined by septa of connective ...

In subject area: Neuroscience A fusiform muscle, also known as a strap muscle, refers to a type of muscle that has a parallel-fiber arrangement. This means that the muscle fibers are arranged parallel to the longitudinal axis of the muscle. Examples of fusiform muscles include the sartorius, ...
Individual muscle cells are called muscle fibers. Skeletal muscle is made up of thousands of muscle fibers arranged in parallel bundles. Each fiber is thinner than a hair and can measure up to 12 in (30 cm) long. HOW DOES A MUSCLE CONTRACT? A muscle fiber is made up of myofibrils, wh...

Smooth muscle myofilaments are usually not combined into separate myofibrils but are arranged along the length of the fiber in the form of numerous single actin filaments. There is no ordered system of myosin filaments in smooth muscle cells. Tropomyosin A fibers in the smooth musculature of ...
are arranged along the length of the fiber in the form of numerous single actin filaments. There is no ordered system of myosin filaments in smooth muscle cells. Tropomyosin A fibers in the smooth musculature of mollusks appear to play a major role in performing the obturator function (closing...

As its name suggests, skeletal muscle is linked to bone by bundles of collagen fibers known as tendons. Skeletal muscle is made up of individual components known as muscle fibers. These fibers are long, cylindrical, multinucleated cells composed of actin and myosin myofibrils repeated as a ...
Myofilaments are arranged in repeating units called: -Sacromeres Sacromeres are composed of: -Overlapping thick (myosin) and thin (actin) filaments Parts of a sacromere: -Z discs -I bands -A bands -Connectin Parts of sacromere: Z discs ...
