cruciate musclea muscle in which the fiber bundles are arranged in the shape of an X. cutaneous musclestriated muscle that inserts into the skin. deltoid musclethe muscular cap of the shoulder, often used as a site for anintramuscularinjection. See appendix 3-4. ...
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 ...
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...
The arrangement of airway smooth muscle varies according to its location in the airway tree. In the posterior aspect of the adult trachea it forms the trachealis, a unified layer of thick unbranched bundles from the larynx to the carina in which the parallel smooth muscle fibers are orientated...
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...

A skeletal muscle consists of a bundle of long fibers running the length of the muscle.The bundles of fibers are arranged in a regular pattern—a repeating pattern of light and dark bands.This pattern is called striation, and skeletal muscle is also known as striated muscle.When a muscle con...
Skeletal muscle is a highly organized tissue composed of bundles of muscle fibers called myofibers which contain several myofibrils. Each myofiber represents a muscle cell with its basic cellular unit, the sarcomere. Bundles of myofibers form fascicles, and bundles of fascicles form muscle tissue. ...
Which of the following has fibers that are arranged in spiral or figure 8 bundles? a. cardiac muscle b. skeletal muscle c. smooth muscle Which of the following is arranged in layers, circular and longitudinal? a. cardiac muscle b. skeletal muscl...
