Muscle Tissues. There are three types of muscle in animal bodies: smooth, skeletal, and cardiac. They differ by the presence or absence of striations or bands, the number and location of nuclei, whether they are voluntarily or involuntarily controlled, and their location within the body.

Chapter Review. Muscle is the tissue in animals that allows for active movement of the body or materials within the body. There are three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle. Most of the body’s skeletal muscle produces movement by acting on the skeleton. Cardiac muscle is found in the wall of the heart ... Which of the following is a characteristic of smooth muscle? a) It can be controlled voluntarily. b) Smooth muscle cells contain actin and myosin. c) Muscle contraction does not depend on calcium ions. d) It has striations and sarcomeres. b) Smooth muscle cells contain actin and myosin. Which type of contraction causes a skeletal muscle to shorten? Nuclear Positioning, but Not Number Changes During the Growth and Differentiation of Striated Muscles. In Drosophila, multinucleated myotubes are formed by fusion of a fixed number of myoblasts to a muscle founder cell; the myotubes subsequently migrate and attach to a specific tendon cell. 22 Muscle striation takes place at a later developmental stage after the myotube has established its ...Skeletal muscle histology. This type of tissue is found in skeletal muscles and is responsible for the voluntary movements of bones. Skeletal muscle is an excitable, contractile tissue responsible for maintaining posture and moving the orbits, together with the appendicular and axial skeletons. It attaches to bones and the orbits through tendons.

Cell Shape: Skeletal muscle cells are long and cylindrical, while cardiac muscle cells are branched and cylindrical, and smooth muscle cells are spindle-shaped.The muscle cell, or myocyte, develops from myoblasts derived from the mesoderm. Myocytes and their numbers remain relatively constant throughout life. Skeletal muscle tissue is arranged in bundles surrounded by connective tissue. Under the light microscope, muscle cells appear striated with many nuclei squeezed along the membranes.

These choices were dictated by anatomical accessibility. In the EDL the fibres had a nuclear density of 30–57 nuclei mm −1, while in the soleus fibres nuclear density ranged from 35 to 77 nuclei mm −1. Given a fibre length of 4–6 mm, this gives a total of one- to a few hundred nuclei per cell.
