nose. 1. the part of the face that contains the nostrils and organs of smell and that functions as a passageway for air in respiration. 2. this part as the organ of smell. 3. the sense of smell. 4. the snout, muzzle, or proboscis of an animal.
Muscle fibers within the fascicle are surrounded by endomysium (320x). connective tissue, therefore, enclose and separate all parts of a skeletal muscle. This arrangement allows the parts to move somewhat independently. Also, many blood vessels and nerves pass through these layers.hese sections contain bundles of skeletal muscle fibers called fascicles (fasciculi). Each muscle fiber within a fascicle (fasciculus) lies within a layer of connective tissue in the form of a thin covering called endomysium (figs. 9.2 and 9.3).
Skeletal muscle is a secretory organ. Leukemia inhibitory factor (LIF), interleukin (IL)â4, ILâ6, ILâ7, and ILâ15 promote muscle hypertrophy. Myostatin inhibits muscle hypertrophy and exercise provokes the release of a myostatin inhibitor, follistatin, from the liver.keletal muscles are primarily characterized by their mechanical activity required for posture, movement, and breathing, which depends on muscle fiber contractions. However, skeletal muscle is not just a component in our locomotor system. Recent evidence has identified skeletal muscle as a secretory organ.
