STRUCTURE DISTRIBUTION AND DENSITY OF THE MUSCLE SPINDLES IN GASTROCNEMIUS MUSCLE OF Melopsittacus undulates
Department of Zoology, Faculty of Science, Benghazi University, Libyia.
Abstract
Five adult Melopsittacus undulates birds were used to study the morphology, density and distribution of the muscle spindles in gastrocnemius muscles in both right and left legs, employing serial transverse histologic sections stained with hematoxylin and eosin. The density of such muscle spindles was 100.95/gm. They were scattered within the whole muscle. Each spindle showed four to less intrafusal muscle fibers and blood capillaries and enclosed in outer capsule. A complex spindle was seen in paired arrangement in the belly of the muscle.
