| Abstract | ||
| This study included acknowledge of the changes associated with the growth of skeletal muscle in the forelimbs in rats , as tested three muscles: Flexors and Extensors muscles and Triceps Brachii in 30 male of the laboratory rats and in three age groups , namely, (2 ) , ( 12 ) and ( 24) a month to see the changes that appear with aging in muscle weights and number and diameters of muscle fibers. and its constituent .the study revealed the following results: -1in the first age group (2) month was measured the weight of body and weight of muscle of rats. And calculate the number of muscle fibers in muscles. And also measure muscle fiber diameters. -2In the second age group ( 12) a month showed an three muscles increase in weight and fiber diameters , as the number of fibers increase in the Triceps Brachii muscle while decreased in each of the Flexors and Extensors muscles . 3-In the third age group ( 24) month showed an increase in three muscle weight. Increased muscle fiber number in the Triceps Brachii while decreased in the Flexors and Extensors muscles . and decreased fiber diameters in the Triceps Brachii and increased in the Flexors and Extensors muscles. | ||
