  • Title: Ultrastructural variations in frog muscles subjected to sciatectomy.
    Author: Somasekhar T, Ramamohan Y, Krishnamoorthy RV.
    Journal: Indian J Exp Biol; 1989 Oct; 27(10):899-902. PubMed ID: 2635150.
    Abstract:
    Fine structural variations in two different types of muscles of frog (Rana cyanophlictis) subjected to sciatectomy were studied electronmicroscopically. Gastrocnemius muscle showed marked myofibrillar disarray and degeneration due to sciatectomy, while sartorius muscle was relatively less affected. The extent of sciatectomy induced fine structural variation was in proportion to the degree of denervation atrophy (as reflected by loss of wet muscle weight) in these muscles. Differences in the degree of degenerative changes in atrophying muscles may be attributed to variations in fiber type composition and stretch effects imposed during swimming movements.
