Weakness of the iliacus, quadriceps and sartorius muscles as well as the decreased patellar reflex supported this differential diagnosis.
Martinez-Pereira & Rickes observed that in the chinchilla (Chinchilla lanigera), the femoral nerves issued varied branches to the major and minor psoas, femoral quadriceps, gracilis, pectineus and sartorius muscles, resembling in part the results obtained in the present investigation, and those obtained by Lopes et al.
However, activation of flexor muscles during walking in decerebrate cats has been associated with afferents drive from the sartorius muscle [30-31].
Sartorius muscle afferents influence the amplitude and timing of flexor activity in walking decerebrate cats.
The morphological and morphometric analysis allow us suggest descriptive parameters for these muscles the histological analysis allow us conclude the gracilis muscle and sartorius muscle fibers are not linked, but kept together by a conjunctive tissue, thus, being inserted into the medial side of the tibia.
