Muscle
筋肉 (kin'niku)
Muscles are soft tissues composed of fibers capable of contracting to produce movement. There are three types: skeletal (voluntary movement), cardiac (heart), and smooth (involuntary organs). Muscle strains, cramps, and myalgia are common complaints. In Japan, sports injuries and occupational muscle strain are frequent reasons to visit orthopedic or rehabilitation clinics.
Muscle-related complaints are evaluated in the orthopedics or internal medicine department in Japan.
