[Characteristics of adrenergic innervation of the somatic muscles].
The aim of the present study was luminescent-histochemical study of efferent adrenergic nervous apparatus of cross-striated somatic muscles. The adrenergic innervation of human laryngeal muscles--m. thyroarytenoideus internus (m. vocalis), m. cricoarytenoideus posterior (m. posticus)--was studied in comparison with the innervation of m. pectoralis major (material obtained at 18 early autopsies) and m. gastrocnemius of the frog Rana temporaria (17 animals). In frozen sections of muscles, treated with the glyoxilic acid solution, adrenergic varicose terminals were demonstrated that were situated directly among the cross-striated muscle fibers. The problem of neuroeffector relations in the autonomic nervous system is discussed.
