The innervation of the primary bronchus of the chicken was studied with in vitro pharmacological techniques and with the electron microscope. The primary response of the smooth muscle to field stimulation is relaxation of the muscle and this is not blocked by adrenergic blocking agents. Excitatory cholinergic innervation can be demonstrated when the muscle is partially relaxed. Examination of the ultrastructure of the muscle and nerves shows numerous axon profiles filled with large granular… CONTINUE READING
