Histological and histochemical studies on the innervation of the respiratory organs of Calotes versicolor Daud. (Agamidae, Lacertilia).
A study on the innervation of the respiratory organs of Calotes versicolor has been made using cholinesterase and silver reduction techniques. The tracheal and bronchial plexuses have been described. A number of nerve terminations along with synapses are reported. ChE activity has been observed on the periphery of the alveoli which is believed to be of importance in controlling the acetylcholine level, acting as a general tissue enzyme to prevent excessive accumulation of acetylcholine. Vascular nerve supply has been found to be largely of vagal origin.
