Abstract
Parasympathetic denervation reduced the size of the submandibular and major sublingual glands of the rat by about 30%. Calcium concentration was unchanged in the submandibular gland, but was reduced significantly in the sublingual gland. Sympathetic denervation elicited an increase in calcium concentration in the submandibular gland but not in the sublingual gland. Weight of the submandibular gland was reduced slightly, but that of the sublingual gland was not modified. After combined parasympathectomy and sympathectomy, both glands showed a significant decrease in size and calcium concentration.
