Evidence that cell bodies of non-cholinergic, excitatory neurones which supply the smooth muscle of the XXXX rectum are located in the @entity21 of Remak's nerve.

1. A pharmacological investigation of the distribution of non-cholinergic excitatory nerve cell bodies was performed on the @entity1573 's isolated perfused rectum with attached Remak's nerve supply. 2. Electrical stimulation of Remak's nerve trunk produced a contraction and a discharge of action potentials in the nerve branches which supply the smooth muscle of the rectum. Both responses were virtually blocked by @entity4033 when applied via the caudal mesenteric artery. 3. The contractile effect following stimulation of the nerve trunk was inhibited more effectively by @entity4033 when application was restricted to the trunk rather than to the intestine. 4. The contractile effect of stimulating the nerve branches was unaffected by @entity4033 . 5. It is concluded that ganglionic transmission, which is mediated by nicotinic receptors, occurs in the @entity21 of Remak's nerve but not in @entity21 of the enteric plexuses. Therefore, cell bodies of the postganglionic neurones which are considered to be non-cholinergic are located in Remak's nerve @entity21 .
