Intrinsic innervation of the uterus in guinea pig and rat.
The pattern of distribution of cholinergic and adrenergic nerves in the uterus of albino rats and guinea pigs was examined histochemically. In the albino rat, the uterus was found well-innervated by both adrenergic and cholinergic nerves with a clear regional variation. Dense innervation was demonstrated at the tubal and cervical ends of the uterus and in the cervix. Cholinergic nerves supplying the glands were more numerous than the adrenergic nerves which were relatively few. In the guinea-pigs, the uterus was richly innervated by adrenergic nerves with a clear regional variation. No cholinesterase-positive nerves or nerve cells were demonstrated.
