Abstract
1. 1. The anatomy and innervation of the heart in the slug Limax maximus are described. 2. 2. The heart is myogenic and is reflexively modulated by tactile stimulation of the body surface. 3. 3. Pharmacological data suggest that cardioexcitation is serotoninergic and cardioinhibition cholinergic, although both ACh and 5-HT have biphasic effects depending on concentration. 4. 4. Cardioexcitatory and cardioinhibitory areas of the visceral ganglion were identified and modulation of heart rate by single cells demonstrated.
