The thickness of the enamel of dogs and cats was measured in 194 teeth. The enamel was found to be thinner than that of human teeth, varying in thickness from 0.1mm-1mm. The "enamel bulge" coronal to the cemento-enamel junction does not consist of a thickened area of enamel.
The order Rodentia is vast, encompassing a large number of species with significant anatomical variations developed during natural adaptation to differing habitats. Many veterinarians have little knowledge of the anatomy of species other than the commoner domestic large herbivores and small carnivores. Clinicians require a basic knowledge of the relevant anatomy of species they are likely to be asked to treat. This article provides sufficient working knowledge of the oral and dental anatomy of those rodents commonly kept as pets to enable veterinarians to interpret clinical and radiographic findings when investigating suspected dental disease.
The lagomorphs most commonly encountered as pets are rabbits. There are many breeds of domestic rabbit, varying from dwarf varieties with an adult weight of under one kilogram to giants weighing 10 kg. This article provides a working knowledge of the dental anatomy and physiology of rabbits so that veterinarians can interpret clinical and radiographic findings when investigating rabbits with suspected dental disease.

The influence of increased pulmocutaneous arterial systolic pressure on amphibian lymph heart activity was determined in Bufo marinus. Arginine vasotocin-induced increases in systolic arterial pressure of greater than 0.5 kPa significantly (P<0.0002) decreased lymph heart rate. Denervation of the recurrent laryngeal nerve led to an increase in arterial pressure of 3.88 kPa in test animals compared to control animals. Denervation abolished lymph heart response to increased arterial pressure for an average of 38 min. Direct stimulation to the recurrent laryngeal nerve stopped lymph heart activity without an increase in arterial pressure. These data indicate that baroreceptors in the pulmocutaneous artery can decrease lymph heart rate during periods of either direct stimulation or elevated arterial pressure. The data also support lymph hearts as effectors for aortic and carotid baroreceptors.
