Cerebellum - the center of muscular coordination. This area of the brain is not well developed in amphibians. Medulla oblongata - controls some organ functions, such as heart rate and respiration. The ten pairs of cranial nerves extending directly from the brain insure that there is continuous communication between most areas of the brain. Eustachian tubes are extremely important to frogs.
Pulmonary respiration is many times more efficient than cutaneous respiration.
There are no amphibians that live in the ocean. Give reasons for this.
