Frogs have a highly developed nervous system that consists of a brain, spinal cord and nerves. Many parts of frog brains correspond with those of humans. It consists of two olfactory lobes, two cerebral hemispheres, a pineal body, two optic lobes, a cerebellum and a medulla oblongata. Muscular coordination and posture are controlled by the cerebellum, and the medulla oblongata regulates respiration, digestion and other automatic functions. The relative size of the cerebrum in frogs is much smaller than it is in humans. Frogs have ten pairs of cranial nerves which pass information from the outside directly to the brain, and ten pairs of spinal nerves which pass information from the extremities to the brain through the spinal cord. [76] By contrast, all amniotes (mammals, birds and reptiles) have twelve pairs of cranial nerves. [79] Close-up of frog's head showing eye, nostril, mouth, and tympanum Sight G. Carnevale1 & T.W.

Direct development, where eggs hatch into juveniles like small adults, is also known in many frogs, for example, Ischnocnema henselii, [143] Eleutherodactylus coqui, [144] and Raorchestes ochlandrae and Raorchestes chalazodes.

In fresh water, frogs have a body salt content much higher than the surrounding water and therefore tend to absorb water by osmosis and lose salts by diffusion through the skin. However, they have a physiology that compensates for this and they survive. In seawater, they would be immersed in a medium much more concentrated than their body fluids, especially blood; they would lose water rapidly and gain salts, processes for which their physiology cannot compensate, so they would die.

Some frogs, such as the poison dart frogs, are especially toxic. The native peoples of South America extract poison from these frogs to apply to their weapons for hunting, [185] although few species are toxic enough to be used for this purpose. At least two non-poisonous frog species in tropical America ( Eleutherodactylus gaigei and Lithodytes lineatus) mimic the colouration of dart poison frogs for self-protection. [186] [187] Some frogs obtain poisons from the ants and other arthropods they eat. [188] Others, such as the Australian corroboree frogs ( Pseudophryne corroboree and Pseudophryne pengilleyi), can synthesize the alkaloids themselves. [189] The chemicals involved may be irritants, hallucinogens, convulsants, nerve poisons or vasoconstrictors. Many predators of frogs have become adapted to tolerate high levels of these poisons, but other creatures, including humans who handle the frogs, may be severely affected. [190]
