Frog 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. By contrast, all amniotes (mammals,
Anatomy of the cerebellum would go to mossy fibers that synapse with granule and Golgi neurons with the granule cells then targeting Purkinje neurons via their excitatory parallel fibers. If the inferior olive it would go via excitatory climbing fiber inputs to Purkinje neurons. These return this output back to the cerebral cortex through the ventrolateral thalamus completing the loop. The corticopontocerebellar pathway is the largest pathway associated with the cerebellum. Arising in the cerebral cortex these fibers first terminate ipsilaterally in the pontine nuclei. Then the fibers decussate and form the middle cerebellar peduncle, terminating in the cerebellar cortex as mossy fibers. This
