Frogs
A frogs central nervous system is made up of two organs, a brain and a spinal cord. Its brain is contained in a bony structure known as a a brain box or a cranium that protects the brain from ouitside forces. The brain consists of a pair of ccipital condyles and is divided into three parts- the fore brain, mid brain, and hind brain.
Fore-Brain
Consists of olfactory lobes, a pair of cerebral hemispheres and unpaired dienecephalon. The olfactory controls the frog's sense of smell.
Mid-Brain
Contains a pair of obtic lobes used in vision
Hind-Brain
Consists of cerebellum that maintanes the balance of the frog and its euillibrium. Modulla helps in the regulation of respiration and digestion
The peripheral nervous sytem comprises of cranial and spinal nerves. Ten pairs of cranial nerves run from the brain and innervate to the different parts of the body to send information. Ten spinal nerves are used to send information from extremities to the brain through the soinal cord.
A frog also has an autonomic nervous which is made up of sympathetic and parasympathetic chains of ganglia.
