The Brain of Frog
-
-
- The brain is lying inside the cranium of the skull and it is well protected there.
- It is surrounded by two meninges. The outer one is called piamater and the inner one is called duramater.
- The whole brain is differentiated into three parts. They are the prosencephalon (forebrain), mesencephalon (midbrain), and rhombencephalon (hindbrain).
- The anteriormost part is called the prosencephalon which is subdivided into two parts and they are telencephalon and diencephalon.
- The telencephalon comprises of a pair of small olfactory lobes and a pair of cerebrum or cerebral hemispheres. Olfactory lobes are responsible for the sense of smell.
