GROSS ANATOMY

Detailed explanation-1: -The amphibian brain is less developed than that of reptiles, birds, and mammals, but it is morphologically and functionally similar to a fish. Amphibians are thought to be capable of feeling pain. The cerebrum, midbrain, and cerebellum are all equal portions of the brain.

Detailed explanation-2: -The cerebellum is apparent between the medulla and midbrain. It is curiously small in all amphibians. It is not clear whether this is a primitive trait or the result of a secondary reduction. These brain areas are relatively conserved across amphibian groups in their size and general appearance.

Detailed explanation-3: -The reptilian brain, the oldest of the three, controls the body’s vital functions such as heart rate, breathing, body temperature and balance. Our reptilian brain includes the main structures found in a reptile’s brain: the brainstem and the cerebellum.

Detailed explanation-4: -The oldest layer of the brain is called the reptilian brain. It is composed of the brainstem (medulla, pons, cerebellum, midbrain, globus pallidus, and olfactory bulbs) – the structures that dominate in the brains of snakes and lizards.

Detailed explanation-5: -On average, the brains and nervous systems of amphibians are less well-developed than those found in reptiles. They tend to grow a smaller cerebrum and cerebellum, which affect things like motor function, thought, and speech.
