Question

Сравните головной мозг рыбы лягушки змеи голубя кошки человека. сделайте вывод

Answer 1

Головной мозг лягушки, как и других амфибий, характеризуется следующими особенностями по сравнению с рыбами: а) прогрессивным развитием головного мозга, выразившимся в обособлении парных полушарий продольной щелью и развитием в крыше мозга серого вещества древней коры (archipallium); б) слабым развитием мозжечка; в) слабой выраженностью изгибов головного мозга, благодаря чему промежуточный и средний отделы ясно видны сверху.

Answer 2

Comparing the Brain of Different Animals

Let's compare the brains of fish, frog, snake, pigeon, cat, and human.

Fish Brain: - The brain of a fish is relatively simple and lacks the complex structures found in the brains of higher vertebrates. - It consists of the hindbrain, midbrain, and forebrain, but lacks the cerebral cortex found in mammals.

Frog Brain: - The frog brain is also relatively simple and consists of the same basic regions as the fish brain, including the hindbrain, midbrain, and forebrain. - It lacks the complex cerebral cortex found in mammals.

Snake Brain: - The brain of a snake is relatively small and simple compared to mammals. - It consists of the same basic regions as the brains of fish and frogs, but lacks the complex structures found in mammalian brains.

Pigeon Brain: - The pigeon brain is more complex than the brains of fish, frogs, and snakes, but still lacks the advanced structures found in mammalian brains. - It has a well-developed visual system and a relatively large cerebellum, which is involved in motor control.

Cat Brain: - The brain of a cat is more complex than those of fish, frogs, snakes, and pigeons. - It has a well-developed cerebral cortex, which is responsible for higher cognitive functions such as perception, decision-making, and language processing.

Human Brain: - The human brain is the most complex and advanced among the compared animals. - It has a highly developed cerebral cortex, which is responsible for advanced cognitive functions such as reasoning, problem-solving, and abstract thinking.

Conclusion

The brains of different animals vary in complexity and size. While the brains of fish, frogs, and snakes are relatively simple and lack the advanced structures found in mammalian brains, the brains of pigeons and cats show some degree of complexity, with the cat brain being more advanced. However, the human brain stands out as the most complex and advanced, with a highly developed cerebral cortex responsible for sophisticated cognitive functions. This comparison highlights the evolutionary progression of brain complexity across different species.
