Which of these is best developed in birds?
Correct answer: A. Cerebellum
- A. Cerebellum
- B. Cerebrum
- C. Medulla
- D. Thalamus
Explanation
The cerebellum is the part of the brain that is best developed in birds. The cerebellum is responsible for motor coordination and balance, and it plays a critical role in the control of complex movements, such as those involved in flying. The cerebellum in birds is relatively larger and more complex than in other vertebrates, which is thought to be related to their advanced motor skills and ability to perform complex aerial maneuvers. The cerebellum in birds is also involved in the control of vocalizations and is thought to be important for the production and learning of bird songs.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
