Which brain area acts to screen all incoming sensory data?
Correct answer: A. Thalamus
- A. Thalamus
- B. Hypothalamus
- C. Cerebral cortex
- D. Cerebellum
Explanation
The thalamus serves as a sensory relay station in the brain, filtering and directing incoming sensory information to the appropriate areas of the cerebral cortex for further processing. By screening sensory data, the thalamus ensures that only relevant information is transmitted to higher brain regions, optimizing cognitive functioning and perception.

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.
