Nerve impulses are eventually propagated till they reach what part of the brain?

Nerve impulses from the sensory organs are transmitted to various parts of the brain for processing, and the thalamus plays a key role in relaying these signals. It acts as a central hub for sensory information, receiving impulses from the different sensory pathways and directing them to appropriate areas of the cerebrum for further processing and perception.

The medulla oblongata is primarily responsible for regulating autonomic functions and relaying signals between the spinal cord and higher brain regions, but it is not the primary site for the processing of sensory information. The cerebellum is mainly involved in coordinating voluntary movements and balance, while the cerebrum is where higher-order processes occur, including reasoning, emotions, and complex sensory processing. However, the thalamus is the crucial passage point for most sensory signals before they reach the cerebrum for interpretation, making it the correct answer.
