Which of the following structures is part of the brainstem and is responsible for relaying information between the cerebrum and the cerebellum?
A
Corpus callosum
B
Pons
C
Cerebral cortex
D
Thalamus
Verified step by step guidance1
Identify the brainstem as the region of the brain that connects the cerebrum to the spinal cord and is responsible for basic life functions such as breathing and heart rate.
Understand that the brainstem consists of three main parts: the midbrain, pons, and medulla oblongata.
Recognize that the pons is a structure within the brainstem that serves as a bridge, relaying signals between the cerebrum (responsible for higher brain functions) and the cerebellum (responsible for motor control and coordination).
Eliminate the other options: the corpus callosum connects the two hemispheres of the cerebrum, the cerebral cortex is the outer layer of the cerebrum involved in higher cognitive functions, and the thalamus is a relay station for sensory information but is not part of the brainstem.
Conclude that the correct structure responsible for relaying information between the cerebrum and cerebellum within the brainstem is the pons.
