A) receptor to the spinal cord.
B) receptor to the brain.
C) spinal cord through the brainstem to the thalamus.
D) thalamus to the cerebral cortex.
E) spinal cord to cerebellum.
Ascending Pathway
Neural paths that transmit sensory information from the body to the brain.
Secondary Neuron
A neuron that receives a synaptic input from primary neurons and transmits the signal to other neurons or muscles.
Thalamus
Large mass of gray matter that forms the larger dorsal subdivision of the diencephalon.
- Pinpoint the routes and mechanisms critical for sensing and motor function regulation.

Final Answer :
C
Explanation :
In an ascending pathway, the axons of the secondary neuron typically travel from the spinal cord, through the brainstem, to the thalamus, where they synapse before information is relayed to the cerebral cortex. This pathway is crucial for processing sensory information.
