Answer:
foot, spinal cord, thalamus, parietal lobe
Explanation:
Natriuretic peptide (BNP), is an example of a neurotransmitter, which are responsible for conveying different itching sensations from the skin or foot to the spinal cord and ultimately into the brain. When the brain receives the signals from the nerves, it interprets it and further relays the message which appears as the feeling of sensation we do experience.
