Smell and Taste - Taste - Central taste pathways

4 important questions on Smell and Taste - Taste - Central taste pathways

List the 5 step pathway involved in communicating taste signals

  1. Tongue
  2. from nerves VII and XI
  3. at the nucleus of the solitary tract (gustatory nucleus) the axons travel up
  4. ventral posterior medial nucleus of thalamus
  5. gustatory cortex into insula and frontal operculum regions

Name the axons of the taste bud that become the anterior ⅔ of the tongue?

Cranial nerve VII "facial"

Name the axons of the taste bud that become the posterior ⅓  of the tongue?

Cranial nerve XI "glossopharyngeal"
