We had a discussion about sensory detail today and the topic turned to the fact that there are actually twenty one (or more) recognized senses.
The classic five senses:
The expanded list of 21:
- Sweet taste
- Sour taste
- Salty taste
- Bitter taste
- Umami taste (the meaty taste found in soy sauce)
- Proprioception (joint position)
- Kinaesthesis (movement)
- Blood pressure
- Blood oxygen content
- Cerebrospinal fluid pH
- Plasma osmotic potential (thirst)
- Artery-vein glucose difference (hunger)
- Lung inflation.
The trick, of course, is to work sensory details in to your story to give the world a richer feel. An interesting challenge would be to write a short story that engages all twenty-one senses.
