Question: interoceptors detect
Answer:
visceral (internal) senses

Answer:
baroreceptors
Question: proprioceptors
Answer:
monitor the position and movement of skeletal muscles and joints
(where are we in space? what muscles are contracting? Where and how fast?)

Answer:
smell, taste, vision, hearing, equilibrium
