what are the general senses of muscle spindles?
proprioception (sense of muscle length)
Where are general sense organs found?
almost every part of the body
Where are the general sense organs concentrated?
in the skin
Explain what make proprioceptors a little different. Where are they found?
They are receptors in the tendons and because of this they lare located in the skeletal muscles
