What evidences prove that muscles, tendons and ligaments are supplied with sensory nerves?

Answer 1

Well, your ability to have the different movements - being able to walk,to run,to jump,to move your body all around would be more than enough evidences that the muscles,tendons and ligaments are supplied with sensory nerves.

Let's take this for example. Think about it: what happens to the person who was given spinal anesthesia? What happens to the person who got spinal cord injury? There will be paralysis on a certain body part that will result to loss of sensation and inability to walk. Try to recall what happened to the late "Superman"- Christopher Reeve (RIP).

Wouldn't those be enough evidences that muscles, tendons and ligaments are indeed supplied with sensory nerves?

Sensory input , from joint, tendon, and muscle receptors, (as well as those from the body surfaces and from internal organs) passes centrally through spinal cord. Injury on the spinal cord or anesthesia administration disrupts the relaying of the messages to the brain. So, the message may just be halted right there ending the communication with the brain.That would explain why the corresponding affected limbs or organs will loss its ability to move and to sense different factors.

Those sensory information arising from tendons, muscles, ligaments are called proprioceptive. That plays a very important role in locomotion or movements.

Answer 2

pinch yourself till you become blue, then you might feel the stimulation on your muscle. Have you strain your tendon? You should be able to feel the strain~ hopefully. For your ligaments... why not try to run, jump, or just be more athletic ;p Those (american) football players who had their ligaments removed couldn't play for a whilewhen their ligaments were floating around their knees--cus it hurts like hell even when they stand on their feet--.
