Cumulative sensory input to the CNS from all mechanoreceptors is called what?

• A. Mechanoreceptors
• B. Proprioception
• C. Tendons
• D. Golgi tendon organs

Answer: (B)

Proprioception is the body's awareness of its position and movement, produced by the integrated input from many mechanoreceptors throughout the body. The CNS continually sums signals from muscle spindles (which detect stretch), Golgi tendon organs (which sense tension), joint receptors (which sense joint angle), and skin mechanoreceptors (which sense contact and pressure). This collective information lets you know where each limb is in space and how it’s moving, even with eyes closed. Mechanoreceptors are the receptors themselves, and tendons or a single receptor type like Golgi tendon organs contribute part of the input, but the overall sense of body position and movement is proprioception.
