Somatosensory feedback in balance primarily provides information about:

• A. External forces
• B. Body parts relative to each other
• C. Visual cues
• D. Temperature

Answer: (B)

Somatosensory feedback, or proprioception, provides information about where your body parts are in relation to each other. In balance, receptors in muscles, tendons, and joints sense joint angles, muscle length, and limb movement, giving the brain an internal map of body configuration to generate the appropriate postural adjustments. Visual cues and the vestibular system contribute to balance by providing information about the environment and head orientation, while temperature is not involved in balance control. So this feedback most directly describes the relative position of body parts.
