Question Answer
Role of Touch in Motor Control 1. Influences movement accuracy; 2. Movement consistency; 3. Movement force; 4. Movement distance
Muscle Spindles Detect changes in muscle length
Golgi Tendon Organs Located in MTJ; Detect tension or force
Joint Receptors Detect changes in force and joint rotation
Visual Dominance The reliance on vision in performance
Focal / Central Vision Performed by cones and fovea; Range of 2-5 deg; Focus on objects in centre of field of vision; Less effective in dark; requires conscious processing.
Ambient / Peripheral Vision Performed by rods; Range of 200x160deg field of vision; More effective in low light; Mostly sub-conscious
Cornea Clear surface
