Spinal reflexes

Reflex	Sensory afferent	Proposed function
Myotactic (stretch) reflex	Muscle spindle - 1a afferent	Muscle tone maintenence, antigravity/posture movement
Inverse myotactic	Golgi tendon organ - 1b afferent	Controls tension to avoid overcontraction/overstretch
Flexor withdrawal	Free nerve endings - A-delta + C afferent	Withdraws limb from offending stimuli, maintains balance during withdrawal
