TONIC NECK REACTION

• With animal in a normal standing position, the head is elevated and neck is extended.
• The normal reaction is slight extension of thoracic limbs and slight flexion of pelvic limbs.
• Lowering the head causes thoracic limbs to flex and pelvic limbs to extend.
• Turning the head to the side causes a slight extension of ipsilateral thoracic limb and slight flexion of the contra lateral thoracic limb.
