Have the patient repeat this movement with the other foot. An inability to perform this motion in a relatively rapid cadence is abnormal. The heel to shin test is a measure of coordination and may be abnormal if there is loss of motor strength, proprioception or a cerebellar lesion. If motor and sensory systems are intact, an abnormal, asymmetric heel to shin test is highly suggestive of an ipsilateral cerebellar lesion.
Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. Example: Indole Acetic Acid (IA). Auxin is a plant hormone produced in the stem tip that promotes cell elongation.
Auxin is the first group of plant hormones that was discovered by scientists in 1926. Auxin is mainly present in the form of indole acetic acid (IAA) in plants. However, there are other chemical compounds also found in plants that exhibit functions similar to auxins.One of the major functions of the IAA is to stimulate cell elongation of the young shoots.uxin is the first group of plant hormones that was discovered by scientists in 1926.
