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 a type of plant hormone involved in the formation of pegs in cucumber seedlings, which are a gravity-related physical trait, that develop between the plantâs roots and its stem. Understanding how plants sense gravity could enable new genetically modified variants that can grow in microgravity.he investigation examines how plants sense gravity, and how gravity affects plant hormone transportation, plant growth and root development, all of which are important for plant cultivation in space.
