Chapter 41. Posture

1. Maintenance of posture is
1. Anticipatory
2. Reactive
3. Neither
2. The decerebrate cat is cut
1. At mid-thalamic level
2. At the inter-collicular level
3. Between the inferior colliculus and trapezoid body
4. None of the above
3. The state in which forces acting on the body are balanced so that it is able to progress through an intended movement without losing balance is called
1. Postural equilibrium
2. Static equilibrium
3. Dynamic equilibrium
4. If a human standing with his left side against a wall lifts the right leg straight out to the right, the first movement is
1. Of hips and shoulders to the left
2. Of the right foot to the right
3. Of the left hand outward
4. All of the above
5. Adaptive postural control is thought to be a function of
1. Cerebellum
2. Thalamus
3. Association cortex
6. A reflex not important in postural control is the
1. Vestibulocollic
2. Vestibulospinal
3. Cervicocollic
4. Cervicocortical
7. Activation of feed-back spinal stretch reflexes is primarily responsible for
1. Responses to an unexpectedly deep step
2. A dropped cat's ability to always land on its feet
3. Both
