Term
| where is the direction of ankle extension during forward sway? |
|
Definition
| ankle extension opposes the sway |
|
|
Term
| What happens to ankle extension in backward sway? |
|
Definition
| ankle extension INCREASES sway |
|
|
Term
| What happens when the stretch reflex is served to stabilize posture? |
|
Definition
| the reflex is FACILITATED |
|
|
Term
| reflex served to destabilize posture |
|
Definition
| the reflex becomes progressively weaker |
|

|
Definition
| hindlimb extension and forelimb flexion |
|
|
Term
| Turning of the head to which direction increases stability during lateral movements to the right? |
|
Definition
| right. this is done by forelimb and hindlimb extension on that side |

|
|
Term
| what happens when the head is turned to the left? |
|
Definition
the left arm extended
right arm flexion
due to utricle stimulation |

|
Definition
| cervical (arms) and lumbar (legs) enlargements |
|
|
Term
| how is walking accomplished in the spinal cord? |
|
Definition
| coactivation of alpha and gamma motoneurons |
|
