Reactive postural control refers to the ability of the body to quickly adjust and stabilize posture in response to unexpected disturbances or external forces. This process involves sensory feedback, neural pathways, and muscle activation to maintain balance and prevent falls.
Fixator
No, but skeletal muscle is.
Muscular System
The diaphragm muscle.
When there is apparent muscular weakness after a diagnosed stroke, the problem typically is not with the muscle, but with interruption of the neural pathways that access the muscle in question. As the stroke has killed off some of the neural connections to that muscle or muscles, weakness will appear until (and if) a sort of "re-routing" occurs and neural pathways are established once more.
What are the antagonist of sternocleidomastiod muscle?
The spinous processes of the vertebrae are origins and insertions for various postural muscles. A broken spinous process would likely result in significant pain and muscle aches due to improper alignment of the muscles.

Cells that are the same form tissues. Muscle cells form muscle tissue.
Postural changes at rest are compensated for by maintaining proper muscle tension and joint alignment to support the body's weight. The body adjusts muscle tone and activates appropriate postural muscles to maintain an upright position without the need for conscious effort. Additionally, the body may engage stabilizing reflexes to prevent excessive swaying or leaning during periods of rest.
