2. Human skeletal changes due to bipedalism - Wikipedia

   en.wikipedia.org/wiki/Human_skeletal_changes_due...

   This muscle is much smaller in chimps, which shows that it has an important role in bipedalism. When humans run, our upright posture tends to flex forward as each foot strikes the ground creating momentum forward. The gluteus muscle helps to prevent the upper trunk of the body from "pitching forward" or falling over.

5. Postural Control - Wikipedia

   en.wikipedia.org/wiki/Postural_Control

   Postural control refers to the maintenance of body posture in space. The central nervous system interprets sensory input to produce motor output that maintains upright posture. [1] Sensory information used for postural control largely comes from visual, proprioceptive, and vestibular systems. [2] While the ability to regulate posture in ...

6. Righting reflex - Wikipedia

   en.wikipedia.org/wiki/Righting_reflex

   Righting reflex. The righting reflex, also known as the labyrinthine righting reflex, or the Cervico-collic reflex; is a reflex that corrects the orientation of the body when it is taken out of its normal upright position.

7. Balance (ability) - Wikipedia

   en.wikipedia.org/wiki/Balance_(ability)

   Balance (ability) Balance in biomechanics, is an ability to maintain the line of gravity (vertical line from centre of mass) of a body within the base of support with minimal postural sway. [1] Sway is the horizontal movement of the centre of gravity even when a person is standing still. A certain amount of sway is essential and inevitable due ...
