How does the brain keep the body upright?

The brain applies muscular force at all times to keep the body standing. This is a complex task, involving the inner ears, eyes, and neck, body and leg muscle spindles, as well as nerve endings in the feet, to keep the rather unstable human structure in dynamic equilibrium. Without active control from the head, the body cannot stand upright.

Why did humans evolve to walk upright?

In the 1980s, Peter Rodman and Henry McHenry, both at the University of California, Davis, suggested that hominids evolved to walk upright in response to climate change. As forests shrank, hominid ancestors found themselves descending from the trees to walk across stretches of grassland that separated forest patches.

What is the role of the skeleton in movement?

Movement – the skeleton allows movement of the body as a whole and its individual parts. The bones form joints and act as levers, allowing muscles to pull on them to produce movement. The bones of the skeleton provide surfaces for the attachment of muscles.
